Radiology
Sample Required:
Transcranial Ultrasonography is a non-invasive imaging test that does not require any sample collection beforehand. The test utilizes ultrasound technology to visualize and assess blood flow in the brain’s arteries.
Test Time:
The test time for Transcranial Ultrasonography may vary depending on the complexity of the examination. Typically, the procedure takes around 30 to 60 minutes to complete.
Test Normal Range:
Transcranial Ultrasonography focuses on evaluating the blood flow patterns in the brain’s arteries. The test aims to identify any obstructions, narrowing, or abnormalities in blood flow within the brain.
What is the test?
Transcranial Ultrasonography is a diagnostic imaging test that uses ultrasound technology to obtain real-time images of blood flow in the brain’s arteries. It helps in assessing the cerebral circulation and detecting any potential issues affecting the brain’s blood vessels.
Test Procedure:
During the Transcranial Ultrasonography examination, the patient is usually positioned lying on an examination table. A water-based gel is applied to the scalp over specific areas to aid in sound wave transmission. A handheld transducer with Doppler capabilities is used to obtain images and assess blood flow in the brain’s arteries through the skull.
When to take the test?
Transcranial Ultrasonography is recommended when there is a need to assess blood flow in the brain’s arteries or to investigate conditions such as stroke, aneurysms, or cerebral vasospasm.
Who should take this test?
Individuals with risk factors for cerebrovascular diseases or neurological symptoms such as stroke-like symptoms or transient ischemic attacks (TIAs) should consider Transcranial Ultrasonography.
Precautions for exceptional cases (pregnancy, etc.):
Transcranial Ultrasonography is generally safe for most individuals. However, pregnant individuals should always inform their healthcare providers about their pregnancy status before undergoing any diagnostic imaging tests.
