Teaching people bad habits…

I had a CT scan taken last month and my GP wanted to have a look at the images himself, so I stopped by the hospital this morning to ask for a copy.

The young lady at the medical imaging front desk just needed my name and data of birth (not what I’d call strict authentication… [1]). A couple minutes later I had a still-warm CD in hand, so obviously the first thing I did at home is to plop it into my computer’s drive.

A quick look at the files doesn’t promise much good: Autorun.inf and friends. Plopping it into a Windows system (with autorun enabled) confirmed things: it runs some application that just copies some information to disk and then launches the image viewing application…

While this may be convenient I would expect anyone who has a professional need to deal with such information to already have a DICOM image viewer installed and WIBNI vendors of devices that create and manage these images did the right thing and not teach doctors to run applications from questionable sources [2].

[1] Unless she has X-Ray Vision and compared me to the images she had on-screen?
[2] Say, a patient. The hospital’s logo printed on the CD is hardly an unforgeable indication of origin.

    HI Bart,
    Here, you would have had to sign a release stating that the information was being given to you, and that you were responsible for its security from the time it was handed over. Radiologists who read these images from the PACS are using much different software than the DICOM viewer. When you burn the image to a CD or DVD, though, you are dependent on the viewer. Unfortunately there are a number of DICOM viewers and even different flavors of DICOM, so not everything plays nicely with everything else, hence the tendency to embed the viewer in the CD with the file that belongs to it. We have not yet found a DICOM viewer that can reliably open any DICOM file we throw at it. WIBNI there was one! We have given the doctors in our region access to our Phillps PACS through a browser, and that has virtually eliminated the need to burn CDs. So, your GP could have connected (securely) via the Internet and viewed the image from a reliable source while knowing that it hadn’t been altered. This was a large project, though . . .
