How to Measure/Calculate Radiation Dose in Patients?

Abstract: Patients in fluoroscopically guided interventions (FGI) may be exposed to substantial radiation dose levels (SRDL). The most commonly reported adverse reactions are skin injuries with erythema or necrosis. It is therefore important for the interventional radiologist to know deterministic effects with their threshold doses. If possible all relevant modality parameters should be displayed on the interventionalists screen. Dosimetric parameters should be displayed in digital imaging and communications in medicine… Show more

“…Nevertheless, for patients a limit on cumulative dose of radiological procedures is not recommended. However, the radiation dose of a single radiological procedure must be warranted within reasonable thresholds [20,21]. As shown in figure 3, the more vessels were treated in one session, the higher the calculated DRLs.…”

“…This approach has been encouraged for several years in Europe in accordance with the European Directive 2013/59/EURATOM (EU-BSS) [13]. The European Society of Interventional Radiology is also involved in this process [14][15][16][17][18][19]. Beyond the simple optimisation of acquisition parameters, this study underlines the major role of medical physics experts in interventional radiology, their relationship with interventional radiologists, and the importance of educating radiology technologists.…”

“…The image quality of the guided acquisitions was considered insufficient for 23% of the patients by the operator. The radiology technologists had to increase the settings by 16 mA [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] during this phase to obtain the expected resolution (figure 4). For the control phase, the required parameters were used for only 48% of the procedures.…”

“…The following data of patients undergoing TAVI procedures were recorded: demographics including age, sex, and BMI; dosimetry measurement (number of exposure images); air kerma-area product value (P KA , in Gy/cm 2 ); cumulative air kerma at the patient entrance reference point (K a,r , in Gy); and total fluoroscopy time (in min) obtained from the examination dose report in the structured radiation report, which is saved in the equipment upon process completion. 14 Aortic stenosis is the most prevalent form of valvular heart disease worldwide and its prevalence continues to increase. 1 As a treatment approach for aortic stenosis, transcatheter aortic valve implantation (TAVI) plays an important role in patients at high risk for surgical aortic valve replacement.…”
