摘要:
Among other things, there is disclosed embodiments of biopsy needles having improved radiological visualization properties. Exemplary needles include an outer cannula and a stylet slidable within the cannula. At least a portion of the stylet is radiologically contrasting to at least a part of the cannula. When the stylet is extended from the cannula within the patient, the clinician can observe radiologically where the extended portion of the stylet is, because of the radiological contrast between the stylet and cannula. The clinician can compare that contrasting area to the tissue of interest, to assure that the needle is properly placed.
