Firstly, new general guidelines and working models optimising the radiation dose and image quality are needed.. Secondly, the challenge derived from the first one is to update the competence of the staff working with imaging units and to train the new health care personnel so that their competence could match the needs of the new technique.

Research paper thumbnail of Radiation exposure to patients during endoscopic retrograde cholangiopancreatography: A multicentre study in Finland

The available data about patient radiation doses in ERCP show a large variation that needs to be further investigated. The aim of this study was to determine the radiation doses to patients during ERCP, evaluate the risk of radiation-induced injury and to calculate the effective dose (ED) in patients who underwent an ERCP procedure. Methods A multicentre study which included ten hospitals was carried out in Finland. A total of 227 patient radiation doses in ERCP were recorded during a 4-month period in 2012. Entrance surface dose (ESD) was estimated by using thermoluminescent dosimeters (TLD) implemented in one of the hospitals. ED was calculated from dose area product (DAP) measurements. The data were analysed with the IBM SPSS Statistics version 21 (2012) software. Results The patient radiation doses in ERCP varied significantly in this study. The mean DAP was 5.15 (0.08–57.00) Gy cm², fluoroscopy time 2.4 (0.03–22.2) min and the number of X-ray images was 2.5 (0–14). A strong linear correlation was observed between the DAP and fluoroscopy time. The average ESD and ED in ERCP was 10 mGy and 1 mSv, respectively. Conclusion Patients received a greater radiation dose in therapeutic ERCP compared to diagnostic ERCP. The increase in frequency and complexity of ERCP procedures indicates the possibility of an increase in radiation exposure to patient. The results suggest that efforts at optimization and dose reduction in ERCP should be made.

The article focuses on how radiographers’ role in eHealth and teleradiology is described in the published studies. Materials and methods: In this systematic review data was searched from Finnish and English language electronic health care databases and from the Thesis database of universities of applied sciences. Also volumes of the Journal of Digital Imaging were reviewed. No time limit was set because the phenomenon is relatively new. Inclusion criterion was that the selected studies described radiographers in an active role or as beneficiary. Studies describing radiographers’ role in diagnostic or therapeutic teleradiology were searched. Studies comprising final data were analyzed by inductive content analysis. Results: Most central areas forming radiographers’ role in Teleradiology and eHealth were a) patient information management - working at the RIS/PACS-surface, b) imaging or giving ...

Research paper thumbnail of Quality assurance in digital dental imaging: a systematic review

However, dental radiography accounts for nearly one third of the total number of radiological examinations in the European Union. Therefore, special attention is needed with regard to radiation protection. In order to lower patient doses, the staff performing dental examinations must have competence in imaging as well as in radiation protection issues. This paper presents a systematic review about the core competencies needed by the healthcare staff in performing digital dental radiological imaging quality assurance. Materials and methods. The following databases were searched: Pubmed, Cinahl, Pro Quest and IEEXplore digital library. Also volumes of some dental imaging journals and doctoral theses of the Finnish universities educating dentists were searched. The search was performed using both MeSH terms and keywords using the option 'search all text'. The original keywords were: dental imaging, digital, x-ray, panoramic, quality, assurance, competence, competency, skills, knowledge, radiographer, radiologist technician, dentist, oral hygienist, radiation protection and their Finnish synonyms. Results. Core competencies needed by the healthcare staff performing digital dental radiological imaging quality assurance described in the selected studies were: management of dental imaging equipment, competence in image quality and factors associated with it, dose optimization and quality assurance. Conclusions. In the future there will be higher doses in dental imaging due to increasing use of CBCT and digital imaging. The staff performing dental imaging must have competence in dental imaging quality assurance issues found in this review. They also have to practice ethical radiation safety culture in clinical practice.
