We examined the potential of the iPad 2 as a teleradiologic tool for evaluating brain computed tomography (CT) with subtle hemorrhage in the conventional lighting conditions which are common situations in the remote CT reading. The comparison of the clinician's performance was undertaken through detecting hemorrhage by the iPad 2 and the clinical liquid crystal display (LCD) monitor. We selected 100 brain CT exams performed for head trauma or headache. Fifty had subtle radiological signs of intracranial hemorrhage (ICH), while the other 50 showed no significant abnormality. Five emergency medicine physicians reviewed these brain CT scans using the iPad 2 and the LCD monitor, scoring the probability of ICH on each exam on a five-point scale. Result showed high sensitivities and specificities in both devices. We generated receiver operating characteristic curves and calculated the average area under the curve of the iPad 2 and the LCD (0.935 and 0.900). Using the iPad 2 and reliable internet connectivity, clinicians can provide remote evaluation of brain CT with subtle hemorrhage under suboptimal viewing condition. Considering the distinct advantages of the iPad 2, the popular out-of-hospital use of mobile CT teleradiology would be anticipated soon.

“…A portable high-resolution display screen, running image viewing software, would be a key requirement to allow off-site radiologists to provide second line support to on-call trainee residents interpreting inhospital emergency studies, allowing safe and timely communication of important radiological findings to the clinician that may affect the patient's treatment while at the same time removing restrictions in physical location. In recent years, mobile computing devices such as laptop personal computers, personal digital assistants (PDA) and smartphones have been introduced into the broader consumer electronics market, and their wireless mobility has been explored for use in medical teleconsultation [1][2][3][4][5][6][7][8][9][10][11]. However, although laptop computers have large screens and computing power, they are hampered by excess weight and short battery life.…”

The iPad Tablet Computer for Mobile On-Call Radiology Diagnosis? Auditing Discrepancy in CT and MRI Reporting

et al. 2012

Tablet computers such as the iPad, which have a large format, improved graphic display resolution and a touch screen interface, may have an advantage compared to existing mobile devices such as smartphones and laptops for viewing radiological images. We assessed their potential for emergency radiology teleconsultation by reviewing multi-image CT and MRI studies on iPad tablet computers compared to Picture Archival and Communication Systems (PACS) workstations. Annonymised DICOM images of 79 CT and nine MRI studies comprising a range of common on-call conditions, reported on full-featured diagnostic PACS workstation by one Reporting Radiologist, were transferred from PACS to three iPad tablet computers running OsiriX HD v 2.02 DICOM software and viewed independently by three reviewing radiologists. Structured documentation was made of major findings (primary diagnosis or other clinically important findings), minor findings (incidental findings), and user feedback. Two hundred and sixty four readings (88 studies read by three reviewing radiologists) were compared, with 3.4 % (nine of 264) major discrepancies and 5.6 % (15 of 264) minor discrepancies. All reviewing radiologists reported favorable user experience but noted issues with software stability and limitations of image manipulation tools. Our results suggest that emergency conditions commonly encountered on CT and MRI can be diagnosed using tablet computers with good agreement with dedicated PACS workstations. Shortcomings in software and application design should be addressed if the potential of tablet computers for mobile teleradiology is to be fully realized.

Abstract. Multi-disciplinary team meetings (MDTMs) are essential in healthcare, where medical specialists discuss diagnosis and treatment of patients. We introduce a prototype multi-display groupware system, intended to augment the discussions of medical imagery, through a range of input mechanisms, multiuser interfaces and interaction techniques on multi-touch devices and pen-based technologies. Observations of MDTMs, as well as interviews and observations of surgeons and radiologists, serve as a foundation for guidelines and a set of implemented techniques. We present a detailed analysis of a study where the techniques' potential was explored with radiologists and surgeons of different specialties and varying expertise. The results show that the implemented technologies have the potential to bring numerous benefits to the team meetings with minimal modification to the current workflow. We discuss how they can augment the expressiveness and communication between meeting participants, facilitate understanding for novices, and improve remote collaboration.
