“…Many direct-screen photographing methods using PDAs with either an external or a built-in digital camera that enables direct digital capturing of the PC screen have been researched. 5,6 They can achieve timely transmission with easy operation, but the image distortion occurring during the capturing process compromises the high-quality display necessary for radiological images.…”

“…An alternative to this method is to photograph the PACS monitor using a digital camera, which allows the user to bypass the menu navigation system. 5,6 Because most PDA phones have a built-in digital camera, the use of a PDA phone can be convenient to perform both the photographing and transmitting processes and can also avoid a synchronization problem. However, some distortions occurring during the photographing process cannot be avoided.…”

Remote teleconsultation by specialists is important for timely, correct, and specialized emergency surgical and medical decision making. In this paper, we designed a new personal digital assistant (PDA)Yphone-based emergency teleradiology system by combining cellular communication with Bluetooth-interfaced local wireless links. The mobility and portability resulting from the use of PDAs and wireless communication can provide a more effective means of emergency teleconsultation without requiring the user to be limited to a fixed location. Moreover, it enables synchronized radiological image sharing between the attending physician in the emergency room and the remote specialist on picture archiving and communication system terminals without distorted image acquisition. To enable rapid and finequality radiological image transmission over a cellular network in a secure manner, progressive compression and security mechanisms have been incorporated. The proposed system is tested over a code division Multiple Access 1Â-Evolution Data-Only network to evaluate the performance and to demonstrate the feasibility of this system in a real-world setting.

An instant image transfer system can be used to support rapid medical and imaging decision making in an emergency situations when doctors are away from the hospital [1][2][3] . There are several Web-based picture archiving and communication systems, which allows access to a patient's radiological images from outside the hospital 1 . However, they are felt to be not appropriate for use in time-critical emergency cases as mentioned in previous studies 4,5 . Handheld devices like smart-phones and personal digital assistants (PDAs) have become increasingly prevalent in modern society [6][7][8] and 46% of attending physicians and trainees 9 and 45% of radiologists are using handheld devices [8][9][10] . However, ABSTRACT:Objective: To assess the feasibility of iPhone-based teleradiology as a potential solution for the diagnosis of acute cervico-dorsal spine trauma. Materials and Methods: We have developed a solution that allows visualization of images on the iPhone. Our system allows rapid, remote, secure, visualization of medical images without storing patient data on the iPhone. This retrospective study is comprised of cervico-dorsal computed tomogram (CT) scan examination of 75 consecutive patients having clinically suspected cervico-dorsal spine fracture. Two radiologists reviewed CT scan images on the iPhone. Computed tomogram spine scans were analyzed for vertebral body fracture and posterior elements fractures, any associated subluxation-dislocation and cord lesion. The total time taken from the launch of viewing application on the iPhone until interpretation was recorded. The results were compared with that of a diagnostic workstation monitor. Inter-rater agreement was assessed. Results: The sensitivity and accuracy of detecting vertebral body fractures was 80% and 97% by both readers using the iPhone system with a perfect inter-rater agreement (kappa:1). The sensitivity and accuracy of detecting posterior elements fracture was 75% and 98% for Reader 1 and 50% and 97% for Reader 2 using the iPhone. There was good inter-rater agreement (kappa: 0.66) between both readers. No statistically significant difference was noted between time on the workstation and the iPhone system. Conclusion: iPhone-based teleradiology system is accurate in the diagnosis of acute cervicodorsal spinal trauma. It allows rapid, remote, secure, visualization of medical images without storing patient data on the iPhone.RÉSUMÉ: Téléradiologie basée sur le iPhone pour le diagnostic du traumatisme aigu de la colonne cervicale et dorsale.

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