Effects of CT on newborns

CT is a common test method in people's daily life. CDs are mainly used to detect problems inside people's bodies and take some methods to treat them. I believe many people know that CT scans will have a certain impact on people's bodies. So what kind of harm will CT examination cause to newborn babies? Let us learn about the effects of CT on newborns through the following article.

Under normal circumstances, since CT is a radiation-based substance, it will cause more or less damage to the normally developing body and brain tissue.

At present, it is best not to do CT scans for babies. There is evidence that CT may affect the normal development of the body. However, considering the actual situation, it is not that serious, and the decision should be made based on the needs of the disease. When a CT scan is needed, the risk brought by CT is much smaller than the risk of brain disease. Therefore, at present, the benefits should outweigh the disadvantages. Don't think too much, and everything will be fine.

CT (Computed Tomography) is a computer tomography scan that uses precisely collimated X-ray beams, gamma rays, ultrasound, etc., together with extremely sensitive detectors to perform cross-sectional scans one after another around a certain part of the human body. It has the characteristics of fast scanning time and clear images, and can be used to detect a variety of diseases. According to the different rays used, it can be divided into: X-ray CT (X-CT), ultrasonic CT (UCT) and gamma-ray CT (γ-CT), etc.

Advantages

CT examination has high diagnostic value for central nervous system diseases and is widely used.

It has good diagnostic effect and is relatively reliable for intracranial tumors, abscesses and granulomas in several parts of the CT images, parasitic diseases, traumatic hematomas and brain injuries, cerebral infarction and cerebral hemorrhage, as well as intraspinal tumors and intervertebral disc herniation. Therefore, except for cerebral angiography which is still used to diagnose intracranial aneurysms, vascular dysplasia and cerebral vascular occlusion, as well as to understand the blood supply arteries of brain tumors, other brain X-rays such as pneumoencephalography and ventriculography are rarely used. Spiral CT scanning can obtain relatively detailed and clear vascular reconstruction images, namely CTA, and can achieve three-dimensional real-time display, which has the potential to replace conventional cerebral angiography.

CT is also valuable in diagnosing head and neck diseases. For example, it can detect orbital space-occupying lesions, early sinus cancer, small cholecystoma of the middle ear, destruction and dislocation of the auditory ossicles, minor destruction of the bony labyrinth of the inner ear, congenital malformations of the ear, and early detection of nasopharyngeal carcinoma. However, if the lesion is obvious and can be diagnosed by plain X-ray, CT examination is not necessary. In the diagnosis of chest diseases, CT examination is increasingly showing its superiority with the application of high-resolution CT. Contrast-enhanced scanning is usually used to determine whether there are masses or enlarged lymph nodes in the mediastinum and hilum, and whether the bronchi are narrowed or blocked. It is very helpful in diagnosing primary and metastatic mediastinal tumors, lymph node tuberculosis, central lung cancer, etc. Interstitial and solid lesions in the lungs can also be displayed better.

CT is more advantageous in showing areas that are difficult to display on plain film examinations, such as concentric and overlapping lesions of large vessels. Lesions of the pleura, diaphragm, and chest wall can also be clearly displayed. CT examination of the heart and great blood vessels, especially the latter, is of great significance. The heart aspect mainly focuses on the diagnosis of pericardial lesions. Display of cardiac chambers and walls. Since the scanning time is generally longer than the cardiac cycle, the image clarity is affected and the diagnostic value is limited. However, CT examination can well show calcification of coronary arteries and heart valves, calcification of large blood vessel walls, and aneurysm changes.

CT examination of abdominal and pelvic diseases is increasingly widely used, and is mainly used for the diagnosis of diseases of the liver, gallbladder, pancreas, spleen, peritoneal cavity and retroperitoneal space, as well as urinary and reproductive systems. Especially space-occupying lesions, inflammatory and traumatic lesions. CT examination is also of great value in detecting extraluminal invasion of gastrointestinal lesions and metastasis to adjacent and distant sites. Of course, the condition of gastrointestinal lesions still mainly depends on barium angiography, endoscopic examination and pathological biopsy. In most cases, bone and joint diseases can be diagnosed through simple and economical conventional X-ray examinations, so CT examinations are relatively rarely used.

shortcoming

The radiation dose is greater than that of ordinary X-ray machines, so pregnant women cannot undergo CT examinations.
