Thank you very much Surdi for your reply. By searching for someone in this field of knowledge… I appreciate very much you input. The topic though is “Remove hearing aids before panoramic dental x-ray.”
So as far as I understand from the productmanager from Signia he says “Tests are done with the hearing aids and X-rays with a power of 100kV/100mGy. More than 100kV can potentially damage the chips”.
You can assure this also, thats fine. But unfortunately you do not give any specification. So what is your opinion about the specified kV and mGy as that is the important detail missing.
I have been an academical radiologist myself and started on MRI and CT’s at the very beginning. So I have some basic knowledge, as a radiation expert, about X-rays, ultrasound and magnetic resonance, but not about memory modules in HA’s.
Of course, as you also state, magnetic metal in an MRI is not allowed! Thats why every MRI institute will ask questions like did you work in metalindustrie or are you aware of metal- implants which could be even tatoo- ink, and makeup for camouflage of skintumors or even makeup for whatsoever reason and so on!. And these can even lead to faildiagnoses even in x- ray examinations.
The kV used by panoramic dental x-rays is not in the range of 100kV and over. So the question for me stays what about the low kV in panoramic dental x-rays specific. That will be about 70kV… Maybe you can give some information about that I hope.
About your question “Why take the risk ? Why fixated on keeping your aids in during any such procedure ?” Sometimes patients arrive in the x- Ray dept. in f.i. emergency cases or you want to give them instructions during an examination they have to hear you. So my perspective is a bit different then that of the patient I can have a good conversation with. Nowadays there are HA’s wich are in the canal and not easily visible anymore in a fast inspection. And most of the time we have to ask a patient more than just if he wears HA’s. Thats why I am personaly so persistent in knowing exactly what is important to not damage HA’s.
