Heavy monsoon rains in Mumbai have led to a sharp rise in neurocysticercosis cases caused by tapeworm infection in the brain.

The average brain dose per head or neck CT in 2012-2014, 38 mGy, was associated with excess brain cancer risk compared with a brain dose of 0 mGy (RR 1.5, 95% CI 1.2-2.0).

Qualitative whole-brain CT perfusion achieved 93.6% sensitivity and 92.3% specificity. CT angiography sensitivity ranged from 75.5–87.3%, while specificity held near 90% across scales.
