Having a Brief Understanding on the MRV Procedure
Are you familiar with medical imaging? The chances of you hearing about a variety of procedures inclusive of magnetic resonance imaging or MRI would be higher. However, if you have been told that you require a magnetic resonance venography or MRV, you may be wondering about the term and the procedure.
Similar to MRI, the MRV does not use radiation for producing an image. It enables the physician to have a clearer vision of what has been taking place inside your body. The MRV has been specifically designed whereby enabling your doctor to examine your blood vessels.
The MRV would be best described as a precise and noninvasive imaging technique used for focusing on the veins of the body and determining the health of the vein. The veins bring blood from the organs of the body back to the heart where it would regain essential nutrients through oxygenation.
The MRV would assess the flow of blood and detect any detrimental abnormalities such as blood clots. Moreover, this imaging technique would uncover additional conditions inclusive of blood flow issues in the brain, structural vein abnormalities, and deep thrombosis in the veins.
The MRV could assist in helping evaluate different conditions that could cause neurological symptoms inclusive of normal pressure hydrocephalus and intracranial hypertension.
Equipment used for MRV
MRV uses similar equipment as used in MRI. The MRI machines would use magnets for capturing information and send it to a computer having software for interpreting the meaning of the received information. This information would be used for creating images to be used for determining your medical condition. While the MRV does not use radiation, patients would be required to receive an injection of a contrast material known as gadolinium for optimizing results. The injections would have rare allergic reactions. The MRV is relatively comfortable. However, it might be challenging for claustrophobic patients, as they have to lie inside a tubular imaging machine for a significant length of time.
If you tend to get easily nervous or uncomfortable lying on your back, you may be prescribed a relaxant or pain medication for making the procedure more comfortable.
Due to the imaging machine using magnets, you could determine the safety of any metals device in the body through a screening questionnaire. Patients would require removing their jewelry and encouraged to listen to music during the exam, as the imaging machines are significantly loud.
A patient could return to their normal routine activities after an MRV as long as they have not taken any relaxation medication. This comfortable and precise imaging procedure enables the doctors and patients to seek the answers they require about vein health.
