One of the widespread manifestations cerebral small vessel disease (CSVD) brain parenchyma is white matter lesion, which appears as hyperintensities (WMHs) on magnetic resonance imaging (MRI). Previous studies have illustrated that large artery atherosclerosis related to CSVD, but precise progress pathogenesis remains unknown. High-resolution MRI (HR-MRI) has ability delineate intracranial vascular walls, enabling a thorough exploration structure and composition unstable plaques. This study...

Segmentation of anatomical structures in ultrasound images required radiological technology and a great deal ultrasonic experience. The manual segmentation is often dependent on expertise clinicians time-consuming. Therefore, we present an automatic system for measurement images. We propose scale attention feature pyramid network (SAFNet) fetal biometric measurements from two-dimensional module steered to form at each level. Auxiliary layer used learn object boundary definition with deep...
