Calcaneal inclination angle
The calcaneal inclination angle, also known as the calcaneal pitch, is useful in assessing medial arch height.
Measurement
This angle is formed on a weight-bearing lateral foot radiograph between the calcaneal inclination axis (i.e. most inferior part of the calcaneus) and the supporting hori...

Maxillary sinus
The maxillary sinus (or antrum of Highmore) is a paired pyramid-shaped paranasal sinus within the maxillary bone which drains via the maxillary ostium into the infundibulum, then through hiatus semilunaris into the middle meatus. It is the largest of the paranasal sinuses.
Summary

Meary's angle
Meary's angle or the (lateral) talus-first metatarsal angle has been used to identify the apex of deformity in patients with pes cavus and pes planus on lateral weight-bearing foot radiographs.
Measurement
It is the angle between a line drawn along the longitudinal axes of the talus (mid-talar...

Coumadin ridge
A coumadin ridge, also called warfarin ridge or left lateral ridge, is a band-like embryological remnant in the left atrium between the left superior pulmonary vein and the left atrial appendage. It is considered an anatomical variant.
The ridge is formed by the coalition of the left superior ...

Barium aspiration
Barium aspiration occurs occasionally during upper GI fluoroscopic studies using barium sulfate contrast, and usually only small amounts pass into the airways.
Clinical presentation
When only tiny quantities of barium pass into the airways (so-called microaspiration) the patient may remain asy...
