SECTION I: ANATOMY AND PHYSIOLOGY
### Domain Weight: 26% (Approximately 43 Questions)
**Question 1.** A sonographer is performing a neonatal head ultrasound on a 32-week
premature infant. Which of the following structures is BEST visualized through the anterior
fontanelle?
A. Posterior fossa structures
B. The entire ventricular system
C. The spinal cord
D. The optic nerve
**CorreCt Answer: B**
**Rationale:** The anterior fontanelle serves as the primary acoustic window for
neonatal neurosonography, allowing comprehensive evaluation of the neonatal brain, including
the entire ventricular system, germinal matrix, and intracranial structures.While the posterior
fontanelle can provide supplementary views of the posterior fossa, the anterior fontanelle
remains the optimal window for visualizing the ventricular system. The spinal cord and optic
nerve require separate acoustic windows and transducers.

**Question 2.** Which cranial bone has a characteristic "batwing" shape on neonatal cranial
ultrasound?
A. Frontal bone
B. Parietal bone
,Page 3 of 142
C. Sphenoid bone
D. Occipital bone
**CorreCt Answer: C**
**Rationale:** The sphenoid bone is characteristically described as having a "batwing"
shape on neonatal cranial ultrasound. This knowledge is essential for identifying normal cranial
anatomy and distinguishing it from pathological findings. The frontal, parietal, and occipital
bones have different characteristic shapes and positions within the neonatal skull.
---
**Question 3.** A 1-day-old neonate is being evaluated for hydrocephalus. The anterior
fontanelle is used as the acoustic window. Which anatomical structure is the sonographer
primarily evaluating through this approach?
A. The neonatal spine
B. The neonatal brain
C. The neonatal hip joint
D. The neonatal kidney
**CorreCt Answer: B**
**Rationale:** The anterior fontanelle serves as the primary acoustic window for
neonatal neurosonography, allowing evaluation of the neonatal brain. This approach permits
visualization of intracranial structures including the ventricles, germinal matrix, and brain
parenchyma.The neonatal spine, hip joint, and kidney are evaluated through different acoustic
windows and transducer positions.

**Question 4.** Which of the following is the most common location of germinal matrix
hemorrhage in a preterm infant?
A. Caudothalamic groove
B. Posterior fossa
C. Subarachnoid space
D. Periventricular white matter
**CorreCt Answer: A**
**Rationale:** The germinal matrix is located in the caudothalamic groove, which is the
most common site for germinal matrix hemorrhage in preterm infants. This highly vascular
region is particularly vulnerable in premature neonates due to immature autoregulation of
cerebral blood flow. Posterior fossa hemorrhage, subarachnoid hemorrhage, and periventricular
leukomalacia are distinct entities with different locations and clinical implications.
---
**Question 5.** Which of the following best describes the normal sonographic appearance of
the neonatal thymus?
A. Hyperechoic with multiple calcifications
B. Hypoechoic with a thin echogenic capsule
C. Anechoic with posterior acoustic enhancement
D. Heterogeneous with coarse echotexture
**CorreCt Answer: B**
