CT radiation dose in children: a survey to establish age-based diagnostic reference levels in Switzerland
This work aimed at assessing the doses delivered in Switzerland to paediatric patients during computed tomography (CT) examinations of the brain, chest and abdomen, and at establishing diagnostic
Iterative reconstruction methods in two different MDCT scanners: physical metrics and 4-alternative forced-choice detectability experiments--a phantom approach.
TLDR
VEO clearly confirms the tremendous potential of iterative reconstructions for dose reduction in CT and appears to be an important tool for patient follow-up, especially for pediatric patients where cumulative lifetime dose still remains high.
Patient doses in CT examinations in Switzerland: implementation of national diagnostic reference levels.
TLDR
Results showed large variations in doses between different radiology departments in Switzerland, especially for examinations of the petrous bone, pelvis, lower limbs and heart, indicating that the concept of DRLs has not yet been correctly applied for CT examinations in clinical routine.
Using 80 kVp versus 120 kVp in perfusion CT measurement of regional cerebral blood flow.
TLDR
It is concluded that 80 kVp acquisition of perfusion CT studies of r CBF will result in increased contrast enhancement and should improve rCBF analysis, with a reduced patient's irradiation.
Aortoiliac and lower extremity arteries assessed with 16-detector row CT angiography: prospective comparison with digital subtraction angiography.
TLDR
Sixteen-detector row CT angiography is an accurate and reliable noninvasive alternative to conventional DSA in the assessment of aortoiliac and lower extremity arteries in patients with peripheral arterial disease.
Radiation protection in digestive endoscopy: European Society of Digestive Endoscopy (ESGE) guideline.
This article expresses the current view of the European Society of Gastrointestinal Endoscopy (ESGE) about radiation protection for endoscopic procedures, in particular endoscopic retrograde
Brain perfusion in children: evolution with age assessed by quantitative perfusion computed tomography.
TLDR
Specific age-related evolution patterns were identified in the different anatomic areas of the cerebral parenchyma, which could be related to the development of neuroanatomic structures and to the emergence of corresponding cognitive functions.
How to set up and apply reference levels in fluoroscopy at a national level
TLDR
A nationwide survey was launched to investigate the use of fluoroscopy and establish national reference levels (RL) for dose-intensive procedures, and a wide variability was found for several types of examinations, mainly complex ones.
Semiautomatic mammographic parenchymal patterns classification using multiple statistical features.
TLDR
The proposed semiautomatic classifiers method provides an objective and reproducible method for characterizing breast density, especially for the two-class case.
Quality initiatives* radiation risk: what you should know to tell your patient.
TLDR
The basic principles of radiation protection need to be respected to help counteract the unjustified explosion in the number of procedures being performed and the concept of diagnostic reference levels should be used to reduce variations in practice among institutions and to promote optimal dose indicator ranges for specific imaging protocols.
