High resolution – sonography in the diagnosis of liver metastases

Objective: High frequency ultrasound transducers have been helpful in certain settings of transabdominal ultrasound examinations, however their value in the diagnosis of metastatic liver disease has not yet been analyzed. The aim of this study was to evaluate the benefit of the additional use of a high-frequency ultrasound probe in finding additional suspicious liver lesions compared to the routine examination using a 3.5 MHz-transducer only. Subjects and Methods: 157 patients with underlying malignant disease were examined with a 3.5 MHz- and a high frequency transducer (with or without tissue harmonic imaging)…
