What diseases can MRI detect?

Magnetic resonance imaging (MRI) is a medical examination technology that uses magnetic fields and radio waves to produce detailed images of the inside of the human body. Due to its non-radiation and high resolution, MRI is widely used in clinical diagnosis. This article will introduce in detail the types of diseases that MRI can detect and display relevant information through structured data.

1. Common diseases examined by MRI

3. Comparison between MRI and other imaging examinations

MRI has unique advantages and limitations compared with other imaging examination methods such as CT and X-ray. Here's how MRI compares to other examination methods:

Check methodAdvantageslimitations
MRINo radiation, high soft tissue resolutionInspections take a long time and are expensive
CTFast inspection and clear bone imagingRadiation, soft tissue resolution is low
X-rayEasy to operate and low costThere is radiation and can only display two-dimensional images.

4. Precautions for MRI examination
