Abstract Background Testicular cancer is the second most frequent form of male genital tumors. Globally, testicular malignancy has risen over last forty years. Among malignant tumors, germ cell tumors represent approximately 95% all They are classified into seminomatous and non-seminomatous as they differ in clinical features, therapy, prognosis. Despite increasing value whole-body fluorodeoxyg...

INTRODUCTION Our goal was to develop cut points for amyloid positron emission tomography (PET), tau PET, flouro-deoxyglucose (FDG) PET, and MRI cortical thickness. METHODS We examined five methods for determining cut points. RESULTS The reliable worsening method produced a cut point only for amyloid PET. The specificity, sensitivity, and accuracy of cognitively impaired versus young clinica...

objective(s): this study aimed to compare the diagnostic values of 11c-choline and 18f-fluorodeoxyglucose (18f-fdg) positron emission tomography/computed tomography (pet/ct) in patients with cholangiocarcinoma (cca). methods: this prospective study was conducted on 10 patients (6 males and 4 females), aged 42-69 years, suspected of having cca based on ct or magnetic resonance imaging (mri) resu...

Contrast-enhanced computed tomography (CECT) and positron emission tomography with 18-FDG (FDG-PET/CT) are used to identify malignant solitary pulmonary nodules. The aim of the study was to evaluate the accuracy of CECT and FDG-PET/CT in diagnosing the etiology of solitary pulmonary nodule (SPN). Eighty patients with newly diagnosed SPN >8 mm were enrolled. The patients were scheduled for eithe...

OBJECTIVE To calculate the time sensitivity factor (S) for discriminating the solitary pulmonary nodule (SPN) by FDG PET at different time points. METHODS The multiple time-point FDG PET images from 41 patients for evaluating SPN seen on chest X-ray or CT were prospectively analyzed to calculate and evaluate S against the gold standard of tissue histology (n = 38) or long term clinicoradiogra...

  Introduction: Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal neoplasms of the gastrointestinal tract. GIST has been shown to over-express c-KIT (CD117), the receptor tyrosine kinase. Imatinib (STI571 or Glivec) is a new type of tyrosine kinase inhibitor that selectively inhibits various tyrosine kinases and has been successfully used to trea...

Intravascular large B-cell lymphoma (IVLBCL) is a rare and aggressive subtype of systemic extranodal non-Hodgkin diffuse large B-cell lymphoma (DLBCL). We report a rare case of IVLBCL who showed diffuse 18F-fluorodeoxyglucose (FDG) uptake in the lung in FDG-positron emission tomography/computed tomography (PET/CT) without respiratory symptoms or chest CT abnormalities. Serum biochemical studies...

In this article, we report quantitative preliminary data obtained from retrospective analysis of (18)F-fluorodeoxyglucose positron emission tomography (FDG-PET) and combined PET-computed tomography (PET/CT) examinations in subjects ages 3 to 84 years pertaining to changes in the metabolism of skin, subcutaneous adipose tissue, visceral adipose tissue, and skeletal muscle with age, as well as ag...

results fdg-pet/ct findings showed no evidence of malignant disease. there was diffusely increased fdg in soft tissue around the shoulders and hips and fdg-positive axillary lymph nodes consistent with pmr. background remitting seronegative symmetrical synovitis with pitting edema (rs3pe) is a rare, but well-defined syndrome comprising polyarthritis with symmetrical synovitis of the small joint...

Purpose: To study the relationship between (FDG) uptake expressed quantitatively as standardized uptake values (SUVs) in normal breast tissues and breast density, age, menopausal status determined during dual-time point FDGPET/CT imaging. Materials and Methods: maximum and average SUVs were determined in two hundred eighty four patients (all females; mean age 55.5 ± 14.1 range 13-84 years, 115 ...
