The correlation between the echogenicity
of the SN and clinical symptoms in Chinese patients with PDD was also assessed.
The proventricular cross-section usually images as a round structure of medium echogenicity
with hyperechoic contents (ingesta, at times with food particles that produce posterior acoustic shadows).
The internal structure is described by echogenicity
, whereas vascularization is mostly described as hilar, peripheral, or avascular (6-8).
Ultrasound criteria include a diameter greater than 6 mm, concentric rings (target sign), an appendicolith, high echogenicity
, obstruction of the lumen, and fluid surrounding the appendix.
On US, hepatic involvement of amyloidosis has nonspecific findings such as, heterogeneous echogenicity
, diffuse or focal areas of decreased parenchymal attenuation (Fig.
Characteristic ultrasound features of a benign nodule include an oval or flat shape, echogenicity
similar to normal gland parenchyma, a smooth margin, hypoechoic halo around the nodule and peripheral vascularity on color doppler examination1-5.
The other four categories have four choices each, such as "hypoechoic" under the category echogenicity
or "lobulated or irregular" under margin.
Meanwhile, the child underwent a transfontanellar US scan that showed increased echogenicity
of the subcortical white matter and extensive cystic periventricular leukomalacia, well-known findings interpreted as sequelae of HIE.
Due to the suspicious ultrasonographic findings such as echogenicity
at the bladder wall, an abdominal CT was performed.
Transvaginal ultrasound examination revealed uterine enlargement and the endometrial cavity was partially filled with cystic areas of increased echogenicity
and typically showed snowstorm appearance.
Liver parenchymal echogenicity
and biliary ducts on the right lobe were apparently normal.
was increased, echo-pattern was homogenous, no duct dilatation was seen, and the contour was smooth.
