This study aims to determine the sensitivity of modern computed tomography (CT) scanners in detecting subarachnoid hemorrhage (SAH) and to determine whether there is a continued need for lumbar puncture to exclude the diagnosis. ⋯ CT scanning is excellent for diagnosing SAH. We demonstrate that in the first days after ictus a negative CT scan is sufficient to exclude SAH. Data do not allow for any specific cutoff point to be made. We suggest leaving out lumbar puncture in the first 3 days after ictus if the results of the CT scan are negative.

Advances in medicine have largely followed advances in technology. Medical strides have been made when physicians and researchers have adapted growing science to target specific problems. A new medical field, telemedicine, has emerged that links physicians with colleagues and patients. Cell phone technology is affordable for almost everyone, and basic models include digital photography. ⋯ This application of cell phone technology has been documented previously in the literature of other specialties and could attain greater stature as a legitimate method for close outpatient observation by neurosurgeons if medicolegal issues are addressed.
