Electron beam CT

Electron beam CT (ultra-fast CT) uses electron beams to penetrate the human body and rapid bed movement to complete the scan. Its fastest scanning speed is 50ms/layer. Overall, it is superior to spiral CT scans. The main scanning range is larger than spiral CT in unit time. The artifacts generated by movement are less than that of spiral scan. The imaging of cardiovascular contrast is better than that of spiral scan, but this expensive equipment is still rare in China. Basic Information Specialist Category: Cardiovascular Examination Category: CT Applicable gender: whether men and women apply fasting: not fasting Tips: severe liver and kidney dysfunction, severe thyroid disease, acute pancreatitis; acute thrombophlebitis; multiple myeloma and other heterogeneous proteinemia, severe cachexia patients are banned. Normal value There was no abnormality in the angiography. Clinical significance Abnormal results can be examined by angiography to understand the occurrence and development of coronary atherosclerosis, and can also compare the effects before and after drug treatment. The person in need of examination has a patient with cardiovascular disease. Precautions Before the test: The patient must carry relevant examination data, including CT, MRI and routine X-ray examination data, as well as other clinical examination data.

Iodine allergy tests must be performed on patients who need to be augmented. Explain to the patient: Eliminate fear and make the patient cooperate with the examination. 2, the choice of scanning conditions: including body position, layer thickness and layer spacing, scanning parameters and scanning methods. Not suitable for the crowd Unsuitable people: severe liver and kidney dysfunction, severe thyroid disease, acute pancreatitis; acute thrombophlebitis; multiple myeloma and other heterogeneous proteinemia, severe cachexia.
