Whole-heart contrast enhanced coronary magnetic resonance angiography using respiratory image based navigation in patients with congenital heart disease
Background Despite ongoing advances in magnetic resonance (MR) sequence development, coronary imaging in paediatric patients remains challenging. MR imaging of the coronary arteries can be difficult due to high heart rates (HR), small diameter of the coronary arteries, and poor contrast between the blood pool and extravascular structures. The use of higher relaxivity contrast agents has been sh...

This study had institutional review board approval, and all patients gave informed consent. The purpose of this study was to prospectively evaluate the use of whole-heart three-dimensional (3D) coronary magnetic resonance (MR) angiography in patients suspected of having coronary artery disease. Whole-heart coronary MR angiography was performed in 39 patients (30 men and nine women; mean age, 63...
متن کاملFree breathing contrast-enhanced time-resolved magnetic resonance angiography in congenital heart disease
Background Contrast enhanced magnetic resonance angiography (MRA) is generally performed during a long breath-hold (BH), limiting its use in infants and children. Time resolved MR angiography (TRA) often use data sharing techniques, making it is necessary to acquire data during a BH. This study proposes a high-resolution free breathing (FB) TRA sequence for use in adults and children with conge...

Abstract Background: The thyroid hormones influence on all metabolic pathways. After heart surgery using cardiopulmonary bypass (CPB), serum T3 decreases and remains low for at least 24 hours. Several studies on pediatric have reported reduction of thyroid hormones after heart surgery. This study aimed to investigate the status of thyroid function tests in children with CPB surgery. Metho...
