    Acute and Stress-related Injuries of Bone and Cartilage: Pertinent Anatomy, Basic Biomechanics, and Imaging Perspective

    Knowledge of the macroscopic and microscopic anatomy and basic biomechanics of bone and cartilage provides the foundation for a better understanding of the manner in which this tissue responds to altered mechanical forces and sheds light on the imaging appearances associated with both acute and repetitive injury.

    In a State-of-the-Art article in the July issue of Radiology (RSNA.org/Radiology), Mini N. Pathria, MD, and Christine B. Chung, MD, of the University of California San Diego (UCSD) Medical Center, and Donald L. Resnick, MD, of the UCSD Teleradiology and Education Center, review the embryology and macroscopic and microscopic anatomy. Researchers also address basic biomechanical principles that explain the patterns of failure occurring in the cartilage, subchondral bone plate, and cortical and cancellous bone that are encountered clinically.

    “Thorough knowledge of the anatomy, physiology and biomechanics of normal bone and cartilage serves as a prerequisite to a full understanding of both the manner in which these tissues adapt to physiologic stresses and the patterns of tissue failure that develop under abnormal conditions,” the authors write.

    Bariatric CT Imaging: Challenges and Solutions

    The obesity epidemic in the adult and pediatric populations affects all aspects of healthcare, including diagnostic imaging.

    In an article published in the July-August issue of RadioGraphics (RSNA.org/RadioGraphics), Dzmitry M. Fursevich, MD, of Florida Hospital in Orlando, and colleagues explain the physical limitations to accommodating bariatric patients in CT suites, describe commonly encountered CT artifacts at bariatric imaging, and discuss the pitfalls in acquiring contrast-enhanced CT images of bariatric patients.

    “With the increasing prevalence of obese and morbidly obese patients, bariatric CT imaging is becoming common in day-to-day radiology practice, and a basic understanding of the unique problems that bariatric patients pose to the imaging community is crucial in any setting,” the authors write.

    Radiology Podcasts

    Listen to Radiology Editor Herbert Y. Kressel, M.D., deputy editors and authors discuss the following articles in the December issue of Radiology at RSNA.org/Radiology-Podcasts.

    • “Association between Hepatic Triglyceride Content and Left Ventricular Diastolic Function in a Population-based Cohort: The Netherlands Epidemiology of Obesity Study,” Ralph L. Widya, MD, and colleagues.

    • “Indirect Cost and Harm Attributable to Oral 13-Hour Inpatient Corticosteroid Prophylaxis before Contrast-enhanced CT,” Matthew S. Davenport, MD, and colleagues.

    • “White Matter Degeneration with Aging: Longitudinal Diffusion MR Imaging Analysis,” Marius de Groot, MSC, and colleagues.

    Longitudinal histologic section of a developing proximal femur from a third-trimester fetus illustrating from superior to inferior cartilaginous epiphysis with developing secondary ossification center of the femoral head (curved arrow), the entire growth plate (straight arrow), and the metaphysis and proximal diaphysis containing the primary ossification center (Hematoxylin- eosin stain, low magnification).

    Axial CT image of a morbidly obese 75-year-old woman shows the cropping artifact. Subcutaneous soft tissues and the right abdominal wall were excluded from the reconstruction field of view. A ventral hernia (arrow) at the periphery of the image was nearly missed.
