This study attempts to characterize thallium-201 (201TI) uptake in patients with bone and soft-tissue sarcoma and to compare these findings with gallium-67 (67Ga) and bone scintigraphy with emphasis on evaluating tumor viability before and after chemotherapy. Thirty-eight patients with
We performed a retrospective study of sixty patients who had a soft-tissue sarcoma of the extremity to determine the usefulness of scintigraphy with gallium-67 citrate as a staging modality. Abnormal activity of the gallium was present in forty-one of forty-eight sites in which there was macroscopic
The EMT-6 sarcoma-like tumor of BALB/c mice can be grown as a solid subcutaneous transplantable tumor in vivo or as a monolayer culture in vitro. We have studied the uptake of gallium-67 by this tumor growing subcutaneously on the backs of 6-week-old BALB/c mice. After i.v. administration of Ga-67
Fifty-six patients with metastatic or recurrent soft-tissue sarcoma were evaluated by 67Ga-citrate imaging. Prior to entry on the therapy protocol, 52/56 (93%) patients had true-positive 67Ga studies. Two of four patients with liposarcoma, one of twelve with leiomyosarcoma and one with an
Sequential gallium scans were performed in 37 patients with newly diagnosed osteogenic sarcoma. High gallium uptake was found more often in males in the 10 to 19 age group and in femoral lesions. High uptake was also seen in patients who had predominantly osteoblastic or mixed changes on radiographs
We reported an extremely rare case of undifferentiated endometrial stromal sarcoma imaged with gallium-67 scintigraphy. This previously healthy 32-year-old woman presented with cough and dyspnea for days. Unexpectedly, the pathology of the opacity in the right pulmonary hilar region demonstrated
In a prospective study of forty-five patients, we evaluated the usefulness of bone and gallium scintigraphy prior to definitive surgery for a soft-tissue sarcoma in an extremity. Bone scintigraphy provides a baseline for staging and often reveals periosteal invasion that is not detected by routine
Bone and gallium scans have been shown to be useful in imaging Ewing's sarcoma. Here we report on a case of recurrent Ewing's sarcoma with multiple skeletal metastases demonstrated by the FDG-PET whole body scan, while the bone scan revealed fewer lesions and a non-remarkable finding was found on
A 40-year-old Japanese man with acquired immunodeficiency syndrome was diagnosed with Kaposi sarcoma (KS) on the basis of the results of skin lesion biopsies. In addition, 18F-fluorodeoxyglucose-position emission tomography-computed tomography revealed abnormal fluorodeoxyglucose uptake in KS
We have studied the in vitro uptake of gallium-67 by exponentially growing EMT-6 sarcoma cells in long-term tissue culture. In this system, the addition of transferrin to the medium was required before an appreciable cellular uptake of Ga-67 occurred. The transferrin effect was complex, with an
This report of an 82-year-old man who presented with a 3-week history of an enlarging left axillary mass and mild fevers, highlights the usefulness of both gallium-67 and F-18 FDG PET/CT imaging in the staging of histiocytic sarcoma. While PET/CT was superior in determining the extent of the
Bone and gallium scans were performed in twelve patients with Paget's sarcoma. Most of these patients had polyostotic Paget's disease. The lesions with sarcomatous changes were usually associated with less Tc-99m MDP uptake as compared with Pagetoid bone which was not sarcomatous. Gallium uptake in
Pulmonary Kaposi sarcoma associated with acquired immunodeficiency syndrome (AIDS) is difficult to diagnose because the clinical presentations and radiographic findings are nonspecific. The authors report three proved cases of AIDS-associated pulmonary Kaposi sarcoma diagnosed with sequential
Kaposi sarcoma (KS) is a vascular-related tumor that has been associated with human immunodeficiency virus (HIV). It commonly involves the skin and lymph nodes, and infrequently involves the lungs. In very rare instances, pulmonary KS can be found in the absence of endobronchial and mucocutaneous
Primary pulmonary artery sarcoma provides perfusion-ventilation images, as well as arteriographic studies, that can suggest pulmonary embolism. The awareness of atypical correlation among the studies for pulmonary embolism can lead to an early suspicion of pulmonary artery tumor. Imaging with
