Free breathing contrast-enhanced time-resolved magnetic resonance angiography in congenital heart disease

چکیده
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 congenital heart disease (CHD).

Free breathing contrast-enhanced time-resolved magnetic resonance angiography in pediatric and adult congenital heart disease
BACKGROUND Contrast enhanced magnetic resonance angiography (MRA) is generally performed during a long breath-hold (BH), limiting its utility in infants and small children. This study proposes a free-breathing (FB) time resolved MRA (TRA) technique for use in pediatric and adult congenital heart disease (CHD). METHODS A TRA sequence was developed by combining spiral trajectories with sensitiv...
متن کاملSteady-state magnetic resonance angiography of the thoracic vasculature in congenital heart disease using a blood pool contrast agent: evaluation of two different techniques
Background Although contrast-enhanced first-pass MRA (FP-MRA) is frequently used to visualize the vasculature, it may not be suitable for the assessment of congenital heart disease. Blood-pool contrast agents remain within the intravascular space for several hours, allowing vessels to be imaged without relying on accurate contrast bolus timing. The purpose of this study is to compare steadystat...
متن کاملWhole-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...
متن کاملBreath-hold imaging of the coronary arteries using quiescent-interval slice-selective (qiss) magnetic resonance angiography - pilot study at 1.5 tesla and 3 tesla
BACKGROUND Coronary magnetic resonance angiography (MRA) is usually obtained with a free-breathing navigator-gated 3D acquisition. Our aim was to develop an alternative breath-hold approach that would allow the coronary arteries to be evaluated in a much shorter time and without risk of degradation by respiratory motion artifacts. For this purpose, we implemented a breath-hold, non-contrast-enh...
متن کاملA free-breathing non-contrast-enhanced pulmonary magnetic resonance angiography at 3 Tesla.
BACKGROUND The breathhold contrast-enhanced three-dimensional magnetic resonance angiography (MRA) using T1-weighted gradient-echo imaging sequence is the standard technique for MRA of the thorax. However, this technique is not desirable for certain patients with respiratory insufficiency, serious renal impairment, or allergy to contrast agents. The objective of this study was to optimize and e...
