Multiple advanced neuroimaging applications in various neurodegenerative diseases including Parkinson's disease (PD), frontotemporal dementia (FTD), vascular dementia (VaD) and autism spectrum disorder (ASD) are covered in this book. Relatively novel techniques such as integrated PET/MRI and independent component analysis (ICA)-based dual regression (DR) methods were developed to capture multi-level molecular/functional and structural/microstructural as well as high-order inter-network coordination abnormalities. For instance, both PET dopamine transporter and striatal binding ratio reductions in the caudate and putamen were found in PD, consistent with the diffusion tensor imaging (DTI) fractional anisotropy (FA) reduction and fMRI voxel-mirrored homotopic correlation (VMHC) in the substantia nigra (swallow tail sign signature of PD). Furthermore, dopamine storage and pathway labeled with the vesicular monoamine transporter tracer identified decreased densities in the bilateral mesial temporal cortex, caudate, orbitofrontal cortex, left frontal and occipital cortices, consistent with the morphological atrophy, functional connectivity and conductivity deficits in PD. Similarly in FTD patients, the advanced MRI methods such as ICA-DR, VMHC, voxel-based morphometry (VBM) as well as PET tracer for amyloid accumulation and FDG glucose uptake identified typical brain atrophy, structural dis-connectivity, glucose hypometabolism, higher neuropathological burden, lower interhemispheric correlation as well as disrupted intra- and inter-network modulation in the orbitofrontal and anterior temporal cortices together with insular and frontoparietal networks, with the cerebellum and dorsolateral attentional network as typical compensations. Functional and structural abnormalities had further been elucidated in the VaD dependent participants and autistic children. For instance, both lower FA and VMHC, brain atrophy and functional connectivity deficits, demyelination, axonal degeneration and white matter integrity damage in several white matter tracts were present in the dependent compared to independent participants in VaD data cohort. Increased neuronal activity with higher global fractional amplitude of low frequency fluctuation (fALFF) in the conventional and slow-wave sub-band was confirmed with less efficiency of systematic integration in VaD dependent group. Moreover, in ASD compared to controls, regional gray matter volume and cortical thickness in all four brain lobes increased, whereas white matter volume were decreased in addition to the lower temporal, visual and superior frontal but higher inferior and dorsolateral prefrontal cortical functional connectivities exhibited in ASD. The differences in each type of disease could also be revealed with the same imaging method based on either unique region or distinct brain circuit inter-connection, using VMHC, ICA-DR, DTI, VBM, fALFF and graph-theory based small-worldness analysis. In this book, we have developed and generalized conventional and advanced imaging methodologies to several common neurodegenerative diseases. For instance, we have identified the unique imaging signature for each disease type and the underlying neuropathological mechanism connections with conductivity, structural and microstructural connectivity, intra- and inter-network correlation, systematic integration and efficiency analyses. Our objective, comprehensive and confirmative results indicated great potential in utilizing these quantifications for accurate disease classification and staging. With solid imaging evidence, thorough analysis and generalized applications, this book should capture the interests of readers in the broad fields of brain science, disease diagnosis and effective treatment.

Pattern recognition is an important learning tool in the interpretation of ECGs. Unfortunately, until faced with a patient with an arrhythmia or structural heart disease, pediatric practitioners generally receive limited exposure to ECGs. The ability to clearly distinguish an abnormal ECG pattern from a normal variant in an emergency situation is an essential skill, but one that many pediatricians feel ill-prepared to utilize confidently. In "Pediatric ECG Interpretation: An Illustrative Guide," Drs. Deal, Johnsrude and Buck aim to address this issue by illustrating many of the ECG patterns a pediatric practitioner is likely to encounter.

ECG illustrations with interpretations are presented in several categories: normal children of all ages, acquired abnormalities such as hypertrophy or electrolyte disorders, and common congenital heart disease lesions. Later sections cover bradycardia, supraventricular and ventricular arrhythmias, and a basic section on pacemaker ECGs. Simple techniques used to interpret mechanisms of arrhythmias are described as a resource for practitioners in cardiology, adult electrophysiology, or pediatrics who may not have a readily accessible resource for these ECG examples.

