Brain tumours are detected through Ct scans, MRI’s, X-rays and angiograms. The New Technology With the advancement of science and technology, the image quality of a CT scan has drastically improved.

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.

Patients who underwent at least one head/neck CT scan exhibited significantly higher risk for childhood brain tumors as those who did not undergo head/neck CT scans (OR = 2.84; 95% CI, 1.12-7.19).
