Magnetic Resonance Imaging

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Background:

Splanchnic blood flow assessment is crucial for understanding abdominal physiology and pathophysiology.
Clinical relevance exists for patients with altered abdominal blood flow, vascular neuropathy, or atherosclerosis.
Reliable, non-invasive methods for splanchnic blood flow measurement are needed.

Purpose of the Study:

To assess the reproducibility of non-invasive phase-contrast MRI (PC-MRI) for measuring splanchnic blood flow.
To evaluate the feasibility of PC-MRI for detecting postprandial blood flow changes.

Main Methods:

Utilized 2D PC sequences on 3 Tesla MRI scanners (Siemens and Philips).
Measured blood flow in the superior mesenteric artery, celiac trunk, hepatic artery, and portal vein in healthy individuals and type 2 diabetes patients.
Assessed reproducibility using coefficient of variation (CoV) and Bland-Altman analysis, and evaluated postprandial changes via oral glucose tolerance tests.

Main Results:

PC-MRI showed low intrasubject variability for the superior mesenteric artery, celiac trunk, and portal vein (within-session CoV: 7%-22%, between-session CoV: 16%-26%).
Hepatic artery measurements exhibited higher variability (within-session CoV: 12%, between-session CoV: 32%).
Glucose ingestion significantly increased blood flow in the superior mesenteric artery (88%) and portal vein (68%), which were robustly detected.

Conclusions:

Phase-contrast MRI is a reproducible and feasible technique for measuring blood flow in the superior mesenteric artery, celiac trunk, and portal vein.
PC-MRI can effectively detect postprandial changes in splanchnic blood flow.
This technique holds promise for clinical applications in patients with altered abdominal blood flow.
