Hippocampal Microbleed on a Post-Mortem T2∗-Weighted Gradient-Echo 7.0-Tesla Magnetic Resonance Imaging?
نویسندگان
چکیده
The present post-mortem study of a brain from an Alzheimer patient showed on a T(2)∗-weighted gradient-echo 7.0-T MRI of a coronal brain section a hyposignal in the hippocampus, suggesting a microbleed. On the corresponding histological examination, only iron deposits around the granular cellular layer and in blood vessel walls of the hippocampus were observed without evidence of a bleeding. This case report illustrates that the detection of microbleeds on MRI has to be interpreted with caution.

7 Tesla Magnetic Resonance Imaging to Detect Cortical Pathology in Multiple Sclerosis
BACKGROUND Neocortical lesions (NLs) are an important pathological component of multiple sclerosis (MS), but their visualization by magnetic resonance imaging (MRI) remains challenging. OBJECTIVES We aimed at assessing the sensitivity of multi echo gradient echo (ME-GRE) T2*-weighted MRI at 7.0 Tesla in depicting NLs compared to myelin and iron staining. METHODS Samples from two MS patients...
متن کاملDetection of cerebral microbleeds with dual echo T2*-weighted MR imaging at 7.0 Tesla
Introduction Increasing interest in microbleeds had led to an increasing number of studies addressing its prevalence and clinical relevance. Prevalence estimates differ substantially between studies, due to differences in image protocols and field strengths. This study assessed the visualization of cerebral microbleeds with dual echo T2*-weighted imaging at 7.0 Tesla magnetic resonance imaging ...
متن کاملUntangling the R2* contrast in multiple sclerosis: A combined MRI-histology study at 7.0 Tesla
T2*-weighted multi-echo gradient-echo magnetic resonance imaging and its reciprocal R2* are used in brain imaging due to their sensitivity to iron content. In patients with multiple sclerosis who display pathological alterations in iron and myelin contents, the use of R2* may offer a unique way to untangle mechanisms of disease. Coronal slices from 8 brains of deceased multiple sclerosis patien...

متن کاملImaging of articular cartilage: current concepts.
Magnetic resonance imaging (MRI) is the gold standard method for non-invasive assessment of joint cartilage, providing information on the structure, morphology and molecular composition of this tissue. There are certain minimum requirements for a MRI study of cartilage tissue: machines with a high magnetic field (> 1.5 Tesla); the use of surface coils; and the use of T2-weighted, proton density...
