Over one million European children undergo computed tomography (CT) scans annually. Although moderate- to high-dose ionizing radiation exposure is an established risk factor for hematological malignancies, risks at CT examination dose levels remain uncertain. Here we followed up a multinational cohort (EPI-CT) of 948,174 individuals who underwent examinations before age 22 years in nine countries. Radiation doses the active bone marrow were estimated on basis body part scanned, patient...
Why was the cohort set up?Medical diagnostic examinations, although delivering low doses of ionizing radiation, are main man-made source radiation exposure for general population.The number procedures performed has grown dramatically in high-income countries recent decades. 1 Among
Computed tomography (CT) has great clinical utility and its usage increased dramatically over the years. Concerns have been raised, however, about health impacts of ionising radiation exposure from CTs, particularly in children, who a higher risk for some induced diseases. Direct estimation impact these exposures is needed, but conduct epidemiological studies paediatric CT populations poses number challenges which, if not addressed, could invalidate results.
The main aim of mammographic screening is to reduce the mortality from breast cancer. However, use ionizing radiation considered a potential harm due possible risk inducing cancer in healthy women.To estimate number radiation-induced cancers, deaths, and lives saved implementation organized as performed Norway.We used previously published excess absolute model which assumes linear no-threshold dose-response. estimates were calculated for 100,000 women aged 50-69 years, interval 2 with an...
The increasing worldwide use of paediatric computed tomography (CT) has led to concerns regarding the subsequent effects exposure radiation. In response this concern, international EPI-CT project was developed study risk cancer in a large multi-country cohort. radiation epidemiology, accurate estimates organ-specific doses are essential. EPI-CT, data collection is split into two time periods—before and after introduction Picture Archiving Communication System (PACS) introduced 1990s. Prior...
The diagnostic reference level (DRL) has generally been defined as the 75th percentile of distributions mean doses observed on a sample standard-sized patients, but for mammography, 95th used. In this study, and percentiles are estimated 26 full-field digital mammography units, representing six models from four manufacturers. Systematic differences between categories manufacture/models investigated with respect to glandular dose (MGD) figure merit (FOM), signal difference noise ratio squared...

The HARMONIC project (Health Effects of Cardiac Fluoroscopy and Modern Radiotherapy in Paediatrics) is a European study aiming to improve our understanding the long-term health risks from radiation exposures childhood early adulthood. Here, we present design for cardiac fluoroscopy component HARMONIC. A pooled cohort approximately 100 000 patients who underwent procedures Belgium, France, Germany, Italy, Norway, Spain or UK, while aged under 22 years, will be established hospital records...
In order to meet the future challenges posed by ageing populations, new technology, telemedicine and a more personalized healthcare system are needed. Earlier research has shown mobile radiography services be highly beneficial for nursing home residents in addition being cost-effective. Despite benefits, uncommon Europe Norway. The purpose of this study was explore success criteria barriers process implementing services, from point view hospital municipal managers. Eleven semi-structured...
Telemedicine applications, such as a mobile radiography service, provide new way of organizing healthcare services. In order to safe and personalised care for nursing home residents during X-ray examinations, services have been implemented. The objective this study was analyse the costs examinations treatments when comparing hospital-based imaging with combination service in Southeast Norway.A decision model developed using software TreeAge Pro. included two alternatives: alone. treatment...
The use of ionising radiation (IR) for medical diagnosis and treatment procedures has had a major impact on the survival paediatric patients. Although benefits these techniques lead to efficient health care, evaluation potential associated long-term effects is required. HARMONIC aims better understand increased risk cancer non-cancer after exposure IR in children with treated modern external beam radiotherapy (EBRT) – energy MeV range cardiac defects diagnosed fluoroscopy (CFP) keV range....

In the last decade, mobile radiography services have been introduced in nursing homes several countries. Earlier research found an underutilisation of diagnostic imaging among home residents. However, effects introducing on use are unknown. The purpose this study was to determine utilisation residents and if there any differences between hospitals with without a service. Data for 2015 were collected from radiological information systems 11 hospitals. data included anatomical...

Abstract Background Radiology professionals are frequently confronted with referrals containing insufficient clinical information, which hinders delivery of safe and quality medical imaging services. There is however lack knowledge on why how referral information important for radiographers in practice. This study explores what purposes used/ useful the radiographers, benefits involving them assessing referrals. Methods A cross sectional was conducted recruited through International Society...
