Pre- and postinterventional magnetic resonance imaging (MRI) examinations were performed on a 3 Tesla scanner (Philips Healthcare, Best, The Netherlands) after administration of 0.1 mL/kg of a contrast agent containing gadolinium (Gadovist, Bayer Vital GmbH, Leverkusen, Germany).
MRI protocols included the following sequences: 3D T1 weighted sequences pre- and post-contrast administration, 3D FLAIR sequences, diffusion and susceptibility weighted sequences, and time-of-flight (ToF) sequences.
The MRI images were evaluated by at least two radiologists with at least 6 years of experience in neuroradiological diagnostics.

Quantifying Myocardial Infarction using MRI

Check if the same lab product or an alternative is used in the 5 most similar protocols

After tissue sampling, air-filled balloons were placed in the left and right ventricle. MRI analysis was performed using a 3 Tesla scanner (Philips, the Netherlands). T1-weighted images (3D FFE, TR/TE = 5.4/2.3 ms, flip angle 35°, BW = 434 Hz, 125 slices and scan duration = 02:15) with a measured isotropic resolution of 0.8 mm covering the entire heart were acquired using a quadrature head coil. Additionally, T1 measurement sequence was performed (Look Locker sequence: T1w TFE with “shared” inversion pulse, TR/TE = 2.3/4.3 ms, flip angle = 3°, inversion delay = 38.4 ms, phase interval = 65.5 ms, BW = 853 Hz, SENSE factor 2, isotropic resolution of 1 mm), and T1 maps were reconstructed using NordicIce (NordicNeuroLab, Bergen, Norway). The segmentation of the infarcted volumes was done in OsiriX [37 (link)]. T1map was used to discriminate infarcted areas with the 3D region-growing tool (threshold of 400). The used threshold lead to inclusion of pericardium and endocardium as well but as the amount is comparable and small in all groups and subjective manual processing would have been necessary, we did not subtract it from the total infarcted volume. Infarction size (ml) was determined in T1 weighted images and compared to the total left ventricular volume.

Functional MRI Acquisition Protocol for Brain Imaging

Check if the same lab product or an alternative is used in the 5 most similar protocols

The experiment was conducted on a 3 Tesla scanner (Philips Achieva), equipped with an eight-channel SENSE-head coil. Stimuli were projected on a screen behind the scanner, which participants viewed via a mirror mounted on the head-coil. T2*-weighted functional images were acquired using a gradient-echo echo-planar imaging sequence. An acquisition time of 2000 ms was used (image resolution: 3.03 × 3.03 × 4 mm³, TE = 30, flip angle = 90°). After the functional runs were completed, a high-resolution T1-weighted structural image was acquired for each participant (voxel size = 1 × 1 × 1 mm³, TE = 3.8 ms, flip angle = 8°, FoV = 288 × 232 × 175 mm³). Four dummy scans (4 ×2000 ms) were routinely acquired at the start of each functional run and were excluded from analysis.

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.
