目的观察磁共振弥散加权成像(diffusion weighted imaging,DWI)诊断脊柱转移瘤是否比单光子发射体层摄影(singie photon emission computed tomography,SPECT)具有优越性。方法对21例临床诊断脊柱转移瘤的患者进行常规DWI和SPECT检查。结果21例患者使用DWI技术检出脊柱转移瘤85灶,SPECT检出脊柱转移瘤69灶,DWI技术比SPECT具有更高的检出率(χ2=7.68,P<0.01)。结论应用DWI序列诊断脊柱转移瘤比SPECT具有更大的优越性。
Objective To investigate whether magnetic resonance diffusion weighted imaging (DWI) is superior to single photon emission computed tomography (SPECT) in the diagnosis of spinal metastases. Methods Twenty-one patients with clinically diagnosed spinal metastases underwent routine DWI and SPECT. Results Twenty-one patients were examined by DWI, 85 lesions were detected in spine metastases and 69 lesions were detected by SPECT. The detection rate of DWI was higher than that of SPECT (χ2 = 7.68, P <0.01). Conclusion DWI diagnosis of spinal metastases has more advantages than SPECT.
