Locating Surface Markers with MRI

To locate labeled surface markers, custom-made MRI markers (premium sanitary silicone DSSA, Fischerwerke) were attached to the respective positions on the surface of the animals’ bodies. Post mortem MRI imaging in six rats and four mice was performed at a field strength of 3 T (Magnetom Prisma, Siemens Healthineers), using the integrated 32-channel spine coil of the manufacturer and a 64-channel head coil, respectively. The data were acquired using a 3D turbo-spin echo sequence with variable flip-angle echo trains (3D TSE-VFL).
Detailed rat MRI protocol parameters for 3D TSE-VFL imaging with a turbo factor of 98 were as follows: 3,200 ms repetition time, 284 ms effective echo time, 586 ms echo train duration and 6.3 ms echo spacing using 300 Hz per px readout bandwidth for one slab with 208 slices covering the whole rat at 0.4 × 0.4 × 0.4 mm³ isotropic resolution. One average in combination with parallel imaging (here GRAPPA acceleration factor of 2) yielded an overall acquisition time of 18 min 5 s.
Mouse MRI images were collected utilizing the following parameters: 0.3 × 0.3 × 0.3 mm³ isotropic resolution, 605 ms echo train duration, 6.72 ms echo spacing, 309 Hz per px readout bandwidth and 15 min 34 s total scan time, ceteris paribus.

Detailed MRI Spinal Cord Imaging Protocol

All subjects were scanned on a Siemens 3T Skyra scanner with a 20-channel neck-head coil and a 32-channel spine coil within two weeks of their clinical examination. Axial 2D-PSIR images were acquired perpendicular to the spinal cord at the C2/C3 intervertebral disc level (Figure 1) with a total scan time of less than 2 min. Acquisition parameters: in-plane resolution = 0.78 × 0.78 mm², slice thickness = 5 mm, matrix 256 × 256, TR = 4000ms, TE = 3.22ms, TI = 400ms, angle 10°, 3 averages. To minimize neck movement during the examination, each subject was provided with an MR-compatible cervical collar^{16 (link)} and special care was taken to position the patient comfortably.
In addition, the participants underwent a standard high-resolution T1-weighted image of the brain (MPRAGE, sagittal acquisition, 1 mm³ cubic voxel, TR: 2300ms, TE: 2.98ms, TI: 900ms, angle 9°), a 3D FLAIR of the brain (sagittal acquisition, 1mm³ cubic voxel, TR: 5000ms, TE: 389ms, TI 1800ms), and standard T2-weighted sagittal images of the cervical cord (0.72 × 0.72 mm², slice thickness = 1.2 mm, FOV = 230 × 230 mm², TR: 5280ms, TE: 85ms) and thoracic cord (0.68 × 0.68 mm², slice thickness = 2 mm, FOV = 300 × 300mm², TR: 4290ms, TE: 90ms) as well as T2-weighted axial images of the cervical cord (0.62 × 0.62 mm², slice thickness = 3 mm, TR: 4000ms, TE: 92ms).

MRI and MRS acquisitions were performed on a 3-Tesla Siemens Prisma fit scanner (Siemens Medical Solutions, Erlangen, Germany) using a standard Siemens body coil for transmit and a 64-channel head-neck coil together with a 32-channel spine coil for receive. A pulse oximeter was placed on the index finger for physiological monitoring and triggering of the spine diffusion sequences.

Neck Coil Design for Improved MRI

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

The challenge of designing a close-fitting full-coverage neck coil is illustrated by the different neck shapes shown in Figure 1. To test and illustrate the concept of the NSS coils, a medium and a large coil former were shaped to fit two different neck sizes and on each former, a coil was designed, constructed and tested.
Phantom and human studies were performed to evaluate and demonstrate the value of the NSS coils. All imaging studies were performed on a Siemens MAGNETOM Prisma 3 Tesla MRI scanner, supplemented with the Siemens 20 channel head/neck and Siemens 32 channel spine coil. For the remainder of the text in this document the Siemens 20 channel head/neck coil will be referred to as either the OEM head/neck, OEM head, or OEM neck coil depending on whether the 20 channels of the head/neck, 16 channels of the head, or 4 channels of the neck are utilized. Additionally, there are 2 anterior (OEM anterior neck) and 2 posterior (OEM posterior neck) coil elements in the OEM neck coil and for the Siemens 32 channel spine (OEM spine) coil only 4 superior coil elements were used.

Cardiovascular Magnetic Resonance Imaging of Mitral Valve Pathology

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

In a subgroup of 22 patients (single centre Antwerp University Hospital), cardiovascular magnetic resonance imaging (CMR) was performed the day before the MitraClip intervention. Patients were examined using a Skyra 3 Tesla CMR scanner with a dedicated bodymatrix 18channel coil and 32-channel spine coil (Siemens, Erlangen, Germany). The entire heart was imaged in the short-axis orientation by breath-hold TrueFISP imaging. Late gadolinium enhancement of the myocardium was studied 10 minutes after intravenous bolus injection of 0.2 mmol/kg gadolinium (Dotarem®, Guerbet, The Netherlands) and imaging the whole heart in short-axis orientation using TrueFISP Phase-Sensitive Inversion Recovery sequence.
CMR analysis was performed offline using Qmass software (MEDIS, Leiden, The Netherlands) to measure ventricular volumes, mass and myocardial scar tissue. Late gadolinium enhancement was defined by signal threshold values versus reference of 6 standard deviations above the mean signal intensity (SI) of reference (remote) myocardium. 19

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.
