    These lines are sharply defined and laser-like and they typically do not fade as they progress down the screen. Churchill Livingstone, New York, Usually scans for this type of detection are done around 18 to 23 weeks of gestational age called the " anatomy scan ", "anomaly scan," or "level 2 ultrasound". The frequencies can be anywhere between 1 and 18 MHzthough frequencies up to 50— megahertz have been used experimentally in a technique known as biomicroscopy in special regions, such as the anterior chamber of the eye. During the second and third trimesters, limited ultrasound evaluation might be needed when a specific question requires investigation.

    The most common is color Doppler or power Doppler, but also other techniques like b-flow are used to show blood flow in an organ.

It might be used to confirm or rule out a congenital heart defect. This imaging modality is used at the bedside to evaluate a number of different lung abnormalities as well as to guide procedures such as thoracentesispleural drainage, needle aspiration biopsy, and catheter placement. Anesthesiology[ edit ] In anesthesiologyultrasound is commonly used to guide the placement of needles when placing local anaesthetic solutions near nerves. However, excessive B-lines are abnormal and are typically indicative of underlying lung pathology.
