Multiparametric Cardiac MRI Protocol

A 12-lead electrocardiogram was conducted prior to MRI. Imaging occurred on non-dialysis days with a 1.5 T Siemens Aera scanner (Erlangen, Germany) using an 18-channel body matrix coil and 12-channel spine coil. MT-weighted CMR was completed as previously described^{12 (link)}. During separate end expiratory breath holds, cine bSSFP image pairs were obtained using excitation flip angles of 5° and 45° in a short axis stack from LV base to apex. Parameters included TE: 1.2 ms, TR: 3.2 ms, bandwidth: 930 Hz, matrix: 256 × 256, in-plane resolution: 1.02 × 1.02 mm, slice thickness: 8 mm, and GRAPPA 2.

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.
