A recent survey conducted in the US has revealed that over half of the people that were undergoing medical scans such as X-Rays had no clue whether or not they were exposed to radiations and still had questions that remained unanswered even though they were on the verge of subjecting themselves to these tests.

The study authors wrote in the Journal of the American College of Radiology that several studies have already established that the more informed people are, the better decisions they make and the less anxiety they experience, all the while recording an increased satisfaction with their treatment.

Dr. Andrew Rosenkrantz, lead author, claims that although a large number of medical scans is performed yearly in the US, the majority of patients are not informed about what the tests entail and the possible dangers that might occur.

The study, in which 176 patients participated, focused on their knowledge of which medical scans involve radiation and which do not. They had to choose between CT, nuclear medicine scans, MRI and ultrasounds. The results were staggering, as only 46% of the people questioned correctly identified the tests which involved the use of radiation.

It appears that, although 78% of the participants claimed that the doctor explained the procedure they were about to undergo, only 72% understood the explanations. One in five patients had rather used the web to learn about the exam, or asked friends and family.

Although there are many benefits of medical testing, exposing yourself to radiation can potentially increase the risk of getting cancer, which is why the proper information of the public in this respect is crucial and there should be a better doctor-patient communication.

Patients are advised to seek answers from their doctors and not undergo such procedures until they know the whole picture - what they entail, the risks, or any possible alternatives, and not go through with it while still having unanswered questions. Patients may be subjecting themselves to major health risks without being aware of it and this lack of proper information can easily be avoided by discussing openly. #News
