Needle-Free Cartilage Assessment
CartiGram is a non-invasive MRI method to assess articular cartilage integrity. This powerful diagnostic tool provides objective information of the cartilage ultrastructure and allows clinicians to visualize collagen fiber degradation without gadolinium injection.
When collagen breaks down, there is increased mobility of water in the cartilage, detected by MRI. CartiGram color mapping shows subtle changes in cartilage composition not visible on gray-scale MR images, and often at earlier stages.
For the preparation for an MRI Scan, the doctor may want to know if you are allergic to anything, are pregnant, allergic to any medicines and would like to know about your normal health condition. Doctors should also be informed if there are any metal plates or other implantations in your body, if you have had any previous surgeries or operations, or if you wear any medical patches etc. You may want to arrange someone to drive you home after the MRI Scan as the sedative given may need you to relax.
Different MRI Scans need different kinds of guidelines and preparations. For example, for the MRI Scan of the abdomen and pelvic area, doctors may ask you not to drink or eat for several hours before the test.
A special dye which is known as contrast material is required for MRI Scans which help to highlight the body parts or organs which will be going under scan. What this material does is that it helps in blocking the x rays and comes as white in the images obtained. This white color can help emphasize on the organs or vessels.
