15 top innovators in imaging informatics
Radiology is facing rapid change on many fronts—technology is more complex than ever, more IT tools are being developed to support radiologists and new economic forces are changing the financial dynamics for those working in this important branch of medicine. Despite the challenges, Health Data Management has identified several leaders in the field who are finding ways to exploit new technology to improve the effectiveness and efficiency of the radiology department.
Alkasab-Tarik-CROP.jpg
Tarik Alkasab, MD
Title: Assistant Professor of Radiology
Organization: Massachusetts General Hospital

Alkasab recently was a lead author of a study in the Journal of the American College of Radiology that advocated an open authorizing system for point of care decision support tools. He and his colleagues contend that decreasing unnecessary variation in radiology reporting is a key to success in value-based payment models and also is good for patient care. The goal is to represent radiology clinical guidelines as structured and machine-readable Extensible Markup Language documents. Also advocated is development of new tools that voice recognition vendors can use to extend the commercial tools currently in use.
