To evaluate the use of noncontrast-enhanced coronary magnetic resonance angiography (NC-CMRA) for long-term follow-up in patients with Kawasaki disease (KD). In total, 40 (77 aneurysms) patients with KD who underwent NC-CMRA were retrospectively analyzed. Coronary artery aneurysms and dilations observed during the acute phase were classified into three groups according to their diameter based on the American Heart Association criteria.

- Kawasaki disease is a systemic vasculitis that requires the evaluation of both coronary and systemic arteries, and this study aimed to assess the effectiveness of non-contrast magnetic resonance angiography (NC-MRA) in detecting complications related to the disease.* -
- The study involved 28 patients, with 57 exams focused on coronary arteries and 42 exams that included both coronary and systemic artery assessments, finding high image quality for various systemic arteries.* -
- Results showed no significant differences in examination time or sedation dosages between protocols and identified systemic artery aneurysms in 7.1% of patients, demonstrating the feasibility of a combined examination approach.*
Article Synopsis
- Kawasaki disease (KD) causes aneurysms in coronary and systemic arteries, which can complicate diagnosis and treatment.
- A case study of a 12-year-old diagnosed with KD highlighted imaging issues using ECG-gated 3D FSE magnetic resonance imaging during aneurysm evaluation.
- The study found that while the technique identified some aneurysms, it led to signal loss in others and reduced image quality for peripheral arteries, making detection challenging.
Article Synopsis
- Kawasaki disease (KD) can lead to coronary aneurysms and sometimes systemic artery aneurysms (SAAs), necessitating evaluation for both types.
- Two cases are reported, one involving a 1-year-old with multiple axillary artery aneurysms and the other a 13-year-old with a single aneurysm, both diagnosed with KD at an early age.
- The study highlights that electrocardiogram-gated three-dimensional fast spin echo imaging can effectively assess SAAs in KD patients without the need for long scanning times or contrast agents.
