    Diaqnostic ultrasound has become a radiology subspecialty. Ultrasonoqraphy(USG) is a procedure in which high-energy sound waves are bounced off internal tissues or organs and make echoes, which are picked up by the transducer and converted into an electrical signal and then into a real-time...

    Background. The aberrant cervical thymus is an uncommon entity to be considered in the differential diagnosis of neck masses in children, so a preoperative diagnosis has rarely been made. Objective. The purpose of this study was to assess the ultrasound features of aberrant cervical thymus and...

    Scanned at very high ultrasound frame rates, injectable microbubbles can be activated sequentially as isolated punctual sources of acoustic echoes. These signals can thus be localized far beyond the diffraction limit. The resolution improvement granted by Sono-Activated Ultrasound Localization...

    An encyclopedia entry for "echo-free" is presented. It is a medical term used in ultrasound scanning to denote a structure that does not give rise to reflections or echoes of ultrasound waves. For example, a cyst filled with clear fluid is echo-free.
