The incomplete border sign.
Appearance: Extrapulmonary lesions often show indistinct borders along at least a portion of their margins at chest radiography. This classic sign has been termed the “incomplete border sign.” Explanation: At radiography, visibility of a sharp border depends on (a) a difference in density between a lesion and adjacent structures, and (b) an edge tangent to the x-ray beam.When not directly adjac...
متن کاملClassical eyelid border sign of neurofibromatosis.
Neurofibromatosis is a well-documented entity, having been first recorded by von Reck-linghausen (I882). When involvement of the orbit and eyelid occurs in this disease, the presentation may be manifold. Blepharoptosis commonly occurs and may be variable in degree. Where elephantiasis neuromatosa occurs in association with this, the drooping eyelid characteristically has the sensation of a bag ...
متن کاملBorder-ownership-dependent tilt aftereffect in incomplete figures.
A recent physiological finding of neural coding for border ownership (BO) that defines the direction of a figure with respect to the border has provided a possible basis for figure-ground segregation. To explore the underlying neural mechanisms of BO, we investigated stimulus configurations that activate BO circuitry through psychophysical investigation of the BO-dependent tilt aftereffect (BO-...
متن کاملErythema multiforme as first sign of incomplete Kawasaki disease
Incomplete Kawasaki disease represents a diagnostic challenge for pediatricians. In the absence of classical presentation, the laboratoristic evaluation of systemic inflammation can help in placing the correct diagnosis to promptly start adequate therapy. Erythema multiforme is an acute, self-limiting condition considered to be a hypersensitivity reaction commonly associated with various infect...
متن کاملRestoration of Motion-Blurred Image Based on Border Deformation Detection: A Traffic Sign Restoration Model
Due to the rapid development of motor vehicle Driver Assistance Systems (DAS), the safety problems associated with automatic driving have become a hot issue in Intelligent Transportation. The traffic sign is one of the most important tools used to reinforce traffic rules. However, traffic sign image degradation based on computer vision is unavoidable during the vehicle movement process. In orde...
