1.5 tesla scanner

Manufactured by Philips

Sourced in Netherlands

The 1.5 Tesla scanner is a medical imaging device designed for magnetic resonance imaging (MRI) procedures. It generates a strong magnetic field of 1.5 Tesla, which is used to create detailed images of the body's internal structures. The core function of the 1.5 Tesla scanner is to produce high-quality MRI scans for diagnostic and clinical purposes.

Brain MRI Volumetric Analysis Protocol

An MRI scan of the brain was performed on a different visit in order to calculate WMH volumes. All MRI images were acquired using a 1·5 Tesla scanner (Philips, The Netherlands) using an 8 channel head coil. After initial survey images T1 structural images of the brain with an axial oblique orientation were acquired. All images were examined for quality.
Cortical reconstruction and volumetric segmentation was performed with the Freesurfer image analysis suite (Freesurfer version 5·1·0, Athinoula A. Martinos Center for Biomedical Imaging, Charlestown, Massachusetts), which is documented and freely available for download online (http://surfer.nmr.mgh.harvard.edu/). All Freesurfer images were examined by an independent researcher for accurate volume reconstruction and correction of errors.

Emotional Auditory Paradigm for Hallucinatory Experiences

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

A 1.5 Tesla scanner (Philips Medical Systems) was used to acquire BOLD contrasts during a stimulation paradigm (Escartí et al., 2010 (link); Sanjuán et al., 2005 (link)). An emotional auditory paradigm was designed to evoke emotions related to the patients' hallucinatory experiences (Supplementary material 1). The participants were binaurally stimulated during two different sessions. The activation blocks in one session consisted of 13 Spanish words with high emotional content. The other session had activation blocks containing 13 words with neutral or low emotional content. Four blocks of stimuli (20 s each) were interleaved with four blocks of rest of 20 s each. The subjects were informed before the test regarding the two types of words they were going to hear and were asked to focus their attention on these words.

Multimodal MRI Stroke Assessment Protocol

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

A sample of anonymised MRI brain scans performed over a consecutive 6 month period (January 2018-June 2018) at a single UK acute stroke centre was used. All cases were scanned using a 1.5 tesla scanner (Phillips, Achieva, Eindhoven, The Netherlands) and patients were all imaged for suspected stroke. Only those scanned with the SENSE NeuroVascular (NV) coil and SENSE head coil were included for parity of image quality. Equipment and imaging protocol details were identified and recorded through the picture archiving and communication system (PACS).
The routine protocol for suspected stroke imaging at the study site includes diffusion weighted imaging (DWI) and gradient-and-spin echo (GRASE) sequences.
DWI is essential for infarct detection. [28] [29] [30] GRASE is a blood-sensitive sequence for haemorrhage detection 31 and T2*GRE is for CMB detection (and confirms ICH). 21 Additionally, T1, T2 spin echo (T2SE) and fluid attenuated inversion recovery (T2 FLAIR) are acquired when other pathology mimicking stroke is suspected. [28] [29] [30] In our site a T2*GRE is performed upon request by the stroke physician on call (SPOC) or when there is suspicion of ICH on previous imaging sequences.
Cases only having had DWI, had insufficient data to be included in the analysis, so were automatically excluded.

Cardiovascular Assessment in Childhood Cancer Survivors

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

Long-term childhood cancer survivors were prospectively recruited after written informed consent. Study protocol was approved by the institutional review board. Subjects underwent a cardiovascular magnetic resonance (CMR) study on a 1.5 Tesla scanner (Philips, Best, Netherlands) with routine cine acquisition in long and short axis planes, tissue characterization with native T1 mapping and late gadolinium enhancement (LGE), selected 2D phase contrast flow imaging and 3D whole heart anatomy. Ventricular volumes, mass, and ejection fraction (EF) were obtained via standard planimetry techniques using a semiautomated commercial software (CMRtools, Imperial College, London, United Kingdom). Myocardial and left atrial (LA) strain parameters were derived from balanced SSFP cine images using dedicated software (TomTec Imaging Systems, 2D CPA MR, Cardiac Performance Analysis, Version 1.1.2.36, Unterschleissheim, Germany). LA reservoir, conduit and contractile functions were then quantified by both fractional volume changes and CMR feature tracking derived strain and strain rate. Transit times for pulse wave velocity (PWV) computations were determined using the foot-to-foot methodology.

Cardiac Function in Asymptomatic Twins

Female subjects from the Twins UK cohort with no overt cardiac disease were prospectively recruited for a CMR study on a 1.5 Tesla scanner (Philips, Best, Netherlands) with tissue characterization (T1 mapping and late gadolinium enhancement). Patients with atrial fibrillation, valvular disease, regional wall motion abnormalities at rest or areas of myocardial enhancement were excluded from the analysis. LA reservoir, conduit and contractile functions were quantified by both fractional volume changes and CMR feature tracking derived strain and strain rate. Additionally, CMR feature tracking derived myocardial deformation indices and pulse wave velocity (PWV) (foot-to-foot methodology), were calculated.

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.
