MRI examinations were performed using a 1.5 T whole body imaging system (Gyroscan Intera, Philips Medical System, The Netherlands) and a breast coil. Patients were imaged in the prone position with T2-weighted and diffusion-weighted imaging (DWI) (b0, b600) sequences, and a 3D gradient echo axial T1-weighted sequence with fat suppression (SPAIR). Scan parameters were TR/TE = 4.8/2.4 ms, flip angle = 10°, FOV = 355 × 355 mm, matrix 320 × 320, slice thickness 2.5 mm, voxel size 0.65 × 0.65 × 1.25 mm after reconstruction. The anatomic study was followed by a dynamic study. Patients received 0.1 mmol/kg of gadobenate dimeglumine (Multihance, Bracco Imaging, Germany) followed by 30 mL saline flush injected at a rate of 2 mL/s with an automated injector. One pre- and five post-injection images were acquired with a temporal resolution of approximately 60 s. The total acquisition time for the protocol was about 6 min. Analyses were performed on subtracted images, i.e. the residual difference image obtained after the second post-contrast image has been subtracted from the pre-contrast image.

In order to achieve quantitative hemodynamic measurements of blood-brain barrier opening and permeability, a bolus of gadobenate dimeglumine (Multihance, Bracco Diagnostics Inc. Monroe Township, NJ 08831, USA) was injected and dynamic contrast enhancement (DCE) MR imaging was performed immediately, Day 1, and Day 7 post treatment (TR/ TE = 65/3 ms, average = 2, field of view 25 mm, flip angle 35°, matrix size=68×128, slice thickness=1.3 mm).
Post-contrast T1-weighted imaging (TR/ TE =720/11 milliseconds, 4 averages, field of view=25 mm, matrix size=248×512, slice thickness=0.6 mm) was obtained to depict the area of contrast-enhancement in the hippocampus.
T2*- weighted gradient echo imaging (repetition time/echo time [TR/TE]=391/20 ms, flip angle 20°, 3 averages, field of view 25 mm, matrix size=256×256, slice thickness 0.8 mm) was performed immediately after sonication to evaluate possible hemorrhagic complications.
To assess resulting lesions during the follow-up period, T2-weighted fast spin echo (FSE) images (TR/TE=4800/85 ms, 1 average, field of view=25 mm, matrix size=240×256, slice thickness 1.2 mm) were acquired at three time points: immediately, Day 1 and Day 7 after sonication.

All MRIs in this study were acquired using a 1.5 Tesla (Signa HDx, GE Healthcare, Little Chalfont, United Kingdom[44]; Signa HDxt, GE Healthcare[5]; MAGNETOM Avanto, Siemens, Munich, Germany[37]) or 3.0 Tesla scanner (Signa HDx, GE Healthcare[167]; MAGNETOM Trio, Siemens, Munich, Germany[25]) scanner using a breast coil (Invivo, Orlando, FL). More details were illustrated in Table 1. Each case had the following sequences: nonfat-saturated T1-weighted, fat-saturated T2-weighted sequence, and pre-contrast followed by three dynamic post-contrast T1-weighted gradient echo series with fat suppression after intravenous administration of gadopentetate dimeglumine (Magnevist, Bayer Health Care, Berlin, Germany) or gadobenate dimeglumine (MultiHance, Bracco, Milan, Italy). Contrast load was determined using a weight based dosing protocol (0.2 mL/kg). The estrogen receptor (ER), progesterone receptor (PR), and HER2-neu status were obtained from the initial breast biopsy pathology report.

MRI examinations were performed using 1.5‐T (n = 37) and 3‐T (n = 10) Philips MRI systems (Ingenia, Achieva; Philips Healthcare, Amsterdam, Netherlands). The acquired sequences included axial T1WI and fat‐suppressed T2WI, three‐dimensional (3D) contrast‐enhanced fat‐suppressed T1WI, and DWI using echo‐planar imaging. DWI was performed with b‐values of 0 and 1000 seconds/mm2 and the following parameters: repetition time (TR) range, 5000‐9000 ms; echo time (TE) range, 58‐90 ms; number of excitations, 1; slice thickness/gap, 4‐5/0‐1 mm; field of view, 240 × 240 mm; pixel size, 1.5 × 1.5 mm, and three diffusion directions. DCE‐MRI was performed using a 3D T1‐weighted (3D‐T1) fast field echo and the following parameters: TR, 4.8 ms; TE, 2 ms; flip angle, 30°; slice thickness/gap, 5/0 mm; field of view,  200 × 200 mm2; voxel size/matrix, 1.0 × 1.0 × 5.0 mm3/240 × 240; number of excitations, 1; number of slices per dynamic scan, 30; temporal resolution, 8.4 s; and total acquisition time, 4 minutes and 23 seconds.

