In this episode of the CurveBeam podcast, host Vinti Singh sat down with Dr. Martinus Richter, MD, Ph.D.to discuss the results of his latest published study: “Results of more than 11,000 scans with weight-bearing CT – Impact on costs, radiation exposure and procedure time.” This first-of-its-kind study examined the economic implications of CT scans versus radiographs for patients.

Dr. Richter is department head of the foot and ankle orthopedic surgery section at Hospital Rummelsberg in Rummelsberg, Germany and has published numerous studies in orthopedic journals.
Dr. Richter oversaw a study, which was conducted over more than five years. to assess the benefits of using weight bearing CT (WBCT) instead of a combination of weight bearing radiographs (R) and conventional CT (CT). The study looked at the modalities’ impacts on costs, radiation exposure and procedure time.
In the study, 11,009 scans, taken from July 2013 through March of 2019, were obtained from 4987 patients—45% (4,897) before treatment; 55% (6,022) at follow-up—with a yearly average of 1,957 WBCTs (bilateral scans). These were compared to 1,850 Rs (bilateral feet, dorsoplantar and lateral, metatarsal head skyline view) and 254 CTs obtained from 885 patients (RCT group) in 2012.
The conclusions help to solidify that not only can WBCT more precisely measure bone position than conventional R and CT scans, but also decreases the time needed for image acquisition by 77% and radiation dosage by 10%, while increasing institution financial profitability by $57.19 (51€) per patient.
For a premier orthopedic surgeon, you might be surprised to learn Dr. Cesar de Cesar Netto, has never broken a bone. Even as an athlete playing soccer, the founding member of the Weight Bearing CT Society never sustained an injury like the ones he sees from his patients in his orthopedic work. “I was a goalkeeper,” he says chuckling.
On today’s episode of Curvebeam Connect, host Vinti Singh, Curvebeam Marketing Manager, sits down with Dr. Cesar de Cesar Netto, M.D., Ph.D. of the University of Iowa Carver School of Medicine to learn more about the Brazilian surgeon and researcher and discuss advancements in extremity CT scans.
Since the WBCT Society held its first meeting in Berlin in 2016, the organization has presented at several conferences and made significant strides towards its mission, Dr. de Netto says.
Specifically, a recent imaging study of patients with adult-acquired flat foot, or flat foot deformity, found that 70 percent of those patients had some degree of subtalar joint subluxation and sinus tarsi impingement. Dr. de Netto was a co-author of the study that used weight bearing CT imaging and MRI, as opposed to two-dimension x-ray imaging.
“The foot is such a beautiful biomechanical machine with so many joints that I always thought X-Rays couldn’t really demonstrate to you what the deformity consisted of,” he says.

Weight-bearing CT scans have many benefits when compared to a weight-bearing X-ray. The problem is that the United Kingdom’s hospitals often don’t have the immediate capital to invest in the 3D technology.
On today’s episode of Curvebeam Connect, host Vinti Singh, Director of Marketing at CurveBeam talks to James Kraft, founder and CEO of The Standing CT Company, a provider of weight-bearing CT services to hospitals throughout the UK and Europe via mobile imaging vans.
“The question was how to get more of these into hospital in a way that was financially feasible,” Mr. Kraft said. “So, we came up with a mobile solution that could go from hospital to hospital.”
The mobile scanning unit has so far taken off with flying colors, and hospitals are beginning to adopt this structure. “Right now, we are doing a lot of one-off scanning days with our first unit. And the surgeons are very motivated to get it into their hospitals. They know the advantages,” Dr. Kraft said. “We plan to have our second mobile unit by end of the year and two to three more by 2020.”
The company is very focused on educating surgeons, radiologists, and clinicians about the units, the workflow of getting scans back to hospitals, and why mobile units are more cost-effective. To bring together all stakeholders, The Standing CT Company is hosting a full day conference in London on July 12.
“The event came from the idea of looking at what the industry needed to know, and our advisory board was very influential. The conference will have lots of sessions from experts about CT scanning, orthopedics, and more,” Mr. Kraft said.
Dr. Barg specializes in the care of the foot and ankle, as well as reconstruction of traumatic injuries to the foot, ankle replacement, and joint preserving procedures.
Prior to coming to the University of Utah, he was the head of the Orthopedic Department at the University of Basel in Switzerland.
Dr. Barg currently serves as a reviewer for numerous medical journals including Foot & Ankle International, Journal of Biomechanics, Clinical Anatomy, and BMC Musculoskeletal Disorders, and is well published in foot and ankle replacement.
Currently, Dr. Barg is working with a variety of other researchers on a series of weight-bearing CT projects, including two cadaver research studies. On working with Dr. Arne Burssens on a templating method, Dr. Barg said, “we’re able to compare the healthy side versus the injury side and can detect very small differences in imaging using weight-bearing, which we’re not able to do using conventional radiographs and MRI.”
Give this podcast a listen to hear Singh and Dr. Barg break down his recent presentation on evaluating syndesmosis, his discoveries on the effect that torque plays in syndesmosis measurement, and whether these findings could translate to imaging in the clinical setting.
CurveBeam is thrilled to announce the launch of its official podcast – CurveBeam Connect.
Each month, CurveBeam will bring its listeners voices from the clinic, the radiology reading room, medical conferences and more.
The featured guest for CurveBeam Connect’s inaugural episode is Dr. Francois Lintz, MD, a foot & ankle orthopedic surgeon at Clinique L’Union in Toulouse, France. He discusses why he believes weight bearing CT imaging should replace conventional radiography as the gold standard for diagnostic imaging of lower extremity conditions. He also discusses how he conceived the idea for TALAS, a semi-automatic tool for measuring hindfoot alignment in three dimensions.
