Sonography is a diagnostic and therapeutic technique that is noninvasive, inexpensive, and provides real-time images. However, therapeutic treatments require a higher intensity beam than their diagnostic counterparts. High-intensity focused ultrasound (HIFU) treats tumors thermally and nonthermally through hyperthermia and cavitation. The procedure offers an option for oncology patients who are unable to receive traditional therapies. This article describes fundamental ultrasound properties, how the intensity of the ultrasound beam can be manipulated, and thermal and mechanical effects of the ultrasound beam on tissues.
This quiz is the companion to the column, "Nanoparticle-Enhanced Synergistic High-Intensity Focused Ultrasound," which appears in the January/February 2021 Radiologic Technology journal.
This activity may be available in multiple formats or from different sponsors. ARRT regulations state that an individual may not repeat a self-learning activity for credit if it was reported in the same biennium.
