目的:对全身MRI在骨转移瘤中的诊断价值做出评价进行探讨。方法:将本院于2006年4月~2012年4月收治发现的50例患有骨转移瘤的患者,根据其意愿将其随机分成两组,分别为试验组25例,对照组25例,给对照组的25例患者采用同位素骨扫描的方法,对该部位的病变进行扫描并显示情况,给试验组的25例患者,采用MRI扫描的方法,对部位的病变进行扫描并显示情况,观察两组患者经过不同扫描诊断后的结果。结果:共50例患者参与了本组研究,其中25例患者通过MRI共检查了100个部位(脊柱21个、肋骨14个、骨盆28个、四肢19个、胸部13个、颅骨5个),在MRI的扫描范围之内,将病灶数目作为统计的单位,确诊为骨转移瘤的共有298个病灶。在MRI上,假阴性有5个,真阳性有293个,没有假阳性,诊断的敏感性高达98.6%。在同位素骨扫描上,假阴性有57个,真阳性有201个,假阳性40例,诊断的敏感性高达77.2%。结论:在骨转移瘤的显示方面,同位素骨扫描比MRI扫描的敏感性低,但是MRI在扫描的过程中会受到范围上的限制。
Objective: To evaluate the diagnostic value of whole body MRI in bone metastases. Methods: Fifty patients with bone metastases discovered in our hospital from April 2006 to April 2012 were randomly divided into two groups according to their wishes: 25 in the experimental group, 25 in the control group, Twenty-five patients in the control group were subjected to isotope bone scan to scan and display the lesion. Twenty-five patients in the test group were screened by MRI and the lesions were observed and observed. Two groups of patients after different scan diagnosis results. RESULTS: A total of 50 patients participated in this study. Twenty-five of the 25 patients examined 100 sites (21 spine, 14 ribs, 28 pelvis, 19 limbs, 13 thorax, 5 skulls) Within the scope of MRI scans, the number of lesions as a statistical unit, diagnosed with bone metastases of a total of 298 lesions. On MRI, there are 5 false negatives, 293 true positives, no false positives, and a diagnostic sensitivity of 98.6%. In isotope bone scan, there were 57 false negatives, 201 true positives and 40 false positives, with a diagnostic sensitivity of 77.2%. CONCLUSION: Isotopic bone scans are less sensitive than MRI scans in the display of bone metastases, but MRI may be limited in scope during scanning.
