      Screening Cervical Spine CT in the Emergency Department, Phase 2: A Prospective Assessment of Use

      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.

      Neuroradiology Critical Findings Lists: Survey of Neuroradiology Training Programs

      These authors questioned neuroradiology fellowship programs about the availability of “critical findings” lists and, if available, how these are distributed to trainees and whether they were vetted by corresponding clinical departments. Over one-half of programs responded and 41% had such lists. The lists were distributed during orientation, sent or made available electronically, and posted in work areas. Less than 25% of lists were developed with input from other departments. The most common entities found in the lists were: brain hemorrhage, acute stroke, cord compression, brain herniation, and spine fracture.
