invasive apocrine carcinoma (iac) of the breast is a rare subtype of breast malignancy. its incidence is not well known, but it is approximately less than 1% to 4%. for these reasons, there are few reports and little information on the radiologic appearance of iac. furthermore, most of the case reports show malignant features which are similar to invasive ductal carcinoma (idc). we present a ra...

Objective(s): Considering the fact that the standardized uptake value (SUV) of a normal lung tissue is expressed as x±SD, x+3×SD could be considered as the threshold value to outline the internal tumor volume (ITV) of a lung neoplasm. Methods: Three hollow models were filled with 55.0 kBq/mL fluorine18- fluorodeoxyglucose (18F-FDG) to represent tumors. The models were fixed to a barrel filled w...

Colorectal cancer represents the second most common malignancy worldwide, with approximately one million newly diagnosed cases each year, and is the fourth leading cause of cancer mortality. This article provides an overview of the role of FDG (fluorodeoxyglucose) PET (positron emission tomography) CT (computed tomography) for assessment in patients with colorectal cancer. A summary of key lear...

Mediastinal inflammatory pseudotumor is a rare benign disease with its capability for local invasion and rapid growth. We present a case of middle-mediastinal inflammatory pseudotumor and report its contrast-enhanced chest computed tomography, (18)F-fluorodeoxyglucose positron emission tomography/computed tomography and pathologic findings.

Spontaneous regression of metastatic melanoma is a rare event with only 76 cases having been reported since 1866. The precise mechanism of regression remains unknown. We present a case of a man with spontaneous regression of pulmonary metastatic melanoma confirmed on histopathology accompanied by reduction in fluorodeoxyglucose-activity on serial positron emission tomography/computed tomography...

Background Fever of unknown origin (FUO) and unexplained signs of inflammation are challenging medical problems and predominantly caused by infections, malignancies and noninfectious inflammatory diseases. The aim of this study was to assess the diagnostic value of fluorine-18 fluorodeoxyglucose positron emission tomography (18F-FDGPET) and of its combination with computer tomography technology...

One decade ago, James Rudd, who also coauthored the present article, published the results of the first prospective trial investigating F-fluorodeoxyglucose (FDG) positron emission tomography (PET) for imaging of inflammatory changes in carotid artery disease in Circulation.1 Since that time, FDG-PET has emerged as a powerful noninvasive technique to measure vascular inflammation due to atheros...

Retroperitoneal fibrosis is an uncommon disease characterized by inflammatory fibrosis typically surrounding abdominal aorta and iliac arteries. The glucose analogue F18-fluorodeoxyglucose can be used to image inflammatory cell activity non-invasively by PET. In this report we investigated the usefulness of the FDG PET/CT in the disease activity and therapy response evaluation of retroperitonea...

Fluorodeoxyglucose positron emission tomography ((18)FDG-PET) is currently the best noninvasive test to confirm hepatic metastases when diagnostic uncertainty exists after initial imaging with first-line modalities. However, we report the second case of "false-positive" uptake of (18)FDG on PET scanning from a histopathologically confirmed hepatic adenoma.

Fluorodeoxyglucose positron emission tomography (PET) combined with computed tomography (CT) identifies patientswith early response to chemotherapy, forwhom radiotherapymay be avoided. The role of PET-CT in upfront risk stratification and response–adapted treatment is evaluated ...
