Despite a consensus regarding the essential protocol components of a rectal cancer MRI, substantial differences in image quality persist across institutions and vendor software/hardware platforms. In this review, we present image optimization strategies for rectal cancer MRI examinations, including but not...
Restaging rectal MRI protocol Given the critical role of MRI in the staging and treatment response assessment of rectal cancer, the Society of Abdominal Radiology (SAR) Colorectal and Anal Cancer Disease-Focused Panel (DFP) have published recommendations for standardizing rectal MRI protocols.23 The ...
Rectal cancer (RC) represents approximately 30% of all CRC. In the last two decades, new multimodality strategies have reduced the local recurrence (LR) rate and extended the duration of overall survival (OS). The mainstay of treatment remains surgery; however, downsizing the tumor by neoadjuvan...
NCCN recommends MRI pelvis unless contraindicated. However, currently, there is significant variability in the quality of the rectal MRIs performed for rectal cancer. We recommend patients and payers seek out imaging centers that perform a dedicated rectal cancer protocol that meets recommended criteria ...
To enable the evaluation of locoregional disease in the on-going RECTOPET (REctal Cancer Trial on PET/MRI/CT) study; a methodology to match mesorectal imaging findings to histopathology is presented, along with initial observations. FDG-PET/MRI examinati
? 2023 Elsevier Inc.MR-guided radiotherapy is a treatment approach that combines the advantages of magnetic resonance imaging (MRI) with the precision of radiation therapy. This practical review provides an overview of the current state-of-the-art of MR-guided radiotherapy for rectal cancer, includ...
Magnetic resonance imaging (MRI) has established itself as the primary method for local staging in patients with rectal cancer. This is due to several factors, most importantly because of the ability to assess the status of circumferential resection margin. There are several newer developments being...

Imaging in rectal cancer has a vital role in staging disease, and in selecting and optimizing treatment planning. High-resolution MRI (HR-MRI) is the recommended method of first choice for local staging of rectal cancer for both primary staging and for restaging after preoperative chemoradiation (...
Patients with stage I-III rectal cancer typically undergo chemoradiation before surgery, but MRI can identify those who could skip this step and go straight to upfront surgery.
