When it comes to medical scanners, a common question is what the difference is between a CT and PET scan. NeuroLogica breaks down the technology.
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...
