Accidental diagnosis of COVID-19 pneumonia after 18F FDG PET/CT: a case series.

Purpose: The aim of this case series is to illustrate possible [18F]-FDG uptake patterns associated to COVID-19.

Methods: Retrospective assessment of all Fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) scans performed for any clinical / oncological reason from 1st April 2020 to 30th April 2020. Results of PCR testing for SARS-CoV-2 were retrieved for all patients with lung consolidations and/or peripheral ground glass opacities characterized by increased metabolism to evaluate any possible association with the viral infection.

Long-Term Metabolic Assessment of Cryopreserved Sternal Allograft: A Case Series.

Background: Sternal resection and reconstruction with cryopreserved allografts provides a safe alternative to traditional methods of anterior chest wall reconstruction. Despite favorable results, successful integration of the graft sternum has never been demonstrated owing to the invasiveness of bone biopsy. We describe our experience of using 18F-sodium fluoride positron emission tomography/computed tomography scans as a noninvasive method of evaluating graft integration.

Does the etiology of cardiac amyloidosis determine the myocardial uptake of [18F]-NaF PET/CT?

Cardiac amyloidosis (CA) leads to variable degrees of myocardial infiltration with a final echocardiographic phenotype of "hypertrophy." Although many non-invasive imaging techniques (MRI, CT, scintigraphy, PET) are useful, the definitive diagnosis is still based on myocardial histology. We explored the possible role of [18F]-NaF PET/CT in the diagnosis of this disease in two cases with wild-type (ATTRwt) or mutant (ATTRm) Ile68Leu transthyretin (TTR)-related CA.

Prognostic Value of 68Ga-DOTANOC PET/CT SUVmax in Patients with Neuroendocrine Tumors of the Pancreas.

Unlabelled: This study was performed to investigate the role of (68)Ga-DOTANOC SUVmax as a potential prognostic factor in patients with pancreatic neuroendocrine tumor (pNET).

Methods: Among the patients who underwent (68)Ga-DOTANOC PET/CT, we retrospectively collected the data of those who had G1 or G2 pNET (2010 World Health Organization classification), presented with disease on PET/CT and CT, and had at least 6 mo of follow-up. Patients with multiple endocrine neoplasia were excluded.
