Article Abstract
Objective: To evaluate the feasibility and repeatability of in vivo measurement of stiffness gradients by means of acoustoelastography in the superficial digital flexor tendons (SDFTs) of clinically normal horses.
Animals: 15 clinically normal horses.
Procedures: For each horse, stiffness gradient index and dispersion values for SDFTs in both forelimbs were evaluated in longitudinal orientation by use of acoustoelastography at 3 sites (5, 10, and 15 cm distal to the accessory carpal bone) by 2 observers; for each observer, data were acquired twice per site. The left forelimb was always scanned before the right forelimb. Lifting of the contralateral forelimb with the carpus flexed during image acquisition resulted in the required SDFT deformation in the evaluated limb. Interobserver repeatability, intraobserver repeatability, and right-to-left limb symmetry for stiffness gradient index and dispersion values were evaluated.
Results: Stiffness gradient index and dispersion values for SDFTs at different locations as well as effects of age or sex did not differ significantly among the 15 horses. Interclass correlation coefficients for interobserver repeatability, intraobserver repeatability, and limb symmetry revealed good to excellent agreement (intraclass correlation coefficients, > 0.74).
Conclusions And Clinical Relevance: Results indicated that acoustoelastography is a feasible and repeatable technique for measuring stiffness gradients in SDFTs in clinically normal horses, and could potentially be used to compare healthy and diseased tendon states.

Diffusion-weighted imaging (DWI) has been frequently used to examine age-related deterioration of white matter microstructure and its relationship to cognitive decline. However, typical tensor-based analytical approaches are often difficult to interpret due to the challenge of decomposing and (mis)interpreting the impact of crossing fibers within a voxel. We hypothesized that a novel analytical approach capable of resolving fiber-specific changes within each voxel (i.

Undifferentiated pleomorphic sarcoma, an exceedingly rare and aggressive primary cardiac tumor arising from mesenchymal stem cells, is associated with poor prognosis and high mortality despite adequate treatment. A 52-year-old female presented with a 2-month history of angina and dyspnea on exertion. Her clinical history included severe acute respiratory syndrome coronavirus 2 myocarditis and iron deficiency anemia.

Spinal cord sarcoidosis, an uncommon manifestation of neurosarcoidosis, presents diagnostic and therapeutic challenges because the condition is rare and has diverse clinical manifestations that can mimic other conditions such as multiple sclerosis and neuromyelitis optica spectrum disorder. A middle-aged African American female with a history of idiopathic intracranial hypertension and hydrocephalus with ventriculoperitoneal shunt presented with progressive, predominantly left-sided gait instability, weakness, and paresthesia. Cerebrospinal fluid showed lymphocytosis, red blood cells, elevated oligoclonal bands, and elevated kappa free light chains, concerning for multiple sclerosis.

Background: Even patients with normal computed tomography (CT) head imaging may experience persistent symptoms for months to years after mild traumatic brain injury (mTBI). There is currently no good way to predict recovery and triage patients who may benefit from early follow-up and targeted intervention. We aimed to assess if existing prognostic models can be improved by serum biomarkers or diffusion tensor imaging metrics (DTI) from MRI, and if serum biomarkers can identify patients for DTI.

A 79-year old Caucasian male with metastatic hormone refractory prostate cancer and bilateral nephrostomy was admitted to the emergency department due to 4-day bloody urethral discharge, weakness and dizziness. The patient was treated with the luteinizing hormone-releasing hormone-antagonist and abiraterone acetate plus prednisone, dabigatran 150 mg bid (for atrial fibrillation and coronary heart disease) and 5-aminosalicylic acid for the management of mild ulcerative colitis. Imaging revealed bladder overdistention and blood analysis low levels of hematocrit (HCT) and hemoglobin (HGB) (HCT, 22%; HGB, 7.
