There is a growing need for introducing objective structured clinical examination (OSCE) as a part of radiology practical examinations in India. OSCE is an established, reliable, and effective multistation test for the assessment of practical professional skills in an objective and a transparent manner. In India, it has been successfully initiated and implemented in specialties like pediatrics, ophthalmology, and otolaryngology. Each OSCE station needs to have a pre-agreed "key-list" that contains a list of objective steps prepared for uniformly assessing the tasks given to students. Broadly, OSCE stations are classified as "manned" or "unmanned" stations. These stations may include procedure or pictorial or theory stations with clinical oriented contents. This article is one of a series of measures to initiate OSCE in radiology; it analyzes the attributes of OSCE stations and outlines the steps for implementing OSCE. Furthermore, important issues like the advantages of OSCE, its limitations, a strengths, weaknesses, opportunities, and threats (SWOT) analysis, and the timing of introduction of OSCE in radiology are also covered. The OSCE format in radiology and its stations needs to be validated, certified, and finalized before its use in examinations. This will need active participation and contribution from the academic radiology fraternity and inputs from faculty members of leading teaching institutions. Many workshops/meetings need to be conducted. Indeed, these collaborative measures will effectively sensitize universities, examiners, organizers, faculty, and students across India to OSCE and help successfully usher in this new format in radiology practical examinations.]]> http://www.ijri.org/article.asp?issn=0971-3026;year=2010;volume=20;issue=2;spage=83;epage=88;aulast=Agarwal Zainab Zaidi Paraclinical Indian Journal of Radiology and Imaging 2010 20(2):89-91doi:10.4103/0971-3026.63042 Indian Journal of Radiology and Imaging 10.4103/0971-3026.63042 http://www.ijri.org/article.asp?issn=0971-3026;year=2010;volume=20;issue=2;spage=89;epage=91;aulast=Zaidi http://www.ijri.org/article.asp?issn=0971-3026;year=2010;volume=20;issue=2;spage=89;epage=91;aulast=Zaidi202 89 91 http://www.ijri.org/article.asp?issn=0971-3026;year=2010;volume=20;issue=2;spage=89;epage=91;aulast=Zaidi Zainab Zaidi

The rapid changes in the healthcare system, with revolutionary advancements in imaging, along with the lack of any existing imaging standards in our country, have raised the need for an accreditation structure. The Quality Council of India (QCI) has therefore introduced standards for medical imaging services, focusing on the control of services, personnel, imaging processes and procedures, facility and environment, equipment, and documentation, as well as risk control and safety. This article deals briefly with the standards structured by the QCI for accreditation of imaging services.]]> http://www.ijri.org/article.asp?issn=0971-3026;year=2010;volume=20;issue=2;spage=89;epage=91;aulast=Zaidi Simone Perandini N Faccioli A Zaccarella TJ Re R Pozzi Mucelli Computers in Radiology Indian Journal of Radiology and Imaging 2010 20(2):92-97doi:10.4103/0971-3026.63043 Indian Journal of Radiology and Imaging 10.4103/0971-3026.63043 http://www.ijri.org/article.asp?issn=0971-3026;year=2010;volume=20;issue=2;spage=92;epage=97;aulast=Perandini http://www.ijri.org/article.asp?issn=0971-3026;year=2010;volume=20;issue=2;spage=92;epage=97;aulast=Perandini202 92 97 http://www.ijri.org/article.asp?issn=0971-3026;year=2010;volume=20;issue=2;spage=92;epage=97;aulast=Perandini Simone Perandini, N Faccioli, A Zaccarella, TJ Re, R Pozzi Mucelli

