Cardiac MRI Imaging Protocol for Infarct Assessment

CMR examinations were conducted with a Philips 3-Tesla Achieva Tx whole body scanner (Philips Healthcare) equipped with a 32-element phased-array cardiac coil. The imaging protocol included an steady-state free-precession sequence to provide high-quality anatomic references, and assessment of LV mass and wall thickness; a T2W-STIR sequence to assess the extent of edema and IMH; a T2-gradient-spin-echo mapping sequence^{10 (link),16 (link)}; and a T1-weighted inversion recovery turbo field echo sequence to assess IS and MVO. CMR images were similarly analyzed using dedicated software (MR Extended Work Space 2.6, Philips Healthcare; and QMassMR 7.6, Medis) by 2 observers experienced in CMR analysis and blinded to group allocation.
Detailed information about MDCT and CMR imaging protocol and parameters, and imaging analysis, can be found in the online-only Data Supplement Methods.

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.
