Our analysis in this relatively small patient cohort indicates that (68)Ga-DOTA-TOC PET may be superior to (123)I-MIBG gamma-scintigraphy and even to the reference CT/MRI technique in providing particularly valuable information for pretherapeutic staging of phaeochromocytoma and neuroblastoma.

Dual-energy contrast-enhanced mammography is one of the latest developments in breast care. Imaging with contrast agents in breast cancer was already known from previous magnetic resonance imaging and computed tomography studies. However, high costs, limited availability-or high radiation dose-led to the development of contrast-enhanced spectral mammography (CESM). We reviewed the current literature, present our experience, discuss the advantages and drawbacks of CESM and look at the future of this innovative technique.

IMA may represent a clinical marker for skeletal muscle ischemia, although its lack of specificity requires careful clinical interpretation of data. The short period of IMA elevation after ischemic exercise requires standardized conditions for use as a diagnostic tool and hints at IMA applicability as a marker of prolonged or chronic ischemia.

Pouch formation during RY-BP may be alleviated by simply dissecting the perigastric fatty tissue. In this way the anterior vagal trunk is dissected, however, no influence on clinical, functional and laboratory results occur.

Our study shows that the ischemic condition during constant muscle exercise is clearly characterized by PCr and Pi kinetics, as well as by pH changes. The correlation between the degree of blood flow reduction and PCr levels in the exercising muscle groups, which are supplied by the stenosed arteries, is the first essential of using 31P magnetic resonance spectroscopy in the assessment of the effect of arterial stenoses on muscle function in claudicants.
