Examine the feasibility of introducing Arterial Spin Labelling Perfusion techniques to neuro-oncology protocols in a large tertiary MRI centre with a large neuro-oncollogy work load. To highlight the ease of obtaining ASL-PWIs with no offline processing. Explore the added value of Perfusion Weighted Images to improve diagnostic prognostication and confidence levels.
Arterial Spin Labelling (ASL) is a completely non-invasive MRI perfusion technique.
The technique utilisestrain of electromagneticpulses tolabel arterial blood water flowing to the brain.
Together witha control image,
acquired without labelling,itproduces information on cerebral blood flow.
The use of an endogenous tracer is an attractive pro in the controversial topic of MRI contrast agents. ASL can produce quantified data,
which is a valuable resource,however this requires offline...
Findings and procedure details
How we implemented the service. MRI Radiographers ata large tertiary MRI centre recieved in-house training from a clinical physicist and specialised radiographer supported by a Neuro-Radiologists with experience in the field. Training included identifying patients who could benefit from ASL during pre-screening checks,
how to perform ASL techniques and how to optimise patient position to ensure diagnostic scans. After a period of training and support,
radiographers were able to run the...
ASL techniques can be introduced to patient services in large scale practise .
ASL is a reliable,
lowcost and well tolerated technique.
After an initial introduction process,
ASL can be utilised with minimal disruption to already exsisting MR neuro-oncology services. ASL data has the potential for quantative analysis when required however ASL-PWI can add value to conventional images in the clinical setting.ASL-PWI can be produced and reviewed at the same time as conventional...
