Metastatic lesions of the pancreas are uncommon, accounting for approximately 2% of pancreatic malignancies. Many tumours involve the pancreas secondarily and may manifest with different clinical and imaging characteristics. Although many patients have widespread disease, isolated metastases can be found. Surgical management is associated with improved survival in these cases. ...

Background.- Progression of migraine toward a more disabling chronic form of at least 15 days/month is linked with frequency of attacks. Magnetic resonance imaging (MRI) findings of iron accumulation in the brain, especially in periaqueductal gray and red nucleus, have been correlated with both duration of illness and frequency of ...

: Pulmonary sclerosing hemangioma (PSH), or the alternative name of "sclerosing pneumocytoma," is a rare benign neoplasm. PSH is often asymptomatic and presents as a solitary pulmonary nodule on radiologic imaging studies. Few articles have been reported to describe the FDG PET findings about PSH. We reported FDG PET findings ...

Stroking the whiskers of a rat is known to increase cerebral blood flow and glucose utilization in the somatosensory cortex. We sought to determine whether this activation could be detected with small animal PET and 2-[F]fluoro-2-deoxyglucose ([F]FDG). Awake rats were coinjected with [F]FDG and [C]deoxyglucose ([C]DG), and during the uptake ...

The prognostic value of interim PET interpreted according to visual criteria is a matter of debate in diffuse large B cell lymphoma (DLBCL). Maximal standardized uptake value reduction (ΔSUVmax) may better predict outcome. To compare the prognostic value of both methods, we analysed PET done at baseline (PET0), after 2 ...

BACKGROUND: [Fluorine-18]-fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET-CT) is widely performed in the regional nodal staging of non-small cell lung cancer (NSCLC). However, the uptake of (18)F-FDG by tubercular granulomatous tissues may lead to false-positive diagnosis. This is of special concern in China, where tubercular granulomatous disease is epidemic. Herein, ...
