摘要

Background

Brainshift can hamper the accuracy of neuronavigation systems in intra-axial tumor surgery. Correction of brainshift becomes imperative to avoid loss of accuracy and erroneous assessment of residual tumor as well as its relationship to critical eloquent substrates.

Method

This paper describes a case of a frontal tumor close to motor cortex. Workflow for rigid image fusion (RIF) based iUS-MR correction of brainshift is demonstrated highlighting its accuracy and clinical value in assessing tumor margins as well as functional boundaries.

Conclusion

iUS-MR fusion provides a cost-effective, accurate and practical solution for observation and correction of brainshift.
