Magnetic resonance imaging-guided navigation with a thermoplastic shell for breast-conserving surgery.

摘要: Abstract Background The aim of this study was to evaluate the accuracy a magnetic resonance imaging (MRI) marking technique with drape-type thermoplastic shell for planning breast-conserving surgery (BCS). Methods A prospective review performed on 35 consecutive patients who underwent MRI in supine position and used specified technique. Eleven cases pre-operative chemotherapy 24 did not. After immobilizing breast mound shell, MRI, location lesion marked shell. Resection lines were dyed blue by indigo carmine, which pushed through pores Specimens obtained during BCS sliced into 5-mm contiguous sections, margin assessed each specimen. Cancer foci less than 5 mm from classified as positive. Results Of patients, 33 included analysis; 2 excluded due lack effect chemotherapy. these 25 (75.8%) had negative margins 7 (21.2%) positive margins. Conclusions Our may be useful evaluating extent tumors that determined alone. Long-term outcomes should evaluated further.
