Case Study: Standing CT for Improved Visualization of Knee Cartilage & Menisci

ct mri

MRI is the current standard of care for non-invasive visualization of cartilage and menisci, but without utilizing weight bearing methods, a full and accurate evaluation isn’t likely. A recent case study reveals important advantages of weight bearing CT over the standard MRI.

With standing CT, 3D imaging can be obtained under physiological load, offering a more complete assessment picture.Standing CT also provides a clearer view of meniscal position and potential pathology. In addition, cartilage thickness is easily measured, and cartilage delineation is improved.

A weight-bearing image can reveal a variety of knee flexion angles not possible in an MRI knee coil.

Assessment accuracy is a clear advantage, but there is an important financial aspect to consider, with the CT scan costing roughly 40% less than an MRI.

CurveBeam offers the innovative weight bearing CT technology required to give the best care to orthopedic patients. Complete the form below to download the case study in its entirety.

CurveBeam Teams Up with the Paley Foundation to Change the Lives of Children

paley ride 1On June 3, the Paley Foundation hosted the Bill Bones Saving Limbs Ride to benefit the Tommy Fund, a charity for children with limb defects. The annual event features a 15 and 55-mile early morning bike ride in West Palm Beach, riding to and from Boca Raton. In addition, there is a family fun ride for bikes, scooters, or wheelchairs. CurveBeam is proud to be a sponsor of this year’s event.

The Foundation

The unLIMBited Foundation is a team of passionate individuals who offer children a chance to fulfill their dreams through limb-saving medical and surgical treatments at the world-renowned Paley Institute in West Palm Beach, Florida. When children are born with severe congenital limb defects, they are often offered amputation as a sole solution. Dr. Dror Paley and The Paley Institute, along with the unLIMBited team, advocate for an alternative solution: limb saving and corrective surgery. The Tommy Fund has been established by the joined forces of the Paley Foundation and the unLIMBited Foundation to provide much needed financial assistance to those families undergoing the extensive surgery and rehabilitation. Patient families relocate to Florida for up to six months to receive these treatments. The Tommy Fund helps those families cover the costs of this extensive and life-altering endeavor._1 - paley fund ride

Tommy’s Story

Tommy Morissey is an ordinary seven-year-old boy, who happens to also play golf like a pro. And he does so with only one arm. Tommy, who is the namesake of the fund, was born without much of his right arm. By age three, amazingly, he was a golf prodigy, and now at age seven, he travels the globe speaking on behalf of children like himself in an effort to increase awareness, reduce stereotypes, and raise money to help this cause.

Sponsorship by CurveBeam

The proceeds gained by the Bill Bones Saving Limbs Ride go directly to the Tommy Fund to assist families in need of medical services and living expenses during a child’s treatment. The team at CurveBeam cannot think of a better way to invest our resources than by sponsoring this incredible event. As a pioneer in the medical imaging industry, CurveBeam is deeply concerned with the health and welfare of those dealing with orthopedic and podiatric challenges. As manufacturers of Cone Beam CT imaging equipment, we believe it is essential to give back to the communities represented by the imaging patients we ultimately serve; our littlest patients hold a special place in our hearts as we aim to improve our imaging solutions continually.

Biomedical Engineer Presents Important Findings on the Responsiveness of Standing CT for Measurement of Knee Joint Space Narrowing at IOWAI 2018

image1

Imaging is a critical tool in the diagnosis and management of osteoarthritis. The International Workshop on Osteoarthritis Imaging (IOWAI) was created to offer opportunities for osteoarthritis investigators to discuss issues and share findings related to imaging. This Workshop was first held in Ainring, Germany in 2017 and is now held annually at various locations in Europe and North America. This year’s IOWAI will be held in Menton, France, on July 5-8. Thought leaders and influencers from academia, regulatory and funding agencies, and the medical equipment industry will be in attendance.

Kaitlin Rabe, Biomedical Research Assistant at the University of Kansas Medical Center, will be presenting a poster titled, “Responsiveness of Standing CT for Measurement of Knee Joint Space Narrowing Over 60 Months.” The study was sponsored by the National Institutes of Health, the University of Iowa, and the University of California, San Francisco.image2

In the workshop, Ms. Rabe will discuss the limitations of two-dimensional radiography when measuring joint space width (JSW). These 2D weight-bearing radiographs traditionally suffer from poor sensitivity when used to detect knee osteoarthritis and produce poor correlation with symptom progression.

Much of these issues can be attributed to the inherent limitations in the 2D radiography procedure, such as the dependence on X-ray beam alignment with the medial tibial plateau. In addition, the temporal and spatial heterogeneity of structural progression of knee OA limits the responsiveness of radiographic JSW to diagnose disease progression. MRI offers important advantages over 2D radiography, but is typically non-weight-bearing.

Standing CT (SCT) imaging holds the potential to overcome these limitations and enhance responsiveness in three-dimensional JSW measurements. This is because JSW is measured in a loaded position while avoiding bony overlap and error due to beam angle variations.

In her workshop, Ms. Rabe will provide preliminary data for the responsiveness of 3D JSW on SCT over 60 months using an early prototype of the CurveBeam LineUP system. The LineUP is a compact, ultra-low dose Cone Beam CT imaging system specifically designed for the orthopedic and podiatric specialties. Preliminary data calculated for 33 knees from 19 participants over 60 months support the hypothesis that 3D JSW exhibits a greater responsiveness than has been reported for radiography, similar to that for quantitative cartilage thickness measured on MRI over 12-months.

To get all the details on this important study, be sure to attend Ms. Rabe’s workshop at the IOWAI in Menton, France, July 5-8. For more details on accommodations and the all the workshops at this important conference, go to https://www.iwoai.org/.

WBCT ISG Special Session takes place next week in Boston

nettoGuest post by Dr. Cesar de Cesar Netto, MD, PhD

Dr. Netto is currently a foot and ankle fellow at Hospital for Special Surgery (HSS). He is part of the WBCT ISG board. His main research interests are weight bearing CT imaging and adult acquired flatfoot deformity. 

Weight-Bearing Cone Beam CT (WB CBCT) is a reality. This relatively new imaging technology has quickly transformed the ability of orthopedic surgeons to assess simple and complex deformities of the foot and ankle.  It is following the path to soon become the standard imaging study for foot and ankle pathologies.

The Weight-Bearing CT International Study Group (WBCT ISG) was formally founded in 2017. Our mission is to promote dialogue and collaboration on WB CBCT research initiatives, and to develop standardized protocols for WB CBCT measurements and imaging analysis and is jointly sponsored by Carestream, CurveBeam and Planmed.

The Group is comprised of active and passive members from relevant international surgical and radiology foot and ankle societies, and research projects are conducted and published in collaboration.  The main tasks of the WBCT ISG are:

  • To promote and improve research using three-dimensional imaging with WB CBCT
  • To standardize the methodology regarding measurement methods on WB CBCT images
  • To serve as a platform of communication for foot and ankle surgeons, radiologists and other healthcare providers with scientific interest in this field
  • To offer guidelines and reviews regarding the indications and use of WB CBCT at an international level

The WBCT ISG has been promoting Scientific Sessions at least once or twice a year, usually during the most important orthopedic foot and ankle societies meetings in the US and Europe. The sessions have been a great opportunity for people to get to know the technology and learn from the experience of the most important authors that have been publishing on the field. Our next WBCT ISG Scientific Session will take place in Boston (Massachusetts, US) during the American Orthopedic Foot and Ankle Society (AOFAS) Annual Meeting. We are meeting on July 12th, 2018, from 5:00 p.m. to 6:30 p.m., at the Hynes Convention Center, Room 310.
