Imaging Breakthrough "Sees" Lung Disease 114

Roland Piquepaille writes "According to BusinessWeek, an Israeli startup, aptly named Deep Breeze, has developed a high-tech replacement for the 200-year-old stethoscope. This noninvasive device can draw, in seconds, an image of your lungs by listening to its vibrations. The Vibration Response Imaging (VRI) system could already be used in Israel, Europe and South Korea. Last month, the US Food and Drug Administration approved its introduction in the US. But don't expect to see one of these systems used by your local physician anytime soon. This VRI system will carry a price tag of over $40K."

When there are unusual sounds that require additional insight, then you break out the one VRI that is available in the physician's group. It would be similar to how most cardiac auscultation is straightforward, but when there is something particularly unusual, you send a person for an echo cardiogram.

    TFA says that the price of the imaging modality will drop in the next few years with economies of scale and so forth. This is good, very good. It means that it'll make its way into the GP's practice soon and not just be in the hands of respiratory physicians and hospitals. But, honestly, look at things like this: TFA mentions that as far as replacing the stethoscope goes, it removes any sort of interpersonal bias between doctors in diagnosis. While this is just wonderful in respect to some esoteric diagnoses ie. whether you can *hear* a tiny small-cell carcinoma, but for the rest of us, I feel that a stethoscope, a quiet room and a competent doctor will suffice. The sounds of pneumonia, emphysema, pulmonary oedema, tuberculosis, bronchiole asthma etc. are all quite distinctive and as a medical student, I find it somewhat surprising that there can be any significant argument or doubt regarding the diagnosis of such patients. Heck, even if there was doubt, there are other elements of the presenting complaint (risk factors, family history, blood tests and plain old signs & symptoms) that can help doctors reach a definitive diagnosis. What I'm trying to say is, the old stuff works, its tried and true, and it's not easy to honestly miss pulmonary lesions. So, apart from being a novel visual toy (I know it's an instrument but how much fun is this?!) would it HONESTLY replace a $70 stethoscope and a head full of juicy knowledge brains? Me thinks nah :-p
    • Yes...and then?

      I agree, it won't replace the stethoscope, but there is only so much a stethoscope can do. This is another tool to add to the set, and it appears to be a very interesting and useful one at that. Think of all the other ways to get an image of the lungs...none are even remotely as cheap as this.

      So no, it won't replace the stethoscope...but the stethoscope also won't stand in the way of this being adopted. Rather, I expect they will become complimentary tools.
  • ...Daredevil, machine without peer.

  • So the thingy seems to have an array of microphones that sure look like stethoscope heads. They are replacing one stethoscope plus a trained physician's brain (making a mental image out of various sounds in various places) by many mikes and a computer to show the image. A good evolutionary change there, I'd say.

Happiness is a positive cash flow.
