Magnetic Resonance Image (MRI) is an examination doctors use through strong magnetic field and radio waves for the purpose of detecting, curing, and observing illness. An MRI is a method by which warning signs from internal organs are obtained and then analyzed by special computer programs. The radiologist is then able to interpret the results and find the underlying causes of possible diseases.
In order to be more precise and acquire a clearer image a contrast dye can be added to a standard MRI scan. Physicians using this procedure will be provided with a reading of even the smallest tumors, should these be present. Additionally this procedure will allocate the exact position and size of potential tumors and the organs and tissues these might have affected. Moreover the radiologist will be able to identify malformations that would not show up on a customary scan, such as abnormal vessel blood flow.
The contrast dye used in these MRI Scans is generally gadolinium as complications are rarer in comparison to the Iodine origin dye used for x-rays and CT scans. Some people may develop an allergic reaction to the dye but these have been known to be exceptional and rare. Another drawback might be the fact that the contrast dyes are costly. An MRI with contrast dye would be essential in cases such as indentifying the multiplication or spread of a malignant mass in the brain, and the liver among other vital organs. The process involves the dye being absorbed by the growths or other deformities as it moves throughout the blood vessels making the infected organ flush.
This method is normally simple and painless. The patient is placed on a table in a specific position so that the scan will show the affected part visibly and evidently. The discomfort is minor and present for the brief moment that the needle injection takes to insert the dye. The process will approximately take from 45 minutes to 2 hours during which the patient can listen to portable music or just relax.
Many different medical conditions can be detected through these scans. They can identify an illness before it develops or more importantly save lives. These scans are thorough and specialize in revealing a more detailed overview in showing abnormalities in bones, soft tissue, blood vessels, the brain and the heart just to name a few.
