Factors associated with cognitive impairment before intracerebral haemorrhage: community-based neuropathological study.

Little is known about whether clinical, radiological or neuropathological features are associated with cognitive impairment before intracerebral haemorrhage. We conducted a community-based cohort study of 125 adults with intracerebral haemorrhage (lobar = 71, non-lobar = 54) with consent to brain autopsy. We compared small vessel disease biomarkers on diagnostic CT head and neuropathological findings including neurofibrillary tangles and amyloid plaques in adults without cognitive impairment versus cognitive impairment without dementia versus dementia before intracerebral haemorrhage, stratified by lobar and non-lobar intracerebral haemorrhage.

Correlations in post-mortem imaging-histopathology studies of sporadic human cerebral small vessel disease: A systematic review.

Aims: Sporadic human cerebral small vessel disease (SVD) commonly causes stroke and dementia but its pathogenesis is poorly understood. There are recognised neuroimaging and histopathological features. However, relatively few studies have examined the relationship between the radiological and pathological correlates of SVD; better correlation would promote greater insight into the underlying biological changes.

A protocol for precise comparisons of small vessel disease lesions between ex vivo magnetic resonance imaging and histopathology.

Rationale: Neuroimaging and clinical studies have defined human sporadic cerebral small vessel disease but the pathophysiology remains relatively poorly understood. To develop effective therapies and preventative strategies, we must better understand the heterogeneity and development of small vessel disease at a cellular level.

Hypothesis: Small vessel disease lesions as seen on neuroimaging have specific neuropathological correlates.

Early Contrast Enhancement: A novel magnetic resonance imaging biomarker of pleural malignancy.

Introduction: Pleural Malignancy (PM) is often occult on subjective radiological assessment. We sought to define a novel, semi-objective Magnetic Resonance Imaging (MRI) biomarker of PM, targeted to increased tumour microvessel density (MVD) and applicable to minimal pleural thickening.

Materials And Methods: 60 consecutive patients with suspected PM underwent contrast-enhanced 3-T MRI then pleural biopsy.
