title: Chest film detection of coronary artery calcification. The value of the CAC triangle.
abstract: Eighty-six adult patients were studied by PA chest film and fluoroscopy for coronary artery calcification (CAC). A triangular area (CAC triangle) along the left mid-heart border of the PA chest film was used in identifying CAC. Of 57 patients, 24 (42%) with CAC observed fluoroscopically had a strongly suspected or positive CAC triangle. The CAC triangle in the PA chest film has proved useful in identifying coronary artery calcification on the plain film.
