  • PURPOSE: The present study aimed to compare the reliability of interpreting CT scans viewed by orthopedic surgeons in two ways for diagnosing, classifying, and treatment planning for thoracolumbar spine fractures: (1) captured as video clips from standard workstation-based picture archiving and communication system (PACS) and sent via a smartphone-based instant messaging application for viewing on a smartphone; and (2) viewed directly on a PACS.


    METHODS: CT scans were captured by use of an iPhone 6 smartphone from a computer screen displaying PACS. Then by use of the WhatsApp instant messaging application, video clips of the scans were sent to the personal smartphones of five spine surgeons. These evaluators were asked to diagnose, classify, and determine the course of treatment for each case. Evaluation of the cases was repeated 4 weeks later, this time using the standard method of workstation-based PACS. Intraobserver agreement was interpreted based on the value of Cohen's kappa statistic.
  • CONCLUSIONS: Video clips of CT scans can be readily captured by a smartphone from a workstation-based PACS and then transmitted by use of the WhatsApp instant messaging application. Diagnosing, classifying, and proposing treatment of fractures of the thoracic and lumbar spine can be made with equal reliability by evaluating video clips of CT scans transmitted to a smartphone or by the standard method of viewing the CT scan on a workstation-based PACS. Evaluating video clips of CT scans transmitted to a smartphone is a readily accessible, simple, and inexpensive method. We believe that it can be reliably used for consultations between the emergency physicians or orthopedic or neurosurgical residents with offsite, on-call specialists. It might also enable rural orcommunity emergency department physicians to communicate more efficiently and effectively with surgeons in tertiary referral centers.

  • “Our results showed similarly high levels of agreement for CAD scores between our test readers and reference readers, independent of whether an iPhone or standard workstation was used. Intraobserver intertechnology agreement was higher for each test reader than their corresponding interobserver agreement with the reference reader.”

  • “Coronary CTA examinations can be interpreted on a smartphone with diagnostic accuracy comparable to a standard workstation. DICOM-viewing app on the iPhone may facilitate urgent coronary CTA review when a workstation is not available.”

  • “ Server side rendering and processing allows manipulation of images to be done where the information is stored. The image currently being viewed on the devise is the only one that is stored at that point in time. Because there is minimal information on the devise at any given time, the method of viewing radiology images is the most secure.”

  • “ With the given study sample, the diagnostic performance of the offsite smartphone readings did not differ significantly from that of the in-house preliminary reports. However, the smartphone readings provided higher diagnostic confidence than the preliminary reports.”

  • “ Our results suggest that a mobile consultation is potentially a useful adjunct to an on-call radiologist’s preliminary report when the on-call radiologist’s diagnosis of appendicitis is not conclusive.”
