Bowel Motility Imaging with 3T MRI

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

With the subjects placed in supine position, scans were acquired with a 3T Philips Ingenia MRI scanner (Philips, Best, The Netherlands) using a combination of a posterior coil located in the table and an anterior torso‐coil covering the entire abdominal region. After initial survey sequences, a continuously tagged coronal 3D balanced fast field echo (bFFE) motility sequence of the bowel was acquired, covering a fraction of the total abdominal volume. The positioning of the scan was aimed at capturing as much small bowel as possible.
The spatiotemporal resolution of this sequence was optimized to capture the complex motion occurring in the abdominal region during free breathing, that is, temporal sampling sufficient to reach a spectral resolution capable of resolving the three sources of motion in the abdomen: respiratory motion (~16‐25 per minute), cardiac motion (~60‐100 per minute), and gastrointestinal motility (~3 to 12 per minute). The motility scan was acquired during 3.1 minutes of free breathing. The scan parameters were as follows: TE/TR: 1.25/2.5 ms, flip angle: 10°, FOV: 400x400x15 mm (FHxLRxAP), and spatial resolution: 2.5 × 2.5 × 2.5 mm (six slices), resulting in a dynamic scan time of 0.374 seconds. The tagging prepulse was set at a tag spacing of 9 mm and a delay of 50 ms, resulting in a temporal resolution of 2.7 frames per second.

Prior to treatment patients received a planning CT scan and MRI exam, including a T2-weighted scan and a diffusion weighted imaging (DWI) scan. In the NKI also a T2 mapping sequence was performed. In both institutions patients were scanned on a 3T Philips Ingenia MRI scanner. Specifications of the scanned MRI sequences are listed in Table 1. To track changes in the prostate and tumor during treatment, a weekly repeat MRI exam was scanned at each treatment fraction that included the same image sequences as the pretreatment MRI exam.

We used a 1.5 Tesla Philips Ingenia MRI scanner (Philips Medical Systems, Best, the Netherlands) and acquired axial T1 turbo spin echo sequences (repetition time (TR) 412 ms, echo time (TE) 4.0 ms, 30 slices with 8 mm slice thickness and 1 mm interslice gap, field of view (FOV) 300 × 455 mm², voxel size = 1.4 × 1.4 mm²) and coronal STIR images (repetition time (TR) 16 103 ms, echo time (TE) 70 ms, 45 slices with 6 mm slice thickness and 1 mm interslice gap, field of view (FOV) 371 × 550 × 314 mm³, voxel size = 1.6 × 2.0 mm²) of the whole body, and 6‐point Dixon fast imaging in 3D of the thighs (TR/TE1/delta TE = 9.2/1.36/1.3 ms, flip angle (FA) 12°, 125 slices, slice thickness 2 mm, FOV 450 × 394 × 252 mm³, matrix 320 × 280 × 125, voxel size 1.2 × 1.2 × 2 mm³). These Dixon parameters were used because they are the standard mDixon_QUANT protocol of our Philips MRI scanner and they produce a good signal to noise ratio with a fast acquisition time at 1.5 T. However, given that a FA of 12° and a short TR incur T1‐weighting in the Dixon images, we corrected for this in post‐processing with the formulas described in Liu et al.²⁰ We acquired three Dixon imaging stacks from the iliac crest to the tibial plateau, each overlapping by 10 slices (20 mm).

All subjects were scanned on a 3 T Philips Ingenia MRI scanner. Image acquisition protocol was performed as described previously (Weissberg et al., 2014 (link); Serlin et al., 2019 (link)). Briefly, T₁- and T₂-weighted imaging, FLAIR, diffusion, and susceptibility-weighted imaging (SWI) data were acquired, followed by a DCE sequence. After five dynamic scans, the contrast agent gadoterate meglumine (Gd-DOTA, Dotarem^®, 0.1 mmol/kg, 0.5 M, 1.5 ml/s) was administered intravenously.

