What is an effective way to reduce patient exposure dose levels during IVR procedures?

First, try exposure dose reduction methods such as selecting pulsed fluoroscopy with a low pulse rate, inserting an additional filter, positioning the detector (FPD) as close to the patient as possible, selecting an appropriate exposure field size, and reducing the irradiation field. In addition, it is also important to know about how much dose reduction is provided by each of those methods. The importance of using fluoroscopy or radiography depends on the given IVR procedure. For example, catheters and wires with good X-ray visibility are used for ablation, so that exposure dose levels can be reduced by decreasing X-ray emission parameters. Both fluoroscopy and radiography are often used in IVR procedures for lesions in the coronary artery, which requires being careful to switch OFF fluoroscopy whenever it is not being used and minimize the duration of radiography (reference material: 10 Key Points for Protecting Patients During X-Ray Fluoroscopy).
