This research aimed to discuss the characteristics of benign paroxysmal positional vertigo (BPPV) and the correlation with cerebrovascular disease. An artificial intelligence algorithm under a parallel dual-domain concatenated convolutional neural network (PDDC-CNN) was proposed to process the images of magnetic resonance imaging (MRI). MRI, magnetic resonance angiography (MRA), and susceptibility weighted imaging (SWI) were performed on all 60 research objects with a 3.0 MRI scanner. The number of cases with cerebral microbleeds (CMBs), SWI image display of small veins, the number of lacunar infarctions, vertebral artery dominance, and vertebrobasilar morphology were observed in the two groups. The number of lacunar infarctions was 2.400 ± 3.358 and 0.672 ± 0.251, respectively, in the BBPV group with 30 cases and the control group with the other 30 cases. The positive rates of CMBs on SWI images were 48% and 27% in the BBPV group and the control group, respectively, and the average CMBs were counted as 1.670 ± 2.326 and 0.487 ± 0.865. CMBs were shown as round or oval lesions of conventional sequence deletion in the images with a diameter of less than 1.5 cm. SWI images of the BBPV group showed a significant increase in intracerebral small veins compared to those of the control group. The curvature of the vertebrobasilar artery in the BBPV group was significantly higher than that in the control group, and the curvature of the basilar artery was slightly higher than that in the control group. In conclusion, the MRI features of BPPV patients were related to their own microvascular lesions closely, and it was speculated that the cerebrovascular factors might play a dominant role in the early onset of BPPV.
本研究旨在探讨良性阵发性位置性眩晕（BPPV）的特征及其与脑血管病的相关性。采用一种基于并行双域串联卷积神经网络（PDDC-CNN）的人工智能算法对磁共振成像（MRI）图像进行处理。对所有 60 例研究对象在 3.0 MRI 扫描仪上进行 MRI、磁共振血管造影（MRA）和磁敏感加权成像（SWI）。观察两组脑微出血（CMBs）、SWI 显示小静脉数量、腔隙性梗死数量、椎动脉优势、椎基底动脉形态。BPPV 组 30 例和对照组 30 例的腔隙性梗死数量分别为 2.400±3.358 和 0.672±0.251。BPPV 组和对照组 SWI 图像上 CMBs 的阳性率分别为 48%和 27%，平均 CMBs 分别为 1.670±2.326 和 0.487±0.865。CMBs 在图像上表现为直径小于 1.5cm 的常规序列缺失的圆形或椭圆形病变。BPPV 组的 SWI 图像显示颅内小静脉明显增多。BPPV 组的椎基底动脉曲率明显高于对照组，基底动脉曲率略高于对照组。总之，BPPV 患者的 MRI 特征与自身微血管病变密切相关，推测脑血管因素可能在 BPPV 的早期发病中起主导作用。
