Magnetic resonance imaging, or MRI, is a type of imaging diagnostic
procedure that combines powerful magnetic fields and radio waves in
a controlled environment to produce high-resolution images of organs,
tissues, and bones. It is an important tool for identifying and
diagnosing a variety of illnesses. This image diagnostics approach
outperforms a CT scan because it generates 3D images with greater
depth and clarity for diagnosis.
The sort of MRI scan that the doctor advises is determined by
the medical problem that the test is being performed for. The following are
the most common types of MRI scans:
- Magnetic Resonance Venography:
: MRV (Magnetic Resonance Venography) employs an intravenous contrast
dye to view and monitor the veins. The MRV gives a clear picture of the
veins and blood vessels, and it's used to figure out what's causing leg
pain and other vein problems.
- Cardiac MRI:
As the name implies, a cardiac MRI is used to diagnose cardiovascular problems.
This form of MRI scans the heart and its structures in order to find and diagnose cardiac problems.
- Functional MRI:
This sort of MRI scan is utilized to observe the patient's brain activity by monitoring
blood flow. The blood flow in the brain region that is currently being used has risen.
Functional MRI is used to map the functional areas of the brain.
- Magnetic Resonance Angiography:
MRA, or Magnetic Resonance Angiography, scans and observes the movement of blood
arteries using contrast material. This MRI scan type is generally used to measure
blood flow while scanning the heart and soft tissues.
