Technique for neurosurgically relevant CT image transfers using inexpensive video digital technology

Abstract

OBJECTIVE To examine and document neurosurgically relevant CT image transfers using inexpensive video digital technology. METHODS Thirty abnormal CT scans were evaluated on a personal computer monitor following their digital image creation and transfer by electronic mail (e-mail). These were compared with the radiologist’s interpretation of a hard copy of the CT scan originals. Any change in diagnosis based on the CT scan or e-mail image was assessed after completion of the comparison. RESULTS A total of 30 CT scans were successfully transferred and reviewed. On only one image was there disagreement between the neurosurgeon’s and the radiologist’s interpretations of the image. This resulted in a change in the radiologist’s diagnosis after digital image transfer occurred and the neurosurgeon diagnosed an isodense subdural hematoma, which was later confirmed at the time of surgical decompression. CONCLUSIONS A hand-held, inexpensive digital camera may serve neurosurgeons as a helpful alternative to expensive, labor-intensive teleradiology systems. It should be considered as an adjunctive option for small community-based hospitals unable to financially support more sophisticated teleradiology techniques, which have been shown to provide a significant benefit in the management and outcome of head trauma patients.
