A prospective study was performed to compare the results of quantitative radionuclide bone scanning with those of sacroiliac joint anesthetic block in patients with unilateral low back pain. Thirty-four subjects, forming the control group, underwent quantitative radionuclide bone scanning of the sacroiliac joints. The normal values in sacroiliac uptake difference were taken to be between -1.7% and +6.2%. Thirty-two patients with chronic unilateral low back pain underwent sacroiliac bone scanning and sacroiliac joint block. Six of the seven patients with increased uptake > 6.2% on the painful side had at least 75% pain reduction in response to the block. The sensitivity, specificity, and positive and negative predictive values of the quantitative bone scanning in the unilateral mechanical sacroiliac joint syndrome were 46.1%, 89.5%, 85.7%, and 72%, respectively.
进行了一项前瞻性研究，以比较单侧下腰痛患者定量放射性核素骨扫描与骶髂关节麻醉阻滞的结果。34名受试者组成对照组，接受了骶髂关节的定量放射性核素骨扫描。骶髂摄取差异的正常值为-1.7%至+6.2%。32例慢性单侧下腰痛患者接受了骶髂骨扫描和骶髂关节阻滞。疼痛侧摄取增加>6.2%的7例患者中，有6例对阻滞的反应是疼痛至少减轻75%。单侧机械性骶髂关节综合征定量骨扫描的敏感性、特异性、阳性和阴性预测值分别为46.1%、89.5%、85.7%和72%。
