Contrast-Enhanced Cardiac MRI Protocol

CMR imaging was performed using a 1.5T scanner (Philips Achieva, Best, The Netherlands) with a 32-element cardiac phased-array receiver coil. Scar imaging was performed using a dark-blood LGE sequence with an optimized joint inversion preparation and T₂ magnetization preparation to simultaneously suppress myocardial and blood signal and enhance blood-scar contrast^{46 (link),47}. Imaging was performed 15–25 minutes after injection of 0.15–0.2 mmol/kg gadobenate dimeglumine (MultiHance; Bracco Imaging, Milan, Italy). A respiratory navigator with an adaptive acquisition window^{48 (link)} was used for prospective motion correction. Imaging was performed in short-axis with the following parameters: gradient echo imaging sequence; spatial resolution = 1.3 × 1.3 × 1.3 mm³; field-of-view = 320 × 335 × 90 mm³; TR/TE/flip angle = 2.6/1.3msec/55°; sensitivity encoding rate = 2; centric phase-encoding order.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
