Key result
Radionuclide imaging with 99m-Tc-Sn-polyphosphate or pyrophosphate successfully visualized the injured myocardium as an abnormal area of increased activity in 8 patients with myocardial contusion.
Why the study?
Does radionuclide imaging with 99m-Tc-Sn-polyphosphate or pyrophosphate diagnose myocardial contusion in patients with closed chest injuries?
Observational (n=8)
Does radionuclide imaging with 99m-Tc-Sn-polyphosphate or pyrophosphate diagnose myocardial contusion in patients with closed chest injuries?
Radionuclide imaging with 99m-Tc-Sn-polyphosphate or pyrophosphate may provide a specific and confirmatory diagnosis of myocardial contusion in patients with closed chest injuries.
May support scintigraphic diagnosis in closed-chest trauma; hypothesis-generating and should not change practice without validation.
A new method of diagnosing myocardial contusion was studied in 8 patients in whom the injured mycardium was visualized as an abnormal area of increased activity in the region of the heart one hour after intravenous injection of 10 mCi of 99m-Tc-Sn-polyphosphate or pyrophosphate. Serum enzymes in these patients were elevated, but electrocardiograms were nonspecific for myocardial injury. It is hoped that this new technique of imaging the injured myocardium will provide specific and confirmatory diagnosis of myocardial contusion associated with closed chest injuries.
