Special Issue Information

Dear Colleagues,

Following several requests from prospective authors, the deadline of this Special Issue, “Translational Preclinical Imaging: Techniques, Applications and Perspectives”, launched by MDPI’s Journal of Imaging, has been extended to 31 March 2026.

The Guest Editors of this Special Issue, Sara Gargiulo from the Institute of Clinical Physiology and Sandra Albanese from the Institute of Biostructures and Bioimaging, the National Council of Research (Italy), would like to invite potential authors to submit their contributions.

This Special Issue aims to compile original research papers and/or systematic and narrative reviews that provide updates on current applications and translational issues in preclinical imaging research.

 It seeks to bring together a diverse and complementary set of articles highlighting the contribution of preclinical imaging in multidisciplinary translational research. The topics covered will include methodological improvement or innovation in animal studies using single- or multi-modality imaging.

Do not miss the opportunity to contribute to this Special Issue!

Preclinical imaging in animal models of human disease is progressing rapidly due to advances in instrumentation and technology capabilities and a better understanding of comparative medicine and the complex interplay between animal welfare and the quality of science. Preclinical imaging techniques comparable to clinical ones can improve the translation of findings from animal models to humans in line with the 3Rs. The validation of non-invasive preclinical imaging methodologies allows us to gain insights into the pathogenesis and progression of disease, as well as therapeutic responses, enhancing the quantity and statistical validity of information and reducing the number of animals used and experimental variability. Optimizing preclinical imaging methods and avoiding experimental biases related to animal care and use are crucial for obtaining reliable and reproducible results, thus improving the translation of preclinical imaging results to clinical application.

Do you want to contribute to our 2026 Special Issue?

We are looking forward to receiving your contributions!

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. Journal of Imaging 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 1800 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.

We compared the results of brain magnetic resonance image (MRI) segmentation across a longitudinal dataset spanning mouse adulthood using an atlas-based approach and deep learning. Our results demonstrate that deep learning performs similarly yet faster than more established segmentation methods, even when computational resources are limited. Both methods enabled the large-scale analysis of a cohort of C57Bl6/J healthy mice, revealing sex-dependent morphological differences in the aging brain. These findings highlight the potential use of deep learning for high-throughput, longitudinal neuroimaging studies and underscore the importance of considering sex as a biological variable in preclinical brain research.

Metabolic dysfunction-associated steatotic liver disease (MASLD) is one of the most common chronic liver disorders worldwide and can lead to inflammation, fibrosis, and liver cancer. To better understand the impact of an unbalanced hypercaloric diet on liver phenotype in impaired autophagy, the study compared C57BL/6J wild type (WT) and MAPK15-ERK8 knockout (KO) male mice with C57BL/6J background fed for 17 weeks with “Western-type” (WD) or standard diet (SD). Liver features were monitored in vivo by high-frequency ultrasound (HFUS) using a semi-quantitative and parametric assessment of pathological changes in the parenchyma complemented by computer-aided diagnosis (CAD) methods. Liver histology was considered the reference standard. WD induced liver steatosis in both genotypes, although KO mice showed more pronounced dietary effects than WT mice. Overall, HFUS reliably detected steatosis-related parenchymal changes over time in the two mouse genotypes examined, consistent with histology. Furthermore, this study demonstrated the feasibility of extracting quantitative features from conventional B-mode ultrasound images of the liver in murine models at early clinical stages of MASLD using a computationally efficient and vendor-independent CAD method. This approach may contribute to the non-invasive characterization of genetically engineered mouse models of MASLD according to the principles of replacement, reduction, and refinement (3Rs), with interesting translational implications.

In this work, the authors compared microCT and in vivo ultrasonography in terms of accuracy and efficacy for measuring the volume of various organs in mice. Two quantification protocols were applied: ellipsoidal volume measuring maximum diameters in all three axes in both imaging systems and manual delineation of organ borders in microCT studies. The results were compared with ex vivo volumes. In general, both imaging techniques and quantification protocols are accurate, but ultrasound is faster in both acquisition and analysis. The only accurate method for heart volume measurement is manual segmentation on microCT. For the ovary, none of the techniques and protocols had a positive correlation with ex vivo volume. The three-diameter method can be used for ellipsoid organs because of its rapidity, but for more irregular structures, manual segmentation is recommended, although it is time-consuming. Full article
