Cost: CT scans are almost half the price of MRIs. The average computed tomography scan costs around $1,200 while an MRI is about $2,000. Speed: CT scans take much less time than MRIs. The exact time required depends on whether you need a contrast dye for the procedure, but MRIs alwa...
5. 3T MRI Scans Also known as the 3 Tesla MRI, the3T MRI scanis an efficient and powerful imaging exam that you may have instead of the 1.5T traditional scan. While 3T scanners were once only found mainly in medical research centers, these days, you may see them in clinical settings ...
MRI(磁共振造影),CT scan，概括性地说下这三者区别（包括优缺点）PET是核素扫描，需要注射同位素药物，...
A CT scan and MRI are both imaging machines used to help doctors see inside your body. For both of these tests, you’ll lie on a moving table that passes through a doughnut-shaped machine. A CT scan uses X-rays to image the body. An MRI uses radio waves and a powerful magnet to ...

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...

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...
