Investigation of choice for Hydrocephalus in infants ?
Correct Answer: Cranial USG
Description: Brain imaging Imaging tests can help diagnose hydrocephalus and identify underlying causes of the symptoms. These tests may include: Ultrasound. Ultrasound imaging, which uses high-frequency sound waves to produce images, is often used for an initial assessment for infants because it&;s a relatively simple, low-risk procedure. The ultrasound device is placed over the soft spot (fontanel) on the top of a baby&;s head. Ultrasound may also detect hydrocephalus prior to bih when the procedure is used during routine prenatal examinations. Magnetic resonance imaging (MRI) uses radio waves and a magnetic field to produce detailed 3D or cross-sectional images of the brain. This test is painless, but it is noisy and requires lying still. MRI scans can show enlarged ventricles caused by excess cerebrospinal fluid. They may also be used to identify underlying causes of hydrocephalus or other conditions contributing to the symptoms. Children may need mild sedation for some MRI scans. However, some hospitals use a very fast version of MRIthat generally doesn&;t require sedation. Computerized tomography (CT) scan is a specialized X-ray technology that can produce cross-sectional views of the brain. Scanning is painless and quick. But this test also requires lying still, so a child usually receives a mild sedative. Drawbacks to CT scanning include less detailed images than an MRI, and exposure to a small amount of radiation. CT scans for hydrocephalus are usually used only for emergency exams. Reference: GHAI Essential pediatrics, 8th edition
