Proximally: distal radioulnar joint levelĭistally: palmar radiocarpal ligament level Intermediate signal: muscles, ligaments, blood vessels, nervesįat saturation, contrast, proton density MRI Low signal (hypointensity): fluid, cartilage, cortical bone High signal (hyperintensity): fat, contrast (gadolinium), bone marrow Key facts about wrist MRI MRI basisĬreation of 2D and 3D images by exploiting the proton density (hydrogen ions) of various tissues These make it a perfect investigational tool for radiocarpal joint anatomy and pathology. As a result, MRI is safe (no ionizing radiation), has the best soft tissue contrast resolution and image quality is not degraded by the presence of bone or air. This technique uses magnetic fields and radio waves to distinguish between the nuclear magnetic properties of various tissues. The imaging method that best deals with such complexity is the magnetic resonance imaging (MRI). Therefore, this compact region contains many small and detailed anatomical structures that can be quite challenging to distinguish radiologically. The radiocarpal joint is reinforced by several ligaments and provides the passage for many soft tissues and neurovascular structures on their way towards the hand. It is formed by the apposition of the radius and three proximal carpal bones: scaphoid, lunate and triquetrum. The radiocarpal joint, more commonly known as the wrist, is the articulation between the distal forearm and the hand. ![]()
