echogenicity

echogenicity

/echo·ge·nic·i·ty/ (-jĕ-nis´ĭ-te) in ultrasonography, the extent to which a structure gives rise to reflections of ultrasonic waves.

echogenic

(ek″ŏ-jen′ik) [ echo + -genic]
Capable of producing echoes, i.e., of intensely reflecting sound waves rather than transmitting them.
echogenicity (-jĕ-nis′ĭt-ē)

echogenicity

the characteristic ability of a tissue or substance to reflect sound waves and produce echoes. Bone and gas are most echogenic and fluids such as urine and bile the least. Organ parenchyma and soft tissues are intermediate, but each differs slightly from the other and relative characteristics are known.

26) On ultra-sound, these present as a hypoechoic poorly defined solid mass with marked posterior shadowing, though it may also present as a well-circumscribed solid mass with variable echogenicity (Figure 3b).
Minimally decreased echogenicity was noted diffusely, which was surrounded by a minimal hydrocele (Fig.
Abdominal ultrasound (US) reported a small-sized liver (4 cm) with increased paranchymal echogenicity, bilateral hydronephrosis, huge amount of free fluid in abdominopelvic area, and a large pelvic mass with irregular border which US was not able to identify its origin.
Ultrasonographic findings distinguished the mass from the liver and revealed high vascularization of the mass and a moderate increase in echogenicity of the liver.
Amorphous echogenicity, devoid of structural definition of the corticomedullary complex, was present bilaterally.
small kidneys in 10, loss of corticomedullary differentiation in 4, increased echogenicity in 19).
Reduced raphe nuclei echogenicity in patients with suicidal ideation, a negative correlation between impulsivity and SERT binding, reduced 5-HT2A binding in the frontal cortex in patients with a recent suicide attempt, are signs of the serotonergic deficiency in suicidal behavior (17).
Besides the breast and axilla, the ultrasonographic features of lipogranuloma have been described in the penis and scrotum, and have included cases with an ill-defined area of increased echogenicity in the subcutaneous tissue of the penile shaft, (11) a poorly defined extratesticular echogenic mass with an elongated appearance on a longitudinal scan, (1) and an intratesticular heterogeneously hypoechoic mass.
Abdominal ultrasound scan revealed mild hepatomegaly and cortical echogenicity compatible with acute kidney failure.
The ultrasound images (Figures 1 and 2) demonstrate a spindle-shaped soft tissue mass of low central echogenicity, located at the medial margin of the left rectus abdominus muscle.
Contiplex Echo will be available in both open and closed tip (multi-port) configurations along with the Contiplex Tuohy Ultra needle to provide echogenicity from both needle and catheter during CPNB placement.
