During her standby status, contrast-enhancement spiral CT was performed (Figure 1a⇓). Total occlusion of the left anterior descending coronary artery (segment 7) was observed by the CAG. Six days after successful direct PTCA, plain and Gd-enhancement T1-weighted MRI was performed (Figure 1b⇓). Three days after the PTCA, dual SPECT with 99m …
