Radiology reports were evaluated to determine the noun representing the mass, the modifier to convey the likelihood of cancer, and recommendations for urologic referral. Electronic medical records were reviewed to determine if the patient saw a urologist.ResultsOf the patients, 112 (60%) had a class III mass and 74 (40%) had a class IV mass. Class III masses were more likely to be represented by the noun \"lesion\" rather than a \"mass\" (61/112 [54%] vs. 31/112 [28%]). Class IV masses are more likely to be represented as a \"mass\" (36/74 [59%] vs. 28/74 [38%]; P < 0.015). Cancer was described in 100/186 (54%) cases: 38/112 (35%) class III masses and 62/74 (72%) class IV masses (P < 0.001). The cancer terminology used included \"renal cell carcinoma\" (n = 57), \"neoplasm\" (n = 12), and \"malignancy/malignant\" (n = 86). Most radiology reports (n = 133, 72%) did not recommend urologic referral but 183 (98%) patients were referred and 181 (97%) ultimately saw a urologist.ConclusionRadiologists vary in their communication of class III and IV masses, reflecting historical terminology usage, nuanced interpretations, and an evolving understanding of renal cell carcinoma biology.

Cumulative effective dose (CED) was estimated per patient by diagnosis.

We observed slight hyperintensity of the left PC&A in older adults and probable AD (pAD) patients on T2-weighted fluid-attenuated inversion recovery (T2W-FLAIR) images.PurposeTo quantitatively assess the validity of the left PC&A hyperintensity in older adults and pAD patients.Material and MethodsT2W-FLAIR images from three groups were retrospectively evaluated: (i) younger control (YC; n = 77): individuals aged 37.9 ± 8.4 years; (ii) older control (OC; n = 98): individuals aged 76.9 ± 5.3 years without cognitive impairment; and (iii) pAD (n = 35): individuals aged 80.5 ± 6.9 years with pAD. Signal intensity (SI) ratios of the left to right PC&A (L-PC&A/R-PC&A) were calculated for all groups. In the OC and pAD groups, SI ratios of the left PC&A to pons (L-PC&A/P) and the right PC&A to pons (R-PC&A/P) were calculated. The regions of interest were defined as large as possible on transaxial images in which the PC&As were most broadly depicted.ResultsThe mean L-PC&A/R-PC&A in the YC, OC, and pAD groups showed an increasing trend in that sequence (P < 0.001). The mean L-PC&A/P was higher in the pAD group than in the OC group (P < 0.001). However, the mean R-PC&A/P was not significantly different between the OC and pAD groups (P = 0.245).ConclusionThe SI of the left PC&A on T2W-FLAIR images significantly increased with age and in individuals with pAD, likely reflecting the deterioration of the left PC&A.","PeriodicalId":7143,"journal":{"name":"Acta radiologica","volume":" ","pages":"2841851251328261"},"PeriodicalIF":1.1,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143690845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
