A patient dose survey for femoral arteriogram diagnostic radiographic examinations using a dose-area product meter.
We present a method for dealing with a complex radiographic procedure (which involves multiple radiographs and fluoroscopy) in an attempt to provide a simple way of calculating effective dose from which a general risk factor can be determined. A useful index of harm can be obtained by recording the number of radiographs in each region, and the fluoroscopy time, from which the effective dose may be easily calculated. A patient dose survey was carried out using a PTW diamentor for femoral arteriogram procedures in a large teaching hospital. The procedure involves fluoroscopy to the pelvic region to locate a guide wire and catheter, followed by a series of radiographs extending from the pelvic area to the feet to form a collage image of the entire arterial system. Radiographs are taken whilst a bolus of contrast media is injected into the arterial system. These measurements extend a continuing survey of doses for common diagnostic radiographic examinations which have previously included the simple examinations of lumbar spine, abdomen and pelvis.