Mice were anesthetized with isoflurane and restrained in a 3-point head holder. Images were acquired with a 4.7 T small-animal Agilent/Varian DirectDrive1 scanner using an actively decoupled volume coil (transmit) and 1.5 cm surface coil (receive). Before loading into the magnet, mice were given an intraperitoneal injection of 0.5 mL MultiHance (gadobenate dimeglumine, Bracco Diagnostics Inc, Princeton, NJ) contrast agent diluted 1:10 in sterile saline. All data were collected with a field of view of 15 × 15 mm2, 21 contiguous slices with a thickness of 0.5 mm, imaging matrix of 128 by 128 and 4 averages. Spin-echo T2-weighted (TR = 2000 ms, TE = 50 ms), spin-echo T1-weighted (TR = 650 ms, TE =20 ms), and gradient-echo proton-density (PD) weighted (TR = 500 ms, TE = 5 ms, flip angle = 20) datasets were acquired, in this order, for each mouse at each time point.

All but 4 patients (2%) included in this study underwent c-MRI with and without intravenous contrast administration. Of the 4 patients who underwent c-MRI without intravenous contrast, 1 underwent MR angiography of the neck with intravenous contrast, which allowed postcontrast assessment of the cervical spine.
MRI was performed on either a 3.0-T (TIM Trio, Siemens Healthcare) or 1.5-T (Avanto, Siemens Healthcare; or Intera, Phillips) using a head-neck array coil for cervical spine imaging. A standard dose (0.1 mmol/kg) of gadobenate dimeglumine (MultiHance, Bracco Diagnostics) was injected at 2–3 ml/sec. The standardized MRI protocol obtained included a precontrast sagittal T1-weighted (TE 10 msec, TR 400 msec, flip angle (FA) 90°, slice thickness 3 mm), sagittal T2-weighted (TE 90 msec, TR 2500 msec, FA 90°, slice thickness 3 mm), axial T2-weighted (TE 90 msec, TR 5300 msec, FA 90°, slice thickness 3 mm), and/or postcontrast sagittal T1-weighted (TE 10 msec, TR 400 msec, FA 90°, slice thickness 3 mm) and axial T1-weighted (TE 10 msec, TR 1600 msec, FA 90°, slice thickness 3 mm) images of the cervical spine.

Comprehensive Abdominal MRI Protocol

Check if the same lab product or an alternative is used in the 5 most similar protocols
The MRI examinations were performed in a 3T MRI scanner (Magnetom Skyra; Siemens) with the patient in a supine position using a multichannel phased-array body coil covering the whole abdomen and pelvis. Before the scan, a bellyband was wrapped around the patient’s abdomen to reduce the motion artefacts. The MRI protocol included conventional static MRE sequences and DCE-MRI sequences. First, static MRE was applied: Coronal and axial 2D fat-suppressed T2-weighted half-Fourier acquisition single-shot turbo spin echo, two axial T2-weighted True FISP (Trufi) sequences with and without fat saturation, DWI (b = 50/800), and unenhanced 3D fat-suppressed T1-weighted volumetric interpolated breath hold examination (3D-VIBE). After the intravenous administration of a gadolinium-based contrast medium (0.1 mL/kg bodyweight of gadobenate dimeglumine, MultiHance, Bracco Diagnostics) at an injection rate of 2 mL/s followed by a subsequent injection of the same amount of normal saline, the Twist VIBE-based DCE sequence was continuously applied followed by the coronal and axial T1-weighted Dixon sequence 3 min after administration. The detailed parameters of the MRI protocol are given in Table 1.

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.
