What is Neurosonography?
Ultrasound imaging (sonography) is a diagnostic procedure that uses high-frequency sound waves to produce images of the internal structures of your body. The sound waves are produced by a device called a transducer. As they pass through your body they produce echoes, which are captured to create real-time images that can be observed on a computer screen and interpreted by your doctor. It is used to monitor the development of an unborn child during pregnancy, to diagnose different conditions and also guide certain instruments during surgery.
Neurosonography, also called neuroimaging, is the imaging of the nervous system (brain, spinal cord, and nerves) and works on the same principle as ultrasound. It studies blood flow to different parts of the nervous system, diagnosing conditions such as artery blockage, hemorrhage, aneurysms, tumors, and other neurological abnormalities. Neonatal neurosonography is used to study the nervous system of premature infants for disorders or defects such as sickle cell anemia, which is associated with a high risk of stroke. The imaging technique has also been used to precisely locate and destroy lesions causing essential tremor (involuntary rhythmic shaking).
One of the common techniques used in neurosonography is transcranial Doppler ultrasound which is non-invasive and portable.
