Automatic segmentation of rectal tumor on diffusion-weighted images by deep learning with U-Net. [PDF]

J Appl Clin Med Phys, 2021
Purpose Manual delineation of a rectal tumor on a volumetric image is time‐consuming and subjective. Deep learning has been used to segment rectal tumors automatically on T2‐weighted images, but automatic segmentation on diffusion‐weighted imaging is ...

MRI interobserver reliability in rectal tumor angulation [PDF]

Acta Radiologica Open, 2022
Background When rectal tumors are examined using magnetic resonance imaging (MRI) the perpendicular angulation of the axial T2-weighted image to the tumor axis is essential for a correct measure of the shortest distance between tumor and mesorectal facia.

Management of rectal gastrointestinal stromal tumor [PDF]

Translational Gastroenterology and Hepatology, 2018
Gastrointestinal stromal tumor (GIST) is the most common mesenchymal neoplasm of the gastrointestinal tract. However, rectal GIST is rare, the incident rate of it is approximately 5% of all GISTs. Rectal GIST symptoms generally include bleeding and/or pain and occasionally, urinary symptoms.
