OBJECTIVE. The purposes of this article are to explore the potential for use of CT angiography and MRI and to highlight data suggestive of their usefulness in specific cardiovascular abnormalities. CONCLUSION. The evaluation of stroke requires comprehensive assessment of potential stroke mechanisms, including cardiac sources. Despite an exhaustive search for secondary causes, the precise cause of many strokes remains unknown (cryptogenic). It is well recognized, however, that some of these potential causes occur as a result of embolism from the heart or great vessels. Thus, echocardiography, in particular transesophageal echocardiography, is instrumental in a careful assessment of cardiac causes in selected individuals. Unfortunately, transesophageal echocardiography is invasive, and some patients may have relative or absolute contraindications. Cardiovascular CT angiography and MRI have growing potential compared with conventional cardiovascular echography.
目的。本文的目的是探讨CT血管造影和MRI的应用潜力，并强调提示它们在特定心血管异常中有用性的数据。结论。对中风的评估需要对潜在的中风机制进行全面评估，包括心脏来源。尽管对继发性病因进行了详尽的搜索，但许多中风的确切病因仍然不明（隐源性）。然而，众所周知，其中一些潜在病因是由心脏或大血管栓塞引起的。因此，超声心动图，特别是经食管超声心动图，在仔细评估特定个体的心脏病因方面很有帮助。不幸的是，经食管超声心动图是有创的，一些患者可能有相对或绝对的禁忌症。与传统的心血管超声检查相比，心血管CT血管造影和MRI的应用潜力越来越大。
