RC 805 - Daily use of mobile devices in radiology
Imaging Informatics Professional Issues Radiographers
Thursday, March 1, 16:00 - 17:30
Room: M 2
Moderator: O. Ratib (Geneva/CH)

Chairperson's introduction
O. Ratib; Geneva/CH
Learning Objectives

1. To give an overview of tools available on mobile devices for education and exam reporting.
2. To underline the impact of mobile devices in routine clinical activity.
3. To learn about the legislative backbone and potential drawbacks of mobile technology.


Mobile devices such as tablets and high-resolution smartphones are becoming widely available providing convenient mobile solutions for physicians and healthcare providers to access imaging data. This is particularly attractive in medicine where “nomad” physicians who need to be able access relevant patient data and images anywhere-anytime in their daily practice where they are rarely a single location. While they may not always be adequate for routine diagnostic tasks they provide a convenient mobile solution for on-call and remote consultations. There are different types of software architecture that can be implemented for such tasks. Two major different design are: (1) online web-based applications where the device serves as a “thin-client” to display images rendered and manipulated on a remote computer and (2) local applications that reside on the mobile device and can run independently after images have been downloaded on the device. The first solution requires the user to be constantly connected to the network, while the second solution can continue to function after disconnecting from the network. Most vendors are starting to provide web access to their imaging solutions that can be accessed from mobile devices. Web access can however be slow and dependent on reliable access to wireless network.

A. What did mobile devices change in radiology education?
E. Kotter; Freiburg/DE
Learning Objectives

1. To give an overview of tools available for e-learning.
2. To explore the potential impact of e-learning in the daily radiological practice.
3. To explore future developments and limits of e-learning.


E-learning has been used in radiology for more than 30 years. The lecture will give an introduction to and an overview of e-learning systems for radiology with emphasis on e-learning on mobile devices. Advantages and limitations of mobile e-learning will be discussed. An outlook to future development of e-learning will be given.

B. Is it appropriate to read a study on a smartphone or a tablet?

Learning Objectives

1. To give an overview of available DICOM viewers and software for reporting imaging studies.
2. To discuss technical requirements of mobile devices for use in imaging interpretation.
3. To provide insight on future developments of imaging viewing technology.


The portability of tablets and smartphones make them suitable for accessing and displaying digital radiological imaging studies particularly in on call or remote settings, in wards or clinics and in the emergency setting. The purpose of this display can be for primary diagnosis or for review. The portable device must be fit for purpose. The small screen size and limited display resolution of smartphones limits their appropriateness for primary diagnosis. However studies have shown equivalent diagnostic accuracy of tablets compared with DICOM-calibrated PACS workstation displays. It is now technically possible to satisfy the requirements for viewing large multi-image studies on mobile devices: processor and network speeds are fast enough to receive images quickly from a PACS; screen resolutions and DICOM conformance can display images with appropriate fidelity; memory and graphics processor capacities can allow image viewing and manipulation similar to that on a PACS workstation; and hospital information technology departments can institute appropriate management to ensure functional stability of mobile devices and security of the patient data displayed on them. Simultaneous comparative viewing of multiple studies is inevitably suboptimal on portable devices due to their limited screen real estate. Radiologists should consider exploiting mobile devices to raise their profile as clinical doctors, for example, using them to interact in person with their clinical colleagues on ward rounds and in out-patient departments, and with patients to explain their imaging to them.

C. Security and ethical issues of mobile device technology
E. R. Ranschaert; Mol/BE
Learning Objectives

1. To provide an overview of technical solutions for patients' image and data mobility.
2. To provide a risk assessment analysis (data loss, privacy, etc.) of mobile technology.
3. To give an overview of European legislation in relation to patient image and data mobility.


Medical specialists and radiologists are using mobile devices to share and exchange medical information and images with other health care professionals. Usually they need the advice regarding a diagnosis or treatment, sometimes in an acute setting. Popular messaging services such as whatsapp are often used for such purpose. Transmission of patient data with mobile devices and messaging services, however, does have several ethical and legal limitations, mostly related to the security and privacy of patients. Some questions need to be answered: is this type of communication unsafe and/or illegal, and if yes, why? Are there any regulations and/or guidelines available? Are there any secure solutions available? In this refresher course these issues will be discussed in more detail.

Panel discussion: Can mobile technology supplement stationary technology in radiology?

Discussion will address main controversies of the use of mobile technology in a clinical environment such as image quality, data mobility, safety and legal issues, etc.
