“…Furthermore, medical staff may also be exposed to a considerable amount of scatter radiation while standing next to patients during interventions [16 -19]. Rathmann et al analyzed the absolute radiation dose values received by medical staff during a total of 131 CT-guided interventions using thermoluminescent dosimetry data [18]. The authors concluded that radiologists had a low overall level of whole-body radiation exposure (mean: 0.022 mSv per procedure; max: 0.164 mSv).…”

Interventional Radiology 906Chang DH et al. Ergebnisse: Es gab keine signifikanten Unterschiede bezüglich der diagnostischen Akzeptanz und der Komplikationsrate in beiden Gruppen. Im Vergleich zu SDCT erreichte LDCT eine Dosisreduktion im Median um 68,6 %. Die Implementation der iterativen Rekonstruktion war bezüglich der Rauschunterdrückung und der subjektiven Bildqualität der FBP überlegen. Bezüglich der Aufhärtungsartefakte ergab sich kein Unterschied zwischen beiden Gruppen. Schlussfolgerung: Das LDCT-Protokoll erzielt eine signifikante Reduktion der Strahlenexposition um mehr als 2/3, während die diagnostische Sicherheit und Präzision beibehalten werden. Die iterative Rekonstruktion ist, aus der Analyse der objektiven und subjektiven Auswertung der Bildqualität zu bevorzugen. Kernaussagen:▶ Niedrigdosisprotokolle (LDCT) sind bei CT-gesteuerten Interventionen an der Lunge bezüg-Abstract ! Purpose: To compare the radiation doses and image qualities of computed tomography (CT)-guided interventions using a standard-dose CT (SDCT) protocol with filtered back projection and a lowdose CT (LDCT) protocol with both filtered back projection and iterative reconstruction. Materials and Methods: Image quality and radiation doses (dose-length product and CT dose index) were retrospectively reviewed for 130 patients who underwent CT-guided lung interventions. SDCT at 120 kVp and automatic mA modulation and LDCT at 100 kVp and a fixed exposure were each performed for 65 patients. Image quality was objectively evaluated as the contrast-to-noise ratio and subjectively by two radiologists for noise impression, sharpness, artifacts and diagnostic acceptability on a four-point scale.Results: The groups did not significantly differ in terms of diagnostic acceptability and complication rate. LDCT yielded a median 68.6 % reduction in the radiation dose relative to SDCT. In the LDCT group, iterative reconstruction was superior to filtered back projection in terms of noise reduction and subjective image quality. The groups did not differ in terms of beam hardening artifacts. Conclusion: LDCT was feasible for all procedures and yielded a more than two-thirds reduction in radiation exposure while maintaining overall diagnostic acceptability, safety and precision. The iterative reconstruction algorithm is preferable according to the objective and subjective image quality analyses.

“…While the aforementioned campaign efforts are primarily targeted at decreasing patient exposure, operator and medical staff exposure is a concern with interventional procedures (10,11). Given the increasing complexity of interventional procedures and the subsequent increase in fluoroscopy time, operator safety is paramount.…”

O ver the past decade there has been an increase in scrutiny pertaining to radiation dose associated with medical procedures from both professional societies and the lay press. In 2006, a total of 4 million interventional procedures performed in the United States accounted for approximately 14% of the collective radiation dose from radiological procedures (1). In the same year, an estimated 67 million CT scans performed in the United States accounted for approximately 49% of the collective radiation dose from radiological procedures (1). Together, interventional radiology procedures and CT scans accounted for approximately 71 million examinations. In contrast, approximately 293 million diagnostic radiographic and fluoroscopic studies were performed in the United States in 2006 (1), but only accounted for approximately 11% of collective dose. Due to the disproportionate amount of ionizing radiation contributed by both interventional procedures and computed tomography examinations, dose reduction in these two modalities has become a particular focus of attention for professional societies and providers alike (2, 3).Technical advances coupled with the increased interest in reducing radiation dose from medical procedures have resulted in a steady increase in the number of contributions to the radiological literature pertaining to radiation dose reduction over the past decade. Scientific contributions and educational sessions focusing exclusively on dose reduction have become fixtures at national and international radiology meetings. The aim of the current study is to quantify this increased interest and awareness by performing a systematic analysis of I N T E R V E N T I O N A L R A D I O LO G Y O R I G I N A L A R T I C L E PURPOSEWe aimed to quantify and compare awareness regarding radiation dose reduction within the interventional radiology and diagnostic radiology communities. METHODSAbstracts accepted to the annual meetings of the Society of Interventional Radiology (SIR), the Cardiovascular and Interventional Radiological Society of Europe (CIRSE), the Radiological Society of North America (RSNA), and the European Congress of Radiology (ECR) between 2005 and 2015 were analyzed using the search terms "interventional/computed tomography" and "radiation dose/radiation dose reduction. " A PubMed query using the above-mentioned search terms for the years of 2005-2015 was performed. RESULTSBetween 2005 and 2015, a total of 14 520 abstracts (mean, 660±297 abstracts) and 80 614 abstracts (mean, 3664±1025 abstracts) were presented at interventional and diagnostic radiology meetings, respectively. Significantly fewer abstracts related to radiation dose were presented at the interventional radiology meetings compared with the diagnostic radiology meetings (162 abstracts [1% of total] vs. 2706 [3% of total]; P < 0.001). On average 15±7 interventional radiology abstracts (range, 6-27) and 246±105 diagnostic radiology abstracts (range, 112-389) pertaining to radiation dose were presented at each meeting.
