Abstract

Insights

This guide helps neuroradiologists identify and differentiate common MRI artifacts from genuine pathology using basic physics principles. Understanding artifact causes aids in accurate diagnosis and troubleshooting.

Area of Science:

  • Radiology
  • Medical Imaging Physics

Background:

  • Magnetic Resonance Imaging (MRI) is a cornerstone of modern neuroradiology.
  • Image artifacts can mimic or obscure true pathology, complicating diagnosis.

Purpose of the Study:

  • To provide a comprehensive overview of common artifactual findings in neuroradiologic MRI.
  • To offer practical guidance for distinguishing artifacts from pathology based on physical properties.

Main Methods:

  • Explanation of artifact origins using fundamental Magnetic Resonance (MR) physics concepts.
  • Presentation of case illustrations demonstrating artifactual findings.
  • Discussion of physical properties to differentiate artifacts from pathology.

Main Results:

  • Artifacts in MRI are frequently encountered and can be challenging to identify.
  • Understanding the physical basis of artifacts is key to their recognition.

Conclusions:

  • Radiologists can develop effective troubleshooting algorithms for MRI artifacts.
  • Case illustrations and physics-based clues enhance the ability to differentiate artifacts from true pathology.

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...

Brain Imaging

Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans),  magnetic resonance imaging (MRI),  functional magnetic resonance imaging (fMRI), and Transcranial Magnetic Stimulation (TMS).
