Effects of nonstationary system blur on radiomic texture features of trabecular bone in normal and ultra‐high resolution CT Open
Background CT image texture features (TFs) of trabecular bone are being investigated as predictive markers in osteoporosis (OP) and osteoarthritis (OA). To support the development of such radiomic approaches, the reproducibility of bone TF…
EP5.26 Acetabular Version Following Periacetabular Osteotomy: Does Actual, Computed Tomography Correction Differ from Perceived, Radiographic Correction? Open
Introduction: Anterior and posterior wall indices (AWI and PWI, respectively) have been traditionally utilized in the radiographic evaluation of acetabular wall contributions to femoral head coverage. This study aimed to determine if the r…

Baseline‐to‐loaded changes in regional tibial cartilage thickness, T1ρ and T2: Utilization of an MRI compatible loading device Open
The objective of the study was to evaluate tibial cartilage thickness (TCT), T1ρ and T2 values within both loaded and baseline configurations in a cadaveric knee model using a 3D bone based tibial coordinate system. Ten intact cadaveric kn…
Fully automated determination of robotic pedicle screw accuracy and precision utilizing computer vision algorithms Open
Historically, pedicle screw accuracy measurements have relied on CT and expert visual assessment of the position of pedicle screws relative to preoperative plans. Proper pedicle screw placement is necessary to avoid complications, cost and…

Morphology of the scaphotrapeziotrapezoid joint: A multi‐domain statistical shape modeling approach Open
The scaphotrapeziotrapezoid (STT) joint is involved in load transmission between the wrist and thumb. A quantitative description of baseline STT joint morphometrics is needed to capture the variation of normal anatomy as well as to guide s…

Detection of scapholunate interosseous ligament injury using dynamic computed tomography-derived arthrokinematics: A prospective clinical trial Open
Scapholunate interosseous ligament injuries are a major cause of wrist instability and can be difficult to diagnose radiographically. To improve early diagnosis of scapholunate ligament injuries, we compared injury detection between bilate…
OrthoFusion: A Super-Resolution Algorithm to Fuse Orthogonal CT Volumes Open
OrthoFusion, an intuitive super-resolution algorithm, is presented in this study to enhance the spatial resolution of clinical CT volumes. The efficacy of OrthoFusion is evaluated, relative to high-resolution CT volumes (ground truth), by …
Utility of Zero Echo Time MRI for the Diagnosis and Characterization of Ankle Fractures Open
Background: Zero echo time (ZTE) imaging is a relatively new magnetic resonance (MR) pulse sequence that provides bone-soft tissue contrast similar to that of computed tomography (CT). Purpose: We sought to (1) determine the accuracy of ZT…
Assessment of Patellar Vascularity after Patellar Cartilage Restoration via Lateral Parapatellar Approach: Analysis Using Dynamic Contrast-Enhanced Magnetic Resonance Imaging Open
Objective Patellofemoral cartilage restoration procedures, including osteochondral allograft, particulated juvenile cartilage, and matrix-induced autologous chondrocyte implantation, have been shown to be effective treatments for patellofe…

Evaluation of Scapholunate Injury and Repair with Dynamic (4D) CT: A Preliminary Report of Two Cases Open
Background In predynamic or dynamic scapholunate (SL) instability, standard diagnostic imaging may not identify SL interosseous ligament (SLIL) injury, leading to delayed detection and intervention. This study describes the use of four-dim…

MRI-based Texture Analysis of Trabecular Bone for Opportunistic Screening of Skeletal Fragility Open
Context Many individuals at high risk for osteoporosis and fragility fracture are never screened by traditional methods. Opportunistic use of imaging obtained for other clinical purposes is required to foster identification of these patien…

Differences in the magnetic resonance imaging parameter T2* may be identified during the course of canine patellar tendon healing: a pilot study Open
These findings display tendon healing in response to an imposed strain and present the utility of qMRI to evaluate longitudinal differences of patellar tendon T2* values in a model of induced subclinical tendon damage. The qMRI technique o…
