A 46-year-old man with over a 10-year history of gout complained of progressive bilateral buttock pain with numbness of legs for 4 months. Serum uric acid level was elevated. Lumbar radiographs showed decreased density of the bilateral L4-L5 facet joints. CT showed lytic lesions of the facet joints with hyperdense periarticular lesions. Enhanced MRI showed marked enhancement of these lesions. FDG PET/CT showed avid FDG uptake of the bony and periarticular lesions with SUVmax of 16.8. A decompressive posterior lumbar laminectomy with periarticular lesion resection was performed...

Metastasis from squamous cell carcinoma of the lung to the stomach is extremely rare. F-FDG PET/CT demonstrated intense F-FDG uptake in the lower lobe of the left lung, stomach, and mediastinal lymph node in a 61-year-old man. Lower lobe of the left lung resection, mediastinal lymphadenectomy, partial gastrectomy, and esophagogastric anastomosis was performed. Immunohistochemical studies revealed squamous cell lung carcinoma in the left lung and metastatic carcinoma of gastric and lymph nodes. The present case further demonstrated the value of F-FDG PET/CT in the staging of malignant disease...

Acute appendicitis is a clinical diagnosis typically presenting with right lower quadrant pain. We describe the case of an asymptomatic 53-year-old man with stage 2A diffuse large B-cell lymphoma, who underwent F-FDG PET/CT at the completion of chemotherapy. The scan showed complete lymphomatous disease remission. Incidentally, there was increased FDG uptake in a tubular structure adjacent to the cecum. Clinical examination was negative. Subsequently, the patient presented 6 days later with typical acute appendicitis symptoms...

A 62-year-old man with asthma presented with a 1-month history of wheezing and exertional dyspnea. Although the wheezing symptoms disappeared after systemic corticosteroid therapy, the exertional dyspnea and hypoxemia did not improve. A diagnosis of intravascular large B-cell lymphoma (IVLBCL) with pulmonary involvement was suspected because of the increased serum lactic dehydrogenase (LDH) and soluble interleukin-2 receptor (sIL-2R) level, increased alveolar-arterial oxygen difference (AaDO2), decreased pulmonary diffusing capacity for carbon monoxide (DLCO) and scintigraphic, computed tomography (CT) and (18)F-fluorodeoxyglucose (FDG) positron emission tomography (PET)-CT findings...

OBJECTIVES: Depression is frequently observed in patients with systemic lupus erythematosus (SLE). Neuropsychiatric SLE (NPSLE) patients often exhibit cerebral hypometabolism, but the association between cerebral metabolism and depression remains unclear. To elucidate the features of cerebral metabolism in SLE patients with depression, we performed brain 18F-fluoro-d-glucose positron emission tomography (FDG-PET) on SLE patients with and without major depressive disorder. METHODS: We performed brain FDG-PET on 20 SLE subjects (5 male, 15 female)...

BACKGROUND: Increasing plasma glucose levels and insulin resistance can alter the distribution pattern of fluorine-18-labeled fluorodeoxyglucose (18F-FDG) in the brain and relatively reduce 18F-FDG uptake in Alzheimer's disease (AD)-related hypometabolic regions, leading to the appearance of an AD-like pattern. However, its relationship with plasma insulin levels is unclear. We aimed to compare the effects of plasma glucose levels, plasma insulin levels and insulin resistance on the appearance of the AD-like pattern in 18F-FDG images...

Targeted energy metabolism balance contributes to neural survival during ischemic stroke. Herein, we tested the hypothesis that electro‑acupuncture (EA) can enhance cerebral glucose metabolism assessed by 18F‑fluorodeoxyglucose/positron emission tomography (18F‑FDG/PET) imaging to prevent propagation of tissue damage and improve neurological outcome in rats subjected to ischemia and reperfusion injury. Rats underwent middle cerebral artery occlusion (MCAO) and received EA treatment at the LI11 and ST36 acupoints or non‑acupoint treatment once a day for 7 days...

Positron emission tomography (PET) with integrated computed tomography (CT) is a unique modality to noninvasively scan the whole body for diagnosing, staging and assessing response to therapy in various benign and malignant diseases. 18F fluorodeoxyglucose (FDG) is the most commonly used radiotracer for PET/CT imaging in cancer patients. FDG is a glucose analogue which is the predominant substrate for brain metabolism. As the brain cells are obligate glucose consumers, the knowledge of physiologic radiotracer uptake within the brain is imperative for correct interpretation of abnormal sites of metabolism...

The use of 18-F fluorodeoxyglucose (FDG) positron emission tomography (PET) with computed tomography has emerged as a crucial tool for response-adapted therapy in Hodgkin lymphoma (HL). Although more studies have focused on the predictive value of an interim or early PET obtained after 2 cycles of chemotherapy, there are indications that the end of therapy PET might even be more predictive of outcome. The optimal treatment of patients with limited stage HL who are PET-positive after chemotherapy is unknown...

We report a case of a brain abscess identified on fluorine-18 choline (FCH) positron emission tomography (PET) scan, which was not identified on fluorodeoxyglucose (FDG) PET scan. To our knowledge, there are no previous case reports of incidental brain abscess identified by FCH PET imaging. A 51-year-old man, with liver cirrhosis complicated by hepatocellular carcinoma (HCC) was enrolled in a research trial comparing HCC detection in FCH PET versus FDG PET. During the course of the trial, he underwent radiofrequency ablation (RFA) for HCC...

INTRODUCTION: Deteriorating brain glucose metabolism precedes the clinical onset of Alzheimer's disease (AD) and appears to contribute to its etiology. Ketone bodies, mainly β-hydroxybutyrate and acetoacetate, are the primary alternative brain fuel to glucose. Some reports suggest that brain ketone metabolism is unchanged in AD but, to our knowledge, no such data are available for MCI. OBJECTIVE: To compare brain energy metabolism (glucose and acetoacetate) and some brain morphological characteristics in cognitively healthy older adult controls (CTL), mild cognitive impairment (MCI) and early AD...

Malignant pleural mesothelioma (MPM) is a highly malignant pleural neoplasm with a dismal prognosis. Multimodality approach including surgery and chemotherapy are utilized to treat patients with resectable disease. Clinical staging allows for selection of patients for treatment strategies, but has not been found to be prognostic and is plagued by high interobserver variability. Tumor volume measurement on cross-sectional imaging has emerged as a potential quantitative tool with prognostic significance. This review focuses on volumetric assessment from cross-sectional imaging (CT, MRI, (18)F-FDG PET/CT) and the potential prognostic benefit and applications...
