[CT, MRI]

Area of Science:

• Cardiology
• Pediatric Cardiology
• Diagnostic Imaging

Background:

• Coronary arterial lesions (CAL) resulting from Kawasaki disease (KD) necessitate lifelong monitoring, traditionally via conventional coronary angiography (CAG).
• Advancements in noninvasive imaging modalities, specifically multi-detector row computed tomography (MDCT) and magnetic resonance coronary angiography (MRCA), offer promising alternatives.

Purpose of the Study:

• To evaluate the utility of MRCA and MDCT in monitoring coronary arterial lesions (CAL) in patients with Kawasaki disease (KD).
• To assess the potential of these noninvasive techniques to reduce the frequency of invasive conventional coronary angiography (CAG).

Main Methods:

• Retrospective analysis of 1,200 Kawasaki disease (KD) patients who underwent magnetic resonance coronary angiography (MRCA) since 1999.
• Simultaneous MR myocardial imaging was performed in patients with severe stenotic lesions.
• Multi-detector row computed tomography (MDCT) was utilized for screening and diagnosis in adults presenting with chest pain.

Main Results:

• Magnetic resonance coronary angiography (MRCA) proved effective for monitoring coronary arterial lesions (CAL) in pediatric populations.
• Multi-detector row computed tomography (MDCT) demonstrated efficiency in screening for CAL and ruling out acute coronary syndromes in adults.
• Both noninvasive modalities showed significant potential in minimizing the need for conventional coronary angiography (CAG).

Conclusions:

• Noninvasive magnetic resonance coronary angiography (MRCA) is a valuable tool for monitoring coronary arterial lesions (CAL) in children with Kawasaki disease (KD).
• Multi-detector row computed tomography (MDCT) is an efficient method for screening coronary arterial lesions (CAL) and diagnosing acute coronary syndromes in adults.
• These advanced imaging techniques can significantly reduce the number of invasive conventional coronary angiography (CAG) procedures required.
