Characterization of the diffusion coefficient of blood.
(WILEY, 2018-05-01)
PURPOSE: To characterize the diffusion coefficient of human blood for accurate results in intravoxel incoherent motion imaging. METHODS: Diffusion-weighted MRI of blood samples from 10 healthy volunteers was acquired with ...
Subversion of NK-cell and TNFα Immune Surveillance Drives Tumor Recurrence.
(AMER ASSOC CANCER RESEARCH, 2017-11-01)
Understanding how incompletely cleared primary tumors transition from minimal residual disease (MRD) into treatment-resistant, immune-invisible recurrences has major clinical significance. We show here that this transition ...
Combined MYC and P53 defects emerge at medulloblastoma relapse and define rapidly progressive, therapeutically targetable disease.
(CELL PRESS, 2015-01-12)
We undertook a comprehensive clinical and biological investigation of serial medulloblastoma biopsies obtained at diagnosis and relapse. Combined MYC family amplifications and P53 pathway defects commonly emerged at relapse, ...
Diffusion-weighted MRI for imaging cell death after cytotoxic or apoptosis-inducing therapy.
(NATURE PUBLISHING GROUP, 2015-04-28)
BACKGROUND: Non-invasive serial imaging is desirable to detect processes such as necrotic and apoptotic cell death in cancer patients undergoing treatment. This study investigated the use of diffusion-weighted (DW-) magnetic ...
Refined histopathological predictors of BRCA1 and BRCA2 mutation status: a large-scale analysis of breast cancer characteristics from the BCAC, CIMBA, and ENIGMA consortia.
(BMC, 2014-12-23)
INTRODUCTION: The distribution of histopathological features of invasive breast tumors in BRCA1 or BRCA2 germline mutation carriers differs from that of individuals with no known mutation. Histopathological features thus ...
Repeatability and sensitivity of T2* measurements in patients with head and neck squamous cell carcinoma at 3T.
(WILEY-BLACKWELL, 2016-07-01)
PURPOSE: To determine whether quantitation of T2* is sufficiently repeatable and sensitive to detect clinically relevant oxygenation levels in head and neck squamous cell carcinoma (HNSCC) at 3T. MATERIALS AND METHODS: Ten ...
Wide versus narrow excision margins for high-risk, primary cutaneous melanomas: long-term follow-up of survival in a randomised trial.
(ELSEVIER SCIENCE INC, 2016-02-01)
BACKGROUND: The necessary margin of excision for cutaneous melanomas greater than 2 mm in thickness is controversial. At a median follow-up of 5 years, findings from our previously published randomised trial of narrow (1 ...
Comparison of optimised endovaginal vs external array coil T2-weighted and diffusion-weighted imaging techniques for detecting suspected early stage (IA/IB1) uterine cervical cancer.
(SPRINGER, 2016-04-01)
OBJECTIVE: To compare sensitivity and specificity of endovaginal versus external-array coil T2-W and T2-W + DWI for detecting and staging small cervical tumours. METHODS: Optimised endovaginal and external array coil MRI ...
Evaluation of diffusion models in breast cancer.
(WILEY, 2015-08-01)
PURPOSE: The purpose of this study is to investigate whether the microvascular pseudodiffusion effects resulting with non-monoexponential behavior are present in breast cancer, taking into account tumor spatial heterogeneity. ...
Classification of fibroglandular tissue distribution in the breast based on radiotherapy planning CT.
(BIOMED CENTRAL LTD, 2016-01-14)
BACKGROUND: Accurate segmentation of breast tissues is required for a number of applications such as model based deformable registration in breast radiotherapy. The accuracy of breast tissue segmentation is affected by the ...
