OBJECTIVE Despite the obligatory recording of doses administered to patients during CT scans, this data is not easily accessible. The objective of this study was to implement and validate a computerised automated dose-recording system for CT scans, for a single radiology department. MATERIAL AND METHODS Every patient undergoing a CT scan in our department over a one-year period was included i...

BACKGROUND To investigate the radiation dose and image quality for iterative reconstruction combined with the CARE kV technique in chest computed tomography (CT) scanning for physical examination. METHODS A total of 130 patients who underwent chest CT scanning were randomly chosen and the quality reference value was set as 80 mAs. The scanning scheme was set and the patients were randomly div...

Purpose Analysis of patient´s X-ray exposure during percutaneous radiologic gastrostomies (PRG) in a larger population. Materials and Methods Data of primary successful PRG-procedures, performed between 2004 and 2015 in 146 patients, were analyzed regarding the exposition to X-ray. Dose-area-product (DAP), dose-length-product (DLP) respectively, and fluoroscopy time (FT) were correlated with th...

OBJECTIVE. The objective of this study was to optimize CT protocols for whole-body PET/CT by reducing radiation dose while minimizing effects on image quality. MATERIALS AND METHODS. Before protocol optimization, a survey of 140 consecutive patients was conducted to establish the baseline dose from a whole-body PET/CT examination. Another sample of 100 patients was surveyed to evaluate the redu...
