This is a non-contrast CT brain from GMERS Medical College & Hospital, Gandhinagar, patient name Hiraben Thakor (ID 29632). Here is a systematic interpretation:
CT Brain — Systematic Interpretation
Technical Details
- Modality: Non-contrast CT (NCCT) head
- Scanner: Aquilion Lightning (Toshiba/Canon)
- Plane: Axial, sequential slices from skull base to vertex
- Window: Brain window (W/L ~80/35 HU — standard soft tissue)
Slice-by-Slice Review (Inferior → Superior)
Rows 1–2 (Skull base / posterior fossa):
- Cerebellar hemispheres appear symmetric with no obvious hyperdensity or hypodensity
- Brainstem is midline, no focal lesion visible
- Basilar cisterns appear patent (no effacement)
- No evidence of posterior fossa hemorrhage
Row 3 (Supratentorial — basal ganglia level):
- Bilateral basal ganglia (caudate, lentiform nuclei) appear symmetric in density
- Internal capsules appear intact
- Thalami symmetric
- Lateral ventricles visible and appear mildly prominent — may suggest mild cerebral atrophy or hydrocephalus (age-dependent correlation needed)
- No obvious hyperdense lesion (acute hemorrhage) at this level
Rows 4–5 (Ventricular level / centrum semiovale):
- White matter density appears relatively preserved
- Cortical sulci appear mildly prominent bilaterally — consistent with cortical atrophy, age-related or pathological
- No midline shift appreciated
- No periventricular hypodensity suggesting significant edema
Row 6 (Vertex / high convexity):
- Cortical sulci again mildly prominent
- No subdural or epidural collections identified
- No obvious hyperdense lesion
Key Observations
| Finding | Impression |
|---|---|
| Symmetry of parenchyma | Bilateral — no lateralizing lesion obvious |
| Midline shift | None |
| Acute hemorrhage (hyperdensity) | Not identified on available views |
| Basal cisterns | Patent |
| Ventricles | Mildly prominent — ?atrophy |
| Cortical sulci | Mildly prominent — ?generalized atrophy |
| Extra-axial collections | None identified |
| Posterior fossa | No gross lesion |
| Bone windows | Not assessable from this photo |
Impression
The CT brain appears largely within normal limits for age, with:
- No acute intracranial hemorrhage identified
- No space-occupying lesion or midline shift
- Mild cortical and central atrophy — age-related changes (clinical correlation with patient age required)
- Patent basilar cisterns — no features of raised intracranial pressure
Caveats
- This interpretation is based on a photograph of films on a light box — image quality and contrast resolution are significantly limited compared to viewing on a PACS workstation
- Bone windows, soft tissue detail, and subtle hypodensities (early infarct, small contusions) can easily be missed
- Formal radiologist reporting is essential for clinical decision-making
- If there is a specific clinical concern (stroke, trauma, headache, seizure), targeted windowing on original DICOM data is required
