Diffusion Tensor Imaging (DTI) of Brachial Plexus

Diffusion Tensor Imaging (DTI) of Brachial Plexus

Diffusion is the random, thermally-induced, microscopic water motion within a tissue, well known as Brownian motion. Diffusion Tensor Imaging (DTI) is an extension of Diffusion-Weighted Imaging (DWI) that takes into account and measures the anisotropic diffusion (nerves are highly anisotropic). DTI can be useful in MR Neurography of the brachial plexus, offering functional information (can …

Types of Sutures, Stitches, and Staples Medical

Types of Sutures, Stitches, and Staples Medical

Types of Sutures and Stitches Sutures can be either absorbable or nonabsorbable. Absorbable sutures are intended to be broken down by the body over time and eventually dissolve completely. Some materials used to make absorbable sutures are derived from animal products that have been specially processed. Other absorbable sutures are made from synthetic polymer materials …

Surface Anatomy of Forearm Muscles

Surface Anatomy of Forearm Muscles

Muscles in the Anterior Compartment of the Forearm There are many muscles in the forearm. In the anterior compartment, they are split into three categories; superficial, intermediate and deep. In general, muscles in the anterior compartment of the forearm perform flexion at the wrist and fingers, and pronation.

Surface Representation of the Spaces of Arm: Triangular and Quadrangular spaces

Three important spaces of the shoulder that are bordered by the triceps include. quadrangular space; triangular space; triangular interval. Boundaries and contents of the spaces 1. Quadrangular space They are paired, quadrangular shaped spaces seen near the axillary region. The space is mainly formed by the triceps muscle and the humerus. Hence it is also called foramen humero-tricipitale. Boundaries of the …
