Aortic aneurysm detected by 99mTc-pyrophosphate imaging: case report. 1977

R J Campeau, and S Gottlieb, and N Kallos

An example of aneurysmal concentration of 99mTc-pyrophosphate (Tc-PPi) is described. An abdominal aortic aneurysm was suspected when a rectilinear bone scan showed an abnormal paraspinal area of activity. The aneurysm was confirmed by ultrasonic examination. Conventional radiographic examination failed to reveal calcification within the aneurysm. Aneurysmal concentration of Tc-PPi should be considered in patients showing abnormal radioactivity in the region of vascular structures on radionuclide bone images.

D011756	Diphosphates	Inorganic salts of phosphoric acid that contain two phosphate groups.	Diphosphate,Pyrophosphate Analog,Pyrophosphates,Pyrophosphate Analogs,Analog, Pyrophosphate
D011877	Radionuclide Imaging	The production of an image obtained by cameras that detect the radioactive emissions of an injected radionuclide as it has distributed differentially throughout tissues in the body. The image obtained from a moving detector is called a scan, while the image obtained from a stationary camera device is called a scintiphotograph.
