Bone, vascular smooth muscle, and arachnoid trabeculae are composed of the same type of collagen. However, no studies have investigated the relationship between bone mineral density deterioration and cerebral atrophy, both of which occur in normal, healthy aging. Accordingly, we evaluated whether bone mineral density was associated with brain parenchymal atrophy and ventricular enlargement in healthy individuals. Intracranial cavity, brain parenchyma, and lateral ventricles volumes were measured using brain magnetic resonance imaging (MRI) with a semiautomated tool. We included 267 individuals with no history of dementia or other neurological diseases, who underwent one or more dual-energy X-ray absorptiometry scans and brain MRIs simultaneously (within 3 years of each other) at our hospital over an 11-year period. We found that progression of brain parenchymal atrophy was positively associated with bone mineral density after full adjustment (B, 0.94; P < 0.001). In addition, individuals with osteoporosis showed more parenchymal atrophy among those younger than 80 years. In addition, we observed greater ventricular enlargement in individuals with osteoporosis among those older than 80 years. We believe that osteoporosis may play a role in the acceleration of parenchymal atrophy during the early-stages, and ventricular enlargement in the late-stages, of normal aging-related cerebral atrophy.

Background and Purpose Although preclinical studies have shown inflammation to mediate perihematomal edema (PHE) after intracerebral hemorrhage (ICH), clinical data are lacking. Leukocyte count, often used to gauge serum inflammation, has been correlated with poor outcome, but its relationship with PHE remains unknown. Our aim was to test the hypothesis that leukocyte count is associated with PHE growth. Methods We included patients with ICH admitted to a tertiary-care stroke center between 2011-2015. The primary outcome was absolute PHE growth over 24 hours, calculated using semi-automated planimetry. Linear regression models were constructed to study the relationship between absolute and differential leukocyte counts (monocyte count and neutrophil-lymphocyte ratio [NLR]), and 24-hour PHE growth. Results A total of 153 patients were included. Median hematoma and PHE volumes at baseline were 14.4 (interquartile range [IQR], 6.3-36.3) and 14.0 (IQR, 5.9-27.8), respectively. In linear regression analysis adjusted for demographics and ICH characteristics, absolute leukocyte count was not associated with PHE growth (beta, 0.07, standard error [SE], 0.15, p=0.09). In secondary analyses, NLR was correlated with PHE growth (beta, 0.22; SE, 0.08; p=0.005). Conclusions Higher NLR is independently associated with PHE growth. This suggests that PHE growth can be predicted using differential leukocyte counts on admission.

Though the modern medical imaging research is advancing at a booming rate, it is still a very challenging task to detect brain tumor perfectly. Medical imaging unlike other imaging system has highest penalty for a minimal error. So, the detection of tumor should be accurate to minimize the error. Past researchers used biopsy to detect the tumor tissue from the other soft tissues in the brain which is time-consuming and may have errors. We outlined a two-stage verification-based tumor segmentation that makes the detection more accurate. We segmented the tumor area from the MR image and then used another algorithm to match the segmented portion with the ground truth image. We named this new algorithm as watershed-matching algorithm. The most promising part of our model is the status checking of the tumor by finding the area of the tumor. Our proposed model works better than other state-of-the art works on BRATS 2017 dataset.
