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.
