T2-Weighted 4D Magnetic Resonance Imaging for Application in Magnetic Resonance-Guided Radiotherapy Treatment Planning.
(LIPPINCOTT WILLIAMS & WILKINS, 2017-10-01)
OBJECTIVES: The aim of this study was to develop and verify a method to obtain good temporal resolution T2-weighted 4-dimensional (4D-T2w) magnetic resonance imaging (MRI) by using motion information from T1-weighted 4D ...
Imaging biomarker roadmap for cancer studies.
(NATURE PORTFOLIO, 2017-03-01)
Imaging biomarkers (IBs) are integral to the routine management of patients with cancer. IBs used daily in oncology include clinical TNM stage, objective response and left ventricular ejection fraction. Other CT, MRI, PET ...
Time-resolved angiography with stochastic trajectories for dynamic contrast-enhanced MRI in head and neck cancer: Are pharmacokinetic parameters affected?
(WILEY, 2016-11-01)
PURPOSE: To investigate the effects of different time-resolved angiography with stochastic trajectories (TWIST) k-space undersampling schemes on calculated pharmacokinetic dynamic contrast-enhanced (DCE) vascular parameters. ...
Diffusion-weighted Imaging as a Treatment Response Biomarker for Evaluating Bone Metastases in Prostate Cancer: A Pilot Study.
(RADIOLOGICAL SOC NORTH AMERICA, 2017-04-01)
Purpose To determine the usefulness of whole-body diffusion-weighted imaging (DWI) to assess the response of bone metastases to treatment in patients with metastatic castration-resistant prostate cancer (mCRPC). Materials ...
A generalized framework unifying image registration and respiratory motion models and incorporating image reconstruction, for partial image data or full images.
(IOP PUBLISHING LTD, 2017-06-07)
Surrogate-driven respiratory motion models relate the motion of the internal anatomy to easily acquired respiratory surrogate signals, such as the motion of the skin surface. They are usually built by first using image ...
Magnetic Resonance Spectroscopy to Study Glycolytic Metabolism During Autophagy.
(ELSEVIER ACADEMIC PRESS INC, 2017-01-01)
Cancer cells undergoing starvation- and treatment-induced autophagy were found to exhibit reduced intracellular lactate, reduced rates of steady-state lactate excretion and reduced real-time pyruvate-lactate exchange rates, ...
Noninvasive Imaging of Cycling Hypoxia in Head and Neck Cancer Using Intrinsic Susceptibility MRI.
(AMER ASSOC CANCER RESEARCH, 2017-08-01)
Purpose: To evaluate intrinsic susceptibility (IS) MRI for the identification of cycling hypoxia, and the assessment of its extent and spatial distribution, in head and neck squamous cell carcinoma (HNSCC) xenografts and ...
The BRAF Inhibitor Vemurafenib Activates Mitochondrial Metabolism and Inhibits Hyperpolarized Pyruvate-Lactate Exchange in BRAF-Mutant Human Melanoma Cells.
(AMER ASSOC CANCER RESEARCH, 2016-12-01)
Understanding the impact of BRAF signaling inhibition in human melanoma on key disease mechanisms is important for developing biomarkers of therapeutic response and combination strategies to improve long-term disease ...
T2-adjusted computed diffusion-weighted imaging: A novel method to enhance tumour visualisation.
(PERGAMON-ELSEVIER SCIENCE LTD, 2016-12-01)
PURPOSE: To introduce T2-adjusted computed DWI (T2-cDWI), a method that provides synthetic images at arbitrary b-values and echo times (TEs) that improve tissue contrast by removing or increasing T2 contrast in diffusion-weighted ...
Pre-natal exposures and breast tissue composition: findings from a British pre-birth cohort of young women and a systematic review.
(BMC, 2016-10-12)
BACKGROUND: Breast density, the amount of fibroglandular tissue in the adult breast for a women's age and body mass index, is a strong biomarker of susceptibility to breast cancer, which may, like breast cancer risk itself, ...
