+    This demo showcases GANcMRI: Synthetic cardiac MRI generation.Upon starting the demo or refreshing the page, a unique video will be automatically generated based on two methods described in our paper: ED-to-ES and Frame-to-Frame. These methods simulate cardiac function and movement in a realistic manner. The demo includes interactive sliders that allow you to adjust two parameters:
+
+    1. **Sphericity Index:** This slider controls the sphericity of the left ventricle in the generated video. [The sphericity index](https://www.cell.com/med/pdf/S2666-6340(23)00069-7.pdf) is a measure of how spherical (round) the left ventricle appears, which is an important aspect in assessing certain heart conditions.
+    2. **Left Ventricular Volume:** With this slider, you can modify the size of the left ventricle.
