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 ...
There is a great difference in echogenicity between the gas in the microbubbles and the soft tissue surroundings of the body. Thus, ultrasonic imaging using microbubble contrast agents enhances the ultrasound backscatter , (reflection) of the ultrasound waves, to produce a sonogram with increased contrast due to the high echogenicity difference.

Common findings on liver doppler ultrasound include increased phasicity of portal veins with eventual development of portal flow reversal. The liver is usually enlarged but maintained normal echogenicity. A liver biopsy is required for a definitive diagnosis. [citation needed]
The journal Nucleic Acids Research regularly publishes special issues on biological databases and has a list of such databases. The 2018 issue has a list of about 180 such databases and updates to previously described databases. [2]
The sonographic features of testicular appendiceal torsion include a circular mass with variable echogenicity located adjacent to the testis or epididymis [Fig. 30], reactive hydrocele and skin thickening of the scrotum is common, increased peripheral vascular flow may be found around the testicular appendage on color Doppler ultrasound.
Decline in average human body temperature since the 19th century: Medical data suggests that the average body temperature has declined 0.6 °C since the 19th century. The cause is unclear although it has been suggested that it has some relation with reduced inflammation from reduced exposure to microorganisms.
The epididymis (/ ɛ p ɪ ˈ d ɪ d ɪ m ɪ s /; pl.: epididymides / ɛ p ɪ d ɪ ˈ d ɪ m ə d iː z / or / ɛ p ɪ ˈ d ɪ d ə m ɪ d iː z /) is an elongated tubular genital organ attached to the posterior side of each one of the two male reproductive glands, the testicles.
