Abstract:
Objective To evaluate the imaging quality and diagnostic value of different MR sequences for abnormalities of knee cartilage. Methods Three sequences of MR, including double echo steady state (DESS), multi echo data imagine combination (MEDIC) and true fast imaging with steady state precession (TrueFISP) were performed in 18 healthy volunteers. Signal-to-noise ratio (SNR) of knee cartilage and contrast-to-noise ratio (CNR) to surrounding tissues were measured and compared. Results SNR of cartilage was the highest in MEDIC sequence imaging, CNR of cartilage-synovia was the highest in DESS sequence imaging among three sequences (P<0.05). Conclusion Compared with the other sequences, DESS seems to be optimal in diagnosis of abnormalities in knee cartilage.
