Imaging Studies for Cardiovascular System IV: CMRI

440
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,...

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...

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...

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,...

Area of Science:

  • Medical Imaging
  • Cardiology
  • Biomedical Engineering

Background:

  • Cardiac implantable electronic devices (CIEDs) are common in patients requiring MR imaging.
  • Historically, CIEDs were an absolute contraindication for MR imaging due to safety concerns.

Purpose of the Study:

  • To review CIEDs relevant to MR imaging.
  • To discuss the physics and technical factors of scanning patients with CIEDs.
  • To present a multidisciplinary screening protocol for safe MR imaging in patients with CIEDs.

Main Methods:

  • Review of current CIEDs and MR imaging physics.
  • Development and implementation of a multidisciplinary screening protocol.
  • Analysis of institutional experience scanning CIED patients since 2010.

Main Results:

  • Growing evidence supports the safety of MR imaging in most patients with CIEDs under specific conditions.
  • The presented protocol facilitates safe MR imaging examinations for patients with CIEDs.

Conclusions:

  • MR imaging can be safely performed in patients with CIEDs when appropriate screening and protocols are followed.
  • This approach expands diagnostic capabilities for patients with CIEDs.