The accompanying CD has been prepared with 3 purposes in mind:
1 as a self-evaluation tool for interpretation of ECGs
2 as a teaching reference for Cardiology fellows, residents, and house staff
3 as an invaluable resource for the Emergency Room physician or pediatrician who might obtain an ECG on a pediatric patient

In unserem Schrifhum hat es bisher an einer praktischen Einfiihrung in die Technik und Befundung der Mammographie gefehlt, die den radiologisch tiitigen Arzt in die Lage versetzt, dieses interessante und wichtige Gebiet der Rontgen- diagnostik in systematischer Weise anzugehen und auf dieser Basis weitere eigene Erfahrungen zu sammeln. Eine moglichst einfache, aber exakte Klassifizierung der Befunde soll vor allem der Verstandigung innerhalb der radiologisch tatigen Arzte dienen und dariiber hinaus spaterhin eine gemeinsame statistische Auswertung erlauben. Erfreulicherweise wird das von Herrn Oberarzt Dr. SEIFERT ausgearbei- tete Schema jetzt bereits von vielen praktisch tatigen Radiologen und einer groBeren Zahl von Krankenhausern angewandt. Die personlichen Erfahrungen von Herrn Oberarzt Dr. SEIFERT griinden sich auf fast 16000 Mammographien, das diesem Buch zugrundeliegende Bildmaterial stammt aus der Auswertung von 8 000 Fallen. In bisher 23 Fortbildungsveranstaltungen konnte Herr Oberarzt Dr. SEIFERT in didaktischer Hinsicht die Erfahrungen erwerben, die ihren Niederschlag in diesem Buch gefunden haben. Er hat sich mit dem vorliegenden kleinen Lehrbuch ohne Zweifel ein groBes personliches Verdienst erworben, und es ist mir eine besondere Freude, daB diese Arbeit in der von mir geleiteten Strahlenklinik des Klinikum Essen entstehen konnte. Somit darf ich dem Buch eine weite Verbreitung unter den radiologisch tatigen Arzten wiinschen und vor allem die Hoffnung aussprechen, daB sein Beitrag zur Verbesserung der Friihdiagnose des weiblichen Brustkrebses und damit zur Anhebung unserer Heilungsziffern fiihren wird.

Die Wirkung ionisierender Strahlen im Niedrigdosenbereich mit den moglichen Risiken von Spatschaden wird derzeit noch kontrovers diskutiert. Verschiedene Ansatze und Studien zu diesem Problemkreis wurden von Experten unterschiedlicher Fachrichtungen - der Strahlenbiologie, Nuklearmedizin und Physik - im Laufe des Symposiums vorgestellt. Die Diskussion betraf vor allem genetische Schaden, die sich auf Grund tierexperimenteller Daten belegen lassen sowie Untersuchungen zu kanzerogenen und teratogenen Effekten von Niedrigstdosisstrahlen, vor allem durch naturliche Grundstrahlung oder durch Exponierung in der Strahlenmedizin. Von besonderem Interesse sind die Ergebnisse der Neubewertung des Strahlenkrebsrisikos von Uberlebenden der Atombombenexplosionen in Japan. Messungen und Beurteilungen der Gesundheitsrisiken im Zusammenhang mit der Reaktorkatastrophe von Tschernobyl bilden die Grundlage fur weitere Diskussionen uber Gefahren und Nutzen der Kernenergie.

Die Dysphagie als interdisziplinares Problem hat bisher aufgrund der fachimmanenten Uberschneidungen keine systematische Aufarbeitung erfahren. Die in diesem Buch dargestellten Methoden erlauben eine Differentialdiagnose und Differentialtherapie von Dysphagie, Globus pharyngis und insbesondere der Aspirationspneumonie, welche im Rahmen der Bevolkerungsuberalterung zunehmend an Bedeutung gewinnt. In einfuhrenden Kapiteln werden Anatomie und Physiologie des Schluckvorgangs detailliert dargestellt. In den folgenden Kapiteln werden gutartige Funktionsstorungen und bisher nur schwer erfassbare morphologische Storungen im Rahmen eines Konzeptes der pharyngo-osophagealen Interaktion vorgestellt. Es werden Symptomkomplexe vom Globus pharyngis uber die "benigne" Dysphagie bis zum schwer neurologisch erkrankten Patienten mit Aspiration abgehandelt und eine detaillierte Differentialdiagnose und, soweit moglich, Differentialtherapie aufgezeigt. Anatomische Abbildungen sowie Flow-Schemata und praxisgerechte Untersuchungsschemata erlauben dem Radiologen eine rasche Erfassung und ein schnelles Erlernen der Methodik. Eine Fulle von hochwertigen Rontgenaufnahmen und Schemazeichnungen geben dem Buch den Charakter eines Lehratlas.
