PURPOSE: Torsion of the @entity1062 is a urologic emergency that requires early diagnosis and prompt surgical treatment for testicular survival. However, the early differential diagnosis of acute @entity4115 from @entity3892 or @entity11570 is often difficult. The aim of this retrospective study was to evaluate and compare the value of Tc-99m pertechnetate radionuclide imaging and ultrasonography in the differentiation of acute @entity4115 and inflammatory @entity10523 . METHODS: Twenty @entity1 (age range, 5 to 38 years) with possible acute @entity4115 from July 2000 to July 2001 were enrolled in this study. Ultrasonography was performed in all @entity1 in the emergency room. Within 3 hours of ultrasonography, radionuclide imaging was also performed after intravenous injection of 5 to 15 mCi Tc-99m pertechnetate in the forearms. All of the @entity1 with clinically suspected acute @entity4115 underwent surgery. The surgical findings and pathologic reports of these @entity1 were reviewed and definite diagnoses were established. None of the other @entity1 had surgery and were followed clinically for at least 1 month after ultrasonography and radionuclide imaging. RESULTS: Four @entity1 with @entity4115 , 13 @entity1 with inflammatory @entity10523 , and three healthy @entity1 had a final surgical and pathologic diagnosis or clinical follow-up, and all were accurately diagnosed by Tc-99m pertechnetate radionuclide imaging. In contrast, ultrasonography was less accurate in the diagnosis and differentiation of acute @entity4115 from @entity32 . Only 1 of 4 @entity1 with @entity4115 , 5 of 13 @entity1 with inflammatory @entity10523 , and 2 of 3 healthy @entity1 were diagnosed by ultrasonography. CONCLUSIONS: The results indicate that Tc-99m pertechnetate radionuclide imaging is a more useful and accurate imaging method than ultrasonography in the detection and differentiation of acute @entity4115 from inflammatory @entity10523 in @entity1 with @entity12761 .
