Is there radiation involved in the equipment used for cardiac angiography and stent placement?

The X-ray equipment used during cardiac angiography emits radiation; however, the radiation dose is strictly calculated by professionals and controlled within a relatively safe range. This radiation exposure is one-time and has minimal impact on the human body in the short term. Furthermore, the devices used for stent placement procedures generally do not emit radiation, so there is no need for excessive concern. In addition, modern medical technology has implemented a series of measures to reduce radiation risks, including assessing the patient's radiosensitivity before the procedure and taking appropriate protective measures. Therefore, overall, the equipment used in cardiac angiography and stent placement procedures is relatively safe in terms of radiation exposure. Patients undergoing these procedures should maintain a positive mindset and follow the doctor's instructions to ensure the safety and success of the procedure.
