| PURPOSE : To Compare color Doppler ultrasonography(US) and power Doppler US in the detection of intratesticu-lar
blood flow in normal infants and to asses the symmetry of blood flow.
MATERIALS and METHODS : Testicular blood flow was assesed prospectively in 100 testes of 50 infants with both pow-er
and color Doppler US. We compared the power Doppler with color Doppler to detect intratesticular blood.
When the flow was detected, intratesticular blood flow was graded as follows : grade 1 : single intratesticular
Doppler signal; grade 2 : multiple intratesticular Doppler signals. The symmetry of intratesticular flow was ass-esd
by using the same method.
RESULTS : Intratesticular flow was detected in 72 (72%) and 68 (68%) testes on power and color Doppler US, re-s
pectively. In 76 testes(76%), intratesticular flow was detected in either one or both techniques. On Power
Doppler US, grade 1 was seen in 40 testes and grade 2 in 32 testes. On color Doppler US, grade 1 was noted in
52 testes and grade 2 in 16 testes. Testicular blood flow was symmetric on both power and color Doppler US in
each patient.
CONCLUSION :There was no difference between power Doppler and color Doppler ultrasonography in detecting in-tratesticular
blood flow in normal infants. |
