In our institution, we currently use a Siemens 1.5T MAGNETOM® Avanto system (Siemens Healthineers, Erlangen, Germany), with head, neck and spine matrix coils, and a body ABSTRACT Adult-onset brachial plexopathy can be classifi ed into traumatic and non-traumatic aetiologies. Traumatic brachial plexopathies can affect the pre-or postganglionic segments of the plexus. Non-traumatic brachial plexopathies may be due to neoplasia, radiotherapy, thoracic outlet syndrome and idiopathic neuralgic amyotrophy. Conventional magnetic resonance imaging (MRI) is useful to localise the area of injury or disease, and identify the likely cause. This review discusses some of the common causes of adult-onset brachial plexopathy and their imaging features on MRI. We also present a series of cases to illustrate some of these causes and their MRI fi ndings.

Foot and ankle injuries are very common, particularly among young active athletic individuals. MR imaging has become one of the modalities of choice in the assessment of foot and ankle injuries. Accurate interpretation of MR images and diagnosis of pathology requires familiarity with normal anatomical variants and common diagnostic pitfalls. This article describes the common anatomical variants and technical pitfalls in MR imaging of the foot and ankle.
