Positioning for a PA chest x-ray Normal lateral chest radiograph. Different views (also known as projections) of the chest can be obtained by changing the relative orientation of the body and the direction of the x-ray beam. The most common views are posteroanterior, anteroposterior, and lateral. In a posteroanterior (PA) view, the x-ray source ...
A posterior-anterior (PA) chest X-ray is the standard view used; other views (lateral or lordotic) or CT scans may be necessary. [ citation needed ] In active pulmonary TB, infiltrates or consolidations and/or cavities are often seen in the upper lungs with or without mediastinal or hilar lymphadenopathy . [ 1 ]

Calcifications may be classified on whether there is mineral balance or not, and the location of the calcification. [3]
The cannonball sign is a radiological term used to describe the presence of multiple, well-circumscribed, round opacities seen on X-ray or CT imaging, typically in the lungs. [1] This finding is most commonly associated with hematogenous metastases, where malignant cells spread to the lungs via the bloodstream, forming discrete nodules that ...

Popcorn calcification or popcorn appearance is the radiological appearance of calcification with irregular rings and arcs, which resembles popcorns.The calcification patterns in chondroid lesions of the bone (such as enchondroma and chondrosarcoma), [1] pulmonary hamartomas, [2] degenerating fibroadenomas of the breast and calcified fibroids of the uterus have been described as 'popcorn ...

Aortic unfolding is an abnormality visible on a chest X-ray, that shows widening of the mediastinum which may mimic the appearance of a thoracic aortic aneurysm. [1]With aging, the ascending portion of the thoracic aorta increases in length by approximately 12% per decade, whereas the diameter increases by just 3% per decade.
