Local Diagnostic Reference Levels for Adult Computed Tomography Urography Exams

Area of Science:

• Medical Imaging
• Radiology
• Radiation Dosimetry

Background:

• Computed Tomography Urography (CTU) is crucial for diagnosing urinary tract diseases.
• CTU scans involve significant radiation exposure, raising patient safety concerns.
• Optimizing radiation doses in CTU is essential for minimizing risks.

Purpose of the Study:

• To analyze radiation doses (CTDIvol and DLP) in CTU examinations.
• To establish Local Diagnostic Reference Levels (LDRLs) for CTU in Bosnia and Herzegovina.
• To compare findings with European data and inform national guidelines.

Main Methods:

• Retrospective analysis of CTDIvol and DLP data from 203 adult CTU patients.
• Inclusion of patient demographics, examination phases, and clinical indications.
• Comparison with international scientific literature and European CTU dose data.

Main Results:

• Detailed analysis of radiation dose distribution in a large Bosnian and Herzegovinian patient cohort.
• Established LDRLs based on collected CTU dose data.
• Comparison highlighted variations and potential areas for protocol optimization.

Conclusions:

• The study provides crucial data for setting National Diagnostic Reference Levels (NDRLs) in Bosnia and Herzegovina.
• Established LDRLs serve as a benchmark for optimizing CTU protocols nationwide.
• This research contributes to enhancing patient safety through radiation dose management in medical imaging.
