Sonography of acute scrotal abnormalities. 
Accurate diagnosis in patients with acute scrotal abnormalities remains a challenge to both radiologists and clinicians.  Sonography using either small parts scanners or conventional equipment available in almost all departments will continue to play a larger role in aiding the clinical assessment of these patients.  As a rapid, noninvasive imagining technique, sonography can reliably answer important clinical questions and guide prompt, early surgical or medical therapy.
