From: T2 mapping for knee cartilage degeneration in young patients with mild symptoms
Sagittal fat-suppressed proton density weighted turbo spin-echo sequence images from the right knee cartilage of a 26-year-old male patient. Each region is equally divided into superficial and deep layer. Blue areas show lateral (a) and medial (b) patella cartilage. a and c illustrate lateral and medial cartilage of the tibiofemoral joint, respectively. Red, green and yellow areas represent the anterior, central and posterior cartilage, respectively. The ROIs size of this subject are 92, 105, 88, 102, 109, 102, 154, 148, 165, 168, 178, 183, 148, 133, 138, 130, 78, 83, 96, 98, 105, 94, 76, 77, 95, 97, 86, and 91 pixels (order according to Table 2)
