In a neuronavigational surgery, computers help plot the shortest and safest path to the problem area in the brain. An MRI is used along with a neuronavigation suite (which costs almost Rs 1 crore) to do so. Like a doctor explained, it's a bit like charting a spacecraft's path through space but the difference is that, inside the brain, every millimeter counts. Only a handful of Indian hospitals boast of such a suite.
