Imaging in Vascular Interventional Radiology

Dear Colleagues,

Imaging technologies play a pivotal role in all stages of vascular and interventional radiology (VIR), including patient selection, procedural planning, real-time guidance, and post-treatment assessment. Ongoing advancements in computed tomography (CT), cone-beam CT, magnetic resonance imaging (MRI), and ultrasound, together with developments in image fusion, 3D roadmapping, and artificial intelligence, are enabling more accurate, efficient, and minimally invasive interventions.

This Special Issue of Tomography seeks to present original research, technical developments, and comprehensive reviews focused on imaging innovations in VIR. Areas of interest include intraprocedural imaging, dual-energy and photon-counting CT, MRI-guided interventions, image-based navigation, quantitative imaging biomarkers, and improvements in imaging workflows. Submissions addressing radiation dose optimization, simulation-based planning, or integration of artificial intelligence into clinical practice are also encouraged.

The objective of this issue is to highlight the transformative role of imaging in enhancing procedural precision, standardization, and clinical outcomes across a broad range of vascular and nonvascular interventional procedures.

Manuscript Submission Information

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. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Tomography is an international peer-reviewed open access monthly 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 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
