Noncontrast CTCT BrainCerebral Venous Sinus Thrombosis Cord SignHyperattenuate SignCVTBackground and Purpose: Increasing concern of cerebral venous thrombosis due to treatable and curable causes of stroke. The diagnosis of cerebral venous sinus thrombosis is challenged due to nonspecific clinical symptomatol...
Non contrast CT scan (a) shows hyperdense lesion with small foci of calcification in the left caudate nucleus and intraventricular hemorrhage (IVH) in posterior horns of lateral ventricles. Coronal (b) and axial (c) cuts of brain CTA shows left caudate nucleus arteriovenous malformation (AVM) w...
CT 平扫(noncontrast CT,NCCT)由于应用广泛、检查时间短、检查费用较低,以及可准确检查蛛网膜下腔出血和脑实质出血等优点,已经成为急性脑卒中的一线影像学检查方法。大量研究证明,NCCT检出急性缺血性脑卒中病灶的能力与MR的T2WI检出能力相当,可以检出6小时内(超急性期)的脑缺血灶。 更重要的是,CT检查不仅能发现超急...

Most patients who have computed tomography because of a suspected brain tumor are subjected to a noncontrast scan followed by a contrast study. Analysis of the scans of all such patients over a two-year period indicates that in most cases a single contrast scan affords the same degree of diag...
Abstract:Hypertensive intracerebral hemorrhage (HICH) is a disease with a rapid onset, rapid progression, high mortality rate, and long-term impact on the ability to function. Non-contrast agent-based CT (NCCT) is a com...
Intrauterine brain damage in nonimmune hydrops fetalis. Nonimmune hydrops fetalis has been described in a large number of pathological conditions, but brain aspect has been poorly explored. We report the neuropa... JC Larroche,MC Aubry,F Narcy - 《Biology of the Neonate》 被引量: 103发表:...
typically less than 3 cm. Approximately 40% to 60% of these lesions demonstrate calcification. They do not demonstrate mass effect, unless there has been recent hemorrhage. It is important to note that the adjacent brain parenchyma appears normal. On contrast-enhanced CT (CECT), cavernomas demon...
