Magnetic Resonance Imaging is a very important clinical imaging
tool. It combines different fields of physics and engineering in a
uniquely complex way. MRI is also surprisingly versatile, 'pulse
sequences' can be designed to yield many different types of
contrast. This versatility is unique to MRI. This short book gives
both an in depth account of the methods used for the operation and
construction of modern MRI systems and also the principles of
sequence design and many examples of applications. An important
additional feature of this book is the detailed discussion of the
mathematical principles used in building optimal MRI systems and
for sequence design. The mathematical discussion is very suitable
for undergraduates attending medical physics courses. It is also
more complete than usually found in alternative books for physical
scientists or more clinically orientated works.
This book presents new methods of analyzing and processing
hyperspectral medical images, which can be used in diagnostics, for
example for dermatological images. The algorithms proposed are
fully automatic and the results obtained are fully reproducible.
Their operation was tested on a set of several thousands of
hyperspectral images and they were implemented in Matlab. The
presented source code can be used without licensing restrictions.
This is a valuable resource for computer scientists, bioengineers,
doctoral students, and dermatologists interested in contemporary
analysis methods.

nanoparticles for PET imaging of drug delivery, US nanoparticles
for imaging drug delivery, inorganic nanoparticles for targeted CT
imaging, and quantum dots for optical imaging. This book serves as
a valuable resource for the fundamental science of diagnostic
nanoparticles and their interactions with biological targets,
providing a practical handbook for improved detection of disease
and its clinical implementation.
This text provides a comprehensive review of ERCP and EUS and the
clinical conditions for which they are employed. Presented in a
case-based format with accompanying videos, it will serve as a
valuable practical clinical resource for gastroenterologists with
an interest in ERCP and EUS. The text highlights major techniques
involved in ERCP, reviews complications and recent data on
preventing post-ERCP pancreatitis, and discusses important issues
in training in ERCP including use of endoscopic simulators and
assessment of competency as emphasized in the new ACGME guidelines.
For biliary diseases, new techniques for managing biliary stones,
novel technologies for diagnosing indeterminate biliary strictures,
and new devices for treating benign and malignant strictures are
also highlighted. For pancreatic diseases, advances in minimally
invasive endoscopic techniques for pancreatic stones and
strictures, and management of the complications of pancreatitis are
reviewed. Furthermore, ERCP is not limited by age, pregnancy or
history of abdominal surgeries and special considerations
particular to these patient populations are also discussed. The EUS
chapters review the breadth of equipment available for performing
EUS and EUS-FNA, detail the technique of performing EUS-FNA, and
explore pertinent issues with training and assessing competency
analogous to ERCP training. Valuable insights on the basics of
cytopathology relevant to the endosonographer are summarized. The
classic indication for EUS of staging luminal cancers is examined
in detail while pancreaticobiliary indications are discussed
highlighting newer adjunctive technologies including elastography
and contrast-enhanced EUS. Although in its infancy, the brave new
world of therapeutic EUS is explored with a focus on endoscopic
necrosectomy, EUS-guided biliary and pancreatic access as well as
the exciting possibilities of EUS-guided radiofrequency ablation
and injection of anti-tumor agents. ERCP and EUS: A Case Based
Approach will serve as a very useful resource for physicians who
perform or refer patients for ERCP and EUS. It provides a concise
yet comprehensive summary of the current status of ERCP and EUS
that will help guide patient management and stimulate clinical
research.
Data compiled by the Center for Disease Control and Prevention
indicates an alarming and continuing increase in the prevalence of
autism. Despite intensive research during the last few decades,
autism remains a behavioral defined syndrome wherein diagnostic
criteria lack in construct validity. And, contrary to other
conditions like diabetes and hypertension, there are no biomarkers
for autism. However, new imaging methods are changing the way we
think about autism, bringing us closer to a falsifiable definition
for the condition, identifying affected individuals earlier in
life, and recognizing different subtypes of autism. The imaging
modalities discussed in this book emphasize the power of new
technology to uncover important clues about the condition with the
hope of developing effective interventions. Imaging the Brain in
Autism was created to examine autism from a unique perspective that
would emphasize results from different imaging technologies. These
techniques show brain abnormalities in a significant percentage of
patients, abnormalities that translate into aberrant functioning
and significant clinical symptomatology. It is our hope that this
newfound understanding will make the field work collaborative and
provide a path that minimizes technical impediments.
