Product Principles

Preclinical MRI enables a multitude of facets of basic research, disease, and treatment studies to be illuminated. Non-invasive in vivo imaging of small animals and rodents provides structural and functional information with high spatial and temporal resolution. 

Brief Introduction

Leading scientists worldwide are taking their research closer to the molecular and cellular level thanks to BioSpec?. Designed for the emerging market of preclinical imaging and molecular MRI, its innovative modular concept enables virtually any small animal MR imaging application in life science, biomedical, and preclinical research. 

BioSpec? already brings proven performance, safety, convenience, and future-proof cost-effective operation to over 600 labs worldwide. With our new multimodal animal platforms and accessories and our latest generation ParaVision? software more users than ever can access a new level of research quicker than they think.

Application Fields

With the power to conduct limitless imaging applications, BioSpec?opens up a whole new world of applications. Customers across the world undertake daily investigations into: 


  • Angiography - flow contrast and flow analysis of the velocity of each voxel for glioblastoma and aneurysm studies

  • Cardiology - investigation of cardiac strain, ejection fraction, and septum defects, using triggered sequences or Bruker’s patented IntraGate for navigator based retrospective gating

  • Diffusion - visualization of disturbed pathology, such as in multiple sclerosis, epilepsy, and stroke tumors

  • fMRI - insight into the brain‘s function 

  • Molecular MRI - imaging at the cellular level 

  • Perfusion - with and without CA for tumor- detection, -neoangio genesis, and -vascularization, and disruption of the blood brain barrier 

  • Spectroscopy – quantification of metabolic disorders and long term changes in metabolic processes

Application

1、DTI Fibers

Brain connectivity studies in small animals are
challenging but can be achieved using state-ofthe-art MRI technologies for acquisition, such as the 7 T BioSpec? with MRI CryoProbe. Highresolution DTI MRI and fiber tracking of the living mouse brain delineate the organization of the
fiber tracts.


Acquisition details: MRI CyroProbeTM at 7 Tesla,
DTI-EPI, diffusion directions: 30, resolution:
(12.5 × 15.5 × 50) ?m?, scan time: 25 min.

2、Localized Spectroscopy

STEAM spectrum of the mouse brain acquired using the MRI CryoProbeTM at 15.2 Tesla. 

Acquisition details: STEAM, voxel size: (2 x 2 x 2) mm?, TR: 8 s, 128 averages, resolution enhancement with shifted Gauss filtering, TE: 1.1 ms, shift: 7%, broadening: 7 Hz

3、Cellular Imaging

Mesenchymal stem cells were labeled and used as markers for stroke regions. They are readily visible in T2- and T2*-weighted images both in vivo and ex vivo. Full 3D brain coverage enables quantification and volume rendering.
