MRI of the full physique units out to coach trainee and skilled radiologists, radiographers and clinicians concerning key sequences for optimum imaging of universal pathologies, with easy motives at the selection of a selected MR series. The authors current general and consultant examples with correct medical and imaging positive aspects to help a greater realizing of those generally encountered stipulations. each unit starts off with a brief anatomy evaluate, and every case is defined in a standardised layout with a medical heritage, key sequences, imaging positive factors, and functional tricks as to shut differentials and how you can distinguish among them. A textual content of this nature is key for all MR practitioners no matter what their historical past: clinical, technical or medical.

Key sequences Posterolateral complex injury is often associated with ACL injuries. Fractures associated with this type of injury include: • Segond fractures • avulsion fracture of the proximal fibula: the ‘arcuate fracture’ • fracture of the insertion of the ilio-tibial band: ’Gerdy’s tubercle’. Hints and tips Injuries of the posterolateral corner are often missed. Any fluid signal in or around tendons should alert to its possibility. • PD-weighted FS and STIR/T2-weighted FS ACL or PCL tears are often associated with posterolateral corner injuries.
The position of the cyst corresponds to the site of the tear. Fat atrophy of the rotator cuff muscles indicates a nerve entrapment syndrome. Hints and tips T2-weighted axial images are useful to visualize both the cyst and the tear. Cysts are often associated with labral tears. The site of the cyst corresponds to the site of the tear. For example, a cyst in the suprascapular notch may show a SLAP tear. Key sequences • T2-weighted axial for the site of the lesion and often the tear • FS T1-weighted sagittal and axial for arthrography Imaging findings A paralabral cyst is usually high signal on fluid-sensitive sequences, although if it contains proteinaceous material, it may be high signal on T1-weighted sequences.
