Basic reading computed tomography (ct) of brain

This document provides guidance on interpreting a basic computed tomography (CT) scan of the brain. It outlines a systematic approach by comparing left and right sides, looking for midline shifts, and reviewing cross-sectional anatomy at each slide. Key anatomical landmarks are identified, including gray matter, white matter, ventricles, cisterns, sulci and fissures. Specific pathologies like subdural hematomas and physiologic calcifications are also addressed.

Basic Reading Computed Tomography ( CT ) of Brain By…Ext. วรปรัชญ์ สามารถ
Systemic Approach to Head CT Interpretation Symmetry – Compare left and right side of the cranium Midline – Look for midline shift Cross-sectional anatomy – Review anatomical landmark for each slide Brain tissue : gray matter, white matter , intracerebral lesions CSF space : ventricle, basal cistern, cortical sulci, fissure Skull and soft tissue : scalp swelling, fractures, sinuses, orbit Subdural windows : Look for blood collection adjacent to the skull Bone windows : Skull, orbit and sinuses, intracranial air
