Comprehensive Guide to Normal Brain Anatomy on CT Scans

Explore the intricate structures of the brain parenchyma, including the cerebrum, cerebellum, and basal ganglia, visible on CT scans. Learn about ventricles, cisterns, fissures, and sulci. Gain insights into subarachnoid spaces and examine the different lobes and their functions.

  2. 正常CT解剖

  3. 腦部解剖構造Brain Parenchyma(腦實質) • Cerebrum 大腦半球 • frontal lobe額葉 • temporal lobe葉 • parietal lobe頂葉 • occipital lobe枕葉 • Cerebellum小腦半球 • Basal ganglia, thalamus視丘 • Brainstem腦幹, midbrain中腦

  4. Subarachnoid spaces ( CSF spaces) 蜘蛛網膜下腔 • Ventricles (腦室) • lateral, 3rd, 4th ventricles • Cisterns (腦池) • suprasellar cisterns (碟鞍上腦池) • quadrigeminal cisterns (四疊體腦池) … • Fissures (腦裂) • Sylvian fissures • interhemispheric fissures… • Sulci (腦溝)
