Figure 2 MRI comparison of lateral ventricular rim WMSA (yellow area) in a insomnia and a good sleeper A-C: A 44-year-old female with good sleep and no intracranial organic lesions, her T2-Flair high signal volume in lateral ventricular rim was 1.21 cm³, accounting for 9.34% of the region; D-F: 64-year-old male with insomnia for 1 year, his sleep efficiency was 69.3% detected by PSG and his T2-Flair high signal volume in lateral ventricular rim was 3.81 cm³, accounting for 23.15%.
