Background/Introduction

Radiation dose monitorisation is becoming mainstay concern of radiology departments. For radiation reduction purpose hospitals determine strategies in accordance with international standards and guidelines. Radiation dose is also an important problem for countries since carcinogenic and genetic effects as sitocastic effects may constitute a significant health problem with long-term results regarding oncologic and non-oncologic disorders. Reduction of radiation dose in a country begins with monitorisation of radiation dose in nation-wide scale. Substantial variations exist in practice between some CT centres for similar types of examination...

Description of activity and work performed

Ministry of Health in Turkey has a project that deals with connecting nation-wide hospitals in terms of monitoring health centers through their healthcare service such as radiation dose recording. The aim of this project is to collect data from 647 hospitals in the country and compare the radiation doses of each type of CT examination between hospitals. Comparison results are assumed to be helpful to determine the mean national dose levels for each type of CT examinations (such as head, chest CT, etc.). In this...

Conclusion and Recommendations

Our results enabled us to be aware of dose variation in different hospitals from different regions of our country Mean DLP values for head, neck, chest and pelvis CT examinations were recorded by including 80.000 examination in the study. Our results revealed that maximum dose variations occurred in chest and pelvis CT examinations. There were few hospitals which had abnormally high dose levels compared to other hospitals. Detection of this abnormality made us to reorganize CT protocols in aforementioned hospitals Nation-wide PACS enables to monitor...