We acquired MRI data at Cincinnati Children’s Hospital using a 3T Philips Ingenia MRI scanner (Best, the Netherlands) with a 32-channel head coil, as previously described (Chandwani et al., 2021 (link)). Subjects were imaged in natural sleep without sedation, between 39- and 44- weeks postmenstrual age (PMA). Before MRI scanning, each infant was fed and swaddled to promote natural sleep, as well as fitted with silicone earplugs for noise protection.
The dMRI protocol consisted of a 68-direction acquisition (phase encoding posterior to anterior) obtained in the axial plane with full brain coverage: 61 directions with b-values of 2000 s/mm² and 7 with b-values of 0 s/mm² (the b0s were distributed uniformly for intra-scan motion correction). In a separate acquisition, 6 more b0s were obtained (phase encoding anterior to posterior). Scan parameters used in both acquisitions: echo time (TE) 88 ms, repetition time (TR) 5073 ms, flip angle = 90°, FOV 160x160 mm², 80 × 78 matrix size, 2 mm slices; multiband factor = 2; SENSE factor = 2, and scan time 6:27 min. The following acquisition parameters were used for the axial T2-weighted image: TE 166 ms, TR 18567 ms, flip angle = 90°, voxel dimensions 1.0x1.0x1.0 mm³, and scan time 3:43 min.

All animal experiments were conducted in accordance with the guidelines of the Institutional Animal Care and Use Committee (IACUC). The female nude mouse tumor model was constructed by the subcutaneous injection of SKOV-3 cells (2 × 10⁶ cells/mouse). When the tumor volumes reached 50–100 mm³, HMON@CuS/Gd₂O₃ NP solution was intravenously injected into the tumor-bearing mice. In vivo fluorescence imaging of tumor-bearing mice was conducted using a white-light and near-infrared dual-channel image-guided device (DIGITAL PRECISION MEDICINE Company, Beijing, China) at 6, 12, and 24 h after injection. For ex vivo fluorescence imaging, the tumor-bearing mice were sacrificed at 24 h, and the excised heart, liver, spleen, lung, kidney, brain, and tumor tissues were evaluated.
For in vivo MR imaging, SKOV-3 tumor-bearing mice were intravenously injected with HMON@CuS/Gd₂O₃ NP solution. T1-weighted MR images of the tumor area before and 24 h postinjection were collected using a 3.0 T Philips Ingenia MRI scanner with a special animal coil.
To perform in vivo IRT imaging, SKOV-3 tumor-bearing mice were also injected with HMON@CuS/Gd₂O₃ NP solution. Subsequently, the mice were irradiated with 808 nm irradiation at .5 W/cm² for 8 min before and 24 h post-injection. The minimal tumor temperature changes during laser irradiation were monitored using an IR thermographic camera.

The MRI protocol followed a strict and standardized protocol, as previously described (Ringstad et al., 2017 (link); Ringstad et al., 2018 ). Sagittal 3D T1-weighted gradient echo volume scans were obtained using a 3 T Philips Ingenia MRI scanner (Philips Medical systems, Best, The Netherlands) with equal imaging protocol settings before and at several time points up to 48 h after intrathecal injection of gadobutrol (0.5 mmol). We categorized the MRI exams into the following time intervals based on time interval before/after intrathecal injection. Before intrathecal contrast (Pre), and 40–60 min, 2–4 h, 6–9 h, 24 h and 48 h after intrathecal injection, respectively.

The MRI protocol utilized a 3 Tesla Philips Ingenia MRI scanner (Philips Medical systems, Best, The Netherlands), with equal imaging protocol settings at each time point to acquire sagittal 3 D T1-weighted volume scans. These imaging parameters were used: Repetition time = ‘shortest’ (typically 5.1 ms), echo time = ‘shortest’ (typically 2.3 ms), Flip angle = 8 degrees, field of view = 256 x 256 cm and matrix = 256 x 256 pixels (reconstructed 512 x 512). Hundred and eighty-four over-contiguous (overlapping) slices with one mm thickness were automatically reconstructed to 368 slices with 0.5 mm thickness. The duration of each image acquisition was 6 min and 29 s. Slice orientation of image stacks was defined using an automated anatomy recognition protocol based on landmark detection in MRI data (SmartExam™, Philips Medical Systems, Best, The Netherlands) for each time point to secure consistency and reproducibility of the MRI slice placement and orientation.

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.
