Detecting gas-induced vasomotor changes via blood oxygenation level-dependent contrast in healthy breast parenchyma and breast carcinoma.
(WILEY-BLACKWELL, 2016-08-01)
PURPOSE: To evaluate blood oxygenation level-dependent (BOLD) contrast changes in healthy breast parenchyma and breast carcinoma during administration of vasoactive gas stimuli. MATERIALS AND METHODS: Magnetic resonance ...
Oxygen-enhanced MRI Is Feasible, Repeatable, and Detects Radiotherapy-induced Change in Hypoxia in Xenograft Models and in Patients with Non-small Cell Lung Cancer.
(AMER ASSOC CANCER RESEARCH, 2019-07-01)
PURPOSE: Hypoxia is associated with poor prognosis and is predictive of poor response to cancer treatments, including radiotherapy. Developing noninvasive biomarkers that both detect hypoxia prior to treatment and track ...
A new method for the high-precision assessment of tumor changes in response to treatment.
(OXFORD UNIV PRESS, 2018-08-01)
MOTIVATION: Imaging demonstrates that preclinical and human tumors are heterogeneous, i.e. a single tumor can exhibit multiple regions that behave differently during both development and also in response to treatment. The ...
Delayed contrast dynamics as marker of regional impairment in pulmonary fibrosis using 5D MRI - a pilot study.
(BRITISH INST RADIOLOGY, 2020-09-01)
OBJECTIVE: To analyse delayed contrast dynamics of fibrotic lesions in interstitial lung disease (ILD) using five dimensional (5D) MRI and to correlate contrast dynamics with disease severity. METHODS: 20 patients (mean ...
Inter-observer agreement of baseline whole body MRI in multiple myeloma.
(BMC, 2020-07-14)
BACKGROUND: Whole body magnetic resonance imaging (MRI) is now incorporated into international guidance for imaging patients with multiple myeloma. The aim of this study was to investigate inter-observer agreement of triple ...
The transformation of radiation oncology using real-time magnetic resonance guidance: A review.
(ELSEVIER SCI LTD, 2019-11-01)
Radiation therapy (RT) is an essential component of effective cancer care and is used across nearly all cancer types. The delivery of RT is becoming more precise through rapid advances in both computing and imaging. The ...
Standard and Hypofractionated Dose Escalation to Intraprostatic Tumor Nodules in Localized Prostate Cancer: Efficacy and Toxicity in the DELINEATE Trial.
(ELSEVIER SCIENCE INC, 2020-03-15)
PURPOSE: To report a planned analysis of the efficacy and toxicity of dose escalation to the intraprostatic dominant nodule identified on multiparametric magnetic resonance imaging using standard and hypofractionated ...
Treating locally advanced lung cancer with a 1.5T MR-Linac - Effects of the magnetic field and irradiation geometry on conventionally fractionated and isotoxic dose-escalated radiotherapy.
(ELSEVIER IRELAND LTD, 2017-11-01)
PURPOSE: This study investigates the feasibility and potential benefits of radiotherapy with a 1.5T MR-Linac for locally advanced non-small cell lung cancer (LA NSCLC) patients. MATERIAL AND METHODS: Ten patients with LA ...
Genetically modified lentiviruses that preserve microvascular function protect against late radiation damage in normal tissues.
(AMER ASSOC ADVANCEMENT SCIENCE, 2018-01-24)
Improvements in cancer survival mean that long-term toxicities, which contribute to the morbidity of cancer survivorship, are being increasingly recognized. Late adverse effects (LAEs) in normal tissues after radiotherapy ...
Magnetic Resonance Imaging-Guided Adaptive Radiation Therapy: A "Game Changer" for Prostate Treatment?
(ELSEVIER SCIENCE INC, 2018-02-01)
Radiation therapy to the prostate involves increasingly sophisticated delivery techniques and changing fractionation schedules. With a low estimated α/β ratio, a larger dose per fraction would be beneficial, with moderate ...
