“…This large range in radiation dose has been corroborated recently in other studies [15], with technical and procedural variation between clinical specialist centres being identified as one of the main contributors to dose variation during IC procedures [16]. At present, no guidelines have been published detailing standard radiographic protocols for paediatric IC; however, image quality criteria has been effectively used for radiographic examinations previously [17,18]. Work by the Digital Imaging Measures for Optimising Radiological Information Content and Dose Cardiology Group (DIMOND III) set criteria for cardiac images as guidelines on how an angiogram should appear using reliable techniques [19,20].…”

An analysis of radiation dose reduction in paediatric interventional cardiology by altering frame rate and use of the anti-scatter grid

The purpose of this work is to investigate removal of the anti-scatter grid and alteration of the frame rate in paediatric interventional cardiology (IC) and assess the impact on radiation dose and image quality. Phantom based experimental studies were performed in a dedicated cardiac catheterisation suite to investigate variations in radiation dose and image quality, with various changes in imaging parameters. Phantom based experimental studies employing these variations in technique identified that radiation dose reductions of 28%–49% can be made to the patient with minimal loss of image quality in smaller sized patients. At present, there is no standard technique for carrying out paediatric IC in the UK or Ireland, resulting in the potential for a wide variation in radiation dose. Dose reductions to patients can be achieved with slight alterations to the imaging equipment with minimal compromise to the image quality. These simple modifications can be easily implemented in clinical practice in IC centres.

“…The first measurements using phantoms incorporating test objects were made by Burger (1949), followed by Hay, Davison and Dummling in the 1960s, as mentioned in Henshaw (1976). One of the main goals of an effective programme of quality control in radiodiagnostic facilities (Ghilardi Netto et al 1983, Vaño et al 1998, ICRU 1996, CEC 1996 should be the achievement of techniques producing high-quality images.…”

Optimization of standard patient radiographic images for chest, skull and pelvis exams in conventional x-ray equipment

et al. 2004

Optimized radiographic techniques for clinical images of chest, skull and pelvis using conventional single-phase, three-phase and high-frequency x-ray units for a standard patient have been developed. Optimization of image contrast and optical density was obtained by using a homogeneous phantom (PEP) and an Anderson Rando anthropomorphic phantom. Image quality was evaluated by nine radiologists in independent analyses, leading to the choice of the optimized technique. A course of action to implement and validate these techniques in other radiographic systems has also been introduced. A realistic-analytic phantom (RAP) was constructed to certify the validation process. The optimized radiographic technique was implemented in the routine of our home hospital radiodiagnostic routine, enabling a reduction in patient doses around 25, 14 and 72%, respectively, for chest, skull and pelvis exams when compared with the previously used techniques. In addition, a corresponding reduction in the x-ray tube load of 68, 14 and 62% for the respective mentioned exams has been observed. In conclusion, implemented optimal techniques can lead to a reduction in the rate of film rejection, thus contributing to a better risk-benefit relationship for the patient and cost-benefit for the radiodiagnostic facility.

Avoiding radiation injuries from interventional fluoroscopic procedures

After the alert of the FDA in 1994, about induced skin injuries to patients during fluoroscopically guided procedures, several national and international organizations addressed the topic to improve the safety in interventional radiology. The number and complexity of interventional procedures are increasing during the past years, but the number and rate of skin injuries is not known because no comprehensive monitoring or reporting mechanism exists. In interventional procedures, patient dosimetry is difficult, as X-ray entrance skin areas and different beam projections, field sizes, electronic magnification, radiation qualities, etc., are unpredictable. In addition, service engineers can modify parameters affecting dose and image quality tailoring the systems to the particular requirements of the users. This article reviews the reported skin injuries in the scientific literature. Misuse, X-ray system faults or non-optimized operational protocol gives rise sometimes to the injuries. The available procedures to evaluate patient doses and practical advice to minimize risks are also discussed.
