[FIGURE 1 OMITTED] [FIGURE 2 OMITTED] In retrospective analysis, note early myocardial retained Gadolinium in the short axis CINE SSFP acquisition (Figure 1), corresponding to regions of abnormal DHE.
[FIGURE 4 OMITTED] A CMR radiological investigation typically involves the following MRI sequences: * coronal and axial black-blood fast spin echo sequence for assessing extra-cardiac abnormalities * a short axis 'stack' of cine bSSFP images to assess myocardial function; about a dozen slices are acquired, spanning the entire heart from the base to the apex * two- and four-chamber cine bSSFP images to assess myocardial function and valvular function * short- and long-axis inversion recovery delayed-enhancement sequences to identify infarcted myocardial tissue * short- and long-axis T1-weighted images may be added to investigate the distribution of intramyocardial fat * short- and long-axis T2-weighted images may be added for distinguishing oedema.
This orientation is favorable for two reasons: (1) aesthetically, it creates a smoother transition from the tip-defining points to the alar lobule, and (2) functionally, if the lateral crura are nearly perpendicular to the septum, the scroll no longer acts as a hinge and it is difficult for the forces of inspiration to compress the cartilage along its short axis.
