摘      要：Contrast-enhanced ultrasound(CEUS)is a new form of ultrasound(US)that can dynamically display microvessels in a highly sensitive *** purpose of this study was to investigate the efficacy of CEUS for characterizing testicular lesions in comparison with conventional ***-seven patients with testicular lesions were *** histopathology results revealed that 31 cases were neoplastic(11 cases of seminomas,8 nonseminomatous germ cell tumors,8 lymphomas,2 Leydig cell tumors,and 2 nonspecific tumors),and 16 cases were nonneoplastic(8 cases of infarctions,3 epidermoid cysts,and 5 inflammation).The indicators of shallow lobulated morphology and cystic-solid echogenicity on conventional US were suggestive of germ cell *** indicators on CEUS were found to be useful for characterizing testicular *** the neoplastic lesions showed hyperenhancement on ***,germ cell tumors presented with heterogeneous enhancement(73.7%,14/19),a twisted blood vessel pattern,rapid wash-in and wash-out,and peripheral rim hyperenhancement *** was characterized by nonbranching linear vessel patterns(87.5%,7/8),rapid wash-in and slow *** nonneoplastic lesions,infarction and epidermoid cysts showed no enhancement,and abscesses were observed with marginal irregular *** sensitivity,specificity,and accuracy of CEUS for differentiating between neoplastic and nonneoplastic lesions were 100%,93.8%,and 97.9%,respectively,and these values were higher than those for conventional US(90.3%,62.5%,and 80.9%,respectively).CEUS can sensitively reflect the microvascular perfusion in testicular lesions and offers high accuracy for characterizing them.
