Raphe nuclei echogenicity changes in major depression
Background: Major depression is a common disorder with great social and individual burdens. Transcranial sonography (TCS) is a useful and noninvasive measure for assessment of normal and impaired brain parenchyma. The brainstem raphe nuclei are in close association with dorsocaudal limbic system and plays an important role in depression. In this study we compared the echogenicity of the r...

متن کاملAnalysis of background parenchymal echogenicity on breast ultrasound
The purpose of this study was to analyze the background parenchymal echotexture (BP echo) on breast ultrasound in detail and to evaluate the relation BP echo with menopausal status. In addition, we correlated BP echo with mammographic breast density (MGD) and background parenchymal enhancement (BPE) on magnetic resonance imaging (MRI).The institutional review board of our hospital approved this...
متن کاملQuantification of Ultrasound Contrast Agents Using High Frequency Ultrasound
Ultrasound contrast agents (UCAs) are small microbubbles filled with gas. Because of their scattering properties, UCAs enhance the diagnostic capabilities of ultrasonic imaging. UCAs are associated with therapeutic or enhancing therapeutic applications of ultrasound and with possible adverse bioeffects. Quantification of the in vivo concentration of microbubbles is therefore essential to establ...
