Abstract：
OBJECTIVE: Current ultrasound (US) Doppler techniques cannot demonstrate the vascularization of the dermis. The purpose of this study was to investigate whether the new Superb Vascular Imaging (SMI) and Microvascular Flow (MV-Flow) techniques improve the detection of normal dermis vessels. SMI and MV-Flow were compared side-by-side to conventional power-Doppler (PD) imaging.
METHODS: By using US, 50 healthy volunteers were evaluated at level of five body areas: forehead, forearm, palm, buttock, and thigh. Two off-site operators evaluated the images to assess the difference between SMI and PD imaging and between MV-Flow and PD imaging in terms of dermis flow amount. A 0-3 scoring system was adopted.
RESULTS: SMI scored grade 0 in 0% of body areas, grade 1 in 58%, grade 2 in 33%, and grade 3 in 9%. In comparison with SMI, PD scored grade 0 in 38% of body areas, grade 1 in 56%, grade 2 in 6%, and grade 3 in 0%. MV-Flow scored grade 0 in 0% of body areas, grade 1 in 52%, grade 2 in 43%, and grade 3 in 6%. Comparted to MV-Flow, PD scored grade 0 in 53% of body areas, grade 1 in 34%, grade 2 in 13%, and grade 3 in 0%. The difference in terms of sensitivity was statistically significant for all the body areas investigated.
CONCLUSIONS: We found both SMI and MV-Flow to be superior to PD imaging and capable to demonstrate normal vascularization of the dermis.

摘要：
目的：当前的超声（US）多普勒技术无法证明真皮的血管化。这项研究的目的是研究新的超血管成像（SMI）和微血管流量（MV-Flow）技术是否可以改善正常真皮血管的检测。将SMI和MV-Flow与常规功率多普勒（PD）成像并排进行比较。
方法：使用US，50名健康志愿者在五个身体区域的水平进行了评估：额头，前臂,棕榈,臀部,还有大腿.两名场外操作人员评估了图像，以评估SMI和PD成像之间以及MV-Flow和PD成像之间在真皮流量方面的差异。采用0-3评分系统。
结果：SMI在0％的身体区域得分0级，58%的一年级，33%的2级，和三年级的9%。与SMI相比，PD在38%的身体区域得分0级，56%的一级，6%的2级，和0％的3级。MV-Flow在0%的身体区域评分为0级，52%的一级，43%的2级，3级占6%。与MV-Flow相比，PD在53％的身体区域获得0级，34%的一级，13%的2级，和0％的3级。对于所研究的所有身体区域，灵敏度方面的差异具有统计学意义。
结论：我们发现SMI和MV-Flow均优于PD成像，并且能够显示真皮的正常血管形成。
