CAMRT Radiography Practice Exam

Which condition is often diagnosed with a prenatal ultrasound?

1. Spina bifida

2. Spondylolisthesis

3. Scoliosis

4. Ankylosing spondylolysis

The correct answer is: Spina bifida

The condition that is often diagnosed with a prenatal ultrasound is spina bifida. This congenital defect occurs when the spinal cord and surrounding structures do not fully close during fetal development. Prenatal ultrasounds are particularly effective in detecting spina bifida because they can visualize the spine and identify any irregularities in its formation. Early diagnosis allows for better planning and management of potential interventions after birth. Spondylolisthesis, scoliosis, and ankylosing spondylolysis are conditions that typically manifest or are diagnosed later in life, often through physical examinations and imaging studies like X-rays or MRI, rather than during the prenatal period. Therefore, while they are important conditions related to the spine, they do not have the same prenatal detection likelihood as spina bifida.
