OBJECTIVE: Spinal arteriovenous fístulas (SAVF), a rare type of vascular malformation, account for 3% of all spinal cord lesions. Without early treatment, the associated morbidity is high; furthermore, SAVF pose a major diagnostic challenge. Our purpose was to evaluate the clinical characteristics of SAVF and review their progress after treatment to determine whether it may be too late for treatment in some cases. METHODS: We present a retrospective series of 10 patients diagnosed with SAVF and treated at a tertiary hospital during a 3-year period...

RATIONALE AND OBJECTIVES: Imaging-based assessment of cardiovascular structure and function provides clinically relevant information in smokers. Non-cardiac-gated thoracic computed tomographic (CT) scanning is increasingly leveraged for clinical care and lung cancer screening. We sought to determine if more comprehensive measures of ventricular geometry could be obtained from CT using an atlas-based surface model of the heart. MATERIALS AND METHODS: Subcohorts of 24 subjects with cardiac magnetic resonance imaging (MRI) and 262 subjects with echocardiography were identified from COPDGene, a longitudinal observational study of smokers...

PURPOSE: Recent pulmonary imaging research has revealed that in patients with chronic obstructive pulmonary disease (COPD) and asthma, structural and functional abnormalities are spatially heterogeneous. This novel information may help optimize treatment in individual patients, monitor interventional efficacy and develop new treatments. Moreover, by automating the measurement of regional biomarkers for the 19 different anatomical lung segments, there is an opportunity to embed imaging biomarkers into clinically-acceptable clinical workflows and improve lung disease clinical care...

A chronic expanding hematoma is a hematoma with long term, continuous growth. A 69-year-old male presented with an extra-thoracic chronic expanding hematoma 45 years after thoracoplasty. Six months prior to his visit with us, he had noticed a slight swelling on his back. Three months before his visit with us, the size of the swollen area gradually increased after bowling. Magnetic resonance imaging (MRI) showed an extra-thoracic lesion measuring 120 mm in diameter. Heterogeneous signal intensity on T1- and T2-weighted images inside the lesion was reflected as hematoma of various ages...

: Cerebrospinal fluid (CSF) flux is involved in the pathophysiology of neurodegenerative diseases and cognitive impairment after traumatic brain injury, all hallmarked by the accumulation of cellular metabolic waste. Its effective disposal via various CSF routes has been demonstrated in animal models. In contrast, the CSF dynamics in humans are still poorly understood. Forced Inspiration has recently been identified as a main driving force of CSF flow in the human brain using novel real-time magnetic resonance imaging (MRI)...
