Abstract
The aim of this study was to evaluate the efficacy of Doppler ultrasonography (US) with very high frequency transducers on assessing soft-tissue masses.We performed sonographic evaluation with an ATL HDI-5000 equipped with a 12.5-MHz linear transducer. Images were obtained in 70 patients admitted to our hospital. We applied Sono-CT as a new variation of compound sonography. Sono-CT provides compound images by combining the images obtained by electronically directing the transducer to scan from multiple angles.In this study, we found that US was able to depict softest tissue masses in detail. All tumors were shown as hypoechoic masses, except lipoma. Particularly, US was useful to diagnose certain neural or fatty tumors, and it was proven to help modality the most in the diagnosis of glomus tumors, since its vascularity can easily be detected using this device. In addition, US was not hampered by metal-induced artifacts. Moreover power (color) Doppler imaging was a valuable adjunct in differentiating malignant tumors from benign ones. US offers many advantages in the assessment of soft-tissue masses. This examination is thought to be sensitive, widely available, noninvasive, and less expensive.
