CT scan vs. MRI quick comparison of differences Picture: A medical technician prepares a patient for an MRI to check for a possible brain tumor CT scans utilize X-rays to produce images of the inside of the body while MRI (magnetic resonance imaging) uses powerful magnetic fields and radiofr...
MRI vs. CT Scan CT Scans|MRI MRI and CT scans have several differences, though your doctor uses both for imaging. Find out why your doctor may recommend one over the other and how they differ. What sets these scans apart is critical in choosing the right one for diagnosis. Discover 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...
Here MRIs have a certain edge over CT scans in the quality of details. Unlike CT scans, MRIs do not use radiation, but they are somewhat noisy, slower, and claustrophobic, which may cause anxiety. Besides, because of their strong magnets MRIs may not be safe for some candidates including ...
CT Scan vs MRI for Back Pain 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...

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...
The Paradox of MRIs and CT Scans in Diagnosing Pain Have you ever wondered if an MRI or CT scan can pinpoint exactly where your pain originates? It’s a common question with a surprising answer: often, the answer is no. Here’s why understanding the capabilities and limitations of these...
It depends. Both machines have their advantages and disadvantages. A lot of the deciding factor about which to use will boil down to the type of injury you have, as well as preference. Advantages of CT Scans Patients who have metal fragments or devices can use a CT scan because no magneti...
正电子扫描(PET Scan)可显示细胞新陈代谢的情况,追踪早期癌细胞病变,电脑扫描(CT Scan)则可提供体内器官及肿瘤准确位置,两者结合可以检查病灶的形态、大小和新陈代谢率,有助于鉴别肿瘤。 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...
