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...
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...
A CT scan is better than an MRI for the imaging of calcified tissues, like bones. CT scans produce excellent detail used to diagnose osteoarthritis and fractures. Also, patients with metal or certain medical implants cannot undergo MRIs due to the magnetic field pulse. However, CT scans can b...
