Transforming Bunion Assessment with Weight Bearing CT
By Dr. David Soomekh, DPM Foot and ankle specialist and surgeon, sports medicine & reconstructive foot and ankle surgery, Foot & Ankle Specialty Group, Beverly Hills, CA
Cone Beam Weight Bearing Computed Tomography of Ankle Arthritis and Total Ankle Arthroplasty
Key Points: Cone Beam CT (CBCT), specifically WBCT three-dimensional (3D) visualization approach allows for a more accurate assessment of foot alignment with attention to planus, cavus, varus or valgus deformities. Post-operatively, weight bearing CT (WBCT) has the potential to better…
Extremity CT Imaging for Orthopedics
The HiRise is a low dose cone beam CT system. The upper extremity scans are quick and allow for patients to be scanned in a comfortable seated position.
Estimation of Radiographic Joint Space of the Trapeziometacarpal Joint with Computed Tomographic Validation
Key Points: Cone Beam Computed Tomography (CBCT), a three-dimensional (3D) imaging modality, can readily evaluate complex joint structures. The most important radiographic (X-Ray) criterion used in surgical decision making for osteoarthritis is joint space narrowing (JSN), or the loss of…
Advantages of Cone Beam Computed Tomography for Evaluation of Subchondral Insufficiency Fractures of the Knee Compared to MRI
Key Points: Cone Beam CT (CBCT) is superior in assessing bony structures compared to magnetic resonance imaging (MRI) In this study, there was a 40% rate of discrepancy when grading knee subchondral insufficiency fractures on CBCT vs. MRI, with MRI…
Automation Improves the Efficiency of Weight Bearing CT Scan 3D Volumetric Assessments of the Syndesmosis
Key Points: WBCT 3D Measurements volumetric measurements of the syndesmosis have shown to have a high specificity (83.3%) and sensitivity (95.8%) for the diagnosis of subtle injuries. Manual 3D WBCT volume measurement of syndesmosis, a promising method to detect instability,…
