What is the difference between MRI and MRA?

Magnetic resonance imaging (MRI) provides general display of the inside of the body, while magnetic resonant angiography (MRA) offers a specific picture of blood vessels. Scans MRA uses MRI technology, but provides narrower focus than would be available with regular MRI studies. The key difference between MRI and MRA is their intended use and application, because MRA is used for a very specific purpose, while MRI can be used in many different environments. In the MRI study, the patient enters a tube with powerful magnets used to collect a non -invasive range of pictures from the body. This is done with a high degree of resolution and without exposure to radiation. MRI can be taken from any body area and some may include the use of contrasting materials to highlight certain structures inside the patient. The scans of the whole body offer display from head to toe, while other scanning can grow into areas of interest, such as knee injury or suspect abdominal cancer.

For a view of blood vessels with MRA studies, the care provider injects a contrasting material that highlights the blood vessels. The device can be placed on specific areas such as a leg or can run all over the body. Doctors may ask MRA for a suspicion of a blood clot to evaluate the blood flow in the body area and check obstacles. Unlike other angiographic techniques, it offers detailed display in a non -invasive way.

The patient may need scanning MRI and MRA to collect health information, depending on the nature of the problem and the recommendation of the doctor. These scanning can be used during the diagnostic phase to collect information about what is happening inside the patient. They can also be useful in monitoring for monitoring of recovery. Doctors can compare newer and older studies to determine how well the patient responded to treatment and checked complications.

ExperienceMRI and MRA is very similar. In both cases, the patient must lie down and hold as much as possible inside the machine. Open machines allow greater comfort when patients feel claustrophobic, while older closed models can be stressful to some patients. Care providers can offer headphones with music and other distractions for their patients while scanning MRI and MRA, along with the emergency stop button in case of extreme discomfort.
