MR coronary angiography using 3D-SSFP with and without contrast application.
We compared the performance of a contrast-enhanced with a non-contrast breath-hold 3D-SSFP-sequence for Magnetic Resonance Coronary Angiography in seven healthy subjects and 14 patients. Visibility of coronary segments, vessel length, image quality and the influence of an extracellular contrast agent (Gadolinium-DTPA) were assessed. Overall, the performance of the sequence was better in healthy subjects than in patients. Although the application of Gadolinium-DTPA increased the contrast-to-noise-ratio of the right coronary artery, the overall performance was not significantly improved. We conclude that a 3D-SSFP-technique depicts extensive parts of the coronary arteries and does not require contrast application.
