Acute Scrotum
Testicular artery supplies the testicle
low impedance flow (high diastolic pressures)
Cremasteric and deferential arteries supply the extra-testicular structures
high impedance flow (low diastolic flow)
use 7-10 mhz linear array
use frog leg posture with all but the testes covered
Two Questions
1. Is there intra-testicular flow
2. Is the echo texture of each testicle homogenous & organized or heterogeneous & disorganized (and is it the same as the other)
Visualize each testicle in transverse and longitudinal
Best to use spectral on both arterial and venous flow
when in transverse, you can see both testicles simultaneously
echogenicity normally looks like the liver
Normal flow will just consist of little dots
early torsion will have normal arterial flow and echogenicity, but venous flow will be absent.
late will have edema, so larger with increase echogenicity no flow in testicle at all
