Siemens Vida 3T MRI Scanner

Technical operation and safe work environment provided by clinically certified MR technologists.
Equipped with high-performance imaging coils (e.g., 64-channel head coil), for high-resolution and accelerated imaging.
Paired with functional MRI stimulation hardware and software from Nordic Neuro Lab.
Capable of performing a wide range of clinical and research techniques, including:
- High-resolution structural imaging (e.g., MSK, Brain)
- Spectroscopy
- Task-based, event-based, and resting-state Functional MRI (fMRI)
- Perfusion
- Anisotropic Diffusion Imaging
- Relaxometric parameter mapping
- MR Elastography

Imaging

Neuroimaging

All basic MRI for anatomical images (like T2WI, T1WI, GRE, etc), Neuro perfusion, DSC-based perfusion, DCE-based perfusion and permeability, Cerebral blood flow (2D and 3D ASL), Advanced less-distorted DWI, Selective excitement. DTI (B-value ranges from 0 -10000 s/mm2, directions 256) and fMRI (NordicNeuroLab fMRI and Visual system).

Abdominal Imaging

All standard sequences for anatomical imaging with or without fat suppression. All advanced sequences for liver imaging for determining fat and iron, MR Elastrography to determine liver fibrosis.

MSK

Basic sequences, T1, T2, T2* mapping. WARP and Advanced WARP (metal implant).

Vascular Imaging

Pre and post-contrast MRA. Post-contrast multiphasic MRA. MR-DSA. Arterial wall thickness and atherosclerotic plaques can be determined.

Cardiac Imaging

MRI is considered gold standard for myocardial thickness and changes in the relaxivity due to chemotherapy and other injury. T1- T2-, T2* maps can be created.

Magnetic Resonance (MR) Spectroscopy

Magnetic resonance (MR) spectroscopy is a noninvasive diagnostic test for measuring biochemical changes in the brain, especially the presence of tumors. MR spectroscopy compares the chemical composition of normal brain tissue with abnormal tumor tissue.
