Thread: MRI images on CD?

  1. #1

    MRI images on CD?

    I got a copy of my last MRI images on CD. I was a bit dissapointed by the resolution, I was expecting more. The images are only 256x256, on my 19" monitor that looks like a thumbnail. How can a doctor diagnose anything from such low res images?

    I don't know for sure how to read these, but I was told my C7 was crushed, I also cracked C1, C2 and C4. I'm C8/T1 complete. Counting down the vertebrae it looks like the break in my spinal cord is between C5 and C6 though.

    Learn from the mistakes of others, you won't live long enough to make all of them yourself.

    jimnms, what program are you using to open the files and how big are they? Wise.

    Yeah really, I know where you are coming from. Anyone know where to get a hi-res MRI, or are MRI's limited to sub-VGA resolution for a slice that represents a fairly large area being scanned? My film version of my MRI is pretty much the same, small pic of big area.

    STUDY DESIGN:: A magnetic resonance imaging technique that enables indirect detection of neuronal activity has been developed for the spinal cord. In the present study, this method, spinal functional magnetic resonance imaging (fMRI), is applied to the first study of the injured spinal cord, with the goal of better clinical assessment of the entire cord. OBJECTIVES:: The objectives of this project are: (1) to investigate the neuronal activity that can be detected in the spinal cord caudal to a chronic injury by means of spinal fMRI, and (2) to develop spinal fMRI as a clinical diagnostic tool. SETTING:: Institute for Biodiagnostics, National Research Council of Canada, Winnipeg, Manitoba, Canada. METHODS:: fMRI of the spinal cord was carried out in 27 volunteers with cervical or thoracic spinal cord injuries (SCIs). Of these volunteers, 18 had complete injuries, and nine had incomplete injuries. Spinal fMRI was carried out in a 1.5 T clinical MR system, using established methods. Thermal stimulation at 10 degrees C was applied to the fourth lumbar dermatome on each leg, and images were obtained of the entire lumbar spinal cord. RESULTS:: Areas of neuronal activity were consistently observed in the lumbar spinal cord in response to the thermal stimulation, even when the subjects had no awareness of the sensation. The pattern of activity was notably different compared with noninjured subjects. In general, subjects with complete SCI showed absent or diminished dorsal gray matter activity, but had enhanced ventral activity, particularly contralateral to the stimulation. CONCLUSIONS:: Spinal fMRI is able to provide a noninvasive assessment of the injured spinal cord that does not depend on the patient's perception of the stimulus being applied. This work was carried out on a standard clinical MRI system without modification, and so is readily applicable in most MR units. SPONSORSHIP:: This work was funded by a grant from the Canadian Institutes of Health Research (CIHR).Spinal Cord (2004) 42, 59-66. doi:10.1038/

    It's called CDRS Image Viewer, but all it does it load up in Internet Explorer. The files it opens from the CD do not have an extension. It starts witih SC000001, then MR000002, MR000003, etc. The files are 137kb. The program allows you to export them to .bmp files. One of the files is 512x512 (SC000001), but the rest are 256x256.

    I don't know alot about the different files, but I save photo files as jpg and have a scanner program that allows them to be resized as big or small as necessary. Can you resize the files? I'm not sure but 137 kb doesn't sound very large.
