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 ...
Validation of T2- and diffusion-weighted magnetic resonance imaging for mapping intra-prostatic tumour prior to focal boost dose-escalation using intensity-modulated radiotherapy (IMRT).
(ELSEVIER IRELAND LTD, 2019-12-01)
BACKGROUND AND PURPOSE: To assess the diagnostic accuracy and inter-observer agreement of T2-weighted (T2W) and diffusion-weighted (DW) magnetic resonance imaging (MRI) for mapping intra-prostatic tumour lesions (IPLs) for ...
MR guided high intensity focused ultrasound (MRgHIFU) for treating recurrent gynaecological tumours: a pilot feasibility study.
(BRITISH INST RADIOLOGY, 2019-05-16)
OBJECTIVE: To assess the feasibility of targeting recurrent gynaecological tumours with MR guided high intensity focused ultrasound (MRgHIFU). METHODS: 20 patients with recurrent gynaecological tumours were prospectively ...
Volumetry of the dominant intraprostatic tumour lesion: intersequence and interobserver differences on multiparametric MRI.
(BRITISH INST RADIOLOGY, 2017-03-01)
OBJECTIVE: To establish the interobserver reproducibility of tumour volumetry on individual multiparametric (mp) prostate MRI sequences, validate measurements with histology and determine whether functional to morphological ...
Initial experience of the BREAST-Q breast-conserving therapy module.
(SPRINGER, 2016-11-01)
PURPOSE: The most recently developed module of the BREAST-Q, a validated patient outcome measure, is for patients who have undergone breast-conserving therapy (BCT) for cancer. This aim of this study was to assess patient ...
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. ...
Monitoring Tumor Volume in Patients With Prostate Cancer Undergoing Active Surveillance: Is MRI Apparent Diffusion Coefficient Indicative of Tumor Growth?
(AMER ROENTGEN RAY SOC, 2017-09-01)
OBJECTIVE: The purpose of this study was to measure longitudinal change in tumor volume of the dominant intraprostatic lesion and determine whether baseline apparent diffusion coefficient (ADC) and change in ADC are ...
The potential role of three-dimensional surface imaging as a tool to evaluate aesthetic outcome after Breast Conserving Therapy (BCT).
(WILEY, 2017-04-01)
PURPOSE: To establish whether objective measurements of symmetry of volume and shape using three-dimensional surface imaging (3D-SI) can be used as surrogate markers of aesthetic outcome in patients who have undergone ...
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 ...
A data-driven statistical model that estimates measurement uncertainty improves interpretation of ADC reproducibility: a multi-site study of liver metastases.
(NATURE PORTFOLIO, 2017-10-26)
Apparent Diffusion Coefficient (ADC) is a potential quantitative imaging biomarker for tumour cell density and is widely used to detect early treatment changes in cancer therapy. We propose a strategy to improve confidence ...
