What criteria are used to determine whether or not a lesion is amenable to IPNB?
When contemplating IPNB, there are several things to consider. For a lesion to be amenable to IPNB, it must be visible on one of the imaging modalities discussed above. Additionally, there must be a safe route to access the lesion without likely damage to vital organs or vascular structures. Vascular lesions should not undergo percutaneous needle biopsy. If a lesion is considered amenable to IPNB, patients must then be assessed to make sure they are candidates for this procedure.
