The standard representation is brighter color for higher echogenicity, giving the almost anechoic fluid an almost black appearance. Echogenicity (sometimes as echogenecity) or echogeneity is the ability to bounce an echo, e.g. return the signal in medical ultrasound examinations. In other words, echogenicity is higher when the surface bouncing ...
Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.
Bronchogenic cysts are usually found in the middle mediastinum. Chest x-rays show a smooth density just in front of the trachea or main stem bronchi at the carinal level. When the cyst communicates with the tracheobronchial tree, the air-fluid level may be seen within the cyst. CT scanning is useful in localizing these cysts.

Congenital pulmonary airway malformation in a fetus, ultrasound at 19 weeks - transverse. Stomach on left image; heart on right image: displaced to right by cystic mass. The earliest point at which a CPAM can be detected is by prenatal ultrasound. The classic description is of an echogenic lung mass that gradually disappears over subsequent ...
Fibrofolliculomas are the most common manifestation, found on the face and upper trunk in over 80% of people with BHD over the age of 40. Pulmonary cysts are equally common (84%) and 24% of people with BHD eventually experience a collapsed lung (spontaneous pneumothorax). Kidney tumors, both cancerous and benign, occur in 14–34% of people ...
Cysts cause posterior enhancement as a consequence of reduced attenuation of the ultrasound within the cyst fluid (Figure 5). The simple cyst is a benign lesion, which does not require further evaluation. [1] Complex cysts can have membranes dividing the fluid-filled center with internal echoes, calcifications or irregular thickened walls.
The ultrasound system converts the strong echogenicity into a contrast-enhanced image of the area of interest, revealing the location of the bound microbubbles. [12] Detection of bound microbubbles may then show that the area of interest is expressing that particular molecular marker, which can be indicative of a certain disease state, or ...
