Using an aubergine as a phantom for practicing stereotactic guided core biopsy

1H-MRS-guided stereotactic brain biopsy.

with a power of 0.8 and type I error probability of 0.05. Anyway, in our opinion, metabolic guidance may be rather useful during stereotactic biopsy of parenchymal brain tumors, and may be especially recommended for recurrent, particularly previously irradiated, neoplasms, or for sampling of the highly vascular lesions since in the latter cases, detection of the spectroscopic abnormalities outs...

Stereotactic Core Biopsy of the Breast.

Freehand biopsy guided by electromagnetic needle tracking: a phantom study.

PURPOSE To evaluate the overall accuracy and time spent on biopsy guided by electromagnetic needle tracking in a phantom compared with the standard technique of US-guided biopsy with an attached steering device. Furthermore, to evaluate off-plane biopsy guided by needle tracking. MATERIALS AND METHODS Three different series of biopsy were performed in a phantom: one with a steering device att...

Risk factors for cancellation of stereotactic large core needle biopsy on a prone biopsy table.

Among patients undergoing stereotactic needle biopsy of the breast on a prone biopsy table, a substantial proportion of planned procedures are terminated prematurely. This study was undertaken to identify risk factors for cancellation of these procedures and to derive a clinical rule for predicting cancellation. Risk factors for cancellation were assessed in a group of 476 consecutive patients ...
