👉 Screening fluid, also known as wash fluid or wash solution, is a critical component in medical imaging procedures, particularly in ultrasound. It serves to dampen the acoustic impedance between the transducer and the patient's skin, thereby reducing reflections at the interface and improving image quality. This fluid is typically a saline-based solution with added detergents and stabilizers to ensure it remains stable and non-toxic during use. The screening fluid is applied to the skin in a thin layer, usually at the site of interest, and is absorbed or drained after the imaging session to minimize patient discomfort and ensure safety.
