Indication for abdominal ultrasound 11
localization of free or loculated peritoneal, pleural or retroperitoneal fluid
Indication for abdominal ultrasound 12

Indication for abdominal ultrasound 13
Evaluation of UTI
Anechoic
Opposite of echogenic, without internal echoes
Echogenic/hyperechoic
opposite of anechoic, echo producing structure
Enhancement
Sound that travels through an anechoic substance and is not attenuated
Fluid-Fluid level
interface between two fluids with different acoustic characteristics; level will change with different patient position
Heterogeneous
not uniform in texture
homogenous
opposite of heterogeneous, completely uniform
hypoechoic
low-level echoes within a structure
Infiltrating
diffuse disease process or metastatic disease
Irrgeular borders
borders are not well defined
Isoechoic
Very close to the normal parenchyma cheogencity pattern
Loculated mass
well-defined borders with internal echoes; septa is thin
Shadowing
sound beam is attenuated by a solid or calcified object
