Background and Purpose: The display resolution of the Apple iPad? is 1024 × 768 pixels, which greater than that required for generating typical CT or MRI images. purpose this study to determine if specific MR sequences can be interpreted accurately on mobile device/PACS software platforms when compared a traditional stationary high monitor/PACS radiological workstation. If so, allows radiologists provide comparable interpretation as they were onsite at an imaging center hospital. Materials Methods: This investigator initiated, single site, retrospective, nonrandomized, IRB approved study. Five included in Each independently high-resolution LCD monitors via eFilm? well device using Osirix? program. Repeat interpretations performed, with 4 weeks minimum interval between each patient. investigation included: 50 patients CTA perfusion imaging, brain, spine, image orders generated through emergency room requests. Subsequently, interpretive results radiologist patient statistically evaluate intra-observer inter-observer reliability. Results: parameters set within brain studies demonstrated excellent variability. All variability Cohen's kappa value > 0.75. values board certified neuroradiologist all parameters; resident had good variability, majority near Conclusions: data statistical analysis portable devices such adequate diagnose acute central nervous system injuries other non-acute pathology.
