The aim of this exhibit is familiarise the reader with basic and advanced finger anatomy and pathology commonly encountered utilising MRI microscopy coils.
This is an examination commonly requested but poorly analysed by the reporting radiologist.
This is an attempt to educate those involved in the reading of such cases.
The advances in MRI technology and finger microscopy coils has allowed direct visualisation of structures previously unseen.
This includes the volar plate, the true and accessory collateral ligaments and the beak ligament of the thumb.This exhibit describes the hardware required,imaging planes and sequences required to comprehensively evaluate a finger joint following trauma. The template for reporting on such cases will be described complemented by normal anatomy and examples of pathology.
The reader should be able set up a protocol and be proficient in the reading of MRI of the traumatic finger.
The presentation will refresh the anatomy of the finger and provide examples of pathology for them to compare with their cases.
They will be aware of potential pitfall relating to the magic angle which are commonly encountered.
Injuries to the beak ligament of the thumb will be described an often poorly understood structure of extreme importance in the stability of the thumb.
