A case of a 7-month-old white female who was referred for 18F-fluorodeoxyglucose (FDG) Positron emission tomography/computed tomography (PET/CT) initial evaluation of a lytic skull lesion with presumed diagnosis of Langerhans cell histiocytosis is described. Incidentally, she was found to have hypermetabolic nodules in the soft tissues of her anterior thighs.
Enduring complete metabolic response in metastatic adenocarcinoma of the gastro-oesophageal junction
We report on a 46-year-old gentleman who presented with a poorly differentiated invasive adenocarcinoma of the gastro-oesophageal junction, local lymph node involvement and bilobar liver metastases. Nearly 2 years after diagnosis, he has sustained complete metabolic response and remains in excellent clinical condition after treatment with chemoradiotherapy. Fluorodeoxyglucose positron emission ...
The purpose of the review is to: (a) provide information concerning the physiology of lung cancer imaging with fluorodeoxyglucose (FDG) positron emission tomography (PET); (b) clarify the role of FDG–PET in the diagnosis of solitary pulmonary nodules; (c) summarise the accuracy of PET scanning in the staging of lung cancer both in regard to mediastinal nodal staging and the staging of distant m...
BACKGROUND Rheumatoid arthritis (RA) is a systemic inflammatory condition associated with increased cardiovascular risk. This is not fully explained by traditional risk factors, but direct vascular inflammation and aortic stiffening may play a role. We hypothesized that patients with RA exhibit aortic inflammation, which can be reversed with anti-tumor necrosis factor-α therapy and correlates w...
BACKGROUND Long-term severe hyperparathyroidism leads to thinning of cortical bone and cystic bone defects referred to as osteitis fibrosa cystica. Cysts filled with hemosiderin deposits may appear colored as "brown tumors." Osteitis fibrosa cystica and brown tumors are occasionally visualized as multiple, potentially corticalis-disrupting bone lesions mimicking metastases by bone scintigraphy ...
Background—Rheumatoid arthritis (RA) is a systemic inflammatory condition associated with increased cardiovascular risk. This is not fully explained by traditional risk factors, but direct vascular inflammation and aortic stiffening may play a role. We hypothesized that patients with RA exhibit aortic inflammation, which can be reversed with anti-tumor necrosis factortherapy and correlates with...
BACKGROUND Alveolar overdistension and repetitive derecruitment-recruitment contribute to ventilator-induced lung injury (VILI). The authors investigated (1) whether inflammatory cell activation due to VILI was assessable by positron emission tomography and (2) whether cell activation due to dynamic overdistension alone was detectable when other manifestations of VILI were not yet evident. ME...
OBJECTIVE Endothelial dysfunction is an initial step in atherosclerotic cardiovascular disease. However, involvement of vascular inflammation in endothelial dysfunction is not fully investigated in humans because of the lack of diagnostic modality to noninvasively evaluate vascular inflammation. We assessed the relationship between endothelial function and vascular inflammation evaluated by [(1...
18F-fluorodeoxyglucose ([18F]-FDG) positron emission tomography/computed tomography (PET/CT) is a useful functional image technique to evaluate the disease extent in many cancers, as well differentiate benign from malignant metastasis. We report case of 49-year-old woman with breast cancer and suspected lung metastasis by conventional images. After FDG-PET/CT demonstrating faint, or even no FDG...
