Ultrasonically guided punctures. A modified technique

P G Lindgren

    Radiology
    |October 1, 1980
    PubMed
    Summary
    This summary is machine-generated.

    Ultrasound-guided punctures using a dynamic sector scanner and needle-guide allowed real-time visualization of needle passage in 59 patients. This enabled precise correction of needle direction during procedures involving cysts and solid tissues.
