We report a case of Hodgkin lymphoma (classic type) referred for response assessment after two cycles of chemotherapy with ABVD regiment. The F-18 fluorodeoxyglucose positron emission tomography (F-18 FDG PET/CT) showed hypermetabolic cutaneous and subcutaneous lesions with a linear pattern in the left arm with significant F-18 fluorodeoxyglucose positron accumulation in associate with left axi...

Introduction Range and diffusion of positron-emitting radiopharmaceuticals are important parameters for image resolution in positron emission tomography (PET). In this study, GEANT4 toolkit was applied to study positron diffusion in soft tissues with and without a magnetic field for six commonly used isotopes in PET imaging including 11C, 13N, 15O, 18F, 68Ga, and 82Rb. Materials and Methods GEA...

A 71-year-old woman was referred to our tertiary care center for evaluation of asymptomatic recurrence of primary hyperparathyroidism. As per our protocol, the patient underwent neck/mediastinum F-fluorocholine (FCH) positron emission tomography-computed tomography (PET-CT) for localization. In our institution, FCH PET-CT is performed in patients with hyperparathyroidism and negative convention...

INTRODUCTION Fluorodeoxyglucose positron emission tomography scanning has an established role in the diagnostic work-up of many malignant diseases and also in the evaluation of cancer treatment response. Fluorodeoxyglucose positron emission tomography may, however be non-specific as infectious processes are depicted as well. CASE PRESENTATION We present a patient with longstanding leg pain an...

Breast cancer is one of the deadliest cancers in world. It essential to detect signs as early possible, make survival rate higher. However, detecting breast using machine or deep learning algorithms from diagnostic imaging results not trivial. Slight changes illumination scanned area can significantly affect automatic classification process. Hence, research aims propose an classifier for digita...

BACKGROUND The value of performing post-therapy routine surveillance imaging in patients with Hodgkin lymphoma is controversial. This study evaluates the utility of positron emission tomography/computed tomography using 2-[18F]fluoro-2-deoxyglucose for this purpose and in situations with suspected lymphoma relapse. DESIGN AND METHODS We conducted a multicenter retrospective study. Patients wi...

We investigated sensitivity, specificity, positive predictive value, negative predictive value and accuracy of 18F-fluorodeoxyglucose-positron emission tomography in 170 cases with suspected or biopsy-proven posttransplant lymphoproliferative disorder. All solid organ and hematopoietic stem cell transplant recipients who underwent an 18F-fluorodeoxyglucose-positron emission tomography scan betw...

I. ABSTRACT We are developing a high specificity technique for detecting the increased metabolic rate of breast tiiinours. The glitcose analog FDG is known to concentrate in breast tiinlours rendering them easily detectable in conventional PET scans. Since PET is a relatively expensive imging technique it has not been used routinely in the detection of breast cancer. Positron emission mtnrnogra...
