应用SPECT(单光子发射计算机断层仪)对正常领骨30例和病人53例行SPECT颌骨静态显像,结果表明领骨良恶性肿瘤病变其SPECT静态像的核素浓集程度和方式、病变侧放射性计数(A)与健侧放射性计数(N)的比值(A/N)差异有高度显著性(P<0.005),病变范围大小同X线对照表明;当领骨肿瘤其SPECT静态图的病变范围明显大于X线显示的病变,则肿瘤的恶性可能性大。以上的结果为临床上对良恶性颌骨病变的鉴别提供了较重要的根据和定量筛选恶性病变的指标。 SPECT (single photon emission computerized tomography) on the normal collarbone and 53 cases of patients were performed SPECT static imaging of the jaw, the results show that benign and malignant tumors of the SPECT static image of the nuclear concentration and the way the degree of disease The ratio of side radioactive count (A) to contralateral radioactive count (N) (A / N) was highly significant (P <0.005), and the range of lesion size was similar to that of X-ray. Lesions were significantly larger than the X-ray showed lesions, the possibility of malignant tumors. The above results provide a more important basis for the identification of benign and malignant jaw lesions clinically and quantitatively screening malignant lesions.
