The main difference between these two sophisticated imaging techniques is that CT (computed tomography) scans use X-rays while MRIs (magnetic resonance imaging) use radio waves. Both of them create detailed images of inner tissues and organs, but are used for different reasons depending on the ...
PET是功能成像 CT MRI是解剖成像 PET：灵敏度高，特异性不强（就是说只要发现异常的能力较好，但是异常有可能是生理正常的现象所致），分辨率较低 CT：CT为无创性检查，检查方便、快捷。 密度分辨力高，密度相差很小的不同组织通过窗技术就能能被区分(提供2000Hu左右)。 CT能提供横断面图象，并可进行...
CT是X线计算机断层成像，优点是扫描速度快（几秒钟），对骨骼和肺组织分辨率高，检测费用较低。缺点主要...

PET检查，大医院核医学科可以做，是目前诊断肿瘤最灵敏的检查了，而且是全身性的，要几千块钱。它是要把显像剂从静脉注入人体，然后在仪器下显像，早期的没有发生形态学改变的病灶也能够显示，这是CT和MRI无法做到的。还有一种更昂贵的，叫PET-CT，是把PET和CT图像结合取来，取两者优点，比PET图像...

虽然MRI和PET/CT Scan有助诊断癌症,但MRI检查期间,会产生噪音,可能会对人造成困扰和不安,而且空间受限,或会对幽闭恐惧症患者造成压力;而PET/ CT Scan毕竟带有辐射,不建议普通人以此作全身检查,除非已确诊癌症,或是具有家族遗传癌症病历的人士,才适宜在医生介绍下接受相关放射诊断。 定期身体检查的确是可有助预防和...