Neuroimaging Personality, Social Cognition, and Character covers
the science of combining brain imaging with other analytical
techniques for use in understanding cognition, behavior,
consciousness, memory, language, visual perception, emotional
control, and other human attributes. Multidimensional brain imaging
research has led to a greater understanding of character traits
such as honesty, generosity, truthfulness, and foresight previously
unachieved by quantitative mapping. This book summarizes the latest
brain imaging research pertaining to character with structural and
functional human brain imaging in both normal individuals and those
with brain disease or disorder, including psychiatric disorders. By
reviewing and synthesizing the latest structural and functional
brain imaging research related to character, this book situates
itself into the larger framework of cognitive neuroscience,
psychiatric neuroimaging, related fields of research, and a wide
range of academic fields, such as politics, psychology, medicine,
education, law, and religion.
Neuroimaging techniques that can help elucidate and characterize
the nature and mechanism of tissue injury and disease progression
in neurodegenerative disease are of particular importance given its
their roles in seeking successful preventive and therapeutic
treatments. Studying large-scale samples with various disease
mechanisms using multi-parametric imaging, as well as revealing the
correlations between the neuroimaging metrics and clinical data
including neurocognitive function and neuropsychological
inventories to elucidate multiple factors affecting the
neurodegeneration processes in brain are the main topics of this
book. In addition, the neural underpins of cognitive and
psychological functions with advanced functional imaging techniques
can provide better cross-validation and clinical symptom relevance
of multi-parametric data. Expanding the current findings with
higher diagnosis accuracy and detection specificity in multiple
neurodegenerative diseases as well as better differentiation of
each type are the ultimate goal. The results in this book will
extend the current notion of diagnosis value of various relatively
new imaging techniques in multiple neurodegenerative diseases
including traumatic brain injury, post-traumatic stress disorder,
multiple sclerosis and early stage of Alzheimer's disease such as
mild cognitive impairment. Specifically, the neurobiology and
related imaging findings of the four representative
neurodegenerative diseases will be introduced and reviewed,
including brain region-specific and disease-related alterations,
unique clinical symptom of each disease, as well as previous
findings and challenges. There is an increasing body of literature
suggesting that damage to the default mode network, hypothalamus,
thalamus and hippocampus neuronal networks and local injuries might
be under-diagnosed and may account for some of the sequelae
following the neurodegenerative injuries including trauma and
dementia. The relatively novel imaging results to differentiate
each disease using advanced functional connectivity, neuronal
activity, microstructure integrity analysis based on structural
connectivity, multi-dimensional morphometry and molecular imaging
tracers including amyloid and tau for neuropathological burden
quantification were presented to differentiate each type of
disease. We then briefly reviewed some of the therapeutic effects
of traditional Chinese medicine with neuroimaging quantifications
to help treating neurodegenerative diseases. Finally, our work
proves that the multi-parametric neuroimaging methods with more
than twelve metrics and numerous tight clinical association data
presented in this book are the most forefront and up-to-date with
enough sensitivity, precision and resolution. Taken together,
multiple neuroimaging metrics haved been demonstrated in this book
to identify and quantify significant and distinct brain alterations
at function, microstructure, morphology and molecular scales in
different types of neurodegenerative diseases with high sensitivity
and specificity. These comprehensive imaging features could be
combined to improve disease diagnosis accuracy. The aim of this
book is thus intended to provide both beginners and experts in
biomedical imaging and health care a broad and complete picture as
well as the new developments of using multiple metrics in improving
disease identification and diagnosis accuracy. This book would
hopefully capture the interests of colleagues interested in
neurodegenerative disease diagnosis and treatment, and could help
convey the methodological and integrative perspectives of
multi-parametric neuroimaging applications.
