Testicular torsion is a clinical diagnosis. If the history and physical examination strongly suggest testicular torsion, the patient should go directly to surgery without delaying to perform imaging studies.

When a low suspicion of testicular torsion exists, color Doppler and power Doppler ultrasonography can be used to demonstrate arterial blood flow to the testicle while providing information about scrotal anatomy and other testicular disorders. (For images, see Testicular Torsion Imaging.)

Plain Doppler ultrasonography is less accurate than color Doppler in assessing testicular blood flow. In fact, early in the course of testicular torsion, gray-scale ultrasonographic examination may be absolutely normal.
