MRI Perfussion

Magnetic Resonance Imaging (MRI) Perfusion is a highly specialized medical imaging technique that evaluates the flow of blood through the organs and tissues. By using a strong magnetic field combined with radiofrequency waves, MRI Perfusion provides intricate details regarding the blood supply and distribution within various areas of the body.

MRI Perfusion is particularly useful in assessing blood flow, which is fundamental to understanding the functionality of organs and the existence of certain conditions. For instance, it is commonly used in the evaluation of brain tissue in stroke patients or identifying tumors based on the blood supply.This technique allows doctors to observe minute physiological changes by looking at the amount and speed of blood flowing through capillaries and tissues. This information is vital in diagnosing various disorders, determining the severity of diseases, and making informed decisions regarding treatment options.

• Fasting : Your doctor might instruct you to fast for a certain number of hours before the procedure, especially if a contrast agent is to be used.
• Clothing : Wear comfortable clothing free of any metallic components as the MRI utilizes a strong magnetic field. You might be asked to change into a hospital gown.
• Medical History and Allergies : Inform the radiologist or technician if you have any allergies, especially to gadolinium (contrast agent), or if you have any implants or devices such as a pacemaker, as some of them may be incompatible with an MRI scanner.
• Pregnancy : If you are pregnant or suspect that you might be, inform your doctor as the effects of MRI on the fetus are not completely known.
• Claustrophobia : If you suffer from claustrophobia, notify your doctor ahead of time. They might prescribe medication to help you relax.

The procedure takes place in a hospital or diagnostic center. You will lie down on a sliding table that moves into the MRI machine, a large tube-shaped device. If a contrast material is needed, it will be administered through an IV line. You must remain very still during the scan to ensure clear images. The machine can be quite noisy, and you might be provided with earplugs or headphones to minimize the noise.

• Detailed Images: This procedure can reveal detailed images of blood flow within the organs, helping in the early detection of diseases.
• No Radiation: MRI Perfusion does not use ionizing radiation, making it safer for patients who require multiple images over time.
• Treatment Planning: It is vital in planning treatment, especially in cases of stroke, tumors, and blood flow disorders.
• Evaluating stroke
• Detecting and monitoring tumors
• Evaluating blood flow disorders
• Assessing brain functionality in certain conditions

MRI Perfusion provides detailed information regarding the blood flow within tissues. It can identify areas with restricted blood flow or increased permeability, which is essential in diagnosing and treating various conditions.

How Often Should You Be Tested?

MRI Perfusion is not a routine test and is usually only prescribed by doctors for specific diagnostic or treatment monitoring purposes.

• Modifiable Factors: Movement during the scan, poor contrast injection techniques.
• Non-Modifiable Factors: Patient’s age, medical history, or specific medical devices.
