Magnetic Resonance (MR) Portal Venous Study is a specialized medical imaging technique that helps in the evaluation of the portal vein and the venous system of the liver. The portal vein is a major blood vessel that carries blood from the digestive organs to the liver. It is essential for the detoxification and processing of nutrients. Understanding the state of the portal vein and the surrounding structures can be critical for diagnosing and managing various liver and digestive system conditions.

The MR Portal Venous Study utilizes magnetic fields and radio waves to create detailed images of the portal vein. Unlike traditional X-rays, this technique does not involve ionizing radiation, making it a safer option for patients.

Specific Instructions:

• Fasting and Preparation : You might be asked to fast for a certain period, usually 4-6 hours before the examination. This reduces the likelihood of having any undigested food which might interfere with the images.
