Spaceflight-induced cerebral changes, or microgravity-induced cerebral changes, refer to the effects of prolonged microgravity exposure, through spaceflight, on the brain and surrounding structures. As the name suggests, spaceflight-induced cerebral changes are limited to patients who have experienced spaceflight and microgravity, i.e. astronauts. Therefore, patients with these changes are not likely to be encountered in the vast majority of radiology departments.

Scaphoid non-union is one of the complications of scaphoid fracture because of the unique anatomy of the scaphoid and its vascular supply. Scaphoid fractures have one of the highest rates non-union of all fractures at ~10% (range 5-15%) 3,4. Scaphoid non-union occurs most commonly through the middle or proximal thirds 1.

The scaphoid series is comprised of posteroanterior, oblique, lateral and angled posteroanterior projections. The series examines the carpal bones focussed mainly on the scaphoid. It also examines the radiocarpal and distal radioulnar joints along with the distal radius and ulna. Scaphoid fractures are often a result of FOOSH injuries and have a bad prognosis if missed (risk of avascular necrosis of proximal aspect in scaphoid waist fracture).

Gynecomastia refers to a benign excess of the male breast tissue, that is usually reversible. It is not a risk factor per se for developing male breast cancer. While it can occur at any age, it tends to have greater prevalence in two groups: adolescent boys and older men (some publications describe a trimodal age distribution, occurring in neonatal, pubertal, and elderly males 8).

Acute aortic syndrome describes the presentation of patients with one of a number of life-threatening aortic pathologies that give rise to similar clinical presentations. Exactly which entities are included under the umbrella term acute aortic syndrome varies somewhat from publication to publication. Three conditions are generally included, sharing epidemiological and clinical presentation as well as having overlapping and sometimes co-existing imaging features 1-5.
