This is the first work to take a comprehensive look at the
application of Magnetic Resonance (MR) techniques in the diagnosis,
follow-up and therapy monitoring of dementing illnesses. The
authors present an overview of MR findings in neurodegenerative and
vascular disorders leading to dementia. In doing so, they also
discuss other diseases that lead to cognitive and/or behavioural
deterioration, such as infectious inflammatory disorders, toxic
encephalopathies, inborn errors of metabolism of adult onset and
post-traumatic, post-radiotherapy and post-chemotherapy conditions.
This authoritative, well-written and richly illustrated reference
work is indispensable for anybody working in the field.
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
lesions. Over ten years ago CT made a major impact on laryngeal
examination because it was the first time that Radiologists were
beginning to look at submucosal disease. All of the previous
examinations duplicated the infor mation that was available to the
clinician via direct and in-direct laryngo scopy. With the advent
of rigid and flexible endoscopes, clinical examination became
sufficiently precise that there was little need to perform studies
such as laryngography which merely showed surface anatomy. The
status of deep structures by these techniques was implied based on
function. Fortunately laryngography is now behind us together with
all of the gagging and contrast reactions which we would all like
to forget. CT is still an excellent method of examining the larynx
but it is unfortunately limited to the axial plane. With presently
available CT techniques motion deteriorates any reformatting in
sagittal or coronal projections. The latter two planes are
extremely helpful in delineating the vertical extent of submucosal
spreads. MRI has proven extremely valuable by producing all three
basic projections, plus superior soft tissue contrast. Although
motion artifacts still degrade the images in some patients, newer
pulsing sequences that permit faster scanning are elimi nating most
of these problems."
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
designed to meet this need, and is the first of its kind to offer
an overview of the opinions of internationally renowned specialists
in the field. By addressing in detail all of the relevant topics
and areas of contention, it should prove of great value in
establishing rational imaging and therapeutic protocols for spinal
tumors.
