Visit Supplier
Sourced in Netherlands

The Philips 3T MRI system is a high-field magnetic resonance imaging device designed for clinical use. It generates a strong magnetic field of 3 Tesla, which enables the acquisition of detailed images of the human body's internal structures. The system's core function is to non-invasively capture and display comprehensive anatomical information to support medical diagnosis and treatment planning.

The first MRI was performed within 30 min of the treatment (day 0), while patients were still in the 3-T treatment unit (GE Discovery MR750w, Chicago, IL, USA), using the integrated body coil. The three follow-up MRIs (3 days, 1 month, and 6 months after treatment, termed days 3, 30, 180) were performed with an 8-channel head coil using a different 3-T MRI system (Philips Achieva, TX).
The patients still received dexamethasone (4 mg oral, thrice daily from day 0 until day 5) during the day 3 MRI.

Structural MRIs were acquired using a Philips 3T MRI system (Philips Healthcare; Best, The Netherlands; Version 3.2.1) equipped with a SENSE32 channel head coil. Anatomical images were obtained using sagittal 3D gradient‐echo T1‐weighted sequence (repetition time = 9.8 ms, echo time = 4.6 ms, matrix size 256 × 256, voxel size 1.17 × 1.17 × 1.2 mm, 140 slices, scan duration: 4:56 min). For each participant, high‐resolution anatomical images were examined for macroscopic abnormalities; examinations were performed by a neuroradiologist who was blinded to the clinical details of each participant. However, no such abnormalities were detected.

Comprehensive Neonatal Brain CMRO2 Assessment

Check if the same lab product or an alternative is used in the 5 most similar protocols
All MRI scans were performed on a 3T MRI system (Philips Medical Systems, Best, the Netherlands) using a body coil for transmission and an eight-channel phased-array coil for reception. No sedation was used. The neonates were well fed before MRI scan and wrapped with a vacuum immobilizer to minimize motion.
The MRI session began with a series of clinical sequences including T2 and FLAIR. A pediatric neuroradiologist read the images to confirm the absence of radiographic abnormalities.
The protocol for a complete set of CMRO2 data is shown in Figure 1b. Measurement of Yv requires two scans, a localizer PC MRI and a TRUST MRI. Measurement of CBF requires five scans, an angiogram and four quantitative PC MRI. The details of these scans are described in the following two sub-sections.

Images were acquired on a Philips 3T MRI system (Philips Healthcare, Best, The Netherlands), equipped with a SENSE-8 head coil. Scanning took place at the Leiden University Medical Center. Before scanning, all participants were introduced to the scanning situation by lying in a dummy scanner and hearing scanner sounds.

A total number of 24 in vivo 4D-flow MRI data sets are included: Cardiovascular data of healthy subjects covering the whole heart (N = 10) or thoracic aorta only (N = 11); and cerebrovascular data of patients with ICA aneurysm (N = 3). All in vivo volunteers were recruited prospectively. The institutional review board approves all imaging studies, and written consent is obtained before scanning. All cardiovascular data are acquired using a 1.5 T MRI system (Siemens Avanto) with breathing navigator gating and prospective electrocardiogram triggering. Three ICA aneurysm data sets are acquired using a 3 T MRI system (Philips Achieva TX) with prospective cardiac triggering using a peripheral pulse unit. No contrast agent is used. Acquisition parameters for both types of data are listed in Table 1. For all datasets, Maxwell terms and gradient non-linearity are corrected during reconstruction. Eddy current phase offset is corrected offline.

Figure 3 outlines the process for acquisition and processing. Images are acquired on a Philips 3T MRI system. For both the ice-water phantom and the PVP phantom, 10 scans were acquired in a single session with 96 gradient directions at a b-value of 2000 s/mm2 and with a variable number of minimally weighted volumes of b=0.1 s/mm2 interspersed throughout the scans. The acquisition parameters for all scans are as follows: b-value of 2000 s/mm2, interspersed b-value of 0.1 s/mm2, TR of 8394 ms, TE of 70 ms, SENSE acceleration of 2.5, slice thickness of 2.5 mm, and in-plane pixel dimensions of 2.5 mm. The number of these minimally weighted volumes was decreased every two scans giving a pair of scans of opposite phase encoded directions (left phase encoding and right phase encoding) with 13, 7, 4, 3, and 2 minimally weighted volumes at the beginning, end, and interspersed among the 96 directions in that chronological order.

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.
