Ultrashort echo time (UTE<1ms) imaging has advantages over traditional long TE (>10ms) imaging to detect asymptomatic (subclinical) cartilage damages in the knee joint, such as fissuring, fracturing and collagen fiber breakdown. To advance UTE imaging toward clinical use, its long scan time needs to be reduced to meet clinical requirement of short protocols. Compressed sensing (CS) and sensitivity encoding (SENSE) parallel imaging have the potential to do so. However, individual use of them has limitations. A combined use of both techniques has been shown in dynamic imaging to be able to achieve higher acceleration factor without SNR loss. This study explores the technical feasibility to extend CE+SENSE to static UTE imaging.
