Introduction: The aim of this study is to evaluate the diagnostic performance of multidetector CT angiography (CTA) in depicting bronchial and non-bronchial systemic arteries in patients with haemoptysis and to assess whether this modality helps determine the feasibility of angiographic embolisation.
Materials And Methods: Fifty-two patients with haemoptysis between January 2010 and July 2011 underwent both preoperative multidetector CTA and digital subtraction angiography (DSA) imaging. Diagnostic performance of CTA in depicting arteries causing haemoptysis was assessed on a per-patient and a per-artery basis.
Background: Recently a considerable number of promising clinical trials have been designed to perform infusion of stem cells by pancreatic arterial intervention to improve the endocrine function of the pancreas for better diabetes control. It is necessary to investigate the pancreatic body and tail (PBT) arterial system for human islets located mostly in the PBT and identify the predominant artery or arteries. However, the arterial system in the PBT is complicated and variable.

Materials And Methods: The study was approved by the institutional ethics committee; written informed consent was obtained. Forty-two consecutive patients with diabetes received an experimental treatment of autologous bone marrow-derived stem cell transplantation by means of infusion into the dorsal pancreatic artery.
Article Synopsis
- * Results showed that patients had significantly fewer activated regions and lower fractional anisotropy in the occipital lobes before treatment compared to healthy controls, but these measures improved after HBO therapy.
- * The findings indicate that combining BOLD-fMRI and DTI is effective for monitoring changes in visual pathway lesions and their progression during HBO treatment.
Introduction: In recent years, diffusion tensor imaging (DTI) has emerged as a promising tool to study ischemic stroke. The aim of this study is to evaluate the anisotropic changes of cerebral white matter tracks in patients with ischemic stroke using DTI, and investigate the correlation between corticospinal tract damage and muscle strength in such patients during acute ischemia.
Methods: Nine patients with acute ischemic stroke and nine healthy subjects were examined with T1 weighted magnetic resonance imaging (MRI), T2 weighted MRI and DTI.
