What are the different MRI types with contrast?

Magnetic resonance imaging (MRI) is a type of display that doctors use to shoot the inside of the body. The contrast is the term used to describe special dyes that can be used in MRI tests. MRI with contrast allows doctors to see improved pictures of specific areas. The type of contrast used varies depending on what the doctor tries to get pictures and diagnose. Contrast reagents are classified into categories based on which body area provides contrasting images. MRI tests are similar to X -rays. The difference is that this particular type of medical imaging gives doctors images of soft tissue in the body, while standard X -rays can only detect hard parts such as bone. Using images MRI without contrasting agent can be used for comparison with contrast images. The aim is the abdominal area, including the stomach and intestines. In general, the dyes are administered orally and are positive or negative. Positive contrast makes the area clearer than the surroundings. Negative contrast provides darker areas in the pictures.

intravascular substances are used in MRI with contrast focused on veins, arteries and hearts. These contrasts help doctors look for dead tissue. They can also be used to detect tumors in this area. In some cases, abnormalities that may occur in veins or arteries may be visible.

tumor -specific agents are used for MRI with contrast used in diagnostic cancer. Common types of contrast agents include monoclonal antibodies and metaloporphins. Metaloporphyrins are used to detect sarcoma and lymphoma tumors, in addition to tumors that occur in melanoma and carcinoma. Monoclonal antibodies are often used to detect specific tumors such as those that occur in adenocarcinoma.

for MRI with contrastThe liver, gallbladder and biliary areas are used by hepatobiliary substances. These contrasts can help doctors find masses in the liver. They can also provide monitoring of damage caused by cirrhosis of the liver and other such diseases. As a result of the contrast agent, they remain effective, higher resolution is available for a longer time before visibility decreases.

Lymph nodes are possible using MRI with contrast. This MRI uses Ultra-Mamils ​​Iron Oxide (USPIO) as a contrasting agent. When USPIO is introduced into the body through intravenous injection, it heads directly to the lymph nodes. In this contrast agent, doctors are able to determine whether enlarged lymph nodes are present. It also helps to distinguish cancer nodes from healthy knots.
