Abstract

Aim

Clinical ultrasound tissue characterization, using usual B-mode devices.

Materials and methods

Malignant neoplasia in ovary, uterine cervix, and endometrium; placental intervillous space fibrin deposit; fetal growth restriction; fetal brain, fetal lung immaturity; meconium-stained amniotic fluid and healthy adult liver; Tissue was characterized by gray-level histogram width (GLHW) divided by full gray scale length.

Results

Malignant GLHW was higher than in benign one (it was malignant if the GLHW was 50% or more in ovary, uterine cervix, and endometrium). The GLHW of placental fibrin deposit was higher than normal placenta. It was reduced by heparin and normal neonate was obtained. Fetal brain echo density, immature fetal lung, and meconium-stained amniotic fluid were diagnosed by GLHW, and normal adult liver GLHW was studied. Helsinki declaration was followed.

Conclusion

The GLHW tissue characterization objectively diagnosed ultrasound B-mode image in obstetrics and gynecology; thus, it would also be applied in common adult human cases.
