Arthroscintigraphy in suspected rotator cuff rupture.
Nuklearmedizin
January 1999
Department of Nuclear Medicine, Georg August University of Göttingen, Germany.
Aim: In order to evaluate the diagnostic efficiency of arthroscintigraphy in suspected rotator cuff ruptures this new imaging procedure was performed 20 times in 17 patients with clinical signs of a rotator cuff lesion. The scintigraphic results were compared with sonography (n = 20), contrast arthrography (n = 20) and arthroscopy (n = 10) of the shoulder joint.
Methods: After performing a standard bone scintigraphy with intravenous application of 300 MBq 99m-Tc-methylene diphosphonate (MDP) for landmarking of the shoulder region arthroscintigraphy was performed after an intraarticular injection of 99m-Tc microcolloid (ALBU-RES 400 MicroCi/5 ml).
False-positive radionuclide arthroscintigraphy with a porous-coated total hip prosthesis.
Clin Nucl Med
November 1991
Nuclear Medicine Service, Dwight D. Eisenhower Army Medical Center, Augusta, Georgia.
The evaluation of a painful hip prosthesis for suspected loosening frequently requires a multi-modality approach. Radionuclide arthroscintigraphy is a valuable adjunct to contrast arthrography, demonstrating greater sensitivity than contrast arthrography in detecting loosening of the femoral component of the prosthesis. Despite its reliability in the evaluation of cemented hip prostheses, the value of arthroscintigraphy in patients with uncemented or porous-coated prostheses is undetermined.

Scintigraphic and radiographic results correlated exactly in 15 patients, with one false-negative scintigram, one false-positive scintigram, and one false-negative arthrogram. One patient was evaluated by scintigraphy alone.

The range of the mean uptake varied considerably between proximal interphalangeal (PIP) joints in normal subjects. The mean uptake over PIP joints was not significantly different either between normal controls and RA patients, nor between those rheumatoid arthritis patients with and those without clinical signs of inflammation in the PIP joints.
