What is syngo ASL?

The Siemens unique product syngo ASL is based on the technique Arterial Spin Labeling (ASL). It uses the water in arterial blood as an endogenous contrast agent to evaluate perfusion non-invasively. syngo ASL provides unique insight into human brain perfusion and function physiology by evaluating cerebral blood flow (CBF). syngo ASL is capable of high spatial resolution perfusion imaging, making the technique very appealing in the evaluation of stroke, tumors, degenerative diseases and epilepsy, but also in basic neuroscience, e.g. for studies of functional CBF changes. syngo ASL is compatible with iPAT (integrated Parallel Acquisition Technique; GRAPPA) and takes only a few minutes, all without the use of any contrast agent! Inline technology improves your workflow by automatically computing relCBF maps without manual intervention. Fully automated results for a faster and more accurate diagnosis!

Clinical applications

Neuro:

• Imaging tumor perfusion and therapy monitoring
• Pediatric cerebral perfusion imaging (developmental radiology)
• Differential diagnosis of brain tumors (e.g. distinguish glioblastomas from metastases and CNS lymphomas depending on CBF values)
• Perfusion imaging of stroke and epilepsy evaluation
• Degenerative diseases such as dementia and Alzheimer’s disease
• Functional evaluation of the brain, e.g. in combination with BOLD techniques: changes in perfusion are more localized to the parenchyma, whereas BOLD changes are tied to the veins and venules

• Contrast-media-free quantitative CBF measurements with Inline relCBF map calculation
• Non-invasive perfusion evaluation of tumors in the brain, stroke, obstructive carotid artery disease, epilepsy, dementia etc.
• Functional evaluation of cerebral physiology
• Highly robust to head motion with built-in 3D PACE
• Fast additional diagnostic information in just a few minutes with syngo ASL and iPAT (GRAPPA)
