European Radiology: Imaging assessment of extrarectal space lymph nodes for rectal cancer

Low-grade locally advanced rectal cancer (LARC) often presents with the spread of lymph nodes (LLNs) in the extrarectal space, including lymphoid tissue located on the side of the mesenteric membrane, which is not removed

We found that almost all lymph node imaging studies focused on the mesenteric lymph nodes

A recent study, published in the journal European Radiology, explored differences in diagnostic opinion among radiologists when measuring LLN short axis size, anatomical position, and determining whether LLN is suspicious, and assessed whether assisted specialized training could significantly improve the magnitude of

A total of 53 radiologists evaluated rectal MRI scans of three patients and filled out a questionnaire reporting the presence, location, size and suspiciousness of

Correct identification of anatomical locations improved in cases 1 (62% to 77% (p = .

This study found that while radiologists had a high rate of consensus on subjective judgments about the degree of malignancy of LLNs, there were differences
