Introduction: Medical ultrasound is used as a common diagnostic tool for the patients attending the Outpatient Department (OPD). This study was designed with an aim to determine the incidence of positive findings among the OPD patients advised for ultrasound scan. Methods: In this study, a group of 300 subjects between the ages of 12 and 80 years of age, examined for different types of complaints attending the OPD of Sher-E-Bangla Medical College Hospital, Barishal, Bangladesh from January 2017 to June 2018. Ultrasound brightness mode (B-mode) and color Doppler scanning were performed using Siemens NX3 and Samsung HS 70A ultrasound machines. Results: Mostly female patients (89.33%) attended the OPD and maximum proportion of them are pregnant (48.67%). In addition, patients attending the OPD are coming from the rural area (53.33%) more due to less access to health service at rural level. Depending on the ultrasound scanning findings different disease were diagnosed, which includes incomplete abortion (6.00%), breast pathology (2.67%), polycystic ovarian disease (3.00%), enlarged prostate (1.00%), other pathologies e.g. fatty liver, PID, sebaceous cyst, enlarged thyroid, kidney cyst, cystitis, gallstone disease, biliary asca- riasis, ganglion cyst, foreign body in soft tissue, splenomegaly, hepatitis and others (16%). Conclusion: A number of patients (22.66%) attend OPD with complaints but they didn’t have any disease detectable by ultrasound scan. Most of these patients have huge bowel gas. Due to the availability, low-cost and non-invasive useful diagnostic procedure based on medical ultrasound became popular amongst the patients.
