The purpose of this study was to investigate the efficacy of CEUS for characterizing testicular lesions in comparison with conventional US. Forty-seven patients with testicular lesions were enrolled. The 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 tumors. More indicators on CEUS were found to be useful for characterizing testicular lesions. All the neoplastic lesions showed hyperenhancement on CEUS. Moreover, 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 signs. Lymphoma was characterized by nonbranching linear vessel patterns (87.5%, 7\/8), rapid wash-in and slow wash-out. In nonneoplastic lesions, infarction and epidermoid cysts showed no enhancement, and abscesses were observed with marginal irregular enhancement. The 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.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.4103\/aja202158","type":"journal-article","created":{"date-parts":[[2021,9,14]],"date-time":"2021-09-14T04:15:20Z","timestamp":1631592920000},"page":"201-206","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":17,"title":["Contrast-enhanced ultrasound as a valuable imaging modality for characterizing testicular lesions"],"prefix":"10.4103","volume":"24","author":[{"given":"Jie","family":"Yu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xin-Hui","family":"Jiang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lian-Fang","family":"Du","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Min","family":"Bai","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhao-Jun","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiu-Sheng","family":"Shi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qi","family":"Jiang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fan","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"R1-15-20240829","doi-asserted-by":"crossref","first-page":"2268","DOI":"10.1007\/s00330-015-4059-7","article-title":"Incidentally detected non-palpable testicular tumours in adults at scrotal ultrasound: impact of radiological findings on management Radiologic review and recommendations of the ESUR scrotal imaging subcommittee","volume":"26","author":"Rocher","year":"2016","journal-title":"Eur Radiol"},{"key":"R2-15-20240829","doi-asserted-by":"crossref","first-page":"272","DOI":"10.1097\/JU.0000000000000318","article-title":"Diagnosis and treatment of early stage testicular cancer: AUA Guideline","volume":"202","author":"Stephenson","year":"2019","journal-title":"J Urol"},{"key":"R3-15-20240829","doi-asserted-by":"crossref","first-page":"7","DOI":"10.3322\/caac.21551","article-title":"Cancer statistics, 2019","volume":"69","author":"Siegel","year":"2019","journal-title":"CA Cancer J Clin"},{"key":"R4-15-20240829","doi-asserted-by":"crossref","first-page":"251","DOI":"10.1016\/j.mcna.2017.10.003","article-title":"Testicular cancer: epidemiology, diagnosis, and management","volume":"102","author":"Smith","year":"2018","journal-title":"Med Clin North Am"},{"key":"R5-15-20240829","doi-asserted-by":"crossref","first-page":"635","DOI":"10.1016\/j.rcl.2019.01.007","article-title":"Scrotal ultrasound","volume":"57","author":"Rebik","year":"2019","journal-title":"Radiol Clin North Am"},{"key":"R6-15-20240829","doi-asserted-by":"crossref","first-page":"110","DOI":"10.11152\/mu.2013.2066.181.esy","article-title":"Contrast enhanced harmonic ultrasonography for the evaluation of acute scrotal pathology.
