Design outcomes

Primary

MeasureTime frame
In this study, to establish an evaluation method for the brain's lymphatic system, we will compare the individual assessment capabilities of the three evaluation methods in patients with obstructive sleep apnea syndrome and a normal control group. Additionally, we will examine the usefulness of a comprehensive evaluation combining all three methods.
