“…Magnetic resonance imaging (MRI) is a modality that allows CA evaluation without the invasiveness of contrast media and radiation exposure, 18 which is useful for evaluating CAAs in patients with KD 19,20 . We have reported the usefulness of systemic artery (SA) imaging using electrocardiogram (ECG)‐gated three‐dimensional (3D) fast spin echo (FSE) in the diastolic phase for SAA evaluation 21,22 . This imaging method can capture SAAs quickly and easily, taking only about 2 min.…”

Furthermore, head magnetic resonance angiography (MRA) is the most commonly used application of non-contrast MRA (NC-MRA) in clinical settings and is easily available at any institution.…”

BackgroundKawasaki disease (KD) is a systemic vasculitis; systemic arteries other than the coronary arteries should therefore also be evaluated. This study investigated the feasibility of evaluating coronary aneurysms, systemic artery aneurysms (SAAs), and cerebrovascular diseases in patients with KD using non‐contrast magnetic resonance angiography (NC‐MRA).MethodsCoronary artery protocols, including coronary magnetic resonance angiography (MRA) and vessel wall imaging, were performed in 57 examinations of 28 patients. Systemic artery protocol, including SAA scans and head MRA, along with coronary artery protocol, were performed in 42 examinations of 42 patients. The image quality of the SAAs was evaluated on a 4‐point scale. Examination time and sedation dosage were compared between the protocols. The presence of SAAs and cerebrovascular disease was also evaluated.ResultsThe image quality score of SAAs was 4 (interquartile range [IQR]: 4–4) for the aorta, 4 (IQR: 3–4) for the subclavian artery, 4 (IQR: 3–4) for the renal artery, and 3 (IQR: 3–4) for the iliac artery. No differences were found between examination time (47.0 [IQR: 43.0–61.0] min vs. 51.0 [IQR: 45.0–60.0] min, p = 0.48) and sedative dose (4.63 [IQR: 3.93–5.79] mg/kg vs. 4.21 [IQR: 3.56–5.71] mg/kg, p = 0.37) between the protocols. Systemic artery protocol detected SAAs in three patients (7.1%), and cerebrovascular disease was not detected.ConclusionsEvaluating the coronary and systemic arteries in patients with KD using NC‐MRA on a single examination was possible without compromising examination time or sedation dose. The systemic artery protocol was useful in finding SAAs.
