Histopathologically diagnose was considered as gold standard against which exactness / correctness of two diagnostic modalities were evaluated.

Results: 73.1% sensitivity, 75% specificity, 95% positive predictive value, 30% negative predictive value and 73.3% accuracy of Transabdominal ultrasonography for assessment of suspected ectopic pregnancy as a diagnostic modality, while as transvaginal ultrasonography 92.3%, 75%, 96%, 60% and 90% sensitivity, specificity, positive predictive value, negative predictive value and accuracy respectively.

Conclusion: Transvaginal was superior to Transabdominal ultrasonography for suspected ectopic pregnancy evaluation. Therefore, exact and early diagnosis of ectopic pregnancy, transvaginal ultrasonography is significant as well as important.
