HCM patient with myocardial crypts in the anteroseptal region.

<p>Upper row: 3-chamber view with different techniques, Bottom row: short axis view using the same techniques, A and B CINE images at 3.0T, C and D Late Gadolinium Enhancement at 3.0T, E and F CINE images at 7.0T, G and H CINE images at 1.5 T CMR, I and J Fat-Water images, Single arrows indicates LGE at 3.0T, Double arrow displays myocardial crypt at 7.0T.</p

Case example: Patient with myocardial crypts.

<p>In the top row fibrosis imaging (LGE at 3.0T) is shown. The yellow arrow indicates the fibrosis (A long axis view B short axis view). In the bottom row cine imaging at 7.0T is shown The red arrow indicates the myocardial crypts (A long axis view B short axis view). Remarkable, fibrosis and crypts have a certain overlap. One may assume, that the bright signal at 3.0T might be also induced by blood within the crypts.</p

Feasibility of CMR in HCM patients at 7.0T.

<p>High Resolution CINE images of each patient (slice thickness 2.5 mm) All images were evaluable as shown by these two-chamber views, but the quality scoring revealed differences. A-H) Examples with a good images quality and mild artifacts. I-M) Images with different types of artifacts</p

Distribution and prevalence of fibrosis and crypts.

<p>Myocardial crypts were only located in the regions with fibrosis as identified by LGE at 3.0T</p

Comparison of left ventricular function between the different field strengths.

<p>The comparison of left ventricular function revealed no ignificant differences between the field strengths, Top: Left ventricular function at 3.0 T (biplanar versus short axis). Bottom: Left ventricular function at 7.0 T compared to 3.0 T (both biplanar).</p
