Radiomics in Kidney Cancer
Renal tumors encompass a heterogeneous disease spectrum, which confounds patient management and treatment. Percutaneous biopsy is limited by an inability to sample every part of the tumor. Radiomics may provide…
Future Perspectives in Multiparametric Prostate MR Imaging
Multiparametric MR imaging is being used for prostate cancer diagnosis. However, many cancers are missed and the performance needs to improve before it can be used for population-level screening. We…
MR Imaging of the Penis and Urethra
MR imaging has been increasingly used as a problem-solving adjunct after an initial ultrasound examination for a variety of penile disorders, and is the best cross-sectional imaging modality for the…
MR Imaging of the Urinary Bladder
Key points • MR imaging has been reported to be particularly successful in the differentiation of Ta-T1 tumors from T2 and higher staged tumors with 90% sensitivity and 88% specificity…
MR Imaging–Guided Focal Therapies of Prostate Cancer
MR imaging-guided focal therapy is a viable treatment option for patients with localized prostate cancer. After the identification of a malignant focus in the prostate gland on multiparametric MR imaging,…
Infectious and Inflammatory Diseases of the Urinary Tract
Urinary tract infection (UTI) is among the most common of bacterial infections. Imaging studies are only required in cases of complicated UTIs. Ultrasound remains the first-line imaging method; however, CT…
Magnetic Resonance Imaging of the Perirenal Space and Retroperitoneum
Retroperitoneal diseases are frequently a great clinical challenge because of their nonspecific presentation. Diseases may be asymptomatic with indolent biological behavior, and often show a large mass at initial imaging…
MR Imaging Evaluation of the Kidneys in Patients with Reduced Kidney Function
MR imaging has been optimized for the evaluation of a multitude of disease processes affecting the kidneys. A wide variety of noncontrast methods are available for the evaluation of both…
Classification and Diagnosis of Cystic Renal Tumors
Superior soft tissue and contrast resolution of MR imaging benefits sensitivity to kidney cyst features and classification, which may have an impact on patient management and outcomes. Contrast-enhanced ultrasound (CEUS)…
MR Imaging Evaluation of Pediatric Genital Disorders:
MR imaging is frequently used to assess pediatric genital disorders. The ability to obtain 3-dimensional sequences allowing for multiplanar reformations and sequences designed to minimize motion artifact have aided in…
