Role of Testicular Scintigraphy in the Assessment of Viability of Undescended Testis: Potential Pitfalls and Complementary Role of 18F FDG PET/CT.

ABSTRACT

ABSTRACT Doppler ultrasonography and testicular scintigraphy are sensitive techniques to detect the adequacy of blood flow to testicular tissue. Because Doppler ultrasonography is an operator-dependent imaging modality, it can result in equivocal findings. Testicular scintigraphy proves to be more accurate in such cases, but it may be inconclusive on occasion. The authors report the case of a young man with a left undescended testis where testicular scintigraphy was inconclusive for viability and 18F-FDG PET/CT provided important diagnostic information.
