Here, we present the case of an extremely subtle peripheral graft infection caused by Staphylococcus aureus. The lack of local signs and the negativity of all imaging studies, including (99m)Tc-HMPAO-Labelled-Leukocyte Scan which is reported to have 100% sensitivity, delayed the diagnosis and therapy, which were both provided by surgery.

OBJECTIVES To explore the use of 99technetiumm-hexamethyl propylene amine oxime single photon computed tomography (HMPAO-SPECT) of the brain as a means of detecting nervous tissue damage in divers and to determine if there is any correlation between brain image and a diver's history of diving or decompression illness (DCI). METHODS 28 commercial divers with a history of DCI, 26 divers with no...

Leukocyte activation is a property of systemic infection. In a previous animal experiment we could demonstrate, that granulocytes, which were already activated by the immune system, were more useful in the evaluation of scintigraphic imaging infection than non activated donor granulocytes. The purpose of the present study was to investigate the in vitro activation of isolated polymorphonuclear ...

PURPOSE Neuronal ceroid-lipofuscinoses (NCL) are among the progressive encephalopathies of childhood that are inherited in an autosomal recessive manner. In this study we specifically aimed to investigate any white-matter changes in the carriers (parents) and the healthy siblings of individuals with neuronal ceroid lipofuscinosis disease and whether we may be able to predict the occurrence of a...

BACKGROUND AND PURPOSE Measuring blood pressure (stump pressure) in the distal internal carotid artery during occlusion of the internal carotid artery is reportedly a reliable safety index with which to predict ischemia following permanent occlusion of the internal carotid artery. We compared the stump pressure during occlusion of the internal carotid artery with single-photon emission CT (SPEC...

brain single-photon emission computerized tomography (spect), in particular, with perfusion agents or with neuroreceptor imaging radiopharmaceuticals, is rapidly becoming a clinical tool in many neurologic and psychiatric conditions. this imaging modality has been used for diagnosis, prognosis assessment, evaluation of response to therapy, risk stratification, detection of benign vs. malignant ...

We separated platelets from whole blood and incorporated them into In-Ill and Te-99m agents. Sn-GHA, Tropolone, Oxine (sulphate) and HMPAO were used to diffuse radionuclides into the platelets. The effects of time, temperature, PH of incubation media; volume and concentration of ionophore; and volume and activity of ln-l 13m C13 and Te-99m on labeling efficiency were studied.
