Special Issue Information

Dear Colleagues,

Advances in veterinary imaging are improving veterinary care for pets such as dogs, cats, and exotic animals, and advanced ultrasound techniques, including contrast-enhanced ultrasound (CEUS), deliver dynamic real-time assessment of tissue perfusion, and imaging-guided biopsies ensure precise, targeted sampling with reduced patient risk. High-resolution computed tomography (CT) and magnetic resonance imaging (MRI) provide unparalleled anatomical and functional detail, while interventional radiology translates these insights into minimally invasive, image-guided diagnosis and therapies.

The integration of imaging with emerging technologies, such as three-dimensional (3D) printing and augmented reality (AR), is redefining how surgeons plan, execute, and evaluate procedures. Patient-specific imaging datasets can be transformed into accurate 3D-printed models for preoperative rehearsal, surgical training, and custom device or implant design, while AR enables real-time overlay of data within the surgical field, improving spatial orientation and decision-making.

These advances are driving a new era where diagnosis, planning, and intervention form a seamless continuum, enhancing precision, reducing invasiveness, and expanding therapeutic possibilities.

This Special Issue presents the latest research, clinical applications, and translational innovations at the intersection of imaging and surgery—highlighting how technology is reshaping veterinary practice and setting new benchmarks for patient care.

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-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Veterinary Sciences 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 2100 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.

The aim of this retrospective study was to compare lesion conspicuity—the visibility of a lesion relative to surrounding tissue—and CT characteristics of pancreatic insulinomas in dogs using multiphase dual-energy CT (DECT) and dynamic 4D perfusion CT. Seventy dogs with insulinomas, confirmed either cytologically or histologically, or with clinical and imaging findings consistent with the diagnosis, were included. Forty dogs underwent perfusion CT and 30 underwent multiphase DECT on a dual-source, dual-energy CT scanner (192 × 2 detector configuration). Imaging evaluations focused on arterial and portal phases for DECT, and early arterial, late arterial, pancreatic, and portal venous phases for perfusion CT. Tumor conspicuity was quantified using the tumor-to-pancreas ratio (TPR) and contrast-to-noise ratio (CNR), while time-to-peak (TTP) enhancement was recorded for both tumors and pancreatic parenchyma. Perfusion CT demonstrated significantly higher TPR and CNR values compared to DECT (p < 0.001), indicating improved tumor visibility. The late arterial phase of perfusion CT, although not statistically significant, showed the highest median TPR and CNR. Mean TTP for tumors was 38.8 s, slightly earlier than the pancreatic parenchyma (41.25 s). In conclusion, perfusion CT appears to enhance visualization of insulinomas in dogs, particularly between 34 and 44 s after contrast injection, aligning with the late arterial phase of perfusion CT.
