Color-flow and power Doppler imaging of the testes

Abstract

The development of color-flow imaging has made ultrasound the primary imaging modality for the evaluation of testicular pathology. The ability to distinguish between epididymo-orchitis and torsion is of great clinical significance in those patients with acute onset of pain. Not only does the appropriate treatment depend on the correct diagnosis, but the outcome following that treatment is also dependent on establishment of the diagnosis. Although it is of less importance in the evaluation of testicular neoplasms, color-flow imaging does provide adjunctive information that can aid in establishment of the proper diagnosis in confusing clinical situations. The diagnosis of varicocele depends on color-flow imaging, and the prediction of testicular viability following trauma is essential for proper treatment. More studies concerning the use of power Doppler for imaging of scrotal disorders are necessary to determine what its role will be.
