This book illustrates the characteristics of imaging after
treatment in brain gliomas. It describes in detail the
modifications to brain tissue, both healthy and pathological, that
can manifest after surgery, radiotherapy or chemotherapy treatment.
These modifications are discussed in terms of both how they occur
in the immediate post-treatment period, and in the long term. The
imaging methods used include CT with and without the addition of
contrast medium, but above all MRI, which involves the use of
routine basic sequences and mainly advanced study techniques such
as diffusion, perfusion, spectroscopy and cortical activation. The
aim of the text is to equip neuroradiologists with adequate
expertise in post-treatment examinations reporting, allowing them
to perform an effective differential diagnosis between the
persistency or recurrence of illness and the effects of short or
long-term treatment. The book is divided into a general section,
which addresses the classification of cerebral tumors, the surgical
treatment options, radiotherapy and chemotherapy protocols; and a
section on clinical cases that employs rich iconography, making it
quick and easy to consult. This second edition has been updated to
reflect the new WHO classification system from 2016; new surgical,
radiotherapy and chemotherapeutic treatment options; and (in the
iconography section) the new sequences available from the
manufacturers of RM scanners.
This book describes the development of systems of magnetic
resonance imaging using the higher magnetic field strength of 3
tesla, in comparison to the current gold standard of 1.5 tesla.
These new systems of MRI make it possible to perform with high
spatial, temporal and contrast resolution not only morphological
examinations but also functional studies on spectroscopy,
diffusion, perfusion, and cortical activation, thus helping
research and providing an important tool for routine diagnostic
activity. At the same time the new systems offer unparalleled
sensitivity and specificity in the numerous conditions of
neuroradiological interest.
This book reviews in detail the role of neuroradiological imaging
in the evaluation of patients who have undergone surgery or
interventional radiology procedures, and particularly its value in
the documentation of normal and pathological post-treatment
changes, detection of complications, and follow-up. The opening
sections describe pretreatment images in various conditions,
including trauma, degenerative disc disease, and osteoporosis, and
the different types of neurosurgical and interventional treatment
that may be used. The post-treatment appearances of normal sequelae
and complications on conventional radiography, CT, and MRI are then
documented in detail on the basis of a large series of clinical
cases, with a wealth of images. Guidance is provided on selection
of one or a combination of imaging modalities. This book will be an
invaluable clinical and research tool not only for
neuroradiologists but also for neurosurgeons, and interventional
radiologists.
