“…Using digital subtraction Detrano et al described improved detection of moving structures (i.e., calcified segments of coronary artery) during fluoroscopy by subtracting stationary calcified structures such as the ribs and spine [20]. Digital subtraction fluoroscopy was more accurate in younger than in older patients, had higher interobserver agreement [21] and provided semiquantitative assessment of CAC [22]. The technique, however, has not gained widespread application mainly 3.…”

“…Methods such as spiral cr [5], electron beam CT [6,7], digital subtraction fluoroscopy [8], and intravascular ultrasound [9,10] have been used to detect this "indicator" calcification, either directly in the coronaries or in indicator arteries such as the brachials, carotids, or illiacs [II]. The nonzero threshold for CT detection of calcium (2 mm 2 [12]) produces a high negative predictive value for greater than 50% stenosis but relatively low positive predictive value [13].…”

“…125 Η ψηφιακή ακτινοσκόπηση διπλής ενέργειας με τη δυνατότητα αφαίρεσης εικόνας αναδείχθηκε σε αρκετές ακόμα μελέτες ως μέθοδος υψηλότερης διαγνωστικής ακρίβειας συκρινόμενη με τα συστήματα συμβατικής απεικόνισης, με υψηλότερη συμφωνία για δύο διαφορετικούς παρατηρητές (interobserver agreement). 127,128 Ωστόσο, η μεθοδος δεν εφαρμόστηκε ευρέως κυρίως εξαιτίας της περιορισμένης διαθεσιμότητας των συστημάτων αυτών.! Επίσης, η ανίχνευση ασβέστωσης με συμβατική ψηφιακή ακτινοσκόπηση εμφάνισε συσχέτιση με τα καρδιαγγειακά συμβάντα σε μια προοπτική μελέτη 425 ασυμπωματικών ατόμων χαμηλού κινδύνου.…”
