ABSTRACT
PURPOSE:
To determine the overall diagnostic accuracy of mononuclear leukocyte- 99mTc scintigraphy in the routine detection of infectious lesions and fever of unknown origin (FUO) in inpatients. MATERIAL ANDMETHODS:
The use of mononuclear leukocyte 99mTc scintigraphy is presented in 87 patients who fulfilled the Durack and Street diagnostic criteria of nosocomial FUO; 66 patients were suspected of having infectious lesions (myocarditis, endocarditis, infected catheters, diabetic foot, and osteomyelitis) and 21 patients presented with unknown causes of FUO. Scans were carried out 1, 3, and 24 h after injection of labeled leukocytes.RESULTS:
In three cases (3/27) where scintigraphs were negative, biopsies were positive. There were two (2/87) false-positive scintigrams. We found a 95.8% sensitivity and 92.3% specificity. PPV was 93.8%, PPN 94.7%, and accuracy 94.2%.CONCLUSION:
Mononuclear leukocyte 99mTc scintigraphy showed high sensitivity, specificity, positive and negative predictive values in patients with nosocomial FUO. These results suggest an important role for nuclear medicine in the management of patients with infection/inflammation.
