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...
Radiation does not stay in the body with a CT scan: After a CT scan, no radiation remains in the body. On the contrary, a small amount of radiation may stay in the body for a short time after a PET scan. PET scans detect cancer earlier than other tests: Unlike other forms of imagi...
PET-CT scanner for standard CT only imaging exams as well. The CT scan anatomical imaging can be fused with the nuclear PET imaging to show anatomical landmarks. The CT component can also be used in cardiac PET to perform a coronary calcium scoring exam to offer a risk assessment for ...
导读:pet-ct scan images即pet-ct扫描图像,具有将pet图像与ct图像融合的功能, 病人在检查时经过快速的全身扫描,可以同时获得CT解剖图像和PET功能代谢图像,使医生在了解生物代谢信息的同时获得**的解剖定位,从而对疾病做出全面、**的判断。那么,pet-ct scan images能诊断什么病?pet-ct检查前需要注意什么?
1. Positron Emission Tomography (PET) CT Scan The PET CT scan helps the physician to see the level of activity of certain body organs and tissues, along with their structure. You’ll receive a substance called a “tracer” containing glucose with a little bit of radioactive material attached...
