The relative attenuation of solid renal lesions and normal renal cortex was determined in the unenhanced and nephrographic phase. Statistical comparison was carried out by Mann‐Withney test.ResultsThe oncocytomas and cc‐RCC average size was 3.7cm [1.8 to 14] and 3.5cm [1.9 to 8.4], respectively. The average attenuation in the unenhanced phase was 33HU and 32HU, respectively. In nephrographic phase, the average contrast enhancement was 47.5 and 47.4H, respectively. In nephrographic phase, the attenuation difference between the oncocytomas and normal renal cortex was 43.5HU and the attenuation difference between the cc‐RCC and normal renal cortex was 59.7HU. These results were statistically significant (p<0.05).ConclusionsIn the nephrographic phase, URO‐CT reveals that oncocytomas have greater isodensity to the normal renal cortex compared to cc‐RCC. This finding can help us to determine which lesions we should biopsy or not.","PeriodicalId":100020,"journal":{"name":"Acta Urológica Portuguesa","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88178792","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, it was intended to evaluate the usefulness of 18F‐Fluorocoline positron emission tomography/computed tomography (18F‐FCH‐PET/CT) in the workup of patients with the initial diagnosis of prostate cancer and staged by this imaging technique.Material and methodsThe medical records of 39 patients with prostate cancer who underwent 18F‐FCH PET/CT for initial staging, between November 2010 and April 2015, were reviewed. Of these, 20 patients were excluded because they had already started hormonotherapy. In the other 19 patients, the performance of 18F‐FCH PET/CT for the detection of lymph node metastasis was evaluated by calculating the sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy. Six patients had performed pelvic lymphadenectomy (total of 69 lymph nodes), allowing histological confirmation. When there was no histological confirmation (total of 30 lymph nodes and 3 cases of bone metastasis), the findings of 18F‐FCH PET/CT were correlated with the values of PSA and the information from multiple imaging modalities such as CT, bone scan, magnetic resonance (MRI), 18F‐Sodium Fluoride (18F‐NaF) PET/CT of control.ResultsThe sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy for lymph node metastasis detection were, respectively, 96.8%, 80.9%, 69.8%, 98.2% and 85.8%.
