ABSTRACT
Purpose: The aim was to observe and manage the patient radiation dose in CT
Methodology: A retrospective study of observation and management of patient radiation dose in CT was conducted for 5 months. During this period patient radiation dose was observed. CTDI and DLP were calculated. Patients were divided in three age groups (0-15 yrs, 16-55 yrs, 56-85 yrs) on the basis of pre-reproductive, reproductive & post-reproductive age. All the age groups were compared on the basis of dose received. Radiation dose was also compared in different body parts.
Result: A study was conducted in the department of radiology at SGT hospital for observation and management of the patient radiation dose in CT. Total 84 patients were taken in this study. Out of which 50 (59.5%) were males and 34 (40.4%) were females. In the age group of 0-15 yrs DLP was high in abdomen 772.47 mGy.cm and low in chest 234.22 mGy.cm. In the age group of 16-55 yrs DLP was high in head (809.51 mGy.cm) and low in neck (380.27 mGy.cm) and in the age group of 56-85 yrs DLP was high in head (923.63 mGy.cm) and low in chest (477.51 mGy.cm). Among all the age groups head dose was high in the age group of 56-85 yrs, neck dose was high in the age group of 56-85 yrs, chest dose was high in the age group of 16-55 yrs and abdomen dose was high in the age group of 56-85 yrs. The overall radiation dose was high in the age group of 56-85 yrs (37%) and less in the age group of 0-15 yrs (30%). It was observed that radiographers uses lead apron to cover the area of patient which is outside the ROI to protect the patient from unnecessary radiation dose. They always keep in mind that the centering of patient should be correct. They also avoid repeated exposure to the patient.
Conclusion: In this study, it was found that in head, neck and abdomen dose was high in the age group of 56-85 yrs and chest dose was high in the age group of 16-55 yrs. The overall radiation dose was high in the age group of 56-85 yrs which was 37% and lowest radiation dose was in the age group of 0-15 yrs which was 30%. It was observed that radiographers uses radiation protection devices to cover the area of patient which is not needed to be examine, to protect the patient from unnecessary radiation dose. They do the proper centering of patient. They also avoid repeated exposure to the patients. It is suggested to give less radiation dose to the patient.
