Different sodium concentrations of noncancerous and cancerous prostate tissue seen on MRI using an external coil.
Radiol Adv
September 2024
Medical Biophysics, Western University, London, N6A 3K7, Canada.
Background: Sodium (Na) MRI of prostate cancer (PCa) is a novel but underdocumented technique conventionally acquired using an endorectal coil. These endorectal coils are associated with challenges (e.g.

Objective: To determine the diagnostic test accuracy of multiparametric magnetic resonance imaging (mpMRI) in detecting seminal vesicle invasion (SVI).
Methods: The Medical Literature Analysis and Retrieval System Online (MEDLINE), PubMed, the Excerpta Medica dataBASE (EMBASE) and Cochrane databases were search up to May 2023. We included studies that investigated the accuracy of mpMRI in detecting SVI when compared to radical prostatectomy specimens as the reference standard.

Purpose: To establish the incidence, size, zonal location and Gleason Score(GS)/Gleason Grade Group(GG) of sparse versus dense prostate cancer (PCa) lesions and to identify the imaging characteristics of sparse versus dense cancers on multiparametric MRI (mpMRI).
Methods: Seventy-six men with untreated PCa were scanned prior to prostatectomy with endorectal-coil 3 T MRI including T2-weighted imaging, diffusion-weighted imaging and dynamic contrast-enhanced MRI. Cancerous regions were outlined and graded on the whole-mount, processed specimens, with tissue compositions estimated.
What To Do With Suspected Nodal Regrowth on Magnetic Resonance Imaging During Follow-up in an Organ Preservation Approach for Rectal Cancer?
Dis Colon Rectum
September 2024
Department of Surgery, Netherlands Cancer Institute-Antoni van Leeuwenhoek, Amsterdam, The Netherlands.
Background: For nodal regrowth in patients with rectal cancer following watch-and-wait standardized protocols on diagnostic procedures and subsequent treatment are lacking.
Objective: Evaluate the diagnosis and treatment of suspected nodal regrowth following an organ preservation approach.
Settings: Patients were included from national and institutional watch-and-wait -databases.
