The US Food and Drug Administration (FDA) have approved a mobile radiology application. This application allows physicians to view medical images on Apple’s iPhone and iPad devices. The application, Mobile MIM, allows physicians to view scans from CT, MRI, and nuclear medicine technology, such as positron emission tomography (PET). The application is not designed to replace full workstations and is indicated for use only when there is no access to a workstation. Radiology images taken in the hospital are sent to the portable wireless device through Mobile MIM. Doctors can measure distance on the image and image intensity values, as well as display measurement lines, annotations and regions of interest. The Mobile MIM application features sufficient labelling and safety features to overcome the risk of poor image display due to improper screen luminance or lighting conditions. The FDA used various portable devices to evaluate luminance, image quality, and noise in accordance with international standards and guidelines in its review.
