CT HEAD ANATOMY Axial slice of a non contrast CT head at the level of the basal ganglia 👨🏽‍💻The basal ganglia are a group of structures including the caudate and lentiform nucleus in the cerebrum as seen here, the substantia nigra within the midbrain and the subthalamic nuclei in the diencephalon 👨🏽‍💻Simply put the basal ganglia is important in motor function, facilitating movement and inhibiting competing movements. It is depletion of dopaminergic neurons within the substantia nigra that

Risks of CT Scans New research shows that CT scan radiation may be responsible for 1 in every 20 cancer cases in the U.S. That’s over 103,000 cancers per year—from the very machines used to detect disease. Most people have no idea these scans come with ionizing radiation strong enough to damage DNA. And when multiple scans are done—especially on children—the risk skyrockets. Some estimates show up to 20 cancers per 1,000 scans for kids under 1. Safer options (if applicable): MRI Ultrasound Full-
