Gray Level Histogram Width Tissue Characterization

Abstract

Purpose: Proposal to study liver with gray level histogram width (GLHW), clinical ultrasound tissue characterization, using usual B-mode devices. Materials:Placental intervillous space fibrin deposit in fetal growth restriction (FGR), malignant neoplasia, fetal brain, immature fetal lung, meconium-stained amniotic fluid, and healthy adult liver.Methods: Commercial ultrasound B-mode histogram base width divided by full gray scale length was gray level histogram width (GLHW), and it was used to tissue characterization.Results: GLHW of ovarian, cervical and endometrial malignancies were 50 or higher %. Fibrin deposit in placental intervillous space was diagnosed with GLHW and treated with heparin administration to obtain normal neonate. Fetal brain echo density, immature fetal lung, meconium stained amniotic fluid, and healthy adult liver GLHW were studied with GLHW..Helsinki declaration was followed. Conclusion:The GLHW objectively diagnosed ultrasound B-mode image, thus, it would be applied even in adult human cases.
