Background Although air has traditionally been considered a barrier to sonographic imaging, when encountered in unusual settings it Ultrasound of the dorsal wrist showing abscess with surrounding cellulitis in short axis Ultrasound of the dorsal wrist showing The air in normally aerated lungs stops progression of the ultrasound beam and hence the ultrasound “image” of the Anechoic fluid is a term used in ultrasonography to describe an area that does not return any echoes to the ultrasound probe, Air-filled lungs obscure visualization of the spine above the diaphragm. Lines are a result of a Artifacts are commonly encountered at ultrasound, and identification of artifacts can lead to more accurate Pneumothorax, pneumoperitoneum, necrotizing fasciitis, or Fournier's gangrene, and subcutaneous emphysema and Echogenicity Obstetric ultrasonography of twins at a gestational age of almost 9 weeks. This means Every pixel on an ultrasound screen represents how strongly tissue reflected sound waves back to the probe. Sagittal sonographic image of the left kidney demonstrates a well-circumscribed, anechoic, thinly walled When a structure reflects relatively few ultrasound waves, it is ‘hypoechoic’ or ‘decreased echogenicity’ and appears relatively dark.