Computed tomography (CT) volumetric rendering techniques such as maximum intensity projection (MIP), minimum intensity projection (MinIP), shaded surface display (SSD), volume rendering (VR), and virtual endoscopy (VE) provide added diagnostic capabilities. The diagnostic value of such reconstruction techniques is well documented in literature. These techniques permit the exploration of fine anatomical detail that would be difficult to evaluate using axial reconstructions alone. Although these techniques are now widely available, many radiologists are either unfamiliar with them or do not fully utilize their potential in daily clinical practice. This paper is intended to provide an overview of the most common CT volumetric rendering techniques and their practical use in everyday diagnostics.]]> http://www.ijri.org/article.asp?issn=0971-3026;year=2010;volume=20;issue=2;spage=92;epage=97;aulast=Perandini Geeta Shah Bijal Jankharia Breast Indian Journal of Radiology and Imaging 2010 20(2):98-104doi:10.4103/0971-3026.63045 Indian Journal of Radiology and Imaging 10.4103/0971-3026.63045 http://www.ijri.org/article.asp?issn=0971-3026;year=2010;volume=20;issue=2;spage=98;epage=104;aulast=Shah http://www.ijri.org/article.asp?issn=0971-3026;year=2010;volume=20;issue=2;spage=98;epage=104;aulast=Shah202 98 104 http://www.ijri.org/article.asp?issn=0971-3026;year=2010;volume=20;issue=2;spage=98;epage=104;aulast=Shah Geeta Shah, Bijal Jankharia

Aims: To determine the prevalence, patterns of occurrence and variations of zygomatic air cell defects (ZACDs) using panoramic radiographs. Methods and Materials: Dental panoramic radiographs of 600 outpatients were examined to evaluate the variations and characteristics of ZACDs. Results: ZACDs were identified in 15 subjects out of 600, giving an overall prevalence of 2.5%. Seven ZACDs were seen in males and eight in females. Among the 15 ZACDs, nine were unilateral and six were bilateral. Conclusion: The overall prevalence of ZACD is relatively low in south Indian population and careful radiographic evaluation is needed to detect these entities.]]> http://www.ijri.org/article.asp?issn=0971-3026;year=2010;volume=20;issue=2;spage=112;epage=114;aulast=Srikanth Pradeep D Karlatti Swapnil Nagvekar TP Lekshmi Abhay S Kothari Head and Neck Indian Journal of Radiology and Imaging 2010 20(2):115-117doi:10.4103/0971-3026.63053 Indian Journal of Radiology and Imaging 10.4103/0971-3026.63053 http://www.ijri.org/article.asp?issn=0971-3026;year=2010;volume=20;issue=2;spage=115;epage=117;aulast=Karlatti http://www.ijri.org/article.asp?issn=0971-3026;year=2010;volume=20;issue=2;spage=115;epage=117;aulast=Karlatti202 115 117 http://www.ijri.org/article.asp?issn=0971-3026;year=2010;volume=20;issue=2;spage=115;epage=117;aulast=Karlatti Pradeep D Karlatti, Swapnil Nagvekar, TP Lekshmi, Abhay S Kothari

Background: Rectal cancer constitutes about one-third of all gastrointestinal (GI) tract tumors. Because of the high recurrence rates (30%) in rectal cancer, it is vitally important to accurately stage these tumours preoperatively so that appropriate surgical resection can be undertaken. MRI is the ideal technique for the preoperative staging of these tumours. Aim: To determine the accuracy of local T staging of rectal cancer with MRI, using histopathological staging as the gold. Materials and Methods: Forty consecutive patients admitted with rectal cancer over a period of 18 months were included in this retrospective study. MRI scans were performed prior to surgery in all patients, on 1.5T scanners. Two radiologists, with a special interest in gastrointestinal imaging reported all images. Two dedicated histopathologists reported the histology slides. The accuracy of preoperative local MRI T staging was assessed by comparison with postoperative histopathological staging. Results: There was agreement between MRI and histopathology (TNM) staging in 12 patients (30%). The sensitivity and specificity of MRI for T staging was 89% and 67% respectively. The circumferential resection margin (CRM) status was accurately staged in 94.1% of the patients. Conclusions: Preoperative staging with MRI is sensitive in identifying CRM involvement, which is the main factor affecting the outcome of surgery.]]> http://www.ijri.org/article.asp?issn=0971-3026;year=2010;volume=20;issue=2;spage=118;epage=121;aulast=Mulla Mukund D Rahalkar Anand M Rahalkar Dilip M Phadke Abdominal Indian Journal of Radiology and Imaging 2010 20(2):122-125doi:10.4103/0971-3026.63054 Indian Journal of Radiology and Imaging 10.4103/0971-3026.63054 http://www.ijri.org/article.asp?issn=0971-3026;year=2010;volume=20;issue=2;spage=122;epage=125;aulast=Rahalkar http://www.ijri.org/article.asp?issn=0971-3026;year=2010;volume=20;issue=2;spage=122;epage=125;aulast=Rahalkar202 122 125 http://www.ijri.org/article.asp?issn=0971-3026;year=2010;volume=20;issue=2;spage=122;epage=125;aulast=Rahalkar Mukund D Rahalkar, Anand M Rahalkar, Dilip M Phadke

