CT brain, the full name is cranial CT, the scan area is usually the auditory orbital line (orbit to ear hole line) or the brain above the greater occipital foramen, ordinary plain scan can check the following problems: 1, congenital cranial developmental abnormalities: no/megalencephalic gyrus malformation, brain cleft malformation, corpus callosum developmental abnormalities, brain penetration malformation cyst, meningeal/brain expansion, etc. 2, hydrocephalus brain herniation. 3, brain atrophy brain swelling. 4, stroke: cerebral infarction and cerebral hemorrhage, etc. 5, cranial trauma (fracture, hematoma). 6, abnormal brain calcification, etc. In addition to ordinary plain scan, some diseases require enhanced CT examination to further understand the lesion blood supply and enhancement, which will add the procedures of contrast injection and multiple contrast scans, which can reveal the following issues: intracranial tumor extent, adjacent structures, blood supply, cysts, intracranial infections and other inflammatory lesions, etc. The 3D reconstruction of the imaging workstation can show the following problems in three dimensions: cerebrovascular diseases: aneurysms, arteriovenous malformations, arteriovenous fistulas, etc. (shown by vascular imaging CTA technology), tumors, fractures, bone defects in three dimensions (by multiplanar reconstruction MPR, surface reconstruction SSD, and volume reconstruction VRT, etc.), and also for 3D printing, surgical navigation, and AI recognition. Cranial CT, its price will vary according to the requirements of the price bureau in different provinces and cities, hospitals must strictly follow the requirements of the price bureau, can only charge less not a penny more, domestic is usually no operating doctor, diagnostic doctors and nurses labor value of the charge items, which is the reason why foreign CT examinations are dozens of times more expensive than domestic, this most valuable part can only be given away for free at no cost, which is considered to give domestic examiners According to the requirements of the price list, different types of CT is also different, spiral CT will be added than non-spiral CT spiral scanning fee (cost increased by hundreds of millions, the price only increased by more than 100 yuan), the price of different levels of hospitals will be slightly different, take the municipal tertiary hospitals, cranio-cerebral scan prices are in about two or three hundred yuan, but because of the differences in the specific items of the services provided by each hospital, the price is also somewhat Some hospitals provide 3D reconstruction services with additional charges. There are also some patients who need enhanced CT examinations to further understand the blood supply and reinforcement of the lesion, which will increase the cost of scanning, injection, and contrast agent.
