Abstract
Summary: The role of dynamic radionuclide scanning of the testis has been assessed in 45 patients presenting with acute testicular pain or swelling. The technique is a simple, safe and rapid method for assessing testicular blood flow; the results correlate closely with the clinical course or the findings at surgical exploration. Decreased uptake is diagnostic of testicular ischaemia resulting from acute torsion of the spermatic cord. A resolved torsion may not be detected because the testis is no longer ischaemic and may actually show increased uptake due to reactive hyperaemia.
