BACKGROUND A suspicion of ventriculo-peritoneal shunt failure is classified as the most common indication for CT in children with hydrocephalus. The main target of the study was to evaluate the diagnostic value of a low-dose protocol and to compare a total DLP received by patients in compared protocols. MATERIAL/METHODS Our retrospective analysis included 256 examinations performed in patient...

The concept of diagnostic reference range (DRR) is introduced to address the balance between a patient’s risk (radiation dose) and benefit (image quality necessary for an accurate diagnosis). R provides minimum estimated dose that covers 25–75% distribution. International Commission on Radiological Protection, ICRP (2017) recommended 75th percentile as upper d 25th lower limit DRR [1]. Dose bel...

Introduction: The Diagnostic reference levels (DRLs) play a critical role in the optimization of radiation dose especially, in some conditions like pediatrics. They are useful indicators by which the radiologists can be aware of delivered excess radiation doses to the patients, and take corrective actions if necessary. In order to meet some requirements for establishing the nat...

There are 90 CT units operating in Serbia, with tenfold increase in the last decade, resulting with annual total of approximately 350000 procedures. The objective of this paper is to assess typical patient dose from adult and paediatric CT examinations. Initially, three hospitals (two general hospitals performing examination of adults and a dedicated paediatric hospital) were enrolled into the ...

OBJECTIVE Our aim in this study was to determine the relationship between chest circumference and the radiation doses received by breast tissues during Dual-Source Computed Tomography (DSCT) cardiac scans. MATERIALS AND METHODS Routine cardiac DSCT examinations with similar exposure lengths were applied to 30 female patients. The scanogram image, multi-slice helical scan x-ray tube voltage an...
