A 42-year-old female patient presented with acute pain of the upper abdomen, postprandial vomiting and hematemesis. An operation for gastric banding had been carried out 1 month prior to presentation. The abdominal X-ray and radioscopy revealed a posterior slippage of the gastric fundus following the gastric banding operation.

Functional imaging can increase the role of imaging in muscular diseases, as alterations of muscle morphology alone are non-specific for a particular disease. A good example for these functional imaging techniques is to use contrast-enhanced ultrasound (CEUS) to visualize and quantify in vivo (patho-) physiological information about the skeletal muscle microcirculation. Perfusion, i.e. the blood flow per tissue unit including capillary flow, is an important functional parameter. ⋯ Moreover, the arterial perfusion reserve in PAD can be adequately examined using low-mechanical index CEUS. Initial findings have shown that the arterial perfusion reserve in patients suffering from PAD is reduced in comparison to healthy volunteers. In conclusion, modern CEUS techniques can offer deeper insights in muscular (patho-) physiology than just illustrating unspecific myopathic manifestations using conventional diagnostic imaging, such as edematous or lipomatous changes, hypertrophy or atrophy.
