摘要
目的探讨煤矿采掘振动作业工人腕关节的核磁共振(MRI)表现。方法选择符合手臂振动病诊断标准的振动作业工人43名和非振动作业工人20名分别作为观察组和对照组。全部进行MRI检查,将两组MRI图像进行对比分析,并将观察组患者按不同接振时间分为5组,观察分析MRI征象的发展规律。结果观察组的MRI征象中,以关节积液最多,与对照组比较,差异有统计学意义(x^2=8．80,P＜0．01)；骨质疏松和骨质硬化与对照组比较,差异亦有统计学意义(x^2值分别为3．91,5．01,P＜0．05)；骨髓水肿和腕骨坏死只在观察组中出现,对照组中未观察到。关节积液和骨髓水肿发生高峰出现在接振早期。桡骨远端骨髓水肿信号在GE T_2WI序列中降低,有特异性。结论(1)腕部骨关节改变于接振早期即已出现并可由MRI检查发现；(2)桡骨远端骨髓水肿在手臂振动病诊断中有重要价值。
Objective To study the magnetic resonance imaging（MRI） in the wrist joint of coal miners who work in excavation and vibration department. Methods Forty-three coal miners with the hand-ann vibration disease served as the observation group while 20 workers who were not working in the vibration department acted as the control group. The patients in the observation group were divided into five subgroups according to the time when they received vibration. The regularity of the development of signs and symptoms of MRI was observed and analyzed. Results The hydroarthrosis was most found in MRI. There were significant difference in hydroarthmsis（ X^2 = 8.80, P 〈 0.01 ）, osteoperosis and osteomyelitis（ X^2 = 3.91, X^2 = 5.01, P 〈 0.05 respectively） between the obsorvation group and the control group. The edema of bone marrow and the avascular necrosis of ossa carpi were found only in the observation group and not found in the control group. The hydroarthrosis and the edema of bone marrow occurred most in the early stage of vibration, The signal in the edema of tire bone marrow of the distal end of the radius was decreased in the GE sequence T2WI with the specificity. Conclusion （ 1 ） Changes in the wrist joint occur in the early stage of the vibration work, and can be found in the MRI. （2）The edema of the bone marrow of the distal end of the radius is of great value in the diagnosis of the hand-arm vibration disease.
