Magnetic Resonance Imaging01:24

Magnetic Resonance Imaging

7.1K
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...

Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...

Imaging Studies for Cardiovascular System IV: CMRI

137
Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...

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...

Area of Science:

  • Medical Imaging
  • Neurology
  • Biomedical Engineering

Background:

  • Conventional MRI requires patient transport, posing risks for critically ill individuals.
  • High-field MRI may be contraindicated for patients with certain medical devices.
  • Ultra-low-field MRI offers potential advantages in safety and accessibility.

Purpose of the Study:

  • To provide an overview of the Hyperfine Swoop Portable MR Imaging System.
  • To present clinical experience and representative images from over 500 patients.
  • To evaluate the utility of portable MRI as an adjunct to conventional MRI.

Main Methods:

  • Clinical experience with the Swoop Portable MR Imaging System (>500 patients).
  • Demonstration of scanner characteristics and scan procedures.
  • Presentation of representative clinical images, including artifact reduction and contrast enhancement.

Main Results:

  • Portable MRI is a valuable adjunct for critically ill patients, minimizing transport risks.
  • Ultra-low-field MRI reduces susceptibility artifacts, allowing scans in patients with dental amalgam.
  • Safe scanning was achieved in a patient with a non-MR-conditional pacemaker.
  • Contrast enhancement was detectable at ultra-low-field using standard-dose gadolinium.
