Early detection is essential for effective intervention, but current diagnostic methods that enable early diagnosis in clinical practice rely on invasive or costly biomarker scanning. This study aimed to explore the utility of 7T MRI in assessing hippocampal subfield volumes and their correlation with cerebrospinal fluid (CSF) biomarkers in prodromal AD.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Fifty\u2010six participants, including AD patients and healthy controls, underwent 7T MRI scanning.

Additionally, the volume of the entorhinal cortex (ERC) correlated significantly with CSF amyloid\u2010\u03b2 levels, suggesting ERC's potential as a proxy CSF amyloid\u2010\u00df measurement. Conversely, no significant associations were found between CSF 181\u2010Phosphorylated\u2010tau or total tau levels and any hippocampal subfield volumes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>These findings show the potential use of 7T MRI, particularly in ERC assessment, as a biomarker for early AD identification.
