Background: The purpose of this study is to estimate PSD indirectly using a Radiation Dose Structured Report (RDSR) from Cath lab interventional procedures. The estimated dose was then compared with direct measurements using films. Materials and Methods: Information on radiation exposure and dosage associated with a specific interventional radiology procedure is provided in the RDSR document. The RDSR produced by the machine was verified using slab phantom, Gafchromic XRV3 film, and Ray Safe X2 detector. The PSD is estimated by adding the intensely projected beam dose in acquisition mode with the fluoroscopic dose percentage obtained from the RDSR. During the procedure, Gafchromic films were used to measure PSD directly. Then, the estimated PSD was compared with the measured PSD. Result: The PSDmes and PSDcal in this study showed an average difference of 0.12 Gy (8%). The Wilcoxon Signed-Rank test has a p-value of 0.08 and the Spearman's rank correlation coefficient (rs) of 0.97 indicates a very strong positive correlation between the two variables. Conclusion: The Statistical analysis shows that the estimation of PSD using RDSR is reliable for monitoring the patient. This method may help the cardiologist to follow up of the patients to give extra care to skin reactions. A safe standard work practice will certainly monitor the prevention of undesirable consequences of radiation. |
