Molar pregnancy: early diagnosis by ultrasound.

This report reviews four cases with vaginal bleeding and early ultrasound diagnosis of abnormal pregnancy before nine weeks gestation, who were followed by serial ultrasound examinations and subsequently diagnosed as hydatidiform mole. The findings support the view that hydatidiform mole may arise from a blighted ovum. It is concluded that vaginal bleeding in the first trimester should be investigated by diagnostic ultrasound, and the pregnancy by terminated if an abnormal development has been confirmed.

Echogenic fluid: a pitfall in the ultrasonographic diagnosis of cystic lesions.

Although it is well known that biliary sludge can produce fine diffuse echoes within the gallbladder, it is less commonly appreciated that other cystic structures may contain echogenic fluid and therefore be mistaken sonographically for solid lesions. In this article three cases of splenic cysts and one case each of pyrometrocolpos, hydroureter, and pyonephrosis presented with diffuse fine echoes in the fluid. Three of these cases were misinterpreted as a result of this echogenic appearance. These cases serve to emphasize the need for awareness of the echogenicity of some types of fluid and the value of other signs of cystic lesions besides absence of internal echoes.

Ultrasonic backscatter from human liver tissue: its dependence on frequency and protein/lipid composition.

Ultrasonic volume backscatter by postmortem human liver was investigated in the 1 to 5 MHz frequency range. Representative values of the backscatter coefficient, its range, and frequency dependence were determined. The backscatter level correlated significantly with protein content in normal livers and with lipid content in abnormal fatty livers. The latter suggests the possible development of a simple, noninvasive, quantitative test for fatty infiltration of the liver.

Nephrosonography in infants and children: a new technique.

A technique has been developed for the ultrasonic investigation of renal disease in infants using a specially designed water-bath with a conventional ultrasonic scanner. This permits ultrasonic studies of the renal tract from the neonatal period onwards; the procedure does not distress the child and the water acts as an excellent coupling medium.
