Is enhanced CT scan for gastric cancer harmful to the body? Pay attention to these four points

The main harm of enhanced CT scan for gastric cancer to the body includes nausea and vomiting, shock and death in severe cases, and a certain degree of radiation, so it is important to do an iodine allergy test before the examination. Also, it is important to fast before enhanced CT scan and drink plenty of water to facilitate better examination. Surgery is the main treatment for gastric cancer, and other treatments include radiotherapy, chemotherapy, and traditional Chinese medicine.

CT scans are familiar to everyone. Generally, they are used for better examinations and disease tests. Although there is some radiation, it is relatively small. As long as you are not pregnant, you can generally do it. Some patients with gastric cancer also need enhanced CT scans, but they are also worried about the impact on their health. Do you want to know if enhanced CT scans for gastric cancer are harmful to the body?
The hazards of enhanced CT examination for gastric cancer patients mainly include the following aspects:
1. The contrast agent used before enhanced CT examination is mostly iodine contrast agent, which can cause nausea, vomiting, and even shock and death. Therefore, an iodine allergy test should be performed before the examination to prevent allergic reactions.
2. Both ordinary CT scans and enhanced CT scans will produce certain radiation to the human body and should be used under the guidance of a doctor. However, enhanced CT scans are safe within the effective dose range. For some special populations, such as pregnant women and children, X-ray and CT scans are not recommended. Ultrasound and magnetic resonance imaging are used instead.
The following preparations should be made before enhanced CT scan of gastric cancer:
1. Fasting is required before enhanced CT scan: if you eat before enhanced CT scan, food residues may be misdiagnosed as gastric masses. In addition, this can also reduce the impact of gastric motility on the examination.
2. Drink plenty of water before enhanced CT examination: In order to better perform the examination, you can drink water to stimulate your appetite. Because water has a uniform density, it is a good control agent. Therefore, patients should pay attention to drinking plenty of water before the examination.
Gastric cancer is generally treated through surgery. If radical surgery is used, it is necessary to pay attention to the conditions that there is no obvious distant metastasis. The radical surgery measures for gastric cancer are different at different stages. Early gastric resection is good, but gastric lymph node dissection should be performed. Palliative gastrectomy or gastrojejunostomy is performed if the main lesions in the middle stage cannot be removed. Therefore, all aspects should be checked during surgical treatment.
