Iterative framework for the joint segmentation and CT synthesis of MR images: application to MRI-only radiotherapy treatment planning.
(IOP PUBLISHING LTD, 2017-06-07)
To tackle the problem of magnetic resonance imaging (MRI)-only radiotherapy treatment planning (RTP), we propose a multi-atlas information propagation scheme that jointly segments organs and generates pseudo x-ray computed ...
A radiobiological model of metastatic burden reduction for molecular radiotherapy: application to patients with bone metastases.
(IOP PUBLISHING LTD, 2017-04-07)
Skeletal tumour burden is a biomarker of prognosis and survival in cancer patients. This study proposes a novel method based on the linear quadratic model to predict the reduction in metastatic tumour burden as a function ...
Diffusion-weighted (DW) MRI in lung cancers: ADC test-retest repeatability.
(SPRINGER, 2017-11-01)
PURPOSE: To determine the test-retest repeatability of Apparent Diffusion Coefficient (ADC) measurements across institutions and MRI vendors, plus investigate the effect of post-processing methodology on measurement ...
The effect of parotid gland-sparing intensity-modulated radiotherapy on salivary composition, flow rate and xerostomia measures.
(WILEY, 2017-10-01)
OBJECTIVES: To describe parotid gland (PG) saliva organic and inorganic composition and flow rate changes, after curative intensity-modulated radiotherapy (IMRT) for head and neck cancer (HNC), and analyse the relationship ...
Randomized Phase II Study Investigating Pazopanib Versus Weekly Paclitaxel in Relapsed or Progressive Urothelial Cancer.
(AMER SOC CLINICAL ONCOLOGY, 2017-06-01)
Purpose Two previous single-arm trials have drawn conflicting conclusions regarding the activity of pazopanib in urothelial cancers after failure of platinum-based chemotherapy. Patients and Methods This randomized (1:1) ...
Immunoassays for the quantification of ALK and phosphorylated ALK support the evaluation of on-target ALK inhibitors in neuroblastoma.
(WILEY, 2017-08-01)
Targeted inhibition of anaplastic lymphoma kinase (ALK) is a successful approach for the treatment of many ALK-aberrant malignancies; however, the presence of resistant mutations necessitates both the development of more ...
Evaluation of a multi-atlas CT synthesis approach for MRI-only radiotherapy treatment planning.
(ELSEVIER SCI LTD, 2017-03-01)
BACKGROUND AND PURPOSE: Computed tomography (CT) imaging is the current gold standard for radiotherapy treatment planning (RTP). The establishment of a magnetic resonance imaging (MRI) only RTP workflow requires the ...
The predictive and prognostic value of tumour necrosis in muscle invasive bladder cancer patients receiving radiotherapy with or without chemotherapy in the BC2001 trial (CRUK/01/004).
(ELSEVIER SCI LTD, 2017-02-28)
BACKGROUND: Severe chronic hypoxia is associated with tumour necrosis. In patients with muscle invasive bladder cancer (MIBC), necrosis is prognostic for survival following surgery or radiotherapy and predicts benefit from ...
A novel probabilistic approach to generating PTV with partial voxel contributions.
(IOP PUBLISHING LTD, 2017-06-21)
Radiotherapy treatment planning for use with high-energy photon beams currently employs a binary approach in defining the planning target volume (PTV). We propose a margin concept that takes the beam directions into account, ...
Optically and acoustically triggerable sub-micron phase-change contrast agents for enhanced photoacoustic and ultrasound imaging.
(ELSEVIER GMBH, 2017-06-01)
We demonstrate a versatile phase-change sub-micron contrast agent providing three modes of contrast enhancement: 1) photoacoustic imaging contrast, 2) ultrasound contrast with optical activation, and 3) ultrasound contrast ...
