- Complementary findings on 18F-FDG PET/CT and 18F-NaF PET/CT in a patient with Erdheim-Chester disease(2017) SABINO, Daniela; VALE, Romulo Hermeto Bueno do; DUARTE, Paulo Schiavom; SAPIENZA, Marcelo Tatit; BUCHPIGUEL, Carlos Alberto
- Preliminary Comparison of PET/CT Studies Performed After Intravenous and Oral Administration of F-18-Fluoride(2016) ZACCHI, Samara Riguete; VALE, Romulo Hermeto Bueno do; DUARTE, Paulo Schiavom; SAPIENZA, Marcelo Tatit; BUCHPIGUEL, Carlos AlbertoA 78-year-old man with prostate cancer was referred for F-18-NaF PET/CT for assessing bone metastases. An F-18-NaF PET/CT study was performed after the intravenous administration of the radiopharmaceutical. Five days later, a second study was done after oral administration of the radiopharmaceutical as part of a research protocol.
- F-18-FDG PET/CT Osteometabolic Activity in Metastatic Parathyroid Carcinoma(2016) VALE, Romulo Hermeto Bueno do; QUEIROZ, Marcelo Araujo; COUTINHO, Artur Martins Novaes; BUCHPIGUEL, Carlos Alberto; MENEZES, Marcos Roberto deParathyroid cancer is an uncommon type of malignancy, which is frequently associated with poor prognosis. Clinical manifestations are caused by elevated serum calcium and parathyroid hormone (PTH). Diagnostic imaging studies as neck ultrasonography, technetium Tc Tc-99m-sestamibi whole body scintigraphy, CT, and MR are already established tools for this malignancy. Nevertheless, the role of F-18-FDG PET/CT remains unknown in this scenario, with few published studies in literature. Hence, in this article, we aimed to report an illustrative case of increased skeletal FDG uptake associated with high calcium and PTH levels.

Materials and Methods: We analyzed the medical charts of 74 Hodgkin lymphoma patients who underwent 18F-FDG positron emission tomography/computed tomography (PET/CT) prior to the initiation of therapy between October 2010 and September 2013. In all of the patients, the bone marrow biopsy was negative and the 18F-FDG PET/CT images did not suggest bone marrow involvement. Of the 74 patients evaluated, 54 presented inflammatory (B) symptoms and 20 did not. Regions of interest (ROIs) were drawn on the sternum, the proximal thirds of the humeri, the proximal thirds of the femora, and both iliac wings (totaling seven ROIs per patient). To compare the patients with and without B symptoms, in terms of standardized uptake values (SUVs) for the seven ROIs, we used the Mann-Whitney U test. Results: For six of the ROIs, the SUVs were higher in the patients with B symptoms than in those without, and the difference was statistically significant (p < 0.05). There was also a tendency toward a statistically significant difference between the two groups in terms of the SUV for the right iliac wing ROI (p = 0.06). Conclusion: In our sample, the presence of B symptoms was associated with increased 18F-FDG uptake in bone marrow.

Herein, we report a case of F-18-fluoride uptake in lymph nodal and hepatic metastases of medullary thyroid carcinoma. Simultaneous CT showed calcified lesions in these regions.
