Aortic valve calcification
Aortic valve calcification can be an important incidental observation thoracic radiography or CT imaging. It is considered a marker for clinically significant aortic stenosis.
According to some reports aortic valve calcification may be prevalent as an incidental finding up to 18% of multi–detector CT scans dependent on study population 4.
On chest radiography, and the presence of such calcifications are usually best seen on the lateral radiograph 1.
ECD gated CT scans are best at assessment and quantification
Some authors suggest aortic valve calcification should always be commented upon in the radiology reports 6.
