The value of ultrasound harmonic imaging in the diagnostics of the abdomen.
The tissue harmonic imaging (THI) is a new modality of ultrasonograph examination. The harmonic mode is characterized by a lower level of artifacts, due to reduction of side lobes energy and narrowed beam. The penetration in harmonic mode is also improved, so the visualization of deeper structures is often better. The assessment of liquid structures such as gallbladder, urinary bladder or large vessels and their pathologies is usually improved in the harmonic mode. The evaluation of cystic lesions, and differentiation cystic lesions and the hipoechogenic pathologies is easier in THI. Gallbladder stones localized in the gallbladder cervix are better evaluated in the harmonic mode. So the tissue harmonic imaging should be a part of standard ultrasonographic examination.
