Imaging Studies I: CT and MRI

702
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...

Summary

Comparing CT reconstruction algorithms, Full model-based iterative reconstruction (full MBIR) excels at reducing edge artifacts, while single energy metal artifact reduction (SEMAR) is optimal for larger implants and low-dose scans.
