ABSTRACT: BACKGROUND: A common surgical emergency is acute appendicitis. Various diagnostic tools are available to diagnosis acute appendicitis. Radiological investigations play an important role in making accurate and early diagnosis and thus preventing morbidity associated with the disease. OBJECTIVE: To determine the diagnostic accuracy of gray scale ultrasonography versus color Doppler in suspected cases of acute appendicitis. MATERIALS AND METHODS: The study was carried in the department of Radiology of Mayo Hospital, Lahore. A total of 75 patients were enrolled of age 18-40 years, both genders who were suspected cases of acute appendicitis. All patients underwent baseline investigations along with gray scale ultrasonography and color Doppler. All patients were subjected to surgery to confirm the diagnosis and findings were subjected to statistical analysis. RESULTS: The mean age of the patients was 23.25 ±10.55 and mean transverse diameter of appendix was 8.37 ±3.39. There were 62.7% males and 37.3%females. Findings of gray scale ultrasonography and color Doppler were then correlated with surgical findings to calculate the diagnostic accuracy of these modalities. The results revealed that gray scale ultrasonography sensitivity, specificity, positive predictive value, negative predictive value and accuracy was 92.7%, 94.32%, 95%, 91.4% and 93.3% respectively, whereas color Doppler had sensitivity, specificity, positive predictive value, negative predictive value and accuracy of 97.7%, 93.9%, 95.3%, 97% and 96% respectively. Diagnostic accuracy of both modalities together was 98.6%. CONCLUSION: Color Doppler has better diagnostic accuracy than gray scale ultrasonography for diagnosis of acute appendicitis and the combination of both modalities yields diagnostic accuracy that is similar to gold standard.

Purpose: To compare the capabilities and evaluate the effectiveness of gray-scale B-mode, Doppler mapping and contrast enhanced in the assessment of cystic renal lesions.Material and methods: Ultrasound examination (US) was performed in 61 patients with cystic kidney formations (category Bosniak ≥ II). Cysts of categories Bosniak ≥ III were histologically verified, rest (categories II–IIF) were under follow up. All patients underwent gray-scale ultrasound, color Doppler imaging and contrast enhanced (CEUS).Results: The efficiency of the B mode was: sensitivity 55.6 %; specificity 72.1 %; accuracy 62.3 %, in the CDI mode these indicators were 52.8; 80.1; 63.9 %, respectively. Contrast ultrasound significantly increased the capabilities of the method, and also made it possible to evaluate cystic formations according to the Bosniak criteria with indicators of the effectiveness of the method up to 100.0; 92.0; 96.7 %, respectively.Conclusions: CEUS demonstrated high informative value in the assessment of renal cystic formations in comparison with native ultrasound and Doppler modes, and therefore the technique should be considered as promising for inclusion in the algorithm of examination of complex renal cysts.
