cerebrospinal fluid suppression
MRI technique that reduces signal from cerebrospinal fluid to enhance visualization of brain tissue and pathology.
Full Definition
Cerebrospinal fluid (CSF) suppression is an MRI technique that selectively reduces signal intensity from CSF while preserving signal from brain parenchyma. This is typically achieved through fluid-attenuated inversion recovery (FLAIR) sequences or other specialized pulse sequences. CSF suppression enhances the conspicuity of periventricular lesions, cortical abnormalities, and other pathology that might otherwise be obscured by the bright CSF signal in conventional T2-weighted images.
Usage
Usage note: Spell out 'cerebrospinal fluid' on first use; may abbreviate to 'CSF suppression' in subsequent references.
In Context
- "FLAIR sequences with cerebrospinal fluid suppression clearly delineated the periventricular lesions." — Radiological assessment
- "The protocol incorporated cerebrospinal fluid suppression to improve detection of cortical abnormalities." — Clinical imaging guidelines
