Insights

Pediatric foreign body ingestion of magnets can lead to severe complications. Screening with ferromagnetic detectors before MRI scans is crucial to prevent iatrogenic injuries in children.

Area of Science:

  • Pediatric radiology
  • Gastroenterology
  • Medical device safety

Background:

  • Foreign body ingestions are common in children, with most passing without issue.
  • However, certain ingestions, like magnets, can cause serious gastrointestinal complications.
  • Undisclosed ingestions pose diagnostic and management challenges.

Observation:

  • A child presented with severe neck pain, unrelated to an undisclosed ingestion of multiple magnets.
  • Magnetic resonance imaging (MRI) of the neck was performed to evaluate the neck pain.
  • The MRI scan is suspected to have caused intestinal perforations.

Findings:

  • The patient's undisclosed magnet ingestion led to a suspected iatrogenic complication during MRI.
  • Ferromagnetic detector screening prior to MRI could have prevented this intestinal perforation.
  • This case highlights the risks associated with magnetic foreign bodies and MRI.

Implications:

  • Instituting mandatory ferromagnetic detector screening for all pediatric patients before MRI is essential.
  • This policy change aims to prevent similar serious complications from magnetic ingestions.
  • Nationwide policy revision is recommended to enhance patient safety in pediatric 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...

Imaging Studies for Cardiovascular System IV: CMRI

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,...

Imaging Studies IV: Magnetic Resonance Imaging

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,...
Magnetic Susceptibility and Permeability01:31

Magnetic Susceptibility and Permeability

In linear magnetic materials, like paramagnets and diamagnets, magnetization is proportional to the magnetic field intensity. The constant of proportionality, a dimensionless number, is called magnetic susceptibility. The value of the susceptibility depends on the type of material.
When diamagnetic materials are placed under an external magnetic field, the moments opposite to the field are induced. Hence, the susceptibility for diamagnets has a minimal negative value of 10-5–10-6. Since...

Radiological Investigation II: MRI and Ventilation Perfusion Scan

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...
