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 always...
CT scans are often used to find cancer, bone fractures, internal bleeding, blood clots, and injuries to the spine and brain. An MRI shows certain diseases that a CT scan can’t. For instance, uterine, prostate, and certainliver cancersare hard to see on a CT scan. Also, an MRI is u...

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...

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 ...
Patients with internal bleeding or other injuries would use a MRI scan to obtain the best detail. If a patient has a history of allergies, it may be best for them to use a MRI scan. Claustrophobic patients may be able to better tolerate a CT scan since it has a shorter duration. ...
