Three-dimensional Morphological Assessment of Adult Knee Menisci: A Computed Tomography-based Approach.

Aim: The present study aimed to examine meniscal morphology in an adult population in vivo through computed tomographic images, including research into morphological differences related to osteoarthritis, ageing and the meniscal location within the knee joint and a proposal for a supplementation of the current morphological classification.

Materials And Methods: Computed tomographic images of the knee for 118 patients were retrieved from the picture archiving and communication system of our Institute and included in this retrospective study. Each meniscus was subject to manual segmentation and converted into three-dimensional surfaces.

Bone marrow magnetic resonance imaging: physiologic and pathologic findings that radiologist should know.

Magnetic resonance imaging (MRI) plays a leading role in the non-invasive evaluation of bone marrow (BM). Normal BM pattern depends on the ratio and distribution of yellow and red marrow, which are subject to changes with age, pathologies, and treatments. Neonates show almost entirely red marrow.
