What can ct plain scan detect

I believe that many times when you go to the hospital to see a doctor, the doctor will recommend that the patient do a CT scan. Some patients do not want to do a CT scan because it is not only expensive, but also emits relatively large amounts of radiation to the human body, which can cause a lot of harm to the human body. So what can a plain scan reveal when doing a CT scan? Let me give you a detailed introduction below!

Head examination can show the gray matter and white matter of brain tissue, the ventricular system and the subarachnoid space, and can directly show changes such as brain tumors, cerebral hemorrhage, and cerebral infarction; lung examination can clearly show the fine texture of the lungs; it can clearly show the shape, outline and lesions of organs such as the liver, spleen, pancreas, kidneys, and adrenal glands

It is suitable for the detection of neoplasms in various parts of the body, the localization diagnosis of small tumors, the distribution range, infiltration and metastasis of tumors, and biopsy under CT guidance; it is suitable for the detection of inflammation in most parts of the body and the determination of its range, such as inflammation in the brain, orbits, sinuses, mediastinum, liver (bacterial or protozoan inflammation or abscesses), pancreas and bones; it is suitable for the detection and qualitative diagnosis of large vessel lesions (vascular malformations, hemangiomas, vascular occlusions and bleeding) in various parts of the body; it has important quantitative and qualitative value in determining the bleeding from trauma to important organs, is also very valuable in locating various foreign bodies from trauma, and is very sensitive to the detection of calcification or stones in certain parts of the body. CT is also suitable for the detection of certain organ degeneration or congenital abnormalities, such as fatty degeneration of the liver and congenital abnormalities of the central nervous system.

The whole abdominal CT scan contains a lot of information, but CT has a great impact on the body! There is a risk of cancer. It is recommended that you do less or even no CT scans:

Research by the International Commission on Radiological Protection (ICRP) has confirmed that a full-body CT scan will increase the risk of radiation-induced cancer in the examinee by about 8%. Radiation-induced cancer and hereditary diseases are dose-linear and have no threshold, which means that the more exposure, the greater the possibility of developing fatal cancer and hereditary diseases. Moreover, the younger you are, the more sensitive you are to X-rays, and the greater the radiation damage caused! There is a risk of cancer in the long term! Therefore, infants and children should avoid exposure to X-rays as much as possible, and especially avoid CT examinations, because this is a type of examination with the highest dose and radiation among current medical X-ray examinations, so try not to do it! At present, the abuse of CT examination is common. Patients undergo CT examinations as soon as they have the slightest problem. Some people even have several examinations in a month. This not only causes economic waste, but also may cause radiation damage. There is a risk of cancer!

Therefore, both medical staff and the general public should learn some knowledge about radiation protection. The indications for CT examination should be strictly controlled. If non-radiation methods (such as ultrasound, MRI, colonoscopy, gastroscopy, etc.) can be used, then non-radiation methods should be used. If the problem can be solved by X-ray, then CT examination should not be used. Particularly women of childbearing age, pregnant women and infants should avoid CT examinations as much as possible. Take preventive measures to reduce the harm caused by radiation to humans

The epithelial cells of the ovaries, pelvis, and intestines in the abdomen are very sensitive to X-rays and can be easily damaged! Moreover, the dose of abdominal CT is large and the damage is also great! It may even affect offspring and skipped generations. Therefore, it is best not to do a CT scan!
