Vessel tortuosity causing false positives in detecting renal artery stenosis on Doppler ultrasound.

abstract：:Ultrasound plays an important role in the diagnostic workup of scrotal diseases. It can differentiate a testicular mass from an extratesticular mass and determine whether the mass is cystic, solid, or complex. Using this information a likely diagnosis can be ascertained. In the acute scrotum, acute epididymitis/epidid...
