MRI-guided prostate adaptive radiotherapy - A systematic review.
(2016-06)
Dose escalated radiotherapy improves outcomes for men with prostate cancer. A plateau for benefit from dose escalation using EBRT may not have been reached for some patients with higher risk disease. The use of increasingly ...
A comparison of the diagnostic value of MRI and 18 F-FDG-PET/CT in suspected spondylodiscitis.
(2017-02)
Purpose The purpose of this study was to evaluate the diagnostic value of 18 F-fluorodeoxyglucose (FDG) positron emission tomography and computed tomography (PET/CT scan) and magnetic resonance imaging (MRI) in diagnosing ...
Quantitative Brain MRI in Congenital Adrenal Hyperplasia: In Vivo Assessment of the Cognitive and Structural Impact of Steroid Hormones.
(2018-04)
Context:Brain white matter hyperintensities are seen on routine clinical imaging in 46% of adults with congenital adrenal hyperplasia (CAH). The extent and functional relevance of these abnormalities have not been studied ...
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 ...
Three-dimensional dose verification of adaptive radiotherapy at an MR-linac
(Institute of Cancer Research (University Of London), 2020-04-30)
The vision of accurate real-time image-guided radiotherapy (RT) has led to the development of MR-Linacs consisting of MRI scanners integrated within RT treatment units. The safe clinical operation of these devices requires ...
Calculation of absorbed dose in radiotherapy by solution of the linear Boltzmann transport equations.
(2019-01-10)
Over the last decade, dose calculations which solve the linear Boltzmann transport equations have been introduced into clinical practice and are now in widespread use. However, knowledge in the radiotherapy community ...
The diagnostic value of 18F-FDG-PET/CT and MRI in suspected vertebral osteomyelitis - a prospective study.
(2018-05)
PURPOSE:The aim of this study was to determine the diagnostic value of 18F-fluorodeoxyglucose (FDG) positron emission tomography and computed tomography (PET/CT) and magnetic resonance imaging (MRI) in diagnosing vertebral ...
Preoperative imaging in patients undergoing trachelectomy for cervical cancer: validation of a combined T2- and diffusion-weighted endovaginal MRI technique at 3.0 T.
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2014-05-01)
AIM: The aim of this study is to validate high-resolution endovaginal T2- and diffusion-weighted MRI measurements (tumour size, volume and length of uninvolved cervical canal) against histology in patients undergoing ...
Novel concepts for automated segmentation to facilitate MRI-guided radiotherapy in head and neck cancer
(Institute of Cancer Research (University Of London), 2019-09-30)
The dramatic increase of magnetic resonance imaging (MRI) in daily treatment planning and response assessment of radiotherapy (RT) requires the development of reliable auto-segmentation algorithms for organs-at-risk (OARs) ...
A computerized volumetric segmentation method applicable to multi-centre MRI data to support computer-aided breast tissue analysis, density assessment and lesion localization.
(SPRINGER HEIDELBERG, 2017-01-01)
Density assessment and lesion localization in breast MRI require accurate segmentation of breast tissues. A fast, computerized algorithm for volumetric breast segmentation, suitable for multi-centre data, has been developed, ...
