Magnetic Resonance Imaging01:24

Magnetic Resonance Imaging

7.2K
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...

Imaging Studies IV: Magnetic Resonance Imaging

55
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,...

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...

Imaging Studies for Cardiovascular System IV: CMRI

138
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,...

Radiological Investigation II: MRI and Ventilation Perfusion Scan

226
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...

Area of Science:

  • Pediatric Radiology
  • Musculoskeletal Infections
  • Diagnostic Imaging Workflows

Background:

  • Magnetic resonance imaging (MRI) is crucial for diagnosing pediatric musculoskeletal infections (MSI).
  • Published protocols exist but are not consistently followed in pediatric centers.
  • Evaluating current MRI practices is essential for optimizing care.

Purpose of the Study:

  • To comparatively evaluate MRI processes and workflows for pediatric musculoskeletal infection (MSI) evaluations.
  • To assess variations in MRI acquisition strategies and outcomes across six Texas pediatric centers.

Main Methods:

  • Retrospective review of 70 pediatric patients undergoing MRI for suspected MSI over three years.
  • Surveys of pediatric orthopaedic surgeons assessed MRI protocols and satisfaction.
  • Analysis of demographics, diagnoses, MRI indications, processes, and outcomes.

Main Results:

  • Two centers with organized protocols and protected MRI time showed significantly shorter scan durations (median 21.0 vs. 52.0 min).
  • These centers used fewer MRI sequences (median 3.0 vs. 7.0) and less contrast (4.0% vs. 53.3%).
  • A substantially shorter delay from MRI to operating room was observed for surgical cases (median 26.0 vs. 967.5 min).

Conclusions:

  • Most studied centers did not adhere to organized MRI workflows for pediatric musculoskeletal infections (MSI).
  • Implementing multidisciplinary MRI protocols can enhance efficiency and provider satisfaction.
  • Optimized workflows are vital for this heavily scheduled diagnostic resource.
