Abstract Three-dimensional (3D) magnetic resonance imaging of the spine is now clinically feasible due to technological advancements. Its advantages over two-dimensional include higher in-plane spatial resolution and ability for reformation in any plane that enables time savings image acquisition aids more accurate interpretation. Multispectral 3D techniques around metal are sometimes useful evaluating anatomy adjacent spinal fixation hardware. gradient-recalled echo sequences, including...
This Institutional Review Board–approved pilot study attempted to detect the correlation between ultrasound shear wave elastographic measures and tendon loads. Five male fresh‐frozen cadaveric Achilles tendons were loaded in 10‐N increments from 0 60 N. Shear velocity measurements within each obtained at load longitudinal transverse orientations. correlated with tension on both plane imaging showed moderate strong positive coefficients, respectively. Of note, limitations of clinically...
We report our experience with 6 patients who had total knee replacements lateral-sided pain, referred for ultrasound (US) assessment and US-guided injection. All cases showed an osteophyte within the popliteus sulcus of lateral femoral condyle impinging on adjacent tendon. Five reported improvement symptoms immediately after injection anesthetic a steroid. Ultrasound has unique role in imaging because its real-time capabilities absence artifacts at tendon origin.
Zero echo time (ZTE) imaging is a relatively new magnetic resonance (MR) pulse sequence that provides bone-soft tissue contrast similar to of computed tomography (CT).
Polyethylene post fracture is a recognized complication of posterior stabilized total knee arthroplasty. Two radiologists retrospectively reviewed MRI examinations 19 reported fractures in 18 patients; all were subsequently confirmed surgically with no false-positive cases. All visualized as combination deformity and signal-void fragment joint recess. A metal artifact reduction 3D multispectral imaging sequence improved visualization versus conventional sequences 47%
Clinical diagnosis of partial flexor tendon lacerations is challenging because function may be preserved. Although some tears can managed conservatively, pain, stiffness, and triggering/locking result, requiring surgical management. The mechanism by which this occurs has been investigated in animal cadaver studies but not demonstrated patients with real-time, vivo imaging. Here, we present a case tear presenting severe pain locking that was diagnosed before surgery characterized dynamic ultrasound.
Isotropic 3D MRI, with the addition of deep-learning based reconstruction algorithms (DLRecon), facilitates faster acquisition times and multiplanar reformatting. We compared interobserver agreement for cervical spine neural foraminal (NF) stenosis assessment T2-weighted fast spin echo (T2w-FSE) MR images DLRecon to those standard-of-care (SOC) 2D T2w-FSE images. demonstrated that inter-observer was high both sequences in NF stenosis, but more consistent between readers at each level...
