Comparison of three reference methods for the measurement of intracellular pH using 31P MRS in healthy volunteers and patients with lymphoma.
(WILEY-BLACKWELL, 2014-02-01)
31P magnetic resonance spectroscopy (31P MRS) can measure intracellular pH (pHi) using the chemical shift difference between pH-dependent inorganic phosphate (Pi) and a pH-independent reference peak. This study compared ...
Gene-environment dependence creates spurious gene-environment interaction.
(CELL PRESS, 2014-09-04)
Gene-environment interactions have the potential to shed light on biological processes leading to disease and to improve the accuracy of epidemiological risk models. However, relatively few such interactions have yet been ...
A computerized volumetric segmentation method applicable to multi-centre MRI data to support computer-aided breast tissue analysis, density assessment and lesion localization.
(SPRINGER HEIDELBERG, 2017-01-01)
Density assessment and lesion localization in breast MRI require accurate segmentation of breast tissues. A fast, computerized algorithm for volumetric breast segmentation, suitable for multi-centre data, has been developed, ...
Systematic evaluation of quantotypic peptides for targeted analysis of the human kinome.
(NATURE PUBLISHING GROUP, 2014-10-01)
In targeted proteomics it is critical that peptides are not only proteotypic but also accurately represent the level of the protein (quantotypic). Numerous approaches are used to identify proteotypic peptides, but quantotypic ...
Review of ultrasound image guidance in external beam radiotherapy part II: intra-fraction motion management and novel applications.
(IOP PUBLISHING LTD, 2016-04-21)
Imaging has become an essential tool in modern radiotherapy (RT), being used to plan dose delivery prior to treatment and verify target position before and during treatment. Ultrasound (US) imaging is cost-effective in ...
Determining the chemical exchange saturation transfer (CEST) behavior of citrate and spermine under in vivo conditions.
(WILEY-BLACKWELL, 2016-09-01)
PURPOSE: To estimate the exchange rates of labile (1) H in citrate and spermine, metabolites present in prostatic secretions, to predict the size of the citrate and spermine CEST effects in vivo. METHODS: CEST z-spectra ...
Distortion correction of echo-planar diffusion-weighted images of uterine cervix.
(WILEY-BLACKWELL, 2016-05-01)
PURPOSE: To investigate the clinical utility of the reverse gradient algorithm in correcting distortions in diffusion-weighted images of the cervix and for increasing diagnostic performance. MATERIALS AND METHODS: Forty-one ...
Fiducial marker based intra-fraction motion assessment on cine-MR for MR-linac treatment of prostate cancer.
(2019-04-04)
We have developed a method to determine intrafraction motion of the prostate through automatic fiducial marker (FM) tracking on 3D cine-magnetic resonance (MR) images with high spatial and temporal resolution. Twenty-nine ...
The impact of 2D cine MR imaging parameters on automated tumor and organ localization for MR-guided real-time adaptive radiotherapy.
(IOP PUBLISHING LTD, 2018-11-22)
2D cine MR imaging may be utilized to monitor rapidly moving tumors and organs-at-risk for real-time adaptive radiotherapy. This study systematically investigates the impact of geometric imaging parameters on the ability ...
Principal component analysis fosr fast and model-free denoising of multi b-value diffusion-weighted MR images.
(IOP PUBLISHING LTD, 2019-04-09)
Despite the utility of tumour characterisation using quantitative parameter maps from multi-b-value diffusion-weighted MRI (DWI), clinicians often prefer the use of the image with highest diffusion-weighting (b-value), for ...
