The ultrasound "U" classification of thyroid nodules has been developed by the British Thyroid Association (BTA) as part of their 2014 guidelines on the management of thyroid cancer 1. It allows for the stratification of thyroid nodules as benign, suspicious or malignant based on ultrasound appearances termed U1-U5. This is used to aid further investigation and management.

The extrusion index, also known as the(Reimers) hip migration index, is a radiographic measurement of femoral head bony coverage by the acetabulum. It is useful in assessing for developmental dysplasia of the hip, femoroacetabular impingement, and assessment of hip subluxation in cerebral palsy. It is calculated by dividing the horizontal distance of the lateral femoral head that is uncovered by the acetabulum by the total horizontal distance or width of the femoral head.

Tubulinopathies refer to a wide spectrum of cortical malformations that result from defects in genes encoding the tubulin protein that regulates neuronal migration during brain development. Some series report a high prevalence of seizures during infancy which may be the initial reason for brain imaging in patients with tubulin disorders. They may also be encountered in children with developmental delays. Tubulins play an important role in neuronal migration in the developing fetal brain.

Glenohumeral (shoulder) arthrography is an imaging technique used to evaluate the glenohumeral joint to evaluate the joint components. A glenohumeral joint injection is usually performed under fluoroscopic guidance although ultrasound and CT can be also be used. An alternative to direct arthrography (where contrast is injected into the joint) is indirect arthrography. Historically arthrograms were performed with fluoroscopy and plain radiographs only.
