Labelling leucocytes with 99Tcm using hexamethylpropyleneamine oxime (HMPAO) utilizes the advantages of technetium over indium in imaging inflammation. A retrospective study has been performed on 43 consecutive patients imaged with 99Tcm HMPAO labelled leucocytes in order to assess the reliability of the technique. Particular attention was paid to the different handling characteristics of the 99Tcm HMPAO labelled cells compared with those labelled with indium. It was found that 99Tcm HMPAO labelled leucocytes gave an overall accuracy of 93.2%, a sensitivity of 92.8%, a specificity of 93.3% and a positive predictive value of 86%. 99Tcm HMPAO labelled leucocyte scanning provides a reliable method of imaging inflammation, though errors in interpretation may occur due to the hepato-biliary excretion of activity that occurs with this technique.

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.

D002675	Child, Preschool	A child between the ages of 2 and 5.	Children, Preschool,Preschool Child,Preschool Children
D003424	Crohn Disease	A chronic transmural inflammation that may involve any part of the DIGESTIVE TRACT from MOUTH to ANUS, mostly found in the ILEUM, the CECUM, and the COLON. In Crohn disease, the inflammation, extending through the intestinal wall from the MUCOSA to the serosa, is characteristically asymmetric and segmental. Epithelioid GRANULOMAS may be seen in some patients.
