These authors explored the diagnostic yield of DSA in patients with SAH and previously negative CTA or MRA. A total of 55 patients who presented with diffuse SAH, perimesencephalic SAH, or sulcal SAH received CTA (n= 47) or MRA (n= 8). Despite normal findings on CTA or MRA, DSA showed vascular lesions in 11% of patients with diffuse SAH and in 1 patient with sulcal SAH. The investigators concluded that DSA is a valuable tool in patients with diffuse or sulcal SAH in whom previous noninvasive examinations are negative.

Here, the number of unnecessary CT cervical studies despite proper application of NEXUS criteria was assessed. The authors also tried to determine indications for ordering studies in the absence of guideline criteria. Of 507 CT studies, only 5 (1%) were positive while 81 of the 502 patients with negative findings (16%) were imaged despite meeting all NEXUS criteria for non-imaging. The most common indications for the studies were a dangerous mechanism of injury and subjective neck pain. Strict application of NEXUS criteria may result in considerable reduction of screening CT studies of the cervical spine.
