What is MRI with contrast?
MRI means magnetic resonance imaging ; In principle, it uses powerful magnets and radio waves to create detailed images of your body interior. This can be done with or without contrast. The contrast is the type of dye that is injected intravenously either just before or during the procedure. Some abnormalities, such as tumors, absorb dye and very clearly appear on MRI with contrast. Your doctor will determine whether you need MRI with or without contrast and without it and you can order both tests. MRI scan generally creates brighter images with much more detail than X -ray or CT scanning. Small tumors that can be invisible in X -ray or CT scan can be detected by MRI. In the case of most cancer, earlier treatment is initiated, the better the result of treatment, so early scanning MRI any suspicious area can literally mean the difference between intermediate and death.
equally good jAKO Standard image MRI is, the image can be further improved by adding contrast. Tumors and other abnormalities absorb the contrasting dye as it proceeds through your blood vessels, and when scanning MRI this area will shine. This allows you to detect even the smallest tumors, and also gives your doctor a clearer idea of the position and size of the tumor and about which organs or tissues are involved. In addition, the contrast allows physicians to observe functional abnormalities that are not visible in regular scanning, especially problems with how well your blood flows through your blood vessels.
The contrast medium used in MRI, usually Gadolinium, is different from contrasting dyes used in X -ray or CT scans. Adverse effects on Gadolinium are much more rare than iodine -based dyes. However, if you have an unusual kidney function, you may be a resistant risk of nephrogenic systemic fibrosis caused by MRI dye. This complication is very rare, but always make sure your doctor and radiological tThe echnik is aware of any health problems or allergies that you can have before any type of contrast dye is injected. Most people tolerate MRI with contrast in order and the benefits of early tumor detection generally outweigh the smaller risks associated with dye.
MRI with contrast is generally painless, but you can experience some discomfort with an IV or needle used to injure dye. You will be placed on the table and place it so that the scan is most clearly displayed by the affected area. You can be slipped inside a long narrow tube in a closed MRI, or you can have an open MRI in which the scanning device is shaped as a large donut and only a part of the body to search. The imaging process itself can take 45 minutes to two hours and can be offered headphones so you can listen to music during scanning. Once the scan is completed, the radiologist reads and interprets scanning and your doctor will discuss the results with you.
