目的探讨数字化X射线摄影(DR)、计算机体层摄影术(CT)和磁共振成像(MRI)诊断骨肿瘤的临床价值。方法回顾性分析2010年11月至2013年2月收治的45例骨肿瘤患者,45例患者全部有DR检查,其中35例行CT检查,21例行MRI检查。结果 DR和CT在显示骨肿瘤的骨质破坏、增生、硬化和病灶边界上均是类似的,但是DR在显示脊柱、颅底和骨盆病灶时不如CT明显,细微如针尖样病灶时CT更加明显,且在显示软组织阴影上较DR明显。DR在显示骨膜反应上情况最好,MRI则在显示骨髓水肿和软组织肿块影上最有特异性,但是在显示骨质破坏、增生、硬化、钙化斑等方面情况最差。结论临床上诊断骨肿瘤仍要以DR为主,CT可显示肿瘤的范围和细微结构,而MRI则在显示软组织情况和脊髓水肿上有优势,临床上要结合病情选择诊断方式。
Objective To investigate the clinical value of digital radiography (DR), computed tomography (CT) and magnetic resonance imaging (MRI) in the diagnosis of bone tumors. Methods A retrospective analysis of 45 patients with bone tumors admitted between November 2010 and February 2013 was performed. All 45 patients had DR, of which 35 had CT and 21 had MRI. Results DR and CT were similar in bone destruction, hyperplasia, sclerosis and border of lesion. However, DR was not as obvious as CT in displaying spine, skull base and pelvic foci. CT was more obvious in subtle tip-like lesions , And show a soft tissue shadow more obvious than DR. DR showed the best periosteal response, while MRI showed the most specific bone marrow edema and soft tissue mass, but showed the worst cases of bone destruction, proliferation, sclerosis and calcification. Conclusion The clinical diagnosis of bone tumors should still be dominated by DR, CT can show the scope of the tumor and the fine structure, and MRI showed soft tissue conditions and spinal cord edema on the advantages of clinically combined with the disease diagnosis method.
