Imaging Studies I: CT and MRI

229
Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Area of Science:

  • Medical Imaging
  • Artificial Intelligence in Medicine
  • Cardiovascular Imaging

Background:

  • Acute aortic dissection (AD) is a life-threatening condition requiring rapid diagnosis.
  • Current diagnostic workflows can be time-consuming, delaying critical interventions.
  • Automated detection of AD in computed tomography (CT) scans could enhance clinical efficiency.

Purpose of the Study:

  • To develop and validate a robust convolutional neural network (CNN)-based pipeline for real-time screening of abdominal AD in CT scans.
  • To create an automated system that assists healthcare professionals in identifying signs of abdominal AD.

Main Methods:

  • A retrospective study collected abdominal CT data from AD and non-AD patients.
  • A CNN algorithm was trained to detect abdominal AD, involving aorta region isolation and membrane highlighting.
  • The pipeline was validated on internal and external datasets using metrics like AUC and balanced accuracy.

Main Results:

  • The CNN pipeline achieved high performance across datasets.
  • Internal dataset: AUC 0.932, balanced accuracy 0.860, sensitivity 0.885.
  • External validation dataset: AUC 0.993, balanced accuracy 0.933, sensitivity 1.000.

Conclusions:

  • The developed automated pipeline demonstrates significant potential for assisting in the expedited management of acute aortic dissection.
  • Integration into clinical workflows could improve diagnostic speed and patient outcomes.
  • The CNN-based approach offers a sensitive and accurate method for abdominal AD detection.
