A medical imaging technique that uses strong magnetic fields and radio waves to produce detailed images of the inside of the body. In Japanese, it is almost always referred to by the abbreviation MRI, pronounced エムアールアイ.
Referring to the procedure or technology of magnetic resonance imaging.
The universally understood abbreviation in Japanese. Used in both spoken and written contexts, from casual conversation to medical reports.

The MRI results showed no abnormalities.
The full formal term. Rarely used in everyday conversation; mainly found in academic papers, medical textbooks, or official documents.
磁気共鳴画像法は放射線を使用しない。
Magnetic resonance imaging does not use radiation.
Talking about undergoing an MRI examination.
The most common way to say 'MRI scan' or 'MRI examination'. 検査 means 'examination' or 'test'.
MRI検査を受けることになりました。

The standard term for the MRI machine or device. 装置 means 'equipment' or 'apparatus'.

In Japanese, the full term 磁気共鳴画像法 is almost never used outside of highly technical contexts. Even in medical settings, doctors and patients say 'MRI' (エムアールアイ). Using the full term may sound overly formal or pedantic.
In Japanese, CT scan is 'CT' (シーティー) or 'CTスキャン'. Both are common imaging techniques, but MRI uses magnets while CT uses X-rays. When explaining the difference, you can say: MRIは磁石、CTはX線を使います。
MRIは磁石、CTはX線を使います。
MRI uses magnets, and CT uses X-rays.
