CHARACTERIZATION OF RENAL MASSES Many renal cell carcinomas (RCCs) are detected incidentally on imaging. Certain definite benign lesions on CT for which additional imaging is not necessary: On contrast CT: Homogeneous lesions with density less than 20 HU are benign On non-contrast CT: Homogeneous lesions with density less than 20 HU, or lesions with density …

Modalities used for prostate imaging are: Abdominal and transrectal Ultrasound MRI Nuclear Imaging Ultrasonography has a poorer sensitivity and specificity for detecting and characterizing cancer, and is a better modality for guided biopsy. Multiparametric MRI prostate is now the standard of care for imaging the prostate and detecting clinically significant cancer (American and European guidelines). …
