To assess the influencing factors of transtemporal window quality and identify patients suitable for transcranial sonography (TCS) examination in two-dimensional imaging.
In this cross-sectional study, TCS was performed in 161 consecutive patients through the temporal bone window (TBW) in the neurology or neurosurgery department. Each patient's sex, age, height, weight, and temporal bone thickness (TBT) were collected. After examination, the patients were divided into two groups: TBW success and TBW failure. The data were statistically compared between the two groups.
Among the studied population, the total TBW success rate was 80.1% (95% confidence interval [CI]: 74-86). The TBW success rate was 91.4% (95% CI: 85-98) in males and 70.9% (95% CI: 61-81) in females (p = .001). Sex (p = .001), age (p = .002), height (p = .047), and TBT (p < .001) showed significant differences between the TBW success and failure groups. In males, only TBT (p = .001) showed a significant difference; in females, age (p < .001) and TBT (p = .003) showed a significant difference. The area under the receiver operating characteristic curve (AUC) of sex, age, and TBT and their combination was 0.686, 0.659, 0.842, and 0.922 (p < .001), respectively. The AUC of the combination of parameters was significantly greater than that of age and sex alone (p = .007; p = .0002) but not greater than that of TBT (p = .090).
The TBW success rate varied with sex, age, height, and TBT. Males, younger patients, taller patients, and patients with a thinner temporal bone tended to be more suitable for the examination by TCS.
评估经颞窗(transcranial sonography，TCS)二维成像(transcranial sonography，TCS)质量的影响因素，并确定适合 TCS 检查的患者。
本横断面研究对神经科或神经外科经颞骨窗(transcranial sonography，TCS)进行了 161 例连续患者的检查。收集每位患者的性别、年龄、身高、体重和颞骨厚度(temporal bone thickness，TBT)。检查后，将患者分为两组：颞窗成功组和颞窗失败组。对两组数据进行统计学比较。
在研究人群中，总颞窗成功率为 80.1%(95%置信区间[CI]:74-86)。男性颞窗成功率为 91.4%(95%CI:85-98)，女性为 70.9%(95%CI:61-81)(p=.001)。性别(p=.001)、年龄(p=.002)、身高(p=.047)和 TBT(p<.001)在颞窗成功组和失败组之间有显著差异。在男性中，只有 TBT(p=.001)有显著差异；在女性中，年龄(p<.001)和 TBT(p=.003)有显著差异。性别、年龄和 TBT 及其组合的受试者工作特征曲线下面积(area under the receiver operating characteristic curve，AUC)分别为 0.686、0.659、0.842 和 0.922(p<.001)。参数组合的 AUC 显著大于年龄和性别单独的 AUC(p=.007；p=.0002)，但不大于 TBT 的 AUC(p=.090)。
颞窗成功率随性别、年龄、身高和 TBT 而变化。男性、年轻患者、高个子患者和颞骨较薄的患者更适合 TCS 检查。
