PET/CT是将PET与具有高空间分辨率的螺旋CT安装在同一机架上,一次扫描可获得PET、CT及PET与CT的融合图像,达到了取长补短、信息互补的目的。两者将功能图像和解剖图像有机的结合在一起,显著提高了对小病变的诊断能力,有效减低了单纯PET或PET和CT融合图像的假阳性和假阴性,使对
PET / CT is the PET and CT with high spatial resolution mounted on the same rack, a scan can be obtained PET, CT and PET and CT fusion images, to achieve the strengths and weaknesses, the purpose of complementary information. The combination of both functional and anatomical images organically improves the ability to diagnose small lesions and effectively reduces the false positives and false negatives of simple PET or PET and CT fusion images,
