This is a non-contrast CT scan of the brain for patient Prahladbhai Patel (ID: 25626) from GMERS Medical College & Hospital, Gandhinagar. The scan shows approximately 30 axial slices from the skull base to the vertex. Here is a systematic interpretation:
CT Brain — Systematic Interpretation
Technical Parameters
- Modality: Non-contrast CT (NCCT) brain
- Scanner: Aquilion Lightning (Toshiba/Canon)
- Slice thickness: 3.0 mm
- Window settings: W: 80 / L: 40 (standard brain window) and W: 150 / L: 40 visible on some cuts
- kV/mA: 120 kV / 135 mA (typical head protocol)
Row-by-Row Analysis (Inferior → Superior)
Row 1 — Skull Base / Posterior Fossa
- Cerebellum and brainstem appear symmetrical
- No hemorrhage or infarct visible in the posterior fossa
- Mastoid air cells appear clear bilaterally
- Orbits and globes appear normal
Row 2 — Posterior Fossa / Cerebellopontine angles
- Fourth ventricle appears normal in size and position — no hydrocephalus at this level
- Basilar cisterns (suprasellar, ambient, quadrigeminal) appear patent
- No evidence of subarachnoid hemorrhage in the basal cisterns
Row 3 — Suprasellar / Midbrain level
- Midbrain appears symmetric
- No midline shift
- Temporal horns of lateral ventricles are not dilated
Row 4 — Thalamus / Basal Ganglia level
- Bilateral basal ganglia (caudate, putamen, globus pallidus) appear symmetric and isodense — no hyperdensity to suggest hemorrhage, no hypodensity suggesting infarction
- Third ventricle appears normal in size
- Internal capsules appear symmetric
Row 5 — Lateral Ventricle Body level
- Lateral ventricles appear symmetric and normal in caliber
- No periventricular hypodensity (no leukoaraiosis)
- No intraventricular blood
Row 6 — Centrum Semiovale
- White matter appears homogeneous
- No focal hypodensity to suggest large territorial infarct
- No hyperdense lesion to suggest hemorrhage
Top Rows — High Convexity / Vertex
- Sulci appear appropriate for age
- No subdural or epidural collections identified
- Calvarium appears intact
Key Findings
| Feature | Finding |
|---|---|
| Intracranial hemorrhage | Not identified |
| Midline shift | None |
| Mass lesion | None identified |
| Infarct (acute hypodensity) | None identified |
| Hydrocephalus | None |
| Basal cisterns | Patent |
| Sulci/gyri | Appear age-appropriate |
| Bone windows | No fracture visible |
Impression
No acute intracranial pathology identified on this non-contrast CT brain. The study appears within normal limits. The parenchyma, ventricles, sulci, and basal cisterns all appear unremarkable.
