Therefore, Dr. Ciechomska and her coinvestigators wanted to see if ultrasound would accurately identify the features of nerve compression in patients with CTS. They obtained ultrasound images of 126 wrists in 52 patients who had been diagnosed as having CTS by EMG. They also obtained ultrasound images of the wrists of 22 healthy people. They used the Aspen unit (Acuson, Aliso Viejo, California), which was equipped with a linear, wideband transducer at 6 to 11 MHz.

Ciechomska和她的研究同僚于是对超音波进行研究，确定超音波是否可以正确的侦测出腕隧道症候群患者受到压迫的神经；研究人员从52位患者处获取了126个手腕超音波造影，这些患者皆经肌电图证实患有腕隧道症候群；同时，研究人员也取得了22位健康者的腕部超音波造影以为对照；所使用的仪器为Aspen (Acuson公司，位于加州Aliso Viejo市)，配备一线性的宽频电能转换器，频率设定在6到11 MHz。

Finally, the Nuvi 265WT comes with a number of extras, including the Garmin Lock antitheft feature, a world clock, currency and measurement converters, and a calculator.
