Background & Method: The aim of this study is to study the role of high frequency ultrasound with colour Doppler in diagnosis of acute scrotal pain. Ultrasound of scrotum is performed with patient in supine position & the scrotum supported by towel placed between things. A large amount of gel is used to minimize pressure on the scrotal skin. High frequency linear array transducer is used for performing study. Each hemiscrotum is scanned in longitudinal & transverse planes.
