Radiation from CT is metabolized within 1.5 days after the exam. The ionizing radiation produced by CT examination is transient and does not remain in the patient’s body, and can be metabolized within 1.5 days after the CT examination. Due to the fast scanning speed and short irradiation time per unit time of CT, the dose of contrast agent used is small and the utilization rate of contrast agent is high, which ensures the high efficiency of the examination and greatly reduces the damage to the patient at the same time. Although CT examination is very helpful for the diagnosis of the disease, but it is not recommended to carry out CT examination frequently, so as not to cause unnecessary damage to the body. In the meantime, you can drink more water, eat more fresh fruits and vegetables and protein-rich foods to enhance your body’s metabolism after the test. When a CT test is needed to help diagnose a disease, it should be performed according to the doctor’s instructions, and it is not recommended to perform CT tests frequently to avoid the accumulation of radiation in the body, which may affect the health of the body.
