Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy

57
This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...

Magnetic Resonance Imaging01:24

Magnetic Resonance Imaging

5.0K
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...

Gastric Motility01:16

Gastric Motility

505
Gastric motility is the coordinated contraction and relaxation of stomach muscles that convert ingested food into chyme, a semi-liquid substance ready for further digestion in the intestines. The process begins with the vagus nerve inducing the relaxation of the smooth muscles in the fundus and body of the stomach, allowing these regions to expand and accommodate up to approximately 1.5 liters of food and liquid.
Peristaltic Waves and Chyme Formation
Upon food entry, the stomach initiates...

    Area of Science:

    • Neurogastroenterology
    • Medical Imaging
    • Rodent Physiology

    Background:

    • Preclinical research on gastric physiology in rodents is crucial for neurogastroenterology.
    • Existing methods for studying gastric function are often invasive, terminal, or lack sufficient resolution.
    • There is a need for non-invasive, high-resolution techniques to assess gastric dynamics in vivo.

    Purpose of the Study:

    • To develop a standardized, non-invasive magnetic resonance imaging (MRI) protocol for capturing whole-stomach dynamics in anesthetized rats.
    • To achieve high spatiotemporal resolution for detailed analysis of gastric motility.
    • To establish a robust imaging framework for preclinical gastrointestinal research.

    Main Methods:

    • Utilized a 7-Tesla MRI system with a modified multi-slice gradient-echo sequence.
    • Employed gadolinium-doped test meals for enhanced intraluminal contrast in T1-weighted MRI.
    • Integrated respiratory gating, spatial saturation, and slice grouping for motion artifact reduction and improved contrast.
    • Accelerated image acquisition using k-space undersampling and reconstructed data with k-t interpolation.

    Main Results:

    • Successfully imaged gastric anatomy, volume, and pseudo-periodic dynamics in anesthetized rats.
    • Demonstrated clear visualization of gastric motility with homogeneous contrast from the gadolinium-doped meal.
    • Validated the k-t interpolation method for reliable estimation of antral contraction amplitude, velocity, and frequency.
    • Achieved rapid acquisition (24 slices in < 3 s) capturing antral contractions at approximately 5 cycles per minute.

    Conclusions:

    • Established an accessible and standardized non-invasive MRI protocol for dynamic gastric imaging in rats.
    • The protocol includes contrast meal preparation, animal handling, and a comprehensive acquisition/reconstruction framework.
    • This tool significantly advances preclinical gastrointestinal motility research by enabling robust study of gastric motility and dysmotility.
