The procedures were performed on a Siemens Artis Q.zen biplane system with high-sensitivity detectors allowing low-dose imaging. Good radiological practice, e.g. adapting dose level and frame rate continuously and minimizing the x-ray field with collimators, was routine during procedures. The median total dose-area-product (DAP) value was 58 \u03bcGym2 for diagnostic catheterizations, 48 \u03bcGym2 for interventional catheterizations and 33 \u03bcGym2 for myocardial biopsies. The median DAP per body weight was 4.0 \u03bcGym2 kg\u22121. The median total fluoroscopy time varied from 6.0\u00a0min for myocardial biopsies, to 9.7 and 10.5\u00a0min, respectively, for diagnostic and interventional catheterizations. The third quartile of the DAP values in each weight group was proposed as LDRL. LDRLs for fluoroscopy time were determined solely based on procedure type, due to the absence of weight dependence.<\/jats:p>","DOI":"10.1093\/rpd\/ncab072","type":"journal-article","created":{"date-parts":[[2021,5,19]],"date-time":"2021-05-19T19:26:37Z","timestamp":1621452397000},"page":"279-288","source":"Crossref","is-referenced-by-count":11,"title":["DOSE EVALUATION AND PROPOSAL OF LOCAL DIAGNOSTIC REFERENCE LEVELS FOR PAEDIATRIC CARDIAC CATHETERIZATIONS PERFORMED ON A HIGH-SENSITIVITY ANGIOGRAPHIC SYSTEM ALLOWING LOW-DOSE IMAGING"],"prefix":"10.1093","volume":"195","author":[{"given":"Maria","family":"Hultenmo","sequence":"first","affiliation":[{"name":"Department of Medical Physics and Biomedical Engineering, Sahlgrenska University Hospital, SE-413 45 Gothenburg, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anders","family":"Nygren","sequence":"additional","affiliation":[{"name":"Pediatric Heart Center, The Queen Silvia Children\u2019s Hospital, Sahlgrenska University Hospital, SE-413 45 Gothenburg, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bj\u00f6rn","family":"S\u00f6derberg","sequence":"additional","affiliation":[{"name":"Pediatric Heart Center, The Queen Silvia Children\u2019s Hospital, Sahlgrenska University Hospital, SE-413 45 Gothenburg, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H\u00e5kan","family":"W\u00e5hlander","sequence":"additional","affiliation":[{"name":"Pediatric Heart Center, The Queen Silvia Children\u2019s Hospital, Sahlgrenska University Hospital, SE-413 45 Gothenburg, Sweden"},{"name":"Department of Pediatrics, Institute of clinical sciences, The Sahlgrenska Academy, University of Gothenburg, SE-413 45 Gothenburg, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2021,6,9]]},"reference":[{"key":"2021101213362914100_ref1","article-title":"The 2007 recommendations of the International Commission on Radiological Protection","author":"International Commission on Radiological Protection","year":"37 (2\u20134)","journal-title":"Ann.
