Correlations of tumour permeability parameters with apparent diffusion coefficient in nasopharyngeal carcinoma

Physics and Imaging in Radiation Oncology, 2022
Background and Purpose: Functional imaging has an established role in therapeutic monitoring of cancer treatments. This study evaluated the correlations of tumour permeability parameters derived from dynamic contrast-enhanced magnetic resonance imaging ...

Combination therapy studies with the vascular disruptive agent combretastatin-a4-phosphate (CA4P) [PDF]

, 2009
CA4P leads to rapid vascular shutdown of tumour core, with minimal effects at the well perfused periphery. CA4P showed minimal anti-tumour activity in single agent phase I studies.

Computer-aided diagnosis of breast DCE-MRI using pharmacokinetic model and 3-D morphology analysis

, 2017
Three-dimensional (3-D) dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) consists of a large number of images in different enhancement phases which are used to identify and characterize breast lesions.

Abbreviated MRI and Ultrafast MRI of the Breast

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Detection of breast cancer in MRI requires fast, dynamic contrast enhanced (DCE) imaging covering the immediate post‐contrast phase, that is, the first 60 s after contrast injection. This ensures selective depiction of invasive cancer as well as DCIS against an otherwise dark background, that is, before background parenchymal enhancement (BPE)

DCE-MRI-Derived Parameters in Evaluating Abraxane-Induced Early Vascular Response and the Effectiveness of Its Synergistic Interaction with Cisplatin - Fig 4

, 2016
(A) Representative Kep parametric maps of female athymic nude mice bearing orthotopic MDA-MB-435 tumors on days 0 and 3 after different treatments were initiated. Decreased Kep values were observed on day 3 in both A and A-P groups.

Radiomic combination of spatial and temporal features extracted from DCE-MRI for prostate cancer detection

, 2021
Multi-parametric MRI is part of the standard prostate cancer (PCa) diagnostic protocol. Recent imaging guidelines (PI-RADS v2) downgraded the value of Dynamic Contrast-Enhanced (DCE)-MRI in the diagnosis of PCa.

Comparison of Continuous‐Time Random Walk and Fractional Order Calculus Diffusion Models for Preoperative Breast Lesion Characterization: Diagnosis, Biomarker Prediction and Molecular Subtyping

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Accurate preoperative characterization of breast lesions is important for individualized management. The conventional monoexponential (Mono) model has limited ability to capture the complex microstructure of lesions. Non‐Gaussian diffusion models, including continuous‐time random walk (CTRW) and fractional‐order calculus (FROC), may

Prediction of pathological complete response to neoadjuvant chemotherapy in patients with breast cancer using a combination of contrast‐enhanced ultrasound and dynamic contrast‐enhanced magnetic resonance imaging

Cancer Medicine, 2023
This study aimed to evaluate the value of dynamic contrast‐enhanced ultrasound (CEUS) combined with dynamic contrast‐enhanced magnetic resonance imaging (DCE‐MRI) in predicting pathological complete response (pCR) in patients with breast cancer receiving

Effects of Single and Multiple Dose Tiotropium/Olodaterol in Chronic Obstructive Pulmonary Disease on Alveolar Gas Exchange Measured by Hyperpolarized 129Xe MRI

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Long‐acting muscarinic antagonists/long‐acting beta adrenoreceptor agonists lead to lung deflation and improved microvascular perfusion in hyperinflated chronic obstructive pulmonary disease (COPD), but with an unclear time course. Purpose To investigate the effect of inhalation of tiotropium/olodaterol (TIO/OLO) on MRI measures of ...
