MR Imaging of Scrotum
Magnetic resonance (MR) imaging of the scrotum has been used as a valuable supplemental diagnostic modality in evaluating scrotal pathology, mostly recommended in cases of inconclusive sonographic findings. Because of…
Magnetic Resonance Imaging of Penile Cancer
Penile cancer is a rare neoplasm that, although rare in the developed world, has devastating physical and psychological consequences for the patient. Novel MR imaging techniques such as lymphotropic nanoparticle-enhanced…
Magnetic Resonance Imaging in Rectal Cancer
MR imaging plays a key role in staging evaluation of rectal cancer. The cornerstone of staging MR involves high-resolution T2 imaging orthogonal to the rectal lumen. The goals of MR…
Diffusion-Weighted Imaging of the Male Pelvis
Diffusion-weighted (DW) imaging is playing an increasingly important role in disease detection, prognostication, and monitoring of treatment response. Particularly in the realm of oncology, the potential applications for DW imaging…
MR Imaging–Guided Prostate Biopsy Techniques
A diagnosis of localized prostate cancer has always represented a clinical challenge. Nearly all prostate biopsies are performed via the transrectal ultrasound (TRUS)-guided technique, which, however, suffers from multiple limitations…
MR Imaging of the Urinary Bladder
MR imaging is the modality of choice for accurate local staging of bladder cancer. In addition, bladder MR imaging helps detect lymph node involvement, and in conjunction with computed tomography,…
MR Imaging of Benign and Malignant Biliary Conditions
MR imaging is a noninvasive, radiation-free imaging method for evaluation of the biliary system. Continued advancements in MR imaging system hardware and sequence design, coupled with novel gadolinium chelate agents,…
Presurgical Planning for Hepatobiliary Malignancies
There are many considerations in the evaluation of liver malignancy before planned surgical treatment. This article focuses on interpretation of MR imaging of the liver for surgical treatment planning of…
Magnetic Resonance Elastography of Liver
Magnetic resonance elastography (MRE) assesses tissue stiffness in vivo by imaging propagating shear waves through the tissues and processing the wave information. MRE is a robust technology with excellent technical success;…
Perfusion Imaging in Liver MRI
Liver perfusion magnetic resonance (MR) imaging is currently being actively investigated as a functional imaging technique that provides physiologic information on the microcirculation and microenvironment of liver tumors and the…
