Figure 10. Leaflet valve. T2-weighted fast spin-echo silicone-suppressed MR image (original magnification, x5) of the distal part of the leaflet valve of a Surgitek standard double-lumen implant such as that shown in Figure 9, showing the characteristic appearance of the leaflet valve in cross section. (This cross section is what would be seen at about the location of the thick arrow in Figure 9). In this image the inner-lumen silicone gel is dark and the outer-lumen saline surrounding the leaflet valve is bright. Another more distal (en face) MR cross section through this same type of valve is shown in Figure 11.
