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.

“…All 3D T1-weighted MPR MR images (slice thicknesses, 1.5–3.0 mm) were obtained using the Ingenia 3.0 Tesla CX (Philips Ingenia, Philips Medical Systems, Böblingen, Germany) and Achieva 3.0 Tesla TX (Philips Achieva, Philips Medical Systems, Böblingen, Germany) scanners at our hospital. A previous study described that MPR sequences with a 3.0 Tesla MRI provided excellent visualization for the inner structures of the head and brain [12].…”

PurposeOsteoporotic vertebral compression fractures (OVCFs) have a serious impact on people’s health and quality of life. The purpose of this study was to analyze brain volume in patients with osteoporosis using brain magnetic resonance imaging (MRI) and to investigate the relationship with osteoporotic vertebral compression fractures.Materials and methodsWe included 246 patients with osteoporosis who underwent thoracolumbar radiographs and brain MRI at our hospital. Clinical data on age, sex, bone mineral density, height, weight, osteoporosis medication, hypertension, diabetes, alcohol drinking, and smoking were collected. Intracranial cavity, brain parenchyma, and lateral ventricles volumes were measured using brain MRI with a semiautomated tool.ResultsWe founded an independent correlation between age and volume percentages of the brain parenchyma and lateral ventricles. We observed a statistically significant decrease in volume percentage of the brain parenchyma and an increase in volume percentage of the lateral ventricles with increasing age. In addition, we confirmed that patients with OVCF showed a significantly lower volume percentage of brain parenchyma than patients without OVCF.ConclusionWe observed a significant association between OVCF and volume percentage of brain parenchyma. Degeneration of the brain may lead to a high incidence of falls, and OVCF may occur more frequently in patients with osteoporosis.

Bu çalışmanın amacı köpek beyninin 3 boyutlu anatomisinin 3 tesla manyetik rezonans tarama görüntülerinin multiplanar rekonstruksiyonu aracılığıyla in situ olarak gösterilmesidir. Neurocranial yapıların anatomik detaylarının gösterilmesi için 9 adet yetişkin mesaticephalic ırk köpek kullanıldı. Bu amaçla T1 ve T2-ağırlıklı space sekans taramalarının üç boyutlu yeniden şekillendirilmiş görüntülerinden yararlanıldı. 3D-IR-MPR sekansı ile alınan görüntüler, baş ve beyine ait derin yapıların ayrıntılı olarak görüntülenmesini sağladı.
