Update on MR Imaging Techniques of the Hip.

MR imaging protocols and technical parameters should be optimized in order to achieve the best diagnostic results. Routine hip MR imaging includes a combination of T1-weighted and fluid-sensitive sequences, obtained in coronal, axial, and sagittal planes. MR arthrography of the hip can be used for assessment of intra-articular pathology involving intricate and signal-poor structures such as articular cartilage, labral fibrocartilage, and intra-articular bodies.

MRI and Anatomical Determinants Affecting Neuroforaminal Stenosis Evaluation: A Descriptive Observational Study.

Purpose: Neuroforaminal stenosis (NFS), a narrowing of the intervertebral foramen, is a cause of disability in the aging population. Formal magnetic resonance imaging (MRI) classification of NSF has been developed recently and contradictory findings have been reported. This study aims to assess whether in-plane, anatomically conformed two-dimensional (2D) views of the neuroforamen characterize NFS more accurately than traditional axial, coronal, and sagittal views in healthy individuals with and without simulated scoliosis.

Racial Differences in Iliac Crest Cancellous Bone Composition: Implications for Preoperative Planning in Spinal Fusion Procedures.

Study Design: This was a retrospective cohort study.

Objective: The objective of this study was to determine whether race, specifically American white and American black, correlates with the ratio of cancellous to total bone at the iliac crest.

Summary Of Background Data: Studies have demonstrated higher proximal femur bone density in American blacks than American whites.

Biochemical magnetic resonance imaging of knee articular cartilage: T1rho and T2 mapping as cartilage degeneration biomarkers.

Osteoarthritis (OA) is a disease whose hallmark is the degeneration of articular cartilage. There is a worsening epidemic of OA in the United States today, with considerable economic costs. In order to develop more effective treatments for OA, noninvasive biomarkers that permit early diagnosis and treatment monitoring are necessary.
