Resection of soft tissue sarcomas with intra-operative magnetic resonance guidance.
OBJECTIVE
To report on a preliminary series of magnetic resonance (MR)-guided sarcoma resections.


METHODS
Three patients with the skin sarcoma dermatofibrosarcoma protuberans underwent MR-guided resection.


RESULTS
The extent of the tumor at MR imaging was greater in each case than suggested by clinical examination. Adequate resection margins were planned using short Tau inversion recovery (STIR) sequences and intra-operative imaging was used to confirm complete tumor excision. Histological examination confirmed clear surgical margins of at least 1 cm in each case.


CONCLUSIONS
We believe this technique may reduce the incidence of specimen margins positive for tumor following resection, and consequently reduce the need for further excisional surgery.
