Many different opinions exist as to the appropriate diagnostic workup and therapy for spinal tumors. With the advent of new imaging techniques and therapeutic regimens, an up-to-date reference work has become an urgent requirement. This book is desig
The numerous ways in which man and animals are affected by their physical environment, and the inborn and adaptive responses to change in the'milieu exterieur'have fascinated curious minds since the earliest days of recorded history. Development of t

A number of functional brain imaging studies indicate that the medial temporal lobe system is crucially involved in encoding new information into memory. However, most studies were based on differences in brain activity between encoding of familiar v
MRI is assuming a dominant role in imaging of the larynx. Its superior soft tissue contrast resolution makes it ideal for differentiating invasion of tumors of the larynx from normal or more sharply circumscribed configuration of most of the benign l

With the growing number of MR installations, clinicians and radiologist are being confronted more and more with visual information they do not feel as confident with as with the more'mono-form'infor mation of conventional radiographs, CT and US. Th

Changes in cortical metabolism and cerebral perfusion may be recorded non-invasively with functional magnetic resonance imaging (fMRI). In pilot experiments, using fMRI with photic stimulation, we found differences between activated areas when the le

The purpose of this study was to develop a standardized method of 2D MRA of the proximal 50 mm of the major epicardial coronary arteries. Therefore the efficacy of fixed imaging planes (transverse, coronal, sagittal, 30-degree RAO equivalent, and 60-

Background The clinical significance of anomalously originating coronary arteries depends on their proximal course. Diagnosis of this course by conventional x-ray coronary angiography alone may be equivocal. We postulated that with fast magnetic reso
