Comparative evaluation of ultrasonography and CT in patients with abdominal trauma: A prospective study
Kshitish Mallik, Sushma Vashisht, Sanjay Thakur, DN Srivastava
October-December 2000, 10(4):237-243
Objectives: To assess the relative role of US and CT in patients with abdominal trauma and to compare it with operative findings or clinical outcome and also to suggest guidelines for imaging and management protocols based on the above results. Materials and Methods: Thirty-three consecutive and positive patients of abdominal trauma were evaluated with both ultrasonography (US) and computed tomography (CT). Thirty-one of them had blunt abdominal trauma. One patient had penetrating injury and another patient had blast trauma. Injuries to different organs were staged using organ injury scaling (OIS) system. Hemoperitoneum as detected on US and CT was scored. The US and CT findings were compared and correlated with the operative findings or clinical follow-up in conservatively managed cases Results: Patients with large hemoperitoneum required surgery more often. Grading of organ injuries did not correlate with need for surgery except for splenic injuries. In 25 patients, either US or CT would have been sufficient for arriving at a management decision. In seven patients, CT altered the management decision that was arrived at on the basis of US. One patient required angiography for diagnosis and vascular intervention. Conclusions: CT is better than US for the diagnosis of abdominal trauma. However US can be used as a useful initial modality. It is important that in all patients where US indicated presence of abnormality, in suboptimal US studies and in US-negative studies in symptomatic patients, the studies be supplemented with CT. Truly normal US scans in asymptomatic patients may be highly reliable for excluding significant organ injuries and these patients may be followed up without CT scan or admission.

Quantitative ultrasound as a tool for assessment of bone status: An initial experience
Anand L Parihar, Vandana M Dialani, Anant S Mashankar, Parag S Salkade, Manoj S Varma
October-December 2000, 10(4):229-231
Objectives: To determine the incidence of osteopenia and osteoporosis in the general population using broadband ultrasound bone densitometer. Material and Methods: Heel bone mineral densitometry was performed in 1713 patients with the help of a broadband ultrasond bone densitometer. The broadband ultrasound attenuation (BUA) and ultrasonic speed of sound (SOS) of the calcaneus were measured to obtain quantitative ultrasound index (QUI), bone mineral density (BMD), T-score and Z-score. Fracture risk was also estimated. Results: Out of the 1713 patients, 685 (39.9%) were found to have osteopenia and 190 (11%) had osteoporosis. The incidence of osteopenia and osteoporosis in women (41.6% and 14.2% respectively) was found to be higher than the values in men (37.1% and 5.5 % respectively). The incidence of osteopenia in the 31-39 years age group was found to be comparable in men and women (30.1% and 26.4% respectively). However, after the age of 40, the incidence of osteopenia and osteoporosis in women rose rapidly and was higher than that in men. Discussion: Bone formation is at it's peak in the mid 20's and continues till the age of 30-35 years after which the bone resorption gradually becomes faster than the formation of new bone. Bone density at any age would depend on peak bone density and the subsequent rate of bone loss. It is therefore important to determine the BMD in this age group to prevent osteoporosis and related complications later. Similarly it is important to subject women to assessment of BMD routinely after the age of 40 years as they are definitely at a higher risk of developing osteoporosis with advancing age.

Evaluation of skin lesions with color doppler and spectral analysis
Ravi Pushkarna, Satish K Bhargava, MC Baruah, Sandip Mohanty, Nirupama Pushkarna
October-December 2000, 10(4):233-236
Objectives : Skin lesions in twenty-four patients were evaluated with the help of color Doppler and spectral analysis in an effort to characterize the ultrasonographic differentiating features of various benign and malignant lesions. Material and Methods : A 7.5 MHz linear array small parts probe was used on a Philips P700 scanner, a real time scanner with color Doppler facility. Twenty-four patients with skin lesions were evaluated with gray scale US, duplex and color flow Doppler US. The patients were referred from our dermatology department without a clinical diagnosis. The age of the patients ranged from 15-65 years. Gray scale US findings of the lesions were obtained and compared with the normal skin on the contralateral region of the body. The lesions were evaluated for vascularity with color flow Doppler imaging. Maximum systolic and end diastolic velocities were measured and RI was calculated. The lesion was examined from two and more regions in order to minimize the error and average values of velocities were obtained. The Doppler settings used were (VFW) variable focal windowing in which depth was selected according to the size of the lesion and maximum (EE) edge enhancement for optimum visualization of the lesion. Results : Twenty-four patients were studied. Out of twenty-four patients seventeen patients showed benign lesions and seven patients showed malignant lesions. Seven patients out of twenty four patients showed color flow, four in benign lesions and three in malignant lesions. Seven patients out of twenty-four (30%) showed color flow pattern. Four out of seventeen benign lesions (24%) showed color flow pattern. Three out of seven malignant lesions (42%) showed color flow pattern. The thickness of the lesions was measured and ranged between 0.27-2.21 cm. The diameter of the lesions was between 0.67-3.40 cm. In our study we found that the thickness and diameter of the lesions did not play a significant role in the color flow patterns obtained. The RI values obtained were found to be overlapping in benign and malignant lesions. However the mean peak systolic velocities obtained from benign and malignant skin lesions were 5.75 cm/sec and 35.40 cm/sec per second respectively with a significant P-value =0.000 (t-test). There was a significant difference between the peak systolic velocities obtained between the benign and malignant lesions. The mean end diastolic velocities of benign and malignant lesions were 3.00 cm/sec and 15.67 cm/sec respectively. The P-value=0.005 (t-test) was also significant. Conclusions : The Majority of the skin tumors are benign and therefore there is a need for a non-invasive method that aids the selection of malignant tumors for their removal. Color Doppler US and spectral analysis of skin lesions are a useful compliment to skin biopsy for differentiating between benign and malignant skin lesions. Our study proves that the flow velocities of skin lesion are very significant in differentiating between benign and malignant skin lesions and also work as a supporting diagnostic tool in doubtful and challenging cases. However excision biopsy is the gold standard for analysis of such lesions.
