Rack for Image-Guided Fine Needle Aspiration (FNA) Marking

Developed by: Instituto de Investigación Sanitaria Galicia Sur

Description

Fine needle aspiration (FNA) is a medical procedure whose purpose is obtaining cellular samples from a specific area of the body, using images obtained by Computerized Axial Tomography (CAT) techniques as guidance. As a first approach, the FNA team generally uses centred lines of CAT for guidance in order to mark the desired area prior to the puncture and, as a second approach, an external radio-opaque metallic marker, such as a needle or a clip. However, these markers are the only external reference and give limited information regarding the best way to access the tissue of study. The access should be very precise to avoid several associated risks, such as puncturing other organs, repetition of CAT images (which implies exposing the patient to higher levels of radiation), and the need for more punctures to obtain a valid tissue sample.

In order to avoid such risks, a new external radio-opaque marker with ten standardized points of reference in the form of a rack has been designed. The rack is manufactured in silicone to avoid allergic reactions.
