Using a single-blind study design, nine adult male dogs underwent intravaginal spermatic cord torsion and subsequent evaluation with technetium 99M-pertechnetate radionuclide, and color doppler ultrasound imaging techniques. Torsions of 90 to 720 degrees were created surgically, followed by examination with each modality at one hour (four animals), and four hours (five animals) following the procedure. Testicular torsion was diagnosed if perfusion was absent or markedly diminished on color doppler imaging or radionuclide scan. In all cases of 360 degrees or greater, torsion was diagnosed by either modality at both one and four hour time delays. If observers did not diagnose torsion, they were asked to assess the relative testicular perfusion. Color doppler ultrasound and radionuclide scanning were without error in correctly detecting a relative decrease in perfusion in each of these instances. Furthermore, color doppler imaging with spectral analysis was able to detect an enhancement of the diastolic component of the arterial signal at 180 degrees of torsion. This spectral pattern coupled with a relative decrease in blood flow allowed presumptive diagnosis at one hour of partial torsion that was subsequently apparent as absent perfusion only after 4 hours on radionuclide and repeat color doppler ultrasound. Color doppler ultrasound proved to be superior to radionuclide scanning in detecting diminished perfusion in this experiment. The detailed information provided by spectral and anatomic display with color doppler ultrasound recommends it for the evaluation of acute scrotal pathology of uncertain etiology. © 1991 by The American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetailsCited ByKalfa N, Veyrac C, Lopez M, Lopez C, Maurel A, Kaselas C, Sibai S, Arena F, Vaos G, Bréaud J, Merrot T, Kalfa D, Khochman I, Mironescu A, Minaev S, Avérous M and Galifer R (2018) Multicenter Assessment of Ultrasound of the Spermatic Cord in Children With Acute ScrotumJournal of Urology, VOL. 177, NO. 1, (297-301), Online publication date: 1-Jan-2007.SESSIONS A, RABINOWITZ R, HULBERT W, GOLDSTEIN M and MEVORACH R (2018) Testicular Torsion: Direction, Degree, Duration and DisinformationJournal of Urology, VOL. 169, NO. 2, (663-665), Online publication date: 1-Feb-2003.Allen T and Elder J (2018) Shortcomings of Color Doppler Sonography in Diagnosis of Testicular TorsionJournal of Urology, VOL. 154, NO. 4, (1508-1510), Online publication date: 1-Oct-1995.Costabile R, Choyke P, Frank J, Girton M, Diggs R, Billups K and Desjardins C (2018) Variability of Ischemia during Spermatic Cord Torsion in the RatJournal of Urology, VOL. 151, NO. 4, (1070-1072), Online publication date: 1-Apr-1994.Steinhardt G, Boyarsky S and Mackey R (2018) Testicular Torsion: Pitfalls of Color Doppler SonographyJournal of Urology, VOL. 150, NO. 2 Part 1, (461-462), Online publication date: 1-Aug-1993.Kass E, Stone K, Cacciarelli A and Mitchell B (2018) Do all Children with an Acute Scrotum Require Exploration?Journal of Urology, VOL. 150, NO. 2 Part 2, (667-669), Online publication date: 1-Aug-1993.Costabile R, Choyke P, Frank J, Girton M, Diggs R, Billups K, Moonen C and Desjardins C (2018) Dynamic Enhanced Magnetic Resonance Imaging of Testicular Perfusion in the RatJournal of Urology, VOL. 149, NO. 5 Part 1, (1195-1197), Online publication date: 1-May-1993.Wilbert D, Schaerfe C, Stern W, Strohmaier W and Bichler K (2018) Evaluation of the Acute Scrotum by Color-Coded Doppler UltrasonographyJournal of Urology, VOL. 149, NO. 6, (1475-1477), Online publication date: 1-Jun-1993.
