Carpal tendon sheaths: describes the various synovial sheaths surrounding the tendons of the wrist tendon: sheath of the extensor muscles of the fingers, sheath of the flexor carpi radialis, tendon sheath of the long thumb flexor. The carpal tunnel and ulnar canal (Guyon's) are visible by selecting the different filters on "Anatomical parts". Fascia / aponeuroses: notably displays the transverse carpal ligament (flexor retinaculum) and the palmar fascia. Tendons: the many tendons of the wrist are all labeled on this picture, from the tendon of the flexor carpi radials to the flexor digitorum profundus tendon. Muscles: mainly the muscles of the forearm and the palmar region (muscles of the little finger, thumb muscles). Ligaments: all the ligaments of the wrist visible on an MRI are shown on this anatomy module, including collateral ligaments, the radiocarpal and ulnocarpal ligaments as well as the intercarpal ligaments. Articulation: the different joints of the carpus, including the distal radioulnar joint, the radiocarpal, midcarpal and carpometacarpal articulations.Īnatomy of the wrist on 3T MR (axial, sagittal and coronal slices) and 3D views of the carpal bones : Wrist joint, Midcarpal joint, Carpometacarpal joints. Bone: the anatomy of the bones of the wrist, subdivided into radius, ulna, carpal bones (scaphoid, lunate, pisiform, triquetrum, hamatum, capitatum, trapezoid and trapezium) and the metacarpal bones. General anatomy: the different regions of the wrist and hand (carpal, metacarpal, hypothenar and thenar eminence). Labels for the anatomical structures of the carpusģ40 anatomical structures of the wrist were labeled, accessible on "Anatomical parts": The 3D images of the wrist joint and carpal bones are three-dimensional reconstructions obtained from a scanner. We used the commonly used weightings (and RFP-FatSat T1) and impacts (axial, coronal and sagittal) in medical imaging studies of the wrist. 
Image acquisition was performed on a 3 Tesla MRI with a thickness of 4 mm in contiguous sections. The MRI images of the elbow are from a healthy volunteer.
This module is a support to learn and on a daily practice of magnetic resonance imaging of the wrist, useful for a specialized audience (radiologists, surgeons, rheumatologists and physicians specializing in musculoskeletal imaging). On this module on the anatomy of the wrist in 3T MRI, we labeled over 340 anatomical structures in 208 MR images of the wrist and 3D reconstructions of the carpal bones.Īnatomy of the wrist (MR) : Carpal tunnel - Ulnar canal Images provided by Sorin Ghiea & Emi Preda - MD
