Thanks for the update Bafanguy - it was only a question of time before the FDA approved one of the devices
The template biopsy involves a navigation system to target the biopsies from the imaging obtained at MRI. It is a large number of large needles and it is essential the patient is completely still
In the UK this is done under a GA not the IV sedation used for colonoscopy and certainly not oral tranquillisers. The US has historically done quite horrendous procedures awake, in part due to a lack of anesthesiologists but also because Americans had a real fear of anesthesia having been told the army staff sergeants who administered the newly introduced pentothal on US casualties at Pearl Harbor killed more GIs than the Japanese.
However that was yesterday. Today I would tell anyone having this procedure to have a general anaesthetic both for their own comfort and for accuracy. No ifs. No buts.
