Hình ảnh cộng hưởng từ dòng chảy bốn chiều trong khảo sát động mạch cảnh và động mạch não
Nội dung chính của bài viết
Tóm tắt
Cộng hưởng từ dòng chảy bốn chiều dựa trên ứng dụng của cộng hưởng từ tương phản pha, cung cấp khả năng trực quan hóa và định lượng lưu lượng dòng chảy trong cơ thể. Bài viết thông qua các tình huống lâm sàng cụ thể khảo sát huyết động của động mạch cảnh và động mạch não, cho thấy cộng hưởng từ dòng chảy bốn chiều có tiềm năng hỗ trợ cho kỹ thuật chẩn đoán hình ảnh mạch máu thường quy, giúp có cái nhìn sâu sắc hơn về mối liên hệ giữa thay đổi huyết động học và các bệnh lý xơ vữa động mạch hay đột quỵ.
Từ khóa
cộng hưởng từ (CHT), cộng hưởng từ dòng chảy bốn chiều (CHT-DC-4C), đột qụy, xơ vữa động mạch
