Top 5 Trends from RSNA 2018 in Chicago: PART TWO
As most of you in the industry know, the Radiological Association of North America (RNSA) held it's annual conference at the end of November... Countless vendors showed off their latest and greatest developments pertaining to medical imaging, and professionals and industry intellectuals informed us about what we can expect in the next few years.
We know that with so much information coming from the show, it's hard for important information to get lost in the shuffle. Well, the gracious folks at Aunt Minnie have compiled their Top 5 Trends again for us this year so that even if you didn't attend the conference, you now know some of the highlights. Read below for Trends #3, 4 and 5 in this second part of the 2-part series...
3. 3D Printing Approaches Key Milestone
Since RSNA launched its 3D Printing Special Interest Group in 2013, the amount of time and space dedicated to the field during the annual meeting has grown enormously each year. RSNA 2018 was no exception to this trend, with a generous number of posters, refresher courses, technical exhibits, and oral presentations aimed at increasing the awareness of 3D printing.
The technology's pervasiveness this year -- especially in scientific sessions -- made clear that medical 3D printing long ago transitioned from being merely a flashy idea into an effective application grounded in clinical work. This year's conference included discussions ranging from the logistics of starting a hospital 3D printing lab and creating cost-effective 3D-printed anatomical models to the various ways in which clinicians have been using such models to boost treatment efficiency.
Research presentations at RSNA 2018 demonstrated the potential benefits of 3D-printed models in improving presurgical planning and intraoperative guidance, as well as patient education. In previous years, these presentations were primarily case studies involving a dozen or so 3D-printed models. At RSNA 2018, however, several groups showed the technology to be useful on an even grander scale, to the tune of hundreds of distinct patient-specific models created for the evaluation of a particular organ or disease.
Furthermore, growth in medical 3D printing seems primed to continue full steam ahead in light of the American Medical Association's acceptance of a category III current procedural terminology (CPT) proposal for 3D anatomic modeling; the proposal was led by the American College of Radiology.
The four new CPT codes, slated to be effective starting July 2019, will finally allow radiologists and other clinicians to seek reimbursement from the U.S. Centers for Medicare and Medicaid Services (CMS) for 3D printing services -- possibly surmounting one of the chief barriers to the integration of 3D printing in healthcare. Researchers from multiple U.S. institutions underscored the magnitude of this event in a Sunday refresher course on 3D printing at RSNA 2018.
"Before now, all 3D printing was volunteer work, but now there's a way to actually get reimbursement from CMS for patients who need 3D printing," Dr. Frank Rybicki, PhD, chair of radiology at the Ottawa Hospital, told AuntMinnie.com. "The fact that the codes exist and they cleared is huge. It's a really big deal in radiology."
The coding decision will also apply to other advanced 3D imaging techniques, which are increasingly becoming intertwined with 3D printing. In one such example at RSNA 2018, investigators from New York created both augmented reality and 3D-printed kidney and prostate models using the same MRI and CT scans. The shared processing steps required for 3D printing and other forms of 3D modeling -- most notably virtual and augmented reality -- may ease the partial unification of their workflows.
As 3D printing research expands and the technology ramps up its integration into hospitals around the world, radiologists appear positioned to cement their place as leading figures in the discipline. Medical 3D printing, like artificial intelligence, has the earmarks of a medium through which radiologists may be able to situate themselves at the "epicenter of care," as Rao urged the community to do in her opening address.
What's more, the early application of 3D printing in medicine has highlighted its collaborative nature: Every scientific presentation depended upon a joint effort among scientists, engineers, and clinicians from a variety of specialties, including radiology. Collaboration to this degree may ultimately improve the quality of research and, perhaps most importantly, of patient care.
