Summary
Modern neuroimaging using computed tomography (CT) and magnetic resonance imaging (MRI) offers advanced diagnostics but carries new risks. These include radiation exposure, contrast media complications, and magnetic field hazards, requiring careful patient consideration.
Area of Science:
- Neurology
- Radiology
- Medical Imaging
Background:
- Computed tomography (CT) and magnetic resonance imaging (MRI) have transformed neuroimaging.
- These advanced techniques present new risks alongside benefits, necessitating careful evaluation.
Purpose of the Study:
- To outline the risks associated with modern neuroimaging techniques.
- To inform clinicians about potential complications before ordering neuroimaging procedures.
Main Methods:
- Review of risks associated with CT scans, including radiation exposure.
- Analysis of MRI risks, encompassing static magnetic fields, gradients, and contrast agents.
- Evaluation of neurointerventional techniques and their associated complications.
Main Results:
- CT imaging poses risks of significant radiation exposure.
- Contrast agents can cause complications, particularly in patients with renal failure.
- MRI involves risks from magnetic fields, gradients, and contrast media.
- Neurointerventional procedures carry risks such as embolization and bleeding.
Conclusions:
- Clinicians must carefully weigh the benefits against the risks of CT, MRI, and neurointerventional procedures.
- Awareness of potential complications like radiation exposure and contrast nephropathy is crucial for patient safety.

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...

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...
