@a.saji - It looks like a straightforward piece of diagnostic equipment and if it is able to be used in family practice offices, I am betting it will be a lot cheaper than the equipment required for a PET scan. If they can market it to family practices, volume sales will surely help drive the cost down as well - just my opinion.

Elizabeth, I am guessing what Daniyal_Ali is referring to is that as symptoms progess and worsen, more drastic measures are required. Think of something like cholesterol levels - when caught early - dietary changes, exercise and low doses of a drug (or none at all) will often control it sufficiently. But if a person has had undetected high cholesterol for a longer period of time, plaque may have had a greater chance to develop requiring some sort of medical intervention, and cholesterol levels may have progressed to being much higher than if detected and addressed earlier. This would require higher levels of medication and perhaps different ones since the body has a greater threat to deal with. Or like glaucoma - detecting it early may mean it can be controlled with medicine but if allowed to progress without being diagnosed means that a different approach will be needed involving both medicine and perhaps surgical intervention. I think dosage is a key factor and the risk of side effects always increase as dosage increases. Progressed disease can also call for more powerful drugs which may also have more powerful side effects.

Thanks for your comment, Nancy. Yes, it is an awesome achievement. I hope FDA approval comes swiftly to use this machine! What a breakthrough for those dealing with this terrible disease.

Good point, Daniyal_Ali, about focusing more on a good diagnostic device and less harsh medication. But I have a question--what is the connection between early diagnosis and more mild drugs? Wouldn't the drugs required to cure or stymie the disease be the same no matter when it's detected?

Yes, Jack B, you've hit on the two key points of this invention and why it's so great--early detection and something that is not so invasive for the patient and can be done fairly easily in a doctor's office.

a.saji, not sure of the cost but I can check with the company. I think it may be too early to say since it's not totally in use yet.

@Nancy: Indeed it is. Any idea of the cost ?

Being able to replace injecting a patient with a radioactive tracer isotope to do a PET scan with a simple eye ointment and scan sounds like an awesome achievement - and to be able to bring it to the level of family practice even more so. This is a very exciting development.

I agree Jack. Dragging the diagnosis to a point where the drugs and medicine could work effectively should be the ultimate goal when curing any illness. I wonder why the researchers focus more on making strong drugs instead of making a good diagnostic device that could cure the disease using mild drugs.
This device is not only unique but also very helpful as it would allow starting the treatment before the life-threatening symptoms begin.
