Abnormal regions on MRI and pathology were compared by (a) quantitative measurement of the transmural-extent of the abnormality and (b) picture matching of contours. We found no relationship between the transmural-extent of T2-hyperintense regions and that of the AAR (bright-blood-T2: r=0.06,...
Background: We retrospectively studied the relationship between linear hyperintensity objects (LHOs) on T2-weighted magnetic resonance images (MRI) in the cerebral white matter and the occurrence of hypertensive intracerebral hemorrhage (HIH). Methods: Forty-nine hypertensive patients with a fixed imaging...
diffusion-weighted MRIspreading depressionObjects: Different theories were suggested on the etiopathogenesis of transient global amnesia.Methods: We demonstrate a patient with transient global amnesia, in whom, a transient hyperintense signal change on left hippocampus was detected in diffusion- and T2- ...
SHIVA-CMB: a deep-learning-based robust cerebral microbleed segmentation tool trained on multi-source T2*GRE- and susceptibility-weighted MRI Article Open access 28 December 2024 Artificial intelligence for volumetric measurement of cerebral white matter hyperintensities on thick-slice fluid-attenuated ...
High density on CT of the right striatum turned into normodensity in 4 months, and hyperintensity on T1-weighted MRI and hypointensity on T2-weighted MRI of the lesion were resolved in 18 months. A decreased perfusion of the lesion by SPECT remained 37 months after onset. There was no ...
SWI is an MRI imaging technology that is particularly sensitive to paramagnetic materials. The concentration of paramagnetic deoxyhemoglobin in human venous blood is high, allowing clear delineation of veins on SWI studies. Veins with smooth walls, unobstructed drainage, and high flow rates are clearly...
MRI In the KORA sample, image acquisition was performed on a single 3 T MRI system (Magnetom Skyra; Siemens AG, Healthcare Sector, Erlangen, Germany). WMH volume was assessed on T2w 3D-FLAIR sequences (SPACE, slice thickness (ST): 0.9 mm, 0.5 mm × 0.5 mm in-plane spatial resol...
结果:在MRI,T2加权MRI显示一种放射治疗引起的迟发性广泛性高信号脑损害。这种广泛性脑损害的放射学模式是相当明显的,累及了双侧大脑、小脑、延髓、桥脑、内囊和丘脑。结论:我们的观察表明,放射治疗后患者的脑MRI的迟发性双侧大脑、小脑、延髓、桥脑、内囊和丘脑的高信号损害是一种罕见的放射性迟发性脑病。Back...
