Using dual-energy x-ray imaging to enhance automated lung tumor tracking during real-time adaptive radiotherapy.
(WILEY, 2015-12-01)
PURPOSE: Real-time, markerless localization of lung tumors with kV imaging is often inhibited by ribs obscuring the tumor and poor soft-tissue contrast. This study investigates the use of dual-energy imaging, which can ...
Evaluation of three presets for four-dimensional cone beam CT in lung radiotherapy verification by visual grading analysis.
(BRITISH INST RADIOLOGY, 2016-07-01)
OBJECTIVE: To evaluate three image acquisition presets for four-dimensional cone beam CT (CBCT) to identify an optimal preset for lung tumour image quality while minimizing dose and acquisition time. METHODS: Nine patients ...
Spect perfusion imaging versus CT for predicting radiation injury to normal lung in lung cancer patients.
(BRITISH INST RADIOLOGY, 2019-09-01)
OBJECTIVES: In non-small cell lung cancer (NSCLC) patients, to establish whether the fractional volumes of irradiated anatomic or perfused lung differed between those with and without deteriorating lung function or radiation ...
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 ...
A randomized phase III study of 72 h infusional versus bolus bleomycin in BEP (bleomycin, etoposide and cisplatin) chemotherapy to treat IGCCCG good prognosis metastatic germ cell tumours (TE-3).
(OXFORD UNIV PRESS, 2017-06-01)
BACKGROUND: Bleomycin is an integral part of combination chemotherapy in germ cell tumours. Pulmonary toxicity often necessitates drug cessation and death occurs in 1%-2% of patients. A continuous infusion of bleomycin ...
The UK HeartSpare Study (Stage II): Multicentre Evaluation of a Voluntary Breath-hold Technique in Patients Receiving Breast Radiotherapy.
(ELSEVIER SCIENCE LONDON, 2017-03-01)
AIMS: To evaluate the feasibility and heart-sparing ability of the voluntary breath-hold (VBH) technique in a multicentre setting. MATERIALS AND METHODS: Patients were recruited from 10 UK centres. Following surgery for ...
A radiomics-based decision support tool improves lung cancer diagnosis in combination with the Herder score in large lung nodules.
(ELSEVIER, 2022-12-01)
BACKGROUND: Large lung nodules (≥15 mm) have the highest risk of malignancy, and may exhibit important differences in phenotypic or clinical characteristics to their smaller counterparts. Existing risk models do not stratify ...
Independent component analysis (ICA) applied to dynamic oxygen-enhanced MRI (OE-MRI) for robust functional lung imaging at 3 T.
(WILEY, 2024-03-01)
PURPOSE: Dynamic lung oxygen-enhanced MRI (OE-MRI) is challenging due to the presence of confounding signals and poor signal-to-noise ratio, particularly at 3 T. We have created a robust pipeline utilizing independent ...
Stability of radiomics features in apparent diffusion coefficient maps from a multi-centre test-retest trial.
(NATURE PORTFOLIO, 2019-03-18)
Quantitative radiomics features, extracted from medical images, characterize tumour-phenotypes and have been shown to provide prognostic value in predicting clinical outcomes. Stability of radiomics features extracted from ...
