[Value of multislice spiral CT in the diagnosis of anomalous origin of the coronary arteries].
OBJECTIVE
To investigate the value of multislice spiral CT (MSCT) coronary angiography in the diagnosis of anomalous origin of coronary arteries.


METHODS
5000 patients diagnosed or suspected as with diseases of coronary artery underwent MSCT coronary angiography (retrospectively ECG-gating; 0.5 s rotation; one-sector or two-sector reconstruction algorithm; intravenous contrast agent) 2001-2005.


RESULTS
Anomalous origin of coronary artery was incidentally found with multislice spiral CT in 39 patients (0.78%), including anomalously high origin of the right coronary artery (n = 20), anomalous origin of the right coronary artery from left coronary sinus (n = 11), aberrant circumflex artery arises from the right coronary sinus or right coronary (n = 3), anomalous origin of the right coronary artery from the posterior coronary sinus (n = 1), anomalous origin of the left coronary artery from the posterior coronary sinus (n = 1), single coronary artery (n = 2), separate origin of circumflex and left anterior descending arteries from left coronary sinus (n = 1). These signs were better shown by MSCT coronary angiography.


CONCLUSIONS
MSCT coronary angiography is a useful adjunctive technique to invasive coronary angiography in the diagnosis of anomalous origin of coronary arteries.
