NMR-kompatible Biopsievorrichtung mit einer Spitze, die im Bild einen Artefakt erzeugt

摘要

A biopsy device which is compatible for use with a magnetic resonance imaging machine. The device includes a non-metallic elongated substantially tubular needle (30) having a distal end, a proximal end, a longitudinal axis therebetween, and a port (36) on the elongated needle for receiving a tissue sample. The device further includes a sharpened distal tip (60) for insertion within tissue. The sharpened distal tip is attached to the distal end of the needle and at least partially comprises a material (90) which will leave an artifact under magnetic resonance imaging.