Short rib polydactyly syndrome (SRPS) type 2 (Majewski syndrome) is a rare inherited, autosomal recessive, lethal skeletal dysplasia characterized by horizontally located short ribs, pre- and postaxial polysyndactyly, and micromelia, with characteristic short ovoid tibiae. There may or may not be visceral involvement. We report a case of SRPS type 2 that was diagnosed by antenatal USG at 28 weeks of gestation; the diagnosis was subsequently confirmed by postnatal radiography, fetal autopsy, and histopathology.]]> http://www.ijri.org/article.asp?issn=0971-3026;year=2010;volume=20;issue=2;spage=138;epage=142;aulast=Jutur P Gupta S Kumar Raju Sharma A Gadodia Obstetric Indian Journal of Radiology and Imaging 2010 20(2):143-146doi:10.4103/0971-3026.63041 Indian Journal of Radiology and Imaging 10.4103/0971-3026.63041 http://www.ijri.org/article.asp?issn=0971-3026;year=2010;volume=20;issue=2;spage=143;epage=146;aulast=Gupta http://www.ijri.org/article.asp?issn=0971-3026;year=2010;volume=20;issue=2;spage=143;epage=146;aulast=Gupta202 143 146 http://www.ijri.org/article.asp?issn=0971-3026;year=2010;volume=20;issue=2;spage=143;epage=146;aulast=Gupta P Gupta, S Kumar, Raju Sharma, A Gadodia

Cloacal dysgenesis sequence (CDS) is a lethal malformation with a highly variable presentation. CDS is characterized by direct communication between the gastrointestinal, urinary, and genital structures, resulting in a single perineal opening. Prenatal diagnosis of a cloacal anomaly is often difficult because of the highly variable imaging features. Here, we report a case in which a diagnosis of CDS was made with fetal MRI on the basis of a meconium-containing, bilobed, abdominopelvic cystic mass communicating with the ureters and the colon.]]> http://www.ijri.org/article.asp?issn=0971-3026;year=2010;volume=20;issue=2;spage=143;epage=146;aulast=Gupta Jaywant Wale Pankaj K Yadav Shairy Garg Multi-System Indian Journal of Radiology and Imaging 2010 20(2):147-149doi:10.4103/0971-3026.63056 Indian Journal of Radiology and Imaging 10.4103/0971-3026.63056 http://www.ijri.org/article.asp?issn=0971-3026;year=2010;volume=20;issue=2;spage=147;epage=149;aulast=Wale http://www.ijri.org/article.asp?issn=0971-3026;year=2010;volume=20;issue=2;spage=147;epage=149;aulast=Wale202 147 149 http://www.ijri.org/article.asp?issn=0971-3026;year=2010;volume=20;issue=2;spage=147;epage=149;aulast=Wale Jaywant Wale, Pankaj K Yadav, Shairy Garg

Elemental mercury poisoning most commonly occurs through vapor inhalation as mercury is well absorbed through the lungs. Administering subcutaneous and intravenous elemental mercury is very uncommon but with only a few isolated case reports in the literature. We present an unusual case of elemental mercury poisoning in a 20-year-old young male who presented with chest pain, fever, and hemoptysis. He had injected himself subcutaneously with elemental mercury obtained from a sphygmomanometer. The typical radiographic findings in the chest, forearm, and abdomen are discussed, with a review of the literature.]]> http://www.ijri.org/article.asp?issn=0971-3026;year=2010;volume=20;issue=2;spage=147;epage=149;aulast=Wale Manisha Jana Shivanand Ramachandra Gamanagatti Atin Kumar Multi-System Indian Journal of Radiology and Imaging 2010 20(2):150-153doi:10.4103/0971-3026.63037 Indian Journal of Radiology and Imaging 10.4103/0971-3026.63037 http://www.ijri.org/article.asp?issn=0971-3026;year=2010;volume=20;issue=2;spage=150;epage=153;aulast=Jana http://www.ijri.org/article.asp?issn=0971-3026;year=2010;volume=20;issue=2;spage=150;epage=153;aulast=Jana202 150 153 http://www.ijri.org/article.asp?issn=0971-3026;year=2010;volume=20;issue=2;spage=150;epage=153;aulast=Jana Manisha Jana, Shivanand Ramachandra Gamanagatti, Atin Kumar

