I have recently used TopMRI for an MRI scan. I couldn’t be more impressed. I spoke with Andy, and within an hour I had been sent a referral and contacted by the radiologist at the scan provider. 45 minutes later, I was in my way to the scan appointment. Andy kept me up to date...
This work was undertaken using resources on the Dementias Platform UK (DPUK) Data Portal; the Medical Research Council supports DPUK through grant MR/L023784/2.” The study was supported in part by the French National Agency for Research (“Investissements d’Avenir” no. ANR-11-LABX-0018...
Anatomic MRI of the kidney might appear at first glance to be an easy task. However, it is challenged by the competing constraints of scan time, spatial resolution, and image quality. The selection of an appropriate MRI protocol for kidney size quantification is not so much a matter of contr...
This requires sufficient spectral separation, prior knowledge of the resonances of interest, and correct calibration of the center frequency when planning the scan; for [1-13C]pyruvate, these are relatively easily fulfilled. In this type of experiment, the resonances of pyruvate and metabolites are...
Exclusion criteria were fixed before data analysis as follows: scans with striking imaging artifacts (based on visual inspection) or with an average root mean squared relative displacement greater than 0.05 mm during the fMRI scan (as calculated by FSL) were subject to exclusion from all analyses....
Magnitude and phase images are reconstructed from the reference scan (top row) and also from the velocity-sensitive scan (bottom row). The phase images are subtracted to make the phase contrast image (velocity map) Full size image Velocity aliasing or wraparound If the velocity phase shift exce...

Additionally, we provide all measurements of scan-rescan and de-facing effects for all individual regions from all tested pipelines and all datasets, in supplemental materials. 3.2.1. T1-weighted We have previously published effects of mri_reface on SPM12, FSL (UK-Biobank pipeline), and ...
MRI studies were performed using a Bruker 7.0 T ClinScan high-field small animal MRI system with a commercial rat coil (Bruker Biospin). In vitro R2 star was performed after coincubation of IONC with/without AA at room temperature for 4 h (The molar ratio of Fe to AA approximately...
In patients with metal implants, these sequences, associated with advanced image acquisition techniques such as parallel imaging, allow to acquire MARS in a clinically feasible scan time [18]. MRI interpretation In reproductive age females, the normal ovary shows homogenous soft-tissue T1-weighted ...
