- W2355990562 abstract "Objective To prospectively compare the image quality and feasibility between 3D BTFE and dual-IR TSE sequence. Materials and Methods Twenty-eight cases received both the navigator-gated 3D BTFE and dual-IR TSE sequences. Postprocess reconstruction ways included maximum and minimum intensity projection. Statistical analysis was performed in image quality score≥2. Signal-to-noise ratio(SNR),contrast-to-noise ratio(CNR),scores of image quality and length of targed vessel were assessed among two sequences.Data were analyzed for statistical differences by using the matched-pairs student T test. Results (1) Artifacts could be reduced by VCG trigger combined with real-time respiratory navigator gating and tracking; (2) Targed vessels were clearly depicted by both the navigator-gated 3D BTFE and dual-IR TSE sequences; (3) Lengths of RCA,LM,LAD,LCX of 3D BTFE and dual-IR TSE sequence were 97.38/89.14,15.34/14.19、52.50/35.41 and 50.92/49.16 mm respectively,SNR,CNR and scores of image quality were 108.86/4.66,67.77/28.01 and 3.50/2.54 respectively. Conclusion VCG trigger combined with real-time respiratory navigator gating and tracking can obtain the image of coronary artery reliably. CMRA with 3D BTFE is more feasible and the image quality is better." @default.
