Preclinical MRI for Biomedical Imaging Laboratory（預臨床生物醫學磁共振成像實驗室）

Bruker BioSpec 3T MRI

At a translational field of 3 Tesla, this small animal scanner extends the range of multi-parametric, preclinical magnetic resonance imaging (MRI) in a compact design with the advanced cryogen-free magnet technology. It comprises of the latest MRI technology, software packages and multimodal options, such as positron emission tomography (PET). This 3T scanner can achieve a variety of biomedical imaging applications, such as anatomic relaxation imaging, angiographic imaging and imaging neurological functions using diffusion tension imaging and functional MRI. Moreover, it can perform molecular imaging using MRS and Chemical Exchange Saturation Transfer (CEST) MRI.

PDW

T1-weighted (T1W) image, T2-weighted (T2W) image and proton density-weighted (PDW) are three categories anatomic image which can provide different structural contrast. A short TR and short TE sequence is usually called T1-weighted; A long TR and long TE sequence is usually called T2-weighted; A long TR and short TE sequence is usually called PD-weighted. As we can see from above, we can acquire high-quality anatomic relaxation images on this 3T BioSpec MRI scanner.

Axial Coronal

Sagital

We can acquire high-resolution T2Wimages of a mouse body, which show the anatomy of the gastrointestical tract, liver, kidneys and spine at this 3T clini-cal field strength animal scanner.

Imaging for medical purposes involves a team which includes theservice of radiologists, radiographers (X-ray technologists),sonographers (ultrasound technologists), medical physicists, nurses,biomedical engineers, and other support staff working together tooptimize thewellbeing of patients, one at a time. Appropriate use ofmedicalimagingrequiresamultidisciplinaryapproach.
