Audit Of Radiation Dose Received By Pregnant Woman During CT Pelvimetry At Tertiary Care Hospital, Peshawar

AIMS AND OBJECTIVE(S):

Background: Pelvimetry assesses the size of a woman’s pelvis aiming to predict whether she will be able to give birth vaginally or not. This can be done by clinical examination, or by conventional X‐rays, computerised tomography (CT) scanning, or magnetic resonance imaging (MRI).

The aims and objective of the study is:

To audit radiation dose received by pregnant patient during CT Pelvimetry at tertiary care hospital Peshawar.

Method:

This was a pilot study carried out at Northwest General Hospital, Peshawar. This was study of 6 months with a population of 53 pregnant patients. Data was collected by prospective and retrospective study and analyzed by SPSS version 22.

Result:

The final study population includes 53 pregnant patients coming to NWGH for CT pelvimetry. The effective dose received by the patients was ranging from 0.425 to 0.650 mSv. The mean of radiation dose and total dose is 0.72 and 1.58 respectively.

Conclusion:

The pilot study conducted demonstrates technique of CT pelvimetry and the radiation dose protocol as currently performed. In this study effective dose received by pregnant patients in mSv is ranging from 0.425 to 0.650 mSv. Even though the technique currently used, operator need to reduce kVp and mAs need to be lowered to reduce patient radiation dose.
