4. Figure 5: A 76-year-old male presented with a rubber band around his scrotum and scrotal swelling. (a) Transverse view of right testis demonstrates decreased blood flow on color Doppler. (b) Transverse view of left testis demonstrates near normal flow on color Doppler. (c) Abnormal spectral waveform with increased vascular resistance and no diastolic flow in the right testis. (d) Near normal spectral waveform in the left testis.
