In this report, the Commission recommends approaches to national authorities for their definition of scope radiological protection control measures through regulations, by using its principles justification and optimisation. The report provides advice deciding radiation exposure situations that should be covered relevant regulations because regulatory can justified, and, conversely, those may considered exclusion from is deemed unamenable unjustified. It also on resulting regulated...
Fenestrated endovascular repair of abdominal aortic aneurysms has been proposed as an alternative to open surgery for juxtarenal and pararenal aneurysms. At present, the evidence base this procedure is predominantly limited single-center or single-operator series. The aim study was present nationwide early results fenestrated in United Kingdom.All patients who underwent between January 2007 December 2010 at experienced institutions Kingdom(>10 procedures) were retrospectively studied by use...
The growth of image-guided procedures in surgical settings has led to an increased need interact with digital images under sterile conditions. Traditional touch-based interaction techniques present challenges for managing asepsis these environments leading suggestions that new touchless may provide a compelling set alternatives. In this paper we explore the potential Interventional Radiology (IR) through ethnographic study. findings highlight how distribution labour and spatial practices...
The International Commission on Radiological Protection (ICRP) has embarked a review and revision of the system that will update 2007 general recommendations in ICRPPublication 103. This is beginning process take several years, involving open transparent engagement with organisations individuals around world. While robust performed well, it must adapt to address changes science society remain fit for purpose. aim this paper encourage discussions which areas might gain greatest benefit from...

Abstract Background Endovascular stent-grafting is an established option for the repair of abdominal aortic aneurysm (AAA) that can involve prolonged manipulation under radiological control. The aim was to determine average radiation exposure sustained during endovascular (EVAR) and first year postoperative surveillance. Methods Prospective dose data were recorded used calculate area product (DAP) values 96 patients undergoing EVAR. DAP then entrance skin (ESD), indicator potential damage,...
Objective. Takayasu arteritis (TAK) and giant cell (GCA) are 2 major variants of large vessel vasculitis (LVV). The frequent involvement vessels in GCA has raised the possibility that TAK should be regarded as 1 disease. By detailed phenotyping a single-center cohort, we aimed to define differences between GCA. Methods. Forty-five patients (23 TAK, 22 GCA) were identified. Baseline characteristics, clinical symptoms, laboratory data, enhanced computed tomography/magnetic resonance imaging,...
Background: Cardiopulmonary exercise testing (CPET) is the gold-standard for quantification of peak oxygen uptake (VO 2 ) and cardiorespiratory muscle responses to exercise. Its application Duchenne muscular dystrophy (DMD) has been scarce due notion that weakness inherent disease restricts system from reaching maximal capacity. Objective: To investigate utility CPET in DMD by 1) establishing whether patients can perform maximal-effort valid VO assessment; 2) quantifying repeatability; 3)...
La Commission internationale de protection radiologique (CIPR) a initié un examen et une révision du système radioprotection afin mettre à jour les recommandations générales 2007 dans la Publication 103 CIPR. Il s’agit début d’un processus plusieurs années qui nécessite collaboration ouverte transparente avec organismes personnes monde entier. Bien que le soit robuste efficace, il convient l’adapter l’évolution des connaissances scientifiques société demeurer adapté aux besoins. Le présent...
Many pregnant women are exposed to radiation either as a patient or an employee. Ignorance of the issues surrounding exposure females is encountered among medical and other professionals, often leading undue concern. The patients has be justified risk/benefit carefully assessed. Diagnostic radiological nuclear medicine procedures do not usually pose increased risk fetus but therapeutic radiotherapy may so. Risks greatest during organogenesis first trimester. Informed consent counseling...
OBJECTIVES: With increasing experience, endovascular aortic aneurysm repair (EVAR) has been extended to patients with less suitable aorto-iliac anatomy in an attempt reduce peri-operative mortality. However, more complex EVAR procedures may take longer and can result higher rates of complications, additional interventional frequent radiological imaging, which offset some the benefit. This study determined radiation burden for standard EVAR, as by EVAR-1 trial criteria, EVAR. METHODS: A total...
1. After simultaneous intravenous injection as a mixture, 99mTc-labelled diethylenetriaminepentaacetic acid (99mTc-DTPA; molecular mass 492 Da) and inulin (∼6000 gave arterial plasma clearance curves consisting of three exponentials, the time courses which were not significantly different between two solutes. 2. The ratio 99mTc-DTPA to inuiin concentration in antecubital venous (normalized at 30 s) was 0.6, less than unity, within 2 min after injection, but increased reach unity by 60 min....
Purpose: To evaluate the midterm feasibility, efficacy and safety of internal iliac artery branch grafts for endovascular repair aortoiliac, common iliac, aneurysms. Methods: Between December 2006 September 2008, 8 patients underwent elective Computed tomography aortography (CTA) was used to detect postoperative endoleak, stent migration, patency, aneurysm sac expansion. Results: All were correctly implanted. However, intraoperative occlusion occurred in 2 cases. Both occlusions have been...
