The effect of iron overload on radiopharmaceuticals's uptake in bone scan is known since 1975. Dissociation of Tc-99m from the carrier ligand due to the presence of iron excess seems the most plausible hypothesis. Free Tc-99m can be bound to other tissular substrates which can explain extra...

Extraosseus Uptake with Bone Scintigraphy: Renal Mesenchymal Chondrosarcoma with Metastasis We report a case of mesenchymal chondrosarcoma of the kidney in a 15-year-old boy who presented with a palpable metastatic focus in the right axilla. Bone scintigraphy performed as part of the initial evaluati...
"We were able to detect lymph node, bone, and visceral metastases in both castration-sensitive and castration-resistant prostate cancer," he reported. And there was "no evidence of uptake inhibition by high serum folate levels." SUGGESTED for you ...
There was avid an 18F-FDG uptake in all areas of the bone marrow and the spleen indicating long-term infection. A few lymph nodes are visible in the upper mediastinum on the 68Ga-DOTANOC scan. Right panel: transaxial and coronal slices of the cardiac region revealed avid 18F-FDG uptake ...
(necessary in all subjects for the gallbladder). Bone marrow radiotracer uptake was considered as an estimate for red marrow. The International Commission on Radiological Protection (ICRP 30) gastrointestinal (GI) model (ICRP 1979) was used to determine the normalized cumulated activities (NCA) ...
Our observations of variation in the uptake of 11C-erlotinib further suggest that not all tumours in the same patient are driven by EGFR signalling, and therefore may not respond to erlotinib treatment. Staging of lung cancer is crucial when deciding treatment options and the prognosis also ...
First, the targeting potential of the [99mTc]Tc-Nbs was assessed in CD8+ SUP-T1 tumor-bearing nude mice, which lack endogenous T cells, by SPECT/CT imaging 1 h after intravenous (i.v.) injection (Fig. 4a). Both [99mTc]Tc-Nbs showed a high uptake in the kidneys and the ...
