目的探讨单光子发射计算机断层成像术(SPECT)脑静态显像的临床应用。方法选取平煤神马医疗集团总医院2013年8月-2015年8月42例脑恶性肿瘤患者,采用CT和SPECT进行诊断,观察其临床价值。结果 SPECT与螺旋CT增强扫描临床诊断阳性率分别为97.06%(66/68)和89.71(61/68),差异无统计学意义(P>0.05);放射治疗DT 40 Gy后肿瘤明显消退,病灶CR为22个,PR为30个,NR为14个,NR的14例病灶中10例是经脑胶质瘤术治疗后存在的残留灶,其总有效率为76.47%。3次核素脑瘤显像平均T/N值,实施放射治疗前为1.5±0.4,20 Gy治疗后为2.0±0.5,40 Gy治疗后为1.5±0.5,在放射治疗20Gy时,T/N值显著提高,放射治疗40 Gy时T/N基本恢复正常。结论 SPECT脑静态显像对脑恶性肿瘤具有明显临床价值。
Objective To investigate the clinical application of single photon emission computerized tomography (SPECT) brain static imaging. Methods Forty-two patients with malignant brain tumors from Pingdingshan Shenma Medical Group General Hospital from August 2013 to August 2015 were diagnosed by CT and SPECT, and the clinical value was observed. Results The positive rates of SPECT and spiral CT in clinical diagnosis were 97.06% (66/68) and 89.71 (61/68), respectively, with no significant difference (P> 0.05) CR was 22, PR was 30, NR was 14, NR of 14 lesions in 10 cases of residual glioma after treatment of residual disease, the total effective rate was 76.47%. The average T / N of 3 nuclide brain tumor imaging was 1.5 ± 0.4 before radiotherapy and 2.0 ± 0.5 after 20 Gy treatment and 1.5 ± 0.5 after treatment with 40 Gy radiotherapy. At 20 Gy of radiotherapy, T / N The value of T / N returned to normal after radiotherapy 40 Gy. Conclusion SPECT brain static imaging has obvious clinical value on malignant brain tumors.
