Sweep imaging with Fourier transform (SWIFT) method has been developed to image tissues with very short T values, such as cortical bone. The purpose of this study was to measure the T value of the rat cortical bone. It was approximately 120 ms on 7.04T. This result could thus be useful for studying bony tissue according to the SWIFT method in the future.

Background: Computed tomography (CT) is the gold standard imaging modality for the assessment of 3D bony morphology but incurs the cost of ionizing radiation exposure. High-resolution 3D magnetic resonance imaging (MRI) with CT-like bone contrast (CLBC) may provide an alternative to CT in allowing complete evaluation of both bony and soft tissue structures with a single MRI examination.
Purpose: To review the technical aspects of an optimized stack-of-stars 3D gradient recalled echo pulse sequence method (3D-Bone) in generating 3D MR images with CLBC, and to present a pictorial review of the utility of 3D-Bone in the clinical assessment of common musculoskeletal conditions.

Quantifying precision error for DXA, peripheral QCT (pQCT), and HR-pQCT is crucial for monitoring longitudinal changes in body composition and musculoskeletal outcomes. Agreement and associations between bone variables assessed using pQCT and second-generation HR-pQCT are unclear. This study aimed to determine the precision of, and agreement and associations between, bone variables assessed via DXA, pQCT, and second-generation HR-pQCT.

This study aimed to compare the failure rates of two different sizes of plates and screws to stabilize critical-sized (7 mm) femoral defects in male Sprague‒Dawley rats (aged 10 weeks). Femoral defects were stabilized with either a 4-hole plate (length 29 mm, thickness 1 mm, 10 rats, Group 1) and 4 cortical screws (diameter 2 mm) or with a 6-hole plate (length 30 mm, thickness 0.6 mm, 9 rats, Group 2) and 4 cortical screws (diameter 1.

Background: A bone stress injury (BSI) is a common overuse injury in collegiate athletes, particularly cross-country and track and field runners. Limited work describes the seasonality of BSIs or the differences in rates and anatomic locations of BSIs in collegiate runners.
Purpose: To describe seasonally related trends in anatomic locations of BSIs in National Collegiate Athletic Association (NCAA) Division I male and female middle- and long-distance runners.

Background: Ruptures of the distal biceps tendon (DBT) can affect the range of motion and strength of the elbow, raising concerns for patients seeking to restore normal function and engage in their regular activities, particularly returning to previous levels of sport participation.
Purpose: To characterize and assess the rate and timing of return to sport (RTS) after DBT repair.
Study Design: Systematic review; Level of evidence, 4.
