CartiGram is a T2 mapping sequence and processing utility used to non-invasively detect changes in the collagen component of the extracellular cartilage matrix. This technique acquires multiple echoes at different TE times at each slice location that represent different T2 weighting. The acquired data can be processed to produce T2 color maps which demonstrate more subtle changes in cartilage ultrastructure that are not visible on gray scale MR images.
“These images provide us with objective information of the cartilage ultrastructure. In this case, it may aid in timing patellar re-alignment procedures.”
