Research on the distribution difference of MRI signals in osteonecrosis of the femoral head patients of different TCM syndrome types / 中国中西医结合杂志

ABSTRACT

<p><b>OBJECTIVE</b>To observe the distribution difference of magnetic resonance imaging (MRI) signals in osteonecrosis of the femoral head (ONFH) patients of different TCM syndrome types.</p><p><b>METHODS</b>Recruited 29 ONFH patients were assigned to the tendon and vessel stagnation group (14 cases) and the Gan-Shen deficiency group (15 cases) according to TCM syndrome typing. The distribution difference of their MRI signals of MRIT1WI, T2WI + fs, T1 and T2 combined signal were compared.</p><p><b>RESULTS</b>There was statistical difference in T1W1 signal distribution between the two TCM syndrome types (P = 0.04). There was no statistical difference in T2WI + fs or T1 and T2 combined signal between the two TCM syndrome types (P = 0.42, P = 0.15). MRI signals in the tendon and vessel stagnation group were mainly manifested as fat-like signals,while they were mainly manifested as mixed signals in the Gan-Shen deficiency group.</p><p><b>CONCLUSION</b>Distribution difference of MRI signals exists between ONFH patients of different TCM syndrome types.</p>
