Summary
Dynamic tracking of gadolinium contrast agents for cerebral perfusion imaging is now standard in neuroradiology. This technique aids in diagnosing conditions like stroke, vascular disease, and tumors.
Area of Science:
- Neuroradiology
- Medical Imaging
- Cerebrovascular Physiology
Background:
- Dynamic susceptibility contrast (DSC) imaging using gadolinium-based contrast agents (GBCAs) has transitioned from experimental research to routine clinical neuroradiologic practice.
- Understanding cerebral perfusion is crucial for diagnosing and managing various neurological conditions.
Purpose of the Study:
- To discuss the practical implementation of perfusion imaging protocols in neuroradiology.
- To highlight the role of postprocessing and quantitative interpretation in assessing vascular physiology and function.
- To introduce key clinical indications for cerebral perfusion imaging.
Main Methods:
- Dynamic tracking of a gadolinium-based contrast agent bolus.
- Implementation of standardized perfusion imaging protocols.
- Postprocessing and quantitative analysis of perfusion parameters.
Main Results:
- Cerebral perfusion imaging is now a routine diagnostic tool.
- Quantitative interpretation provides insights into vascular physiology.
- The technique is applicable to diverse clinical scenarios.
Conclusions:
- Dynamic cerebral perfusion imaging is an established and valuable tool in neuroradiology.
- Effective implementation relies on standardized protocols and quantitative analysis.
- Key applications include acute ischemia, chronic vascular disease, and tumor evaluation.
