Intraluminal stent signal characterization by MRI is generally hampered by signal loss from the metallic stent material. This signal loss is related to magnetic susceptibility and RF shielding. Even when stent materials with low magnetic susceptibility are used, RF shielding can still be problematic. In this article we have shown that high flip angle imaging enables morphology assessment and tissue characterization in stents made of stainless steel 316L, NiTinol, and ABI-alloy.
磁共振成像（MRI）对腔内支架信号的特征描述通常会受到金属支架材料信号丢失的阻碍。这种信号丢失与磁敏感性和射频屏蔽有关。即使使用磁敏感性低的支架材料，射频屏蔽仍可能存在问题。在本文中，我们已经表明，高翻转角成像能够对由316L不锈钢、镍钛诺和ABI合金制成的支架进行形态学评估和组织特征描述。
