The final pathology was benign in 156 patients (17%). After exclusions, 140 patients with 163 benign tumors were included and 3 sets of the CT interpretations by radiologists with varying levels of experience were analyzed. &lt;b&gt;&lt;i&gt;Results:&lt;\/i&gt;&lt;\/b&gt; The histological breakdown was as follows: oncocytomas (54.6%), angiomyolipomas (AMLs; 30.7%), renal cysts (8.0%), other miscellaneous benign tumors (6.7%). The sensitivities of diagnosing oncocytomas were 3.4, 9.0, and 13.5% in primary radiological reports, second blinded reviews, and third non-blinded reviews, respectively (&lt;i&gt;p&lt;\/i&gt; = 0.055). The sensitivities of diagnosing AMLs were 46.0, 58.0, and 62.0% in the 3-sets of CT interpretations, respectively (&lt;i&gt;p&lt;\/i&gt; = 0.246). As for renal cysts, the sensitivities were 69.2, 92.3, and 100% in the 3-sets of CT interpretations, respectively (&lt;i&gt;p&lt;\/i&gt; = 0.051). In primary reports, the positive predictive values were 95.8% in lipid poor (lp)-AMLs, 60.0% in oncocytomas, 69.2% in renal cysts, respectively (&lt;i&gt;p&lt;\/i&gt; &lt; 0.05). &lt;b&gt;&lt;i&gt;Conclusions:&lt;\/i&gt;&lt;\/b&gt; Current conventional CT imaging still has limitations in differentiating oncocytomas and lp-AMLs from renal cell carcinomas, even when images were re-examined by experienced radiologists.<\/jats:p>","DOI":"10.1159\/000460303","type":"journal-article","created":{"date-parts":[[2017,3,7]],"date-time":"2017-03-07T22:01:28Z","timestamp":1488924088000},"page":"229-236","source":"Crossref","is-referenced-by-count":12,"title":["Does Computed Tomography Still Have Limitations to Distinguish Benign from Malignant Renal Tumors for Radiologists?"],"prefix":"10.1159","volume":"99","author":[{"given":"Toshitaka","family":"Shin","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vinay A.","family":"Duddalwar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Osamu","family":"Ukimura","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Toru","family":"Matsugasumi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Frank","family":"Chen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nariman","family":"Ahmadi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andre Luis","family":"de Castro Abreu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiromitsu","family":"Mimata","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Inderbir S.","family":"Gill","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2017,3,8]]},"container-title":["Urologia Internationalis"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/460303","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/460303","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/460303","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T17:14:49Z","timestamp":1745428489000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000460303"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017]]},"references-count":0,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2017,9,5]]}},"URL":"https:\/\/doi.org\/10.1159\/000460303","archive":["Portico"],"relation":{},"ISSN":["0042-1138","1423-0399"],"issn-type":[{"value":"0042-1138","type":"print"},{"value":"1423-0399","type":"electronic"}],"subject":[],"published":{"date-parts":[[2017]]}}}
