Gray Scale and Doppler Ultra-sound in the Diagnosis of Painless Scrotal Masses

Objective: To determine the role of gray scale and Doppler Ultrasound in the diagnosis of painless scrotal masses. Methodology: It was a descriptive study conducted at Department of radiology, Dow University of Health Science (DUHS) and Civil Hospital Karachi (CHK) from June 2006 to June 2007. Adult patients with painless scrotal mass referred for ultrasound examination, were included in the study. All subjects were scanned with 11 MHz linear transducer on NEMIO 17 scanner in supine position and erect posture as and when needed. Gray scale ultrasound was first conducted to determine the size, location and echogenecity of the lesion. Doppler ultrasound was done to assess and document the blood flow, spectrum, and velocity of flow and indices in the epididymis, as well as in the lesion. Accuracy of Doppler scan was determined against histopathology of the respected specimen in case of tumors and against surgical findings in the
