Magnetic resonance imaging (MRI) is a noninvasive imaging technique that today constitutes one of the main pillars of preclinical and clinical imaging. MRI’s capacity to depict soft tissue in whole specimens ex vivo as well as in vivo, achievable voxel resolutions well below (100 μm)3, and the absence of ionizing radiation have resulted in the broad application of this technique both in human diagnostics and studies involving small animal model organisms. Unfortunately, MRI systems are… 

A dataset comprising 141 magnetic resonance imaging scans of 98 extant sea urchin species

It is argued that publicly available digital anatomical and morphological data gathered during experiments involving non-invasive imaging techniques constitute one of the prerequisites for future large-scale genotype—phenotype correlations.

Digital Three-Dimensional Imaging Techniques Provide New Analytical Pathways for Malacological Research

Abstract: Research on molluscan specimens is increasingly being carried out using high-throughput molecular techniques. Due to their efficiency, these technologies have effectively resulted in a

X‐ray computed tomography and its potential in ecological research: A review of studies and optimization of specimen preparation

It is found that for the interests of ecological studies, X‐ray computed tomography is useful when the tissue or structure of interest has sufficient contrast that allows for an automatic or semiautomatic segmentation, and that reconstruction schemes which exploit phase contrast can yield enhanced image quality.

Non-invasive lipid measurement in living insects using NMR microscopy

It is demonstrated exemplarily in the European spruce bark beetle that NMR can be efficiently used to quantify absolute fat and water content in living insects and enables future research to address questions where single individuals have to be measured several times, which is not possible with conventional destructive methods.

Combined visualization of echinoderm hard and soft parts using contrast-enhanced micro-computed tomography

Results from an application of contrast-enhancement of micro-computed tomography to representative species from all five extant higher echinoderm taxa show that the combined visualization of echinODerm soft and hard parts can be readily accomplished using contrast- enhanced µCT in all extant echinoderms taxa.



Anatomy of a live invertebrate revealed by manganese-enhanced Magnetic Resonance Imaging

It is reported that systemically administered manganese can act as an effective MRI contrast agent for quick and non-invasive imaging of the nervous system and other complex anatomical structures in a small aquatic animal.

Broad application of non-invasive imaging techniques to echinoids and other echinoderm taxa*

The workflow established to generate three-dimensional models of sea urchins and the suitability of non-invasive imaging techniques for the study of other echinoderm taxa is assessed based on multimodal datasets of representative species.

Magnetic resonance imaging in entomology: a critical review

It is shown that MRM has been successfully applied in studies of parasitology, development, metabolism, biomagnetism and morphology, and the advantages and disadvantages relative to other imaging techniques are discussed.

In vivo magnetic resonance microscopy of brain structure in unanesthetized flies.

Non-invasive diagnostics in fossils - Magnetic Resonance Imaging of pathological belemnites

It is demonstrated that MRI can likewise be applied to fossilized biological samples and help in elucidating paleopathological and paleoecological questions and evidence is presented that the frequently observed anomalous apical collar might be indicative of an inflammatory disease.

Applications of Chemical Shift Imaging to Marine Sciences

Applications of CSI to marine samples are reported and a technique to study in vivo glycine metabolism in oysters using 13C MRS 12 h after immersion in a sea water chamber dosed with [2-13C]-glycine is described, the first report of 13C CSI in a marine organism.

Three-dimensional Magnetic Resonance Imaging of fossils across taxa

Three-dimensional MR image series acquired from intact non-pathological invertebrate, vertebrate and plant fossils reveal a host of anatomical details and highlight the potential of MR techniques to effectively complement existing methodological approaches for palaeontological investigations in a wide range of taxa.

Magnetic resonance microscopy of the adult zebrafish.

This is the first report of the application of high resolution MRM to study detailed anatomical structures in adult zebrafish and it revealed many anatomical details in the entire intact zebra fish at a magnetic field strength of 9.4 T.
