Objective To compare SNR and CNR of bone marrow changes of knee osteoarthritis between four sequences, such as T1-sag, T1-vibe, PD-sag and T2-fssag, so as to find out the optimal sequence to diagnose the disease. Methods 36 patients suffering knee osteoarthritis were selected to perform T1-sag, T1-vibe, PD-sag and T2- fs-sag scanning between January to June, 2014 in our hospital. Results The values of SNR were 111.82±61.39, 14.53±4.73, 77.57±39.98 and 189.44±89.98 respectively, when scanned by T1-sag, T1-vibe, PD-sag and T2-fs-sag sequences. And the values of CNR were 194.27±92.43, 14.08±15.39, 79.23±40.29 and 153.29±81.40 respectively. The value of SNR was highest when scanned by T2-fs-sag, and then followed by T1-sag, PD-sag and T1-vibe. The value of CNR was highest when scanned by T1-sag, and then followed by T2-fs-sag, PD-sag and T1-vibe. Conclusion MR sequences imaging could offer information of bone marrow changes of knee osteoarthritis, and T2-fs-sag and T1- sag might be the relative optimal sequences to diagnose the disease.
