Steady-state magnetic resonance angiography of the thoracic vasculature in congenital heart disease using a blood pool contrast agent: evaluation of two different techniques
نویسندگان
چکیده
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 steadystate magnetic resonance angiography (SS-MRA) following injection of a blood-pool contras agent to first-pass MR angiography (FP-MRA) in adults with congenital heart disease.

Steady state imaging of the thoracic vasculature using inversion recovery FLASH and SSFP with a blood pool contrast agent
Background Although contrast-enhanced first-pass MRA (FP-MRA) is frequently used to visualize the thoracic vasculature, it may not be ideal for the assessment of the aortic root due to poor image quality and motion artifact. Bloodpool contrast agents remain within the intravascular space for several hours, allowing vessels to be imaged longer and therefore improving spatial resolution. The purp...
متن کاملNon-contrast-enhanced MR angiography of the thoracic aorta using a whole-chest 3D steady-state with free-precession technique
Magnetic resonance angiography (MRA) is a valuable method of evaluating the thoracic aorta in a variety of clinical situations, including assessing patients with aneurysms, pseudoaneurysms, intramural hematomas, penetrating ulcerative plaques, dissections, stenoses, or congenital anomalies. Various MR techniques have been validated to assess the size and morphology of the aorta. 2 Current MRA p...
متن کاملAnalytical determination of the chemical exchange saturation transfer (CEST) contrast in molecular magnetic resonance imaging
Magnetic resonance based on molecular imaging allows tracing contrast agents thereby facilitating early diagnosis of diseases in a non-invasive fashion that enhances the soft tissue with high spatial resolution. Recently, the exchange of protons between the contrast agent and water, known as the chemical exchange saturation transfer (CEST) effect, has been measured by applying a suitable pulse ...
