Juan M. Taveras, MD, Professor Emeritus at the Harvard Medical School and Radiologist-in-Chief Emeritus of the Massachusetts General Hospital, died in his native Dominican Republic on March 28, 2002. His death marks the passing of a dominant force in the establishment and advancement of the specialty of neuroradiology. His landmark innovations in training, investigation, radiologic administrati...

The President of the American Society of Neuroradiology (ASNR), Derek Harwood-Nash, asked me as founder of the Society to write an essay on the occasion of its 25th anniversary. I am extremely happy and highly honored to respond to this request but wonder if I can do justice to such an important occasion . The founding of the ASNR in 1962 was an important step in the development of neuroradiolo...

Anaesthesia is required for neuroradiological diagnostic procedures such as angiograms, computerized tomography (CT), and magnetic resonance imaging (MRI) or for therapeutic intervention (Table 1). Interventional neurovascular procedures are part of a trend towards minimally invasive neurosurgery, an important development in which has been the introduction of the Guglielmi detachable coil (GDC)...

The year 2002 in therapeutic neuroradiology has been dominated by the publication of the International Subarachnoid Aneurysm Trial (ISAT), which has already generated considerable debate among those who treat cerebral aneurysms. Although less dramatic, advances have also occurred in the areas of extracranial and intracranial angioplasty/stenting, endovascular stroke therapy, and cerebral arteri...

M ANY recent developments in technology have resulted in great progress in the investigation and treatment of patients with central nervous system diseases by radiological procedures. Anaesthetists may be involved in the care of these patients when the procedures are prolonged or uncomfortable, require complete immobility of the patient, or when the patient does not tolerate the procedure witho...

In 2008 we witnessed a rapid advancement in stent technology, which is reflected in the high number of case reports, publications of case series, and randomized trials. Stents not only served for a combined intrasaccular and extrasaccular treatment of challenging aneurysms but also assisted the revascularization in acute and chronic ischemic conditions of the neurovascular system. Although a se...

Neuroendovascular therapy has grown rapidly in the past few years owing to the addition of new catheters, new embolic agents, and an increasing interest by both neuroradiologists and other clinical specialists. The growth in this area can be seen in the increasing number of presentations in the interventional section at the annual meeting of the American Society of Neuroradiology. From 1987 to ...

~n the evaluation of a developing organ system, it ts a challenge to recognize the continuously changing state of normal, identify variations of normal, appreciate abnormalities, and assess their significance. So it is in pediatric neuroradiology (1~, exemplified by the trite, often overused aphonsm-a child is not simply a small adult. The very complexity of the developing central nervous syste...
