OBSTETRIC IMAGING
Role of color doppler in pregnancy induced hypertension (a study of 100 cases)
CJ Bhatt, J Arora, MS Shah
October-December 2003, 13(4):417-420
Objective: To evaluate the role of Color Doppler in predicting the fetal outcome in cases of pregnancy induced hypertension (PIH). Materials & Methods: A total of 100 cases of PIH between 28 - 36 wks of gestation were studied over a period of 2 years. A color doppler scanner with a 3 - 5 MHz curvilinear probe was used for studying uterine, umbilical & fetal middle cerebral arteries. We used only S/D ratio as the indicator to evaluate perinatal outcome. The results of first doppler examination were taken into consideration for the study. Follow up study was done whenever required. S/D ratio of more than 3 in umbilical artery & more than 2.6 in uterine artery was considered abnormal. The results were correlated with parameters of fetal outcome. Results: In our study of 100 hypertensive cases 56% had abnormal S/D ratio in umbilical artery and/or uterine artery. 60% of these patients delivered IUGR babies. In patients with absent end diastolic velocity (AEDV) & reversed end diastolic velocity (REDV) perinatal mortality was 50% & 50% had IUGR babies. The fetuses with compromised circulation showed increased diastolic flow in fetal MCA suggestive of brain sparing effect. The results of abnormal umbilical artery were more significant than uterine artery in predicting perinatal outcome. The patients who had follow up studies, the improving S/D ratio suggested good fetal outcome whereas increasing S/D ratio showed poor fetal outcome. Conclusion: Color Doppler is an excellent tool for non-invasive hemodynamic monitoring of PIH patients. It helps to identify the fetuses at risk & predict perinatal morbidity & mortality. Doppler velocimetry can guide us in the treatment of these pregnancies & prevention of high mortality & morbidity in hypertensive patients

Diffusion weighted magnetic resonance imaging in acute ischemic stroke
C Kesavadas, M Fiorelli, AK Gupta, P Pantano, L Bozzao, TR Kapilamoorthy
October-December 2003, 13(4):433-440
Stroke is a leading cause of death and disability worldwide. With the advent of thrombolytic therapy in the treatment of acute stroke, it has become increasingly important to identify suitable patients for whom such therapy may be useful. Diffusion imaging has a high degree of sensitivity and specificity for diagnosing acute brain ischemia. The purpose of this article is to review the basis of diffusion weighted imaging (DWI), to consider its application in acute stroke and to recognize potential pitfalls and stroke mimics that might be encountered. Along with perfusion imaging. DWI helps in identifying the area of diffusion - perfusion mismatch representing the operational ischemic penumbra. Together with apparent diffusion coefficient (ADC) maps DWI images helps in distinguishing acute from subacute and chronic ischemic insults. The hyperintense area in DWI seen in acute brain ischemia can be reversed if early thrombolysis is instituted. In nearly half the patients with clinically defined transient ischaemic attack, DWI demonstrates ischaemic abnormality. The newer MR techniques developed for reducing susceptibility artifacts associated with diffusion imaging and the role of diffusion tensor imaging in the diagnosis of stroke have also been discussed in this review.

Imaging of cochlear implants
IK Indrajit, JD Souza, VK Singh, E James, S Badhwar
October-December 2003, 13(4):371-378
Traditionally, cochlear implants are restrictedly perceived by radiologists as devices absolutely contraindicated for MRI studies. With increasing cochlear implantations carried out world over, and the increasing availability of Digital Radiography and Multislice CT, imaging plays a key role, both in preoperative period and following implantation [1]. Essentially, cochlear implants are medical devices that electrically stimulate the auditory nerve in the cochlea. Designed to allow patients with severe hearing loss to perceive sound, cochlear implant systems contain internal electrode array that is placed inside the cochlea. Computed tomography (CT) is considered the modality of choice for accurate imaging of the bony labyrinth. Of late, Multislice CT applications not only accurately displays complex three-dimensional anatomic structures of inner ear and contents of middle ear cavity, but also generates interactively volume rendered images of labyrinth. This review article demystifies Cochlear Implants and illustratively describes the role of imaging generated by Digital Radiography and Multislice CT.

Anterior urethral diverticulum: Report of two cases
VD Trivedi, SA Salve, P Dangle, A Navale, S Merchant, M Farooq
October-December 2003, 13(4):441-442
Diverticulae of the male urethra are relatively rare entities and review of literature regarding their cause, classification, and management is multifaceted and controversial. Acquired anterior urethral diverticuli without adequate or intact corpus spongiosum and those with well-defined thick walls are best treated oy open surgical techniques. [1] A micturating cystourethrogram (MCU) and ultrasonography (USG) to determine the presence of surrounding tissue (corpus spongiosum) and the wall thickness plays a major role in determining the management. Thin walled and intact diverticula's can be treated by visual urethral urethrotome. [2]

Lateral ventricle craniopharyngioma - MRI demonstration of migratory nature of ectopic craniopharyngioma from the suprasellar region
J Singh, K Ganesan, SB Desai, A Kohli, E Kaushik
October-December 2003, 13(4):427-429
Ectopic craniopharyngiomas are located within the third ventricle, nasopharynx, sphenoid bone, cerebellopontine angle and pineal region. Some of these ectopic locations are explained by migration of the craniopharyngioma from the site of the craniopharyngeal duct from which these tumors arise. We report a case of a lateral ventricle craniopharyngioma with pre-operative imaging demonstration of this migratory nature of the tumor from the suprasellar region.

MR findings in trichobezoar
A Sharma, Saurabh , Samarjeet , N Sharma, UK Makwane
October-December 2003, 13(4):409-412
A 21-year-old female presented with gastric outlet obstruction and a palpable mass in epigastrium and clinical diagnosis of HCC was put forward. US findings were suggestive of band like echogenic structure with total posterior acoustic shadowing. CT findings were characteristic of trichobezoar. Single shot heavily T2 weighted image and BFE CORONAL images were comparable with barium meal projection. In present case we performed barium meal examination, as a last investigation. We have described MR findings and in literature we could trace only one case in which MR findings of trichobezoar with gastric ulcer has been described.

Mesenchymal tumors represent 1% to 2% of pancreatic neoplasms. These unusual tumors arise from the connective, vascular and neuronal tissue in pancreas. They are classified according to their main histological component. In selected instances, cross sectional imaging can offer a specific diagnosis of histological type [1]. In present case we documented imaging findings in leiomyosarcoma arising from the head of pancreas in 28-year- old patient
