digital radiography newsAccording to the research showed at the American Heart Association's Scientific Sessions this year,a protocol that uses in a regular way real-time radiation monitoring, low-dose screening systems and needed doctor awareness of radiation dose, obviously the reduction of radiation expousre during the electrophysiology procedures and catheter ablations to detect and cure heart arrhythmias in children.

Invasive cardiac electrophysiology is used to detect and cure abnormal heart rhythms, or arrhythmias, which can range from the benign to the life-threatening. In the study, researchers looked at boys and girls at an average age of 14.5 years who subjected to electrophysiology procedures to detect and cure arrhythmias. In the procedures, physicians use fluoroscopy, which is a regular X-ray, to guide catheters in the heart which are inserted through blood vessels in the groin or neck that lead to the heart.

Akash R. Patel, M.D., lead author of the study and an electrophysiology fellow in the Division of Cardiology at The Children's Hospital of Philadelphia in Pa.mentioned that "Radiation exposure in pediatric electrophysiology procedures is not insignificant. We compared the radiation exposure of 70 children who had undergone the procedures before we began the protocol to that of 61 children who had the procedures after we instituted the protocol."

The recent protocol uses a less dose fluoroscopy setting and continuous real-time monitoring of radiation exposure. When the radiation dose registers at specific levels, the doctor is noted so that the he or she can moderate the fluoroscopy cameras to minimize exposure. Obviously,the researching team discovered that decreased radiation exposure among children whose procedures were formed using the recent protocol, involving 22 % reduction in the time that the X-ray machine was on ,52 % reduction in the dose of X-ray entering the skin, which helps to prevent skin injury ,51 % reduction in median effective dose, which correlates with the lifetime raised risk of cancer from radiation exposure.

Patel reported "While we did not measure what these lower doses mean in the long run, we presume, for example, that reducing the effective dose will decrease the child's lifetime increased cancer risk from radiation exposure, The public should be aware of radiation exposure from electrophysiology procedures, and physicians and hospitals should be vigilant in implementing protocols aimed at reducing radiation exposure from these procedures. This is especially important in children to minimize their risk of radiation-induced cancer because they should live for many decades after their procedures."
