N2 - The purpose of this study was to determine if tissue harmonic imaging (THI) produced diagnostic images more frequently than conventional sonography. A prospective study was performed on 33 patients, to compare the diagnostic value of THI with conventional sonography. Each examination was performed using THI (transmit frequency=2.0MHz, receive frequency=4.0MHz) and conventional sonography at 2.5 and 4.0 MHz. The different sonographic techniques were then graded as to whether they produced diagnostic images. THI produced diagnostic images in 33 of 33 examinations (100%), 2.5 MHz conventional sonography produced diagnostic images in 26 of 33 examinations (79%), and 4.0 MHz conventional sonography produced diagnostic images in 26 of 33 examinations (79%). THI produced diagnostic images significantly more frequently than 2.5 MHz conventional sonography (p=.0233) and 4.0 MHz conventional sonography (p=.0233). The THI technique produced diagnostic images more frequently than conventional sonography.
