Choice of marker

The Gold Anchor™ marker is available in two different diameters, Ø 0.28 mm and Ø 0.40 mm, and two different lengths, 10 mm or 20 mm, resulting in four different versions. Choice of marker depends on the user preferences regarding visibility, artifacts and dose perturbation. Learn more >


Choice of needle

25 gauge needle

GA150 is recommended whenever the target can be reached with that needle, e.g. for most cases in lung, liver, pancreas, kidney, adrenal gland, oligomets in abdomen and inguinal metastases. The reason for recommending GA150 is that it is thinner than the other needles. GA150 is thereby even safer to use.

GA150 can also be used to transfer 0.28 mm diameter markers over into the needle tip of a 22G EBUS-TBNA needle or a 22G EUS-FNA needle to enable marker implantation through endoscope.

GA80 is mostly used for breast and for marking other superficial leisions.

GA150X provides an alternative to GA150 for those cases in which a stiffer needle is beneficial, e.g. in cirrhotic liver, or when the 0.40 mm diameter marker is preferred. GA150X can also be used to transfer 0.40 mm diameter markers over into the needle tip of a 19G EBUS-TBNA needle or a 19G EUS-FNA needle to enable marker implantation through endoscope.

GA200 is mostly used for transrectal implantation in prostate (since the longer needle is required for use with the probe) and for gynecology treatments. However, in certain cases some doctors may prefer GA200 also for abdominal and thoracic targets since it is more rigid/stable than the GA150.

GA250 is developed for ultrasound probes for transrectal insertions with needle guides that require a 25 cm needle.

20 gauge needle

fiducial marker needle 20G

GA200X is mostly used for gynecology treatments and by those that prefer a stiffer needle for transperineal implantation in prostate.

GA350 is for use in bladder and rectal wall, through rigid cystoscope/rectoscope.
