ABSTRACT
AIM: The aim of this work was to examine the diagnostic reference levels (DRLs) for the abdomen-pelvis computed tomography (CT) examinations performed at our medical institution. Another aim was to compare our data with the national and international values for the same examination as starting point on the way of establishing a regional DRLs and to contribute to the national DRLs project.
MATERIALS AND METHODS: Dosimetric indexes were collected for the abdominal pelvic examination for 180 patients and results are analyzed using Matlab (R2016b) statistics and machine learning toolbox.
RESULTS: The results are within and below the international
reported levels for abdomen-pelvis CT in several countries and slightly higher than our published national reference level.
CONCLUSION: Continuous monitoring of the radiation doses received by the patients in computed tomography is a continuous and ongoing process in order to ensure compliance and to optimize clinical imaging protocols. More extensive data acquisition and analysis are required to allow a better understanding of the contributing factors leading to less patient radiation dose while preserving the
Adequate understanding of radiopharmaceutical distribution in the body of the patient has both spatial and temporal characteristics and they are the key factor to consider when planning successful…
Introduction: The purpose of the present work was to evaluate the imaging characteristics of 89Zr-PET in comparison with those obtained using fluorine-18 Fluorodeoxyglucose (18F-FDG) PET (a gold…
