OBJECTIVE: The purpose of this article is to summarize the evidence for the value of PET/CT for the management of patients with head and neck squamous cell cancer and suggest best clinical practices. CONCLUSION: FDG PET/CT is a valuable imaging tool for identifying unknown primary tumors in patients with known cervical node metastases leading to management change and is the standard of care for the initial staging of stage III and IV head and neck squamous cell carcinomas (HNSCCs), for assessing therapy response when performed at least 12 weeks after chemoradiation therapy, and for avoiding unnecessary planned neck dissection...

CLINICAL ISSUE: The incidence of malignant melanoma is continuously increasing. The prognosis of metastatic disease is still limited. STANDARD TREATMENT: Until a few years ago palliative chemotherapy with a limited response rate was the standard treatment for metastatic melanoma. TREATMENT INNOVATIONS: Immunotherapy and targeted therapy provide new treatment options. Immune checkpoint inhibitors have significantly improved the prognosis. DIAGNOSTIC WORK-UP: Regional lymph node sonography, computed tomography (CT) of the neck, chest and abdomen and brain magnetic resonance imaging (MRI) are routinely used...

Due to its role in infection and inflammatory processes the chemokine receptor CXCR4 might be a potent target in imaging of infectious and inflammatory diseases. The aim of this pilot study was to determine whether the CXCR4 ligand (68)Ga-Pentixafor is suitable for imaging chronic infection of the bone. Methods: The study comprises 14 patients with suspected infection of the skeleton that underwent (68)Ga-Pentixafor-(68)Ga-Pentixafor-Positron emission tomography/computed tomography(PET/CT) between 04/2015 and 02/2017 in our facility...

Objective: To investigate the value of maximum Standardized Uptake Value(SUVmax), Metabolic Tumor Volume (MTV) and Total Lesion Glycolysis (TLG) calculated from (18)F-FDG PET-CT in predicting the presence of epidermal growth factor receptor (EGFR) mutations in lung adenocarcinoma. Methods: We retrospectively reviewed 137 lung adenocarcinoma patients with EGFR mutations testing and pretreatment (18)F-FDG PET-CT. Receiver Operating Characteristic (ROC) curve analysis was performed to quantify the predictive value of SUVmax、MTV、TLG...

RATIONALE: F-fluorodeoxyglucose positron emission tomography/computed tomography (F-18 FDG PET/CT) has an important role in the diagnosis of various malignancies. However, F-18 FDG can also exhibit intense accumulation in tissues in inflammatory conditions such as active tuberculosis (TB) and sarcoidosis. PATIENT CONCERNS: We report a case of a 52-year-old female with irritable cough. CT showed a lung mass with multiple bilateral lung nodules, and sarcoidosis was suspected...

BACKGROUND: The role of (18)F-fluorodeoxyglucose-positron emission tomography (FDG-PET) in the evaluation of anaplastic large-cell lymphoma (ALCL) first presenting in the skin is not well established, while computed tomography (CT) is used as a standard procedure. OBJECTIVES: The aim of this study was to evaluate the use of FDG-PET versus CT at initial staging of ALCL first presenting in the skin. MATERIALS & METHODS: Eleven cases of ALCL first presenting in the skin who underwent both FDG-PET and CT were retrospectively analysed...

PURPOSE: To provide clinically useful gadolinium-free whole-body cancer staging of children and young adults with integrated positron emission tomography/magnetic resonance (PET/MR) imaging in less than 1 h. PROCEDURES: In this prospective clinical trial, 20 children and young adults (11-30 years old, 6 male, 14 female) with solid tumors underwent 2-deoxy-2-[(18)F]fluoro-D-glucose ([(18)F]FDG) PET/MR on a 3T PET/MR scanner after intravenous injection of ferumoxytol (5 mg Fe/kg) and [(18)F]FDG (2-3 MBq/kg)...

Although fibrous dysplasia is not considered a potentially premalignant disorder, malignant transformation occurs. Because of its rarity, radiographic features of malignantly transformed fibrous dysplasia on cross-sectional imaging modalities are less recognized, making diagnosis and differential diagnosis of the disease quite difficult in clinical practice. In this study, we analyzed the clinical characteristics, imaging features, pathology findings and surgery strategies of 19 malignantly transformed fibrous dysplasia...

PURPOSE: This study aimed to explore how patients with head and neck cancer experienced undergoing an (18)F-fluoro-deoxy-glucose positrons emissions tomography/computed tomography ((18)F-FDG PET/CT) examination in a fixation mask. METHOD: Interviews were conducted with nine patients with known or suspected head and neck cancer who were scheduled for the examination for the first time. The phenomenological method according to van Manen and his four lifeworld existentials; lived space, lived body, lived time, and lived relation was used to analyse the interviews...

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...

BACKGROUND AND PURPOSE: To compare the utility of quantitative PET/MRI, dynamic susceptibility contrast (DSC) perfusion MRI (pMRI), and PET/CT in differentiating radiation necrosis (RN) from tumor recurrence (TR) in patients with treated glioblastoma multiforme (GBM). METHODS: The study included 24 patients with GBM treated with surgery, radiotherapy, and temozolomide who presented with progression on imaging follow-up. All patients underwent PET/MRI and pMRI during a single examination...

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...

AIM: To determine the prevalence and association of mesenteric panniculitis (MP) in a group of patients with non-Hodgkin's lymphoma (NHL) compared to control group. MATERIALS AND METHODS: We retrospectively evaluated computed tomography (CT) and combined positron-emission tomography (PET) with CT examinations of a total of 166 patients who were diagnosed with NHL over a period of 5 years (2008-2013). The control group consisted of 332 subjects who were matched for gender and age at the time period the examinations were performed on the study group...

PURPOSE: Lymphoepithelioma-like carcinoma (LELC) is a rare type of gastric cancer. We evaluated the clinical usefulness of F-18 FDG positron emission tomography/computed tomography (PET/CT) in LELC of stomach. MATERIALS AND METHODS: A total of 28 patients (mean age=59years) who underwent preoperative F-18 FDG PET/CT were enrolled retrospectively. Nine patients underwent follow-up F-18 FDG PET/CT. Pathologic information was obtained through gastrectomy and the association with Epstein-Barr virus (EBV) was investigated in 26 patients...
