Vergleich neuer Sequenzen in der Magnetresonanz-Koronarangiographie

At the moment coronary magnetic resonance angiography (corMRA) is still in research. To get more information about the potential of this non invasive method of diagnosis we compared four corMRA sequences. The sequence we used for reference sequence is the only one which has been investigated in a validated study so far. The three sequences we used for comparison have already been successfully technically implemented in former studies. With respect to the usual comparison criteria this study showed that none of the four sequences turned out as a generally outstanding sequence. However, differentiated interpretation of the comparison criteria allowed the conclusion that the reference sequence (Standard T2 Prepared 3D Gradient-Echo Sequence) could not reach the performance of two other sequences (two T2 Prepared 3D SSFP Sequences, one with cartesian and the other one with radial k-space sampling). In particular, radial k-space sampling could solve the currently largest problem in corMRA, the suppression of motion artifacts. Therefore we can surely expect new studies with improvement of these promising sequences.
