We performed a
retrospective review of studies obtained using a prototype, self navigated,
free breathing 3D SSFP sequence. Scans were reviewed for diagnostic sensitivity of
coronary artery origin, diagnostic quality, and were graded for the severity of
respiratory or cardiac motion or blood pool inhomogeneity. A diagnostic scan was
obtained in 80.7% of cases. Blood pool inhomogeneity was common but very rarely
affected diagnosis. The greatest factor affecting diagnostic ability was
cardiac motion. We concluded that self-navigated 3D sequences can
provide excellent sensitivity in diagnosing coronary origins with
significant
time savings compared to diaphragm navigated sequences.
