Application of fiber tractography and diffusion tensor imaging to evaluate spinal cord diseases in dogs
Fiber tractography is a technique capable of depicting the three-dimensional structure and connectivity of nerve fibers using serial magnetic resonance diffusion tensor imaging (DTI). To establish fiber tractography and DTI methods in veterinary clinical medicine, we evaluated fiber tractography and DTI parameters: apparent diffusion coefficient (ADC) values and fractional anisotropy (FA) value...
متن کاملDiffusion tensor imaging in spinal cord injury
BACKGROUND AND PURPOSE To assess the feasibility of spinal tractography in patients of spinal cord injury vs a control group and to compare fractional anisotropy (FA) values between the groups. MATERIALS AND METHODS Diffusion tensor imaging (DTI) was performed in the spinal cord of 29 patients (18 patients and 11 controls). DTI was done in the cervical region if the cord injury was at the dor...

Carcinoma of Bronchus-Garnett et al. MEDICALIJSUHNAL the explanation for the absent lobar perfusion in the other four patients in group 1. However, it is also possible that the bronchial tumour was producing obstructive emphysema, in which case it is postulated that the intra-alveolar pressure may then have been sufficient to prevent the radioactively labelled microemboli from entering the emph...
متن کاملPalliative CT-Guided Cordotomy for Medically Intractable Pain in Patients with Cancer.
Palliative cervical cordotomy can be performed via percutaneous radiofrequency ablation of the lateral C1-2 spinothalamic tract. This rare procedure can be safe, effective, and advantageous in mitigating medically intractable unilateral extremity pain for selected patients with end-stage cancer. This report reviews the indications, techniques, risks, and potential benefits of cordotomy. We desc...
متن کاملCT-Guided High-Level Percutaneous Cervical Cordotomy for Intractable Cancer Pain.
AIM To evaluate the safety and effectiveness of computed tomography-guided high-level percutaneous selective cervical cordotomy (CT-guided HPSCC). MATERIAL AND METHODS CT-guided percutaneous procedures were performed in fifty-nine patients between the years 2004- 2013 for cancer pain. Forty-eight patients with cancer-related body pain were treated with CT-guided HPSCC was evaluated retrospect...
