🩺 What is USG Cranium? USG Cranium, or Cranial Ultrasound, is a non-invasive imaging test that uses high-frequency sound waves to create images of the brain and its structures. It is most commonly performed in infants, especially newborns, because their fontanelles (soft spots) allow ultrasound waves to pass through the skull easily.

🧠 USG Cranium (Cranial Ultrasound) – Complete Details

⚙️ Purpose / Indications

Cranial ultrasound is mainly done to:

  • Detect intraventricular hemorrhage (IVH) – bleeding inside the brain’s ventricles

  • Check for hydrocephalus (excess fluid in the brain)

  • Evaluate periventricular leukomalacia (PVL) – brain tissue damage due to lack of oxygen

  • Detect congenital brain malformations

  • Monitor ventricular size in babies with shunts or after surgery

  • Identify infections like meningitis or abscesses

  • Assess brain development in premature infants

👶 Why It Is Mostly Done in Infants

  • In infants, the skull bones are not fully fused, leaving fontanelles (soft spots).

  • These openings act as acoustic windows, allowing sound waves to reach the brain.

  • In older children or adults, ultrasound waves cannot penetrate bone, so MRI or CT is used instead.

🧩 Structures Seen in Cranial Ultrasound

  • Lateral ventricles

  • Third and fourth ventricles

  • Corpus callosum

  • Thalamus and basal ganglia

  • Cerebellum

  • Periventricular white matter

  • Choroid plexus

  • Midline structures

🔍 Procedure

  1. Preparation:

    • No special preparation needed.

    • The baby is usually calm or sleeping during the procedure.

  2. Technique:

    • Conducted using a small transducer (probe).

    • Ultrasound gel is applied over the anterior fontanelle (soft spot on top of the head).

    • The probe is moved gently to capture images from different angles.

  3. Duration:

    • The procedure usually takes 10–20 minutes.

  4. After the Test:

    • The gel is wiped off.

    • The baby can resume normal activities immediately.

📊 Findings (Examples)

Condition Typical USG Finding
Normal Symmetrical ventricles, clear midline, no echogenic areas
Hydrocephalus Enlarged ventricles, dilated lateral horns
IVH (Bleeding) Echogenic material inside ventricles
PVL (Leukomalacia) Increased echogenicity near ventricles
Cysts/Malformations Fluid-filled or abnormal echo patterns

⚠️ Advantages

✅ Safe – no radiation
✅ Painless and quick
✅ Can be repeated often
✅ Ideal for bedside monitoring in neonatal ICUs

🚫 Limitations

❌ Not useful after the fontanelles close (around 1 year of age)
❌ Limited visualization of deep brain structures
❌ Operator-dependent – image quality depends on skill
