简要总结

White matter hyperintensities (WMH) are one of the small vessel disease-related MRI characteristics of both cerebral amyloid angiopathy (CAA) and hypertensive arteriopathy (HA). WMH tend to show a peri-basal ganglia pattern in HA, whereas a multiple subcortical spots pattern can be observed in CAA. Periventricular WMH (PVWMH) have been reported to be posterior predominant using a semiautomated segmentation method and logarithmic transformation, not used in daily clinical practice. In these studies including CAA patients, patients initially presented with haemorrhage-related symptoms. In another study analysing PVWMH and cerebral amyloid evidence in patients with mild cognitive impairment, frontal PVWMH burden was associated with high uptake on florbetapir-PET whereas parietal and occipital PVWMH burden was associated with low CSF-amyloid-beta.

The aim of this study is the descriptive comparative analysis of the distribution of PVWMH between CAA and HA patients with radiological tools available in daily practice.

结局指标

主要结局

Distribution of PVWMH

时间窗: Base line, Day 0

Maximal distance between the outer PVWMH border and the border of the lateral ventricle (on the axis oriented at 90° to the border of the ventricle)

Distribution of PVWMH - total PVWMH extent.

时间窗: Base line, Day 0

The sum of the PVWMH measurements around the four ventricles horns (i.e. bilateral anterior and posteriors horns) resulted in total PVWMH extent.

Corpus callosum (CC) WMH

时间窗: Base line, Day 0

Distance between the border of the third ventricle and the outer border of the WMH on the rostro-caudal axis, resulting in anterior and posterior CC-PVWMH extent measurements.

Corpus callosum (CC) WMH - total CC-PVWMH extent.

时间窗: Base line, Day 0

The sum of the anterior and posterior CC-PVWMH measurements resulted in the total CC-PVWMH extent.

Anterior PVWMH

时间窗: Base line, Day 0

Comparison of anterior PVWMH between CAA group and HA group.

Posterior PVWMH

时间窗: Base line, Day 0

Comparison of posterior PVWMH between CAA group and HA group.

Total PVWMH

时间窗: Base line, Day 0

Comparison of total PVWMH between CAA group and HA group.

anterior CC-PVWMH

时间窗: Base line, Day 0

Comparison of anterior CC-PVWMH between CAA group and HA group.

Total PVWMH and posterior/anterior CC-PVWMH ratio

时间窗: Base line, Day 0

Comparison of total PVWMH and posterior/anterior CC-PVWMH ratio between CAA group and HA group.

Posterior/anterior PVWMH ratio

时间窗: Base line, Day 0

Comparison of the posterior/anterior PVWMH ratio between CAA and HA groups.

Posterior CC-PVWMH

时间窗: Base line, Day 0

Comparison of posterior CC-PVWMH between CAA group and HA group.

Ratios

时间窗: base line, day 0

Calcul of posterior/anterior ratios for both the PVWMH and CC-PVWMH
