Independence of extracellular tortuosity and volume fraction during osmotic challenge in rat neocortex

The Journal of Physiology, 2002
The structural properties of brain extracellular space (ECS) are summarised by the tortuosity (λ) and the volume fraction (α). To determine if these two parameters were independent, we varied the size of the ECS by changing the NaCl content to alter osmolality of bathing media for rat cortical slices.

Integrated motion-corrected extracellular volume fraction mapping reveals subtle extracellular remodeling in remote myocardium following chronic myocardial infarction

BMC Medical Imaging
Background Emerging evidence indicates that diffuse fibrosis in remote myocardium contributes to post-infarction ventricular remodeling, yet conventional late gadolinium enhancement (LGE) lacks sensitivity for extracellular matrix (ECM) quantification ...

Prediction of long-term survival in gastric cancer patients after immunotherapy based on CT-derived extracellular volume fraction

Frontiers in Oncology
BackgroundGastric cancer remains a leading cause of cancer-related mortality. While immune checkpoint inhibitors (ICIs) have emerged as promising therapies, their efficacy is hindered by the lack of robust patient-centric biomarkers.

Synthetic extracellular volume fraction as an imaging biomarker of the myocardial interstitium without blood sampling: a systematic review and meta-analysis

Journal of Cardiovascular Magnetic Resonance
: Background: The calculation of conventional extracellular volume fraction (ECV) requires blood hematocrit (Hct) measurement. Based on the relationship between Hct and blood T1 relaxivity for cardiac magnetic resonance (CMR), a synthetic ECV could be ...