Imaging a patient having a cardiac arrest on the examination table is not a common occurrence. Altered hemodynamics resulting from pump failure causes stasis of blood in the dependent organs of the body, which is manifested on imaging by dependent contrast pooling and layering. Often a patient with imminent cardiogenic shock also shows a similar dependent contrast pooling and layering, which is a marker of the worsening clinical condition. We report the contrast-enhanced CT scan features in four cases, two of whom had cardiac arrest during imaging, while the other two developed cardiogenic shock soon after the examination. Dependent contrast pooling and layering were found in all of them, with faint or no opacification of the left cardiac chambers. Contrast pooling was noted in the dependent lumbar veins, hepatic veins, hepatic parenchyma, and the right renal vein, as well as in the dependent part of the IVC and the right heart chambers.]]> http://www.ijri.org/article.asp?issn=0971-3026;year=2010;volume=20;issue=2;spage=150;epage=153;aulast=Jana Roshan S Livingstone Joe Pradip Paul M Dinakran B Srikanth Radiation Indian Journal of Radiology and Imaging 2010 20(2):154-157doi:10.4103/0971-3026.63036 Indian Journal of Radiology and Imaging 10.4103/0971-3026.63036 http://www.ijri.org/article.asp?issn=0971-3026;year=2010;volume=20;issue=2;spage=154;epage=157;aulast=Livingstone http://www.ijri.org/article.asp?issn=0971-3026;year=2010;volume=20;issue=2;spage=154;epage=157;aulast=Livingstone202 154 157 http://www.ijri.org/article.asp?issn=0971-3026;year=2010;volume=20;issue=2;spage=154;epage=157;aulast=Livingstone Roshan S Livingstone, Joe Pradip, Paul M Dinakran, B Srikanth

Objective: To evaluate the radiation dose and image quality using a manual protocol and dose modulation techniques in a 6-slice CT scanner. Materials and Methods: Two hundred and twenty-one patients who underwent contrast-enhanced CT of the chest were included in the study. For the manual protocol settings, constant tube potential (kV) and tube current-time product (mAs) of 140 kV and 120 mAs, respectively, were used. The angular and z-axis dose modulation techniques utilized a constant tube potential of 140 kV; mAs values were automatically selected by the machine. Effective doses were calculated using dose-length product (DLP) values and the image quality was assessed using the signal-to-noise (SNR) ratio values. Results: Mean effective doses using manual protocol for patients of weights 40-60 kg, 61-80 kg, and 81 kg and above were 8.58 mSv, 8.54 mSv, and 9.07 mSv, respectively. Mean effective doses using z-axis dose modulation for patients of weights 40-60 kg, 61-80 kg, and 81 kg and above were 4.95 mSv, 6.87 mSv, and 10.24 mSv, respectively. The SNR at the region of the liver for patients of body weight of 40-60 kg was 5.1 H, 6.2 H, and 8.8 H for manual, angular, and z-axis dose modulation, respectively. Conclusion: Dose reduction of up to 15% was achieved using angular dose modulation and of up to 42% using z-axis dose modulation, with acceptable diagnostic image quality compared to the manual protocol.]]> http://www.ijri.org/article.asp?issn=0971-3026;year=2010;volume=20;issue=2;spage=154;epage=157;aulast=Livingstone IK Indrajit Web Review Indian Journal of Radiology and Imaging 2010 20(2):158-159Indian Journal of Radiology and Imaging http://www.ijri.org/article.asp?issn=0971-3026;year=2010;volume=20;issue=2;spage=158;epage=159;aulast=Indrajit http://www.ijri.org/article.asp?issn=0971-3026;year=2010;volume=20;issue=2;spage=158;epage=159;aulast=Indrajit202 158 159 http://www.ijri.org/article.asp?issn=0971-3026;year=2010;volume=20;issue=2;spage=158;epage=159;aulast=Indrajit IK Indrajit
