Journal Article

Intratumoral Distribution of Fluorine-18-Fluorodeoxyglucose In Vivo: High Accumulation in Macrophages and Granulation Tissues Studied by Microautoradiography

Roko Kubota, +5 more
- 01 Nov 1992 - 
TL;DR: The results showed that one should consider not only the tumor cells proper but also the non-neoplastic cellular elements, which appear in association with growth or necrosis of the tumor Cells, for precise analysis of [18F]FDG uptake in tumor-bearing subjects, especially after anti-NEoplastic treatment.
Journal Article

Differential diagnosis of lung tumor with positron emission tomography: a prospective study.

Kazuo Kubota, +7 more
- 01 Dec 1990 - 
TL;DR: PET studies using either MET or FDG may be very useful for the differential diagnosis of lung tumors, and the ratios indicate that malignant tumors have higher metabolic demand than benign lesions.
Journal Article

Aortic Wall Inflammation Due to Takayasu Arteritis Imaged with 18F-FDG PET Coregistered with Enhanced CT

Yasushi Kobayashi, +6 more
- 01 Jun 2005 - 
TL;DR: The (18)F-FDG PET images coregistered with enhanced CT images showed the distribution and inflammatory activity in the aorta, its branches, and the pulmonary artery in patients with active Takayasu arteritis, even those who had weak (18), even though the intensity of accumulation decreased in response to therapy.
Journal Article

Re-evaluation of amino acid PET studies : can the protein synthesis rates in brain and tumor tissues be measured in vivo?

Kiichi Ishiwata, +6 more
- 01 Nov 1993 - 
TL;DR: Results demonstrate that uptake of the three amino acids is affected by alterations in the amino acid transport system in the brain and tumor tissues, but that only 14C-Leu uptake reflects protein synthesis rates.
Journal ArticleDOI

Usefulness of L-[methyl-11C] methionine-positron emission tomography as a biological monitoring tool in the treatment of glioma.

Tadashi Nariai, +9 more
- 01 Sep 2005 - 
TL;DR: The ability of MET-PET to reflect the biological nature of gliomas makes it an excellent method for monitoring active tumor tissue, and treatments based on its findings should provide a powerful clinical protocol in the course ofglioma therapy.
