CT does not cause a decrease in platelet levels; possible causes of platelet level decreases include disease factors, drug factors, and environmental factors.
There is a very small amount of ionizing radiation associated with CT, and there are strict exposure times for CT. This short, low-dose exposure to ionizing radiation has very little effect on hematopoiesis and does not usually result in a decrease in platelet levels. There is no need to resist screening measures for this reason.
There are many causes of platelet lowering, and some primary thrombocytopenia may be related to auto-factors such as immunity, the mechanism of which is not yet fully understood.
For secondary thrombocytopenia, it may be related to disease factors such as tumor, leukemia, infection, etc., or the use of drugs such as chlorosulfopropamide, anagrelide, linezolid, estrogen, imatinib, etc., or environmental factors such as arsenic-mercury exposure and strong ionizing radiation.
It is recommended to go to the hospital in time when there is a decrease in platelet level.
