The Stepping Stone to Structured Reporting: What Does Natural Language Processing Mean for Radiology

Features | Monday, April 19 2010
Written by Jeff Byers
Like much of healthcare, radiology is a state of flux. From reimbursement cuts to adopting EMRs, day-to-day operations are being transformed. Dictation software is evolving in the radiology field as natural language processing (NLP) is being developed to harness content from dictated, free text into a manageable report that can be used in radiology.

Feature: U.S. needs national strategy to curb imaging overutilization

Medical imaging overutilization--a growing concern in the U.S.--exposes patients to unnecessary radiation, while also adding to rising healthcare costs, according to a study published online Aug. 24 in Radiology. In an interview, William R. Hendee, PhD, lead author, reviewed various methods by which medical imaging could be curtailed.

CMS Webinar: Incentive payments to offset EHR adoption, not reimburse
