Furthermore, they propose guidelines for selection of the appropriate approach based on this new categorization system. METHODS In the midsagittal section of the cervicothoracic MR imaging studies(More)

METHODS The current method to prevent wrong level spine surgery performed is mainly relied on intra-operative X-ray. Unfortunately, because of the unique features and anatomy of the spinal(More)
Fourteen patients with progressive localized tumors were treated on a clinical and pharmacological study with intra-arterial Thiotepa. A transfemoral percutaneous catheter was inserted into the major artery supplying the tumor. A venous catheter was inserted into the vein draining the tumor area for blood sampling. Doses of Thiotepa ranged from 0.3 mg/kg to(More)
