Oncology in general has seen vast advancements over recent years. Improved und- standing of tumor biology, multidisciplinary team decisions and an individualized therapy are cornerstones of treatment planning for cancer patients today. These dev- opments have challenged the imaging community with ever more specifc questions on tumor detection, staging and therapy control. Whereas this evolution applies to many tumor entities, rectal cancer takes an outstanding role, as it was the recognition of certain anatomical and pathological features of the disease, with the help of magnetic resonance imaging (MRI), that induced radiology not only to aid in disease mana- ment, but in fact to be a powerful engine for new concepts in rectal cancer treatment. The continuous improvement of highly specialized MRI and the groundbreaking scientifc contributions of radiologists all over the world have paved the way for s- stantial refnements of this technique during the last decade. Consequently, dedicated imaging protocols for routine diagnostic work-up of r- tal cancer patients are now available, which can guide multidisciplinary team de- sions and, in combination with optimized surgery and chemoradiotherapy, lead to longer survival and a better quality of life. Besides the scientifc advances, the enduring clinical success of MRI in the feld of rectal cancer is highly contingent upon expertise. To this end, ongoing education and continuous training are vital.

Das Buch "Bildgebende Diagnostik und operative Therapie bei Lebererkrankungen" stellt systematisch geordnet alle zur Verf}gung stehenden Untersuchungsm|glichkeiten bei Leber- erkrankungen dar. BesondererWert wird darauf gelegt, die Aussagef{higkeit der einzelnen Untersuchungen gegeneinander abzugrenzen und ihre differentialdiagnostische Bedeutung zu erl{utern. Neben der Diagnostik werden f}r jede einzelne Er- krankungauch die M|glichkeiten der chirurgischen Therapie beleuchtet. Dabei wird deutlich, da~ eine zeitgem{~e, ad{quate Diagnostik nicht allein auf der bildgebenden Diagnose, sondern auch auf der Kenntnis m|glicher operativer Therapieverfahren basiert.

AIDS ist die Spätfolge der HIV-Infektion und damit das Endstadium einer Krankheitsentwicklung mit sehr variablem zeitlichen Verlauf und unterschiedlichen klinischen Manifestationen. AIDS-Kranke können zerebrale, pulmonale, kardiale, gastrointestinale und abdominelle Symptome aufweisen, die zunächst - trotz grundsätzlich schlechter Prognose - durchaus einer Therapie zugänglich sind. Der bildgebenden Diagnostik kommt deshalb zur Abklärung der Befunde große Bedeutung zu. Das vorliegende Buch zeigt anhand zahlreicher MRT-, CT-, Ultraschall- und konventioneller Röntgenaufnahmen die typischen AIDS-Manifestationen. Den Befunden bei an AIDS erkrankten Kindern ist ein eigenes Kapitel gewidmet. Damit erhält der Radiologe eine wertvolle Hilfe für die Untersuchungsplanung und die Befundinterpretation.
