Abstract :
This cross sectional study was carried out in the department of Radiology and Imaging, Dhaka Medical College Hospital from July 2008 to June 2010 to compare the accuracy of transvaginal ultrasonography and transabdominal ultrasonography in the diagnosis of clinically suspected cases of ectopic pregnancy. Initially 60 patients with clinical suspicion of ectopic pregnancy were included in this study after analyzing selection criteria 30 patients underwent both transvaginal and transabdominal ultrasonography. ‘Histopathological diagnosis’ was considered gold standard against which accuracies of two diagnostic modalities were compared. Sensitivity, specificity, positive predictive value, negative predictive value and accuracy of transabdominal ultrasonography as a diagnostic modality in evaluation of suspected ectopic pregnancy were 73.1%, 75%, 95%, 30% and 73.3% respectively where as transvaginal ultrasonography was found to have 92.3% sensitivity, 75% specificity, 96% positive predictive value, 60% negative predictive value and 90% accuracy. Transvaginal ultrasonography wassuperior to transabdominal ultrasonography in the evaluation of suspected ectopic pregnancies .so, transvaginal ultrasonography is important for early and accurate diagnosis of ectopic pregnancy.
