1, PETCT: an imaging device that reflects the genetic, molecular, metabolic and functional state of the lesion.
2. Thermal CT: from infrared technology of foreign military to medical functional imaging technology in medical application field.
Second, the advantages are different.
1 and the advantages of PETCT:
(1)PET uses positron nuclide as tracer, and the function and metabolic state of the lesion can be known by taking tracer from the lesion site. It can show the pathophysiological characteristics of the whole body, such as organ function and metabolism. It's easier to find the lesion.
(2)CT can accurately locate the focus and show the subtle structural changes of the focus; PET/CT fusion images can comprehensively detect the lesions, accurately locate and judge the benign and malignant lesions, and can detect the lesions early, quickly, accurately and comprehensively.
(3)PET is like a navigation mark in the sea, and CT is like a nautical chart, which can find the target accurately and quickly.
2. Advantages of thermal CT:
(1) Sensitivity: Early and early detection of cancer is possible due to the change of cellular metabolism of thermal tomography imaging-locked thermal body.
(2) Uniqueness: thermal tomography imaging is an excellent supplement to the lack of evaluation methods in sub-health/subclinical state, overall human environment and early detection of serious diseases.
(3) comprehensiveness: It is difficult for traditional clinical diagnostic techniques to obtain comprehensive information of a person in one examination. Thermal tomography can instantly obtain the whole body information, including circulatory, respiratory, digestive and reproductive systems; From tumors, cardiovascular and cerebrovascular diseases to local inflammation or pain.
(4) Safety: It is absolutely safe to passively receive the thermal radiation generated by human cell metabolism during thermal tomography imaging detection, so that the human body can detect without radiation, interference, contact and damage.
(5) Motivation: With the help of the safety and simplicity of thermal tomography, we can review and evaluate the changes of health status, the effect of health care methods or the development of disease course indefinitely and dynamically at any time.
Extended data:
Thermal CT is different from ordinary infrared thermal scanning technology, and it can only get the heat distribution law on the human surface. The energy information inside the human body overlaps with the energy information on the surface of the human body. It is difficult for clinicians to analyze and identify the health information in the human body.
Thermal CT imaging is to find out the relationship between the heat distribution on the surface of human body and the depth of heat source through thermoelectric analogy, so as to obtain the information of the depth, radiation value, shape and change of heat source inside human body and evaluate the health status of human body. According to the corresponding relationship between the metabolic intensity of human cells and diseases. Simply put, the relationship between ordinary infrared technology and thermal tomography imaging is just like the relationship between ordinary X-ray and ct.
