Aplasia or hypoplasia of the pancreatic uncinate process: comparison in patients with and patients without intestinal nonrotation.

abstract：:Clinical, angiographic, scintigraphic and pathologic observations in myocardial contusion were correlated. Radionuclide imaging of the injured heart with 99mTc-Sn-polyphosphate provides an accurate diagnosis in acute, even mild, myocardial contusion. The study can be carried out without danger to the critically ill pa...
