CMR examinations were conducted with a Philips 1.5-Tesla Achieva whole-body scanner (Philips Healthcare) equipped with a 16-element phased-array cardiac coil. At all time points, the imaging protocol included a standard segmented cine steady-state free-precession sequence to provide high-quality anatomic references; a T2-weighted short-tau triple inversion-recovery (T2W-STIR) sequence to assess the extent of edema and intramyocardial hemorrhage (IMH); and a T2-gradient-spin-echo mapping sequence to provide precise myocardial T2 relaxation time properties.16 (link) On day 7 and day 40 CMR, LGE imaging was performed to assess infarct size and microvascular obstruction (MVO), using a T1-weighted inversion recovery turbo field echo sequence acquired 10 to 15 minutes after intravenous administration of 0.20 mmol gadobutrol contrast agent per kg body weight.
16 element phased array cardiac coil
Manufactured by Philips
The 16-element phased-array cardiac coil is a specialized piece of lab equipment designed for magnetic resonance imaging (MRI) applications. It features 16 individual radio frequency (RF) coil elements that work together to acquire high-quality cardiac images. The core function of this coil is to enhance the signal-to-noise ratio and improve the spatial resolution of MRI scans focused on the heart region.

Cardiac magnetic resonance (CMR) examinations were conducted with a Philips 1.5-Testa Achieva whole-body scanner (Philips Healthcare) equipped with a 16-element phased-array cardiac coil and fully installed and managed by the Cardiology Department at the University Hospital of Salamanca (Barreiro-Perez et al. 2018 (link)). The imaging protocol always included a standard segmented cine steady-state free-precession (SSFP) sequence to provide high-quality anatomical references. The imaging parameters for the SSFP sequence were: 280 × 280 mm field of view, 8 mm slice thickness with no gap, 3 ms repetition time, 1.50 ms echo time, 60° flip angle, 30 cardiac phases, 1.7 × 1.7 mm voxel size and a single excitation. CMR images were analyzed using dedicated software (MR Extended Work Space 2.6, Philips Healthcare, Netherlands) by two observers experienced in CMR analysis and blinded concerning time-point allocation and patient identification.
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.
