Articular cartilage in the knee: current MR imaging techniques and applications in clinical practice and research.
Magnetic resonance (MR) imaging is the most important imaging modality for the evaluation of traumatic or degenerative cartilaginous lesions in the knee. It is a powerful noninvasive tool for…

Bone marrow fat composition as a novel imaging biomarker in postmenopausal women with prevalent fragility fractures
TLDR
It is suggested that altered bone marrow fat composition is linked with fragility fractures and diabetes and MRS of spinal bone marrowfat may serve as a novel tool for BMD‐independent fracture risk assessment.

Increased cortical porosity in type 2 diabetic postmenopausal women with fragility fractures
TLDR
It is suggested that severe deficits in cortical bone quality are responsible for fragility fractures in postmenopausal diabetic women.

Does vertebral bone marrow fat content correlate with abdominal adipose tissue, lumbar spine bone mineral density, and blood biomarkers in women with type 2 diabetes mellitus?
To compare vertebral bone marrow fat content quantified with proton MR spectroscopy (1H‐MRS) with the volume of abdominal adipose tissue, lumbar spine volumetric bone mineral density (vBMD), and…

Texture analysis of cartilage T2 maps: individuals with risk factors for OA have higher and more heterogeneous knee cartilage MR T2 compared to normal controls - data from the osteoarthritis…
TLDR
It is demonstrated that subjects at risk for OA have both higher and more heterogeneous cartilage T2 values than controls, and that T2 parameters are associated with morphologic degeneration.

Bone marrow fat quantification in the presence of trabecular bone: Initial comparison between water‐fat imaging and single‐voxel MRS
The purpose of the present study was to test the relative performance of chemical shift‐based water‐fat imaging in measuring bone marrow fat fraction in the presence of trabecular bone, having as…

Obesity increases the prevalence and severity of focal knee abnormalities diagnosed using 3T MRI in middle-aged subjects—data from the Osteoarthritis Initiative
TLDR
Obesity was associated with both higher prevalence and severity of early degenerative changes in the knee in middle-aged individuals without radiographic OA and with significantly increased cartilage lesion progression (of any grade) over 36 months.

Quantitative MRI and spectroscopy of bone marrow
TLDR
A large selection of studies published until March 2017 in proton‐based quantitative MRI and MRS of bone marrow affected by osteoporosis, fractures, metabolic diseases, multiple myeloma, and bone metastases are summarized.

Meniscal T1rho and T2 measured with 3.0T MRI increases directly after running a marathon
TLDR
T2 values in menisci have the potential to be used as biomarkers for identifying reversible meniscus matrix changes indicating potential tissue damage, and T1rho values need further study, but may be a valuable marker for diagnosing early, degenerative changes in theMenisci following exercise.

Opportunistic osteoporosis screening in multi-detector CT images via local classification of textures
TLDR
The presented classifier combining 3D texture features and regional vBMD including the complete thoracolumbar spine showed high discriminatory power to identify patients with vertebral fractures and had a better diagnostic performance than v BMD alone.
