Loop-Mediated Isothermal Amplification Assay for Detecting Tumor Markers and Human Papillomavirus: Accuracy and Supplemental Diagnostic Value to Endovaginal MRI in Cervical Cancer.
(FRONTIERS MEDIA SA, 2021-11-01)OBJECTIVE: To establish the sensitivity and specificity of a human papillomavirus (HPV) and tumor marker DNA/mRNA assay for detecting cervical cancer that is transferrable to a Lab-on-a-chip platform and determine its ... -
Low-cost Kinect Version 2 imaging system for breath hold monitoring and gating: Proof of concept study for breast cancer VMAT radiotherapy.
(WILEY, 2018-05-01)Voluntary inspiration breath hold (VIBH) for left breast cancer patients has been shown to be a safe and effective method of reducing radiation dose to the heart. Currently, VIBH protocol compliance is monitored visually. ... -
Lung stereotactic body radiotherapy with an MR-linac - Quantifying the impact of the magnetic field and real-time tumor tracking.
(ELSEVIER IRELAND LTD, 2016-06-01)BACKGROUND AND PURPOSE: There are concerns that radiotherapy doses delivered in a magnetic field might be distorted due to the Lorentz force deflecting secondary electrons. This study investigates this effect on lung ... -
Lung volume reproducibility under ABC control and self-sustained breath-holding.
(WILEY, 2017-03-01)An Active Breathing Coordinator (ABC) can be employed to induce breath-holds during CT imaging and radiotherapy of lung, breast and liver cancer, and recently during lung cancer MRI. The apparatus measures and controls ... -
Magnetic resonance guided radiotherapy for the treatment of bladder and pancreatic cancer
(Institute of Cancer Research (University Of London), 2022-08-05)Magnetic resonance guided radiotherapy (MRgRT) has many postulated benefits over conventional radiotherapy treatment techniques. Its superior soft tissue definition, lack of imaging related ionising radiation and the ... -
Magnetic resonance imaging (MRI) guided radiotherapy for prostate cancer
(Institute of Cancer Research (University Of London), 2020-11-30)Radiotherapy to the prostate involves increasingly sophisticated delivery techniques and changing fractionation schedules. Magnetic resonance imaging (MRI) guided radiotherapy allows daily adaptive replanning and can improve ... -
Magnetic resonance imaging sequence evaluation of an MR Linac system; early clinical experience.
(Elsevier BV, 2019-12-16)OBJECTIVES: To systematically identify the preferred magnetic resonance imaging (MRI) sequences following volunteer imaging on a 1.5 Tesla (T) MR-Linear Accelerator (MR Linac) for future protocol development. METHODS: ... -
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 ... -
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, ... -
Magnetic Resonance-based Response Assessment and Dose Adaptation in Human Papilloma Virus Positive Tumors of the Oropharynx treated with Radiotherapy (MR-ADAPTOR): An R-IDEAL stage 2a-2b/Bayesian phase II trial.
(ELSEVIER IRELAND LTD, 2018-11-01)BACKGROUND: Current standard radiotherapy for oropharynx cancer (OPC) is associated with high rates of severe toxicities, shown to adversely impact patients' quality of life. Given excellent outcomes of human papilloma ... -

Magnitude of observer error using cone beam CT for prostate interfraction motion estimation: effect of reducing scan length or increasing exposure.
(BRITISH INST RADIOLOGY, 2015-10-01)OBJECTIVE: Cone beam CT (CBCT) enables soft-tissue registration to planning CT for position verification in radiotherapy. The aim of this study was to determine the interobserver error (IOE) in prostate position verification ... -
Male breast cancer in BRCA1 and BRCA2 mutation carriers: pathology data from the Consortium of Investigators of Modifiers of BRCA1/2.
(BMC, 2016-02-09)BACKGROUND: BRCA1 and, more commonly, BRCA2 mutations are associated with increased risk of male breast cancer (MBC). However, only a paucity of data exists on the pathology of breast cancers (BCs) in men with BRCA1/2 ... -
