Whole-body diffusion-weighted MR imaging for assessment of treatment response in myeloma.
(RADIOLOGICAL SOC NORTH AMERICA, 2014-06-01)
PURPOSE: To determine the feasibility of whole-body diffusion-weighted (DW) magnetic resonance (MR) imaging for assessment of treatment response in myeloma. MATERIALS AND METHODS: This prospective single-institution study ...
Assessment of treatment response by total tumor volume and global apparent diffusion coefficient using diffusion-weighted MRI in patients with metastatic bone disease: a feasibility study.
(PUBLIC LIBRARY SCIENCE, 2014-04-07)
We describe our semi-automatic segmentation of whole-body diffusion-weighted MRI (WBDWI) using a Markov random field (MRF) model to derive tumor total diffusion volume (tDV) and associated global apparent diffusion coefficient ...
Inter- and Intra-Observer Repeatability of Quantitative Whole-Body, Diffusion-Weighted Imaging (WBDWI) in Metastatic Bone Disease.
(PUBLIC LIBRARY SCIENCE, 2016-04-28)
Quantitative whole-body diffusion-weighted MRI (WB-DWI) is now possible using semi-automatic segmentation techniques. The method enables whole-body estimates of global Apparent Diffusion Coefficient (gADC) and total Diffusion ...
Repeatability of derived parameters from histograms following non-Gaussian diffusion modelling of diffusion-weighted imaging in a paediatric oncological cohort.
(SPRINGER, 2017-01-01)
OBJECTIVES: To examine repeatability of parameters derived from non-Gaussian diffusion models in data acquired in children with solid tumours. METHODS: Paediatric patients (<16 years, n = 17) were scanned twice, 24 h apart, ...
Separation of type and grade in cervical tumours using non-mono-exponential models of diffusion-weighted MRI.
(SPRINGER, 2017-02-01)
OBJECTIVES: Assessment of empirical diffusion-weighted MRI (DW-MRI) models in cervical tumours to investigate whether fitted parameters distinguish between types and grades of tumours. METHODS: Forty-two patients (24 ...
Nine-year Follow-up for a Study of Diffusion-weighted Magnetic Resonance Imaging in a Prospective Prostate Cancer Active Surveillance Cohort.
(ELSEVIER SCIENCE BV, 2016-06-01)
BACKGROUND: In active surveillance (AS) for prostate cancer there are few data on long-term outcomes associated with novel imaging markers. OBJECTIVE: To determine long-term outcomes with respect to the apparent diffusion ...
Distortion correction of echo-planar diffusion-weighted images of uterine cervix.
(WILEY-BLACKWELL, 2016-05-01)
PURPOSE: To investigate the clinical utility of the reverse gradient algorithm in correcting distortions in diffusion-weighted images of the cervix and for increasing diagnostic performance. MATERIALS AND METHODS: Forty-one ...
Variation of the apparent diffusion coefficient of skull bone marrow by age group, pubertal status, and gender in a pediatric population.
(SAGE PUBLICATIONS LTD, 2020-09-01)
BACKGROUND: Bone marrow composition varies with stage of development. PURPOSE: To assess differences in apparent diffusion coefficient (ADC) derived from clivus bone marrow in healthy children by age, pubertal status, and ...
What's New for Clinical Whole-body MRI (WB-MRI) in the 21st Century.
(BRITISH INST RADIOLOGY, 2020-11-01)
Whole-body MRI (WB-MRI) has evolved since its first introduction in the 1970s as an imaging technique to detect and survey disease across multiple sites and organ systems in the body. The development of diffusion-weighted ...
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 ...
