Patient Effective Dose profile in CATHLAB
Abstract
The intervention procedures are performed under fluoroscopic guidance and become increasingly common because of their obvious benefits to patients.Patient dose during cardiologic procedures is high due to lengthy procedure and the prolonged exposure time to the patient.Objective: The primary objective of the study was to evaluate the level of radiation dose received by the patients in order to estimate local diagnostic reference levels during cardiac catheterization procedures individually in terms of E (effective dose).Effective dose and doses to various organs estimated with the help of Monte Carlo PCXMC software.Material and Methods: A total of 123 patients were included in these studies, who were admitted to Cardiology department, and the data were collected retrospectively in a designed format during both diagnostic and therapeutic procedure.Results:The estimated patient dose rate as a whole in the Cath-Lab was found to be 96.45mGy/minwhich is considered lower than the recommended DRL (dose reference level) for the continuous high mode fluoroscopy used in interventional radiology (100mGy/min) given by IAEA.The effective dose was calculated and found respectively for CA-TFA, CA-TRA and CA-PTCA as 6.13mSv (range2.4-17.33),10.97mSv (range 5.56-29.03)and 34.68mSv (range 10.64-70.21).We observed strong correlation between total duration of procedure (both SCIREA Journal of Medicine http://www.scirea.org/
