    Notes: Abstract. Nuclear imaging techniques are well established diagnostic tools in clinical cardiology, providing noninvasive information about myocardial perfusion, function and metabolism. The cost-effectiveness of radionuclide imaging in the diagnostic work-up of patients with coronary artery disease has been demonstrated. Additionally, the documented prognostic value of scintigraphic parameters is of clinical importance to guide decision making. Advances in technology, new radiotracers and new applications contribute to continuous growth in the field of nuclear cardiology. Multi-headed gamma camera systems lead to higher spatial resolution and sensitivity of cardiac single photon emission tomography (SPECT), and they also provide the opportunity for attenuation correction or electrocardiographic gating of SPECT images. Objective quantitative values of perfusion, function and metabolism are derived from scintigraphic data by use of improved software and hardware. With the latest developments in tracer technology, imaging of myocardial necrosis, receptor systems and autonomic innervation has become a reality and will lead to new clinical applications in the future.

    Description / Table of Contents: Zusammenfassung Die Positronenemissionstomographie (PET) stellt die fortschrittlichste szintigraphische Technik zur Beurteilung physiologischer und biochemischer Prozesse invivo im Herzen dar. Die z.Z. verfügbare PET-Technologie erlaubt die Quantifizierung lokaler Tracerkonzentrationen mit hoher räumlicher und zeitlicher Auflösung. Zahlreiche Tracer wurden zur Beurteilung von Perfusion, Substratstoffwechsel sowie autonomer neuronaler Innervation des Herzens entwickelt und werden klinisch eingesetzt. Das bedeutendste klinische Anwendungsgebiet ist die Beurteilung des Substratstoffwechsels mit 18Fluordeoxyglukose (18FDG), die den Gold-Standard für die Vitalitätsdiagnostik bei der koronaren Herzerkrankung (KHK) mit regionaler Wandbewegungsstörung darstellt. Neben der funktionellen Relevanz für die Verbesserung der regionalen Wandfunktion nach Revaskularisation besitzt die 18FDG-PET einen prognostischen Wert hinsichtlich des Nutzen-Risiko-Verhältnisses von Revaskularisationsmaßnahmen. Neuere Untersuchungen weisen darauf hin, daß die 18FDG-PET in kostengünstiger SPECT- oder Koinzidenz-Technik eine vergleichbare klinische Aussagekraft bietet, die bei entsprechender Verfügbarkeit eine breitere Anwendung der Methode erwarten läßt. Die Messung des myokardialen Flusses in Ruhe und unter Belastung mit 13N-Ammoniak oder 82Rb stellt die genaueste szintigraphische Methode zur KHK-Diagnostik und Abschätzung ihres Schweregrades dar. Quantitative Messungen des (regionalen) myokardialen Flusses und die Bestimmung der myokardialen Flußreserve erlauben die Diagnose einer eingeschränkten Vasoreaktivität vor dem Auftreten hämodynamisch wirksamer Veränderungen, aber auch das Monitoring therapeutischer Interventionen (Risikofaktorenmodifikation). Analoga sympathischer Neuronentransmitter wie 11C-Hydroxyepinephrin ermöglichen die Beurteilung der neuronalen (sympathischen) Reinnervation nach Herztransplantation und zeigen eine möglicherweise prognostisch relevante Verminderung der 11C-HED-Aufnahme bei Patienten mit Herzinsuffizienz. Die hohe funktionelle und prognostische Relevanz der PET wird bei besserer Verfügbarkeit und kostengünstigerer Instrumentation den zukünftigen Stellenwert dieser Untersuchungstechnik in Diagnostik, Prognosebeurteilung und Therapiemonitoring bei Herzerkrankungen bestimmen.
    Notes: Summary Positron emission tomography (PET) is currently the most sophisticated scintigraphic imaging technique developed for in-vivo quantification of cardiac physiology and biochemistry. The state-of-the-art PET technology allows delineation of regional tracer activity with high spatial and temporal resolution. A large number of radiopharmaceuticals have been developed to study myocardial perfusion enabling accurate diagnosis and localization of coronary artery disease (CAD) and energy metabolism. More recently, newer tracers such as radiolabeled catecholamine analogues allow the pre- and postsynaptic evaluation of cardiac autonomic innervation. Metabolic imaging with PET represents currently the gold standard for tissue viability assessment with well-validated diagnostic and prognostic information. F-18 deoxyglucose has been also used in combination with SPECT or coincidence imaging providing comparable clinical information but without need for the expensive and rarely available imaging technology of PET. The assessment of coronary flow reserve is the most sensitive scintigraphic method to i) detect vascular abnormalities before their hemodynamic significance, ii) diagnose and define the extent of CAD, and iii) to monitor the effects of (non)pharmacological intervention on regional and global cardiac flow. C-11 hydroxyephedrine (HED) allows imaging of sympathetic neuronal function. The course of cardiac reinnervation after cardiac transplantation was demonstrated with C-11 HED PET, and preliminary evidence suggests that this technique might provide prognostic information on sympathetic neuronal status in congestive heart failure, too. The functional and prognostic relevance of PET imaging together with the increased availability of lower cost instrumentation imaging will define its future role in the diagnosis, assessment of extent, prognosis and in the therapeutic decision making of cardiac disease.

    Description / Table of Contents: Zusammenfassung Örtliche Geschwulstrezidive kündigen in der Regel die ungünstige Verlaufswendung an, weil häufig mit Metastasierung kombiniert. Therapeutische Richtlinien: Zunächst möglichst Bestrahlungsbehandlung, operative Maßnahmen in der Regel erst bei ihrer Erschöpfung bzw. Unmöglichkeit. Beim Tumor-Strahlen-Ulcus palliative ausgedehnte Brustwandresektion unter weiter Indikationsstellung. Defektdeckung nicht durch freie Transplantate, sondern durch Verschiebeplastiken oder heute besser mittels der sog. Netzplastik von Kiricuta.
    Notes: Summary Local recurrences of a tumor generally indicate a poor prognosis, because they are often associated with metastasis. The guidelines for treatment suggested by the author are: radiotherapy should be used first, and surgery as a rule only when radiotherapy has been exhausted or it is not possible. If radiation ulcers occur, extensive palliative resection of the chest wall should be performed. The resulting defect should be covered by means of sliding flaps or Kiricuta sieve grafts rather than direct transfer flaps.
