Spectrum of 18F-FDG Uptake in Bilateral Lung Parenchymal Diseases on PET/CT

Bilateral lung parenchymal involvement is seen in infective as well as noninfective conditions, appearing as focal or diffuse lung disease. PET/CT with FDG helps in characterization (increased glucose utilization is seen by both inflammatory and neoplastic cells). In this article, we describe the spectrum of patterns of FDG uptake and associated CT changes involving bilateral lung parenchyma. Benign conditions described are aspiration pneumonia; pulmonary toxicity by bleomycin; infections, namely, sarcoidosis, miliary pulmonary tuberculosis, and pulmonary nocardiosis; and inflammatory conditions such as pulmonary Langerhans cell histiocytosis and pulmonary alveolar proteinosis. Neoplastic conditions described are bilateral pulmonary metastases and lymphangitic carcinomatosis.

RESUMO As infec ções do trato respiratório inferior associadas à ventilação mecânica são uma das complicações mais frequentes em pacientes em ventilação mecânica. Há muitos anos, a traqueobronquite associada à ventilação mecânica tem sido considerada uma doença que não demanda antibioticoterapia . Na última década, diversos estudos demonstraram que a traqueobronquite associada à ventilação mecânica deve ser considerada um processo intermediá...

Conclusion: Respiratory ECMO support in severe acute respiratory distress syndrome patients is associated with a reduced mortality rate and a reduced need for renal replacement therapy but a substantial increase in the lengths of stay in the intensive care unit and hospital. Our results may help bedside decision-making regarding ECMO initiation in patients with severe respiratory distress syndrome.

Well, it’s been a really rough three weeks. The first thing that happened was on January 1, no kidding, when I came down with a case of the flu (much worse than the before-Xmas flu). It’s going around. A lot of people are sick with this thing. Anyway, it hit me with a very high fever and huge gastrointestinal issues. Terrible. Plus, one night, delirious with fever, I fell against the bathroom wall and injured my wrist. Ouch. Because my wrist was all swollen and hurt like the dickens, and I feared it might be fractured, Stefano took me to the emergency room at Florence’s university hospital, Careggi. We sp...

This model is based on the use of 4T1 murine breast carcinoma cells. 4T1-derived tumors recapitulate the main steps of human breast cancer progression, including epithelial-to-mesenchymal transition and metastases to lung and lymph nodes.Bioluminescence imaging revealed the appearance of secondary lesions to the lung and lymph nodes and sporadically to th...
