In addition, QCT can avoid the artificially high BMD measurements that can confuse the results from DXA in arthritic patients, patients who are obese, [9] who suffer from disc space narrowing or spinal degenerative diseases, [10] aortic calcification [11] or osteophytes. [12]
Calcification is the accumulation of calcium salts in a body tissue. It normally occurs in the formation of bone, but calcium can be deposited abnormally in soft tissue, [1] [2] causing it to harden. Calcifications may be classified on whether there is mineral balance or not, and the location of the calcification. [3]
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.
The existence of Mönckeberg's arteriosclerosis has been disputed and it has been proposed that it is a part of a continuum of atherosclerotic disease: [19] the majority of atherosclerotic plaques contain some calcium deposits [23] [24] and calcification of the internal elastic lamina is common in pathological specimens labelled as Mönckeberg ...

Dystrophic calcification (DC) is the calcification occurring in degenerated or necrotic tissue, as in hyalinized scars, degenerated foci in leiomyomas, and caseous nodules. This occurs as a reaction to tissue damage, [ 1 ] including as a consequence of medical device implantation.

Finally, in calcific aortic stenosis [17] [18] at least, the calcification in and around the aortic valve can progress and extend to involve the electrical conduction system of the heart. If that occurs, the result may be heart block, a potentially lethal condition of which syncope may be a symptom. [citation needed]
