Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) is a method of investigating microvascular structure and function by tracking the pharmacokinetics of injected low-molecular weight contrast agents as they pass through the tumour vasculature. It is sensitive to changes in tumour blood perfusion and vascular permeability and has been applied for cancer detection, characterisation, staging and therapy monitoring. The technique is promising and has been proposed as a method to improve the diagnostic specificity of MRI.
The accuracy of DCE-MRI relies on the ability to model the pharmacokinetics of an injected contrast agent, using the signal intensity changes on sequential magnetic resonance images. Depending on the application, DCE-MRI measurements have included semi-quantitative analysis of the time-intensity curves such as the maximal enhancement, time to peak enhancement, enhancement gradient and signal enhancement ratio, or quantitative pharmacokinetic modelling parameters such as Ktrans.
This collection of reviews provides an overview of DCE-MRI in preclinical imaging, from image acquisition and data analysis methods to its applications and translation into clinic. Proposed topics covered in special issue:
- Image acquisition and quantification
- Arterial input function, a requisite for quantitative DCE-MRI analysis?
- Validation of DCE-MRI
- Applications for DCE-MRI: an overview
- DCE-MRI as an imaging biomarker for anti-vascular therapy
- DCE-MRI in radiation therapy applications
- Preclinical DCE-MRI and its translation into clinic

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. Papers will be published continuously (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are refereed through a peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Pharmaceutics is an international peer-reviewed Open Access quarterly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 500 CHF (Swiss Francs). English correction and/or formatting fees of 250 CHF (Swiss Francs) will be charged in certain cases for those articles accepted for publication that require extensive additional formatting and/or English corrections.
