Abstract
In pediatric interventional cardiology, cardiologists need to stay closer to the patient than during adult catheterization, and the use of biplane systems increases the scatter radiation. Occupational radiation risk is rather high, and estimation of lens doses becomes necessary. Deriving factors for assessing these doses from the patient doses displayed in catheterization laboratories can help in preserving staff radiation safety. A biplane X-ray system and polymethylmethacrylate plates of 4 to 20 cm to simulate pediatric patients have been used. Patient entrance dose rates, dose-area product, and doses to the eyes of the cardiologists for the typical operation modes have been measured. Correlations between patient and staff doses have been obtained. Scatter dose rates increase by a factor of 92 from low fluoroscopy to cine acquisition when phantom thickness increases from 4 to 20 cm. Scatter doses increase linearly with dose-area product for all the thicknesses. Administration of 1 Gy·cm2 to the patient involves 7 μSv to the eyes of the cardiologist (without extra protection). In conclusion, the experimental correlation factors found between phantom and scatter doses allow a fairly good estimation of staff doses from the dosimetric patient data.

Purpose: To report estimated radiation doses to the eye lens of the interventionalist from procedures performed with and without use of radiation protection measures. Materials and Methods: Scattered radiation doses for seven interventional radiology fluoroscopic systems were measured by using phantoms simulating patients 16–28 cm in thickness undergoing low-, medium-, and high-mode fluoroscopy, cine cardiac imaging, and digital subtraction angiography (DSA). The radiation doses to the eye lens ...

Mean patient dose area products (DAP) in invasive cardiology are high and for specific interventional procedures vary greatly. For this reason patients may face serious radiation injuries and an increased risk of cancer in the future. Such increased risk is due less to inappropriate equipment than to inadequate operational technique and a lack of awareness of the potential for injury by individual cardiac interventionists. This article focuses on the “as low as reasonably achievable” (ALARA) pri...

In interventional cardiac procedures, staff operates near the patient in a non-uniformly scattered radiation field. Consequently, workers may receive, over a period, relatively high radiation doses. The measurement of individual doses to personnel becomes critical due to the use of protective devices and, as a consequence of the large number of methods proposed to assess the effective dose, great variability in monitoring programmes is expected among European countries. SENTINEL consortium has c...

Abstract—Cardiac catheterization procedures using fluoroscopy reduce patient morbidity and mortality compared to operative procedures. These diagnostic and therapeutic procedures require radiation exposure to patients and physicians. The objectives of the present investigation were to provide a syst

Infants and children are a higher risk population for radiation cancer induction compared to adults. Although some values on pediatric patient doses for cardiac procedures have been reported, data to determine reference levels are scarce, especially when compared to those available for adults in diagnostic and therapeutic procedures. The aim of this study is to make a new contribution to the scarce published data in pediatric cardiac procedures and help in the determination of future dose refere...

: Computed tomography (CT) technology has changed considerably in recent years with the introduction of increasing numbers of multiple detector arrays. There are several parameters specific to multi-detector computed tomography (MDCT) scanners that increase or decrease patient dose systematically compared to older single detector computed tomography (SDCT) scanners. This document briefly reviews the MDCT technology, radiation dose in MDCT, including differences from SDCT and factors that affect ...

Patient and staff dose values in an interventional cardiology laboratory for different operational modes and several patient thicknesses (from 16 to 28 cm, simulated using polymethylmethacrylate) are presented. When increasing patient thicknesses and depending on fluoroscopy and cine modes, occupational doses can increase >30 times the baseline level. Scatter dose rates at the cardiologist's position with no radiation protective tools ranged from 1 to 14 mSv h -1 for fluoroscopy, and from 10 to ...

This report describes occupational radiation doses of interventional cardiologists over 15 years and assesses action undertaken to optimize radiation protection. Personal dosimetry records of nine staff cardiologists and eight interventional cardiology fellows were recorded using personal dosemeters worn over and under their lead aprons. The hospital in which this study was conducted currently performs 5000 cardiology procedures per year. The hospital has improved its facilities since 1989, when...

Abstract Mandatory eye lens monitoring for exposed workers who are liable to receive an equivalent dose to the lens of the eye higher than 15 mSv in one year, required by the new European Basic Safety Standard 2013/59 and the recommendation given by the International Commission on Radiological Protection to lower the annual dose limit for the lens of the eye to 20 mSv, have put dosimetry services using Panasonic dosemeters in a difficult position. There are no commercially available eye lens dos...

The aim of the study was to estimate organ dose rate reduction to a female anthropomorphic phantom, which simulated the cardiologist, during percutaneous coronary interventions (PCI) when the patient's arm support was covered with 0.4-mm lead foil. Organ dose rates were determined using five radiation detectors inserted into the left eye, left thyroid, left breast, left liver lobe and uterus of the phantom. A male anthropomorphic phantom was placed on the examination table of an angiography syst...

Background We previously showed that using the radial artery access site as opposed to the femoral artery site decreases the radiation exposure of patients during coronary artery interventions. The objective of this study was to compare radiation exposure levels of the operating physician during coronary interventions when incorporating both radial and femoral artery approaches.

Coronary angiography is a widely available diagnostic and therapeutic modality. Radiation exposure is set to increase as a result of greater complexity of coronary and structural cases now being undertaken. Therefore all cardiologists need to be aware of not only the risks of radiation but also strategies to minimize radiation exposure for both patients and catheter laboratory staff.
