UNLABELLED Clarifying the diagnosis of clinically suspected recurrence of cervical cancer can be challenging. The aim of this study was to investigate the clinical value of (18)F-FDG PET in this context. METHODS The medical records of a cohort of 40 (18)F-FDG PET referrals in whom recurrence of cervical cancer was clinically suspected were reviewed. Two expert gynecologic oncologists assessed...

INTRODUCTION (18)F-FDG-PET visualises inflammation. Both atherosclerosis and giant cell arteritis cause vascular inflammation, but distinguishing the two may be difficult. The goal of this study was to assess interobserver agreement and diagnostic accuracy of (18)F-FDG-PET for the detection of large artery involvement in giant cell arteritis (GCA). METHODS 31 (18)F-FDG-PET/CT scans were selec...

Unintentional intraarterial injection of radiotracers may cause artifacts leading to difficulties in accurately interpreting PET/CT images. We report a case of a 73-y-old man with a history of metastatic colon cancer who underwent a PET/CT scan for restaging. In the PET scan, there was intense and diffuse distribution of (18)F-FDG in his left forearm and hand. This is a classic sign of an accid...

We describe a patient with newly diagnosed limy cancer. Staging was performed with CT and mediastinoscopy. FDG PET scan was performed and confirmed increased metabolic activity in the primary tumor as well as the hilar lymph node. Seven months after initial presentation, the patient was found to have two lytic lesions in the pelvis on plain radiograph. Hone scan was negative but PET demon...

FDG-PET is a sensitive but not specific test for myocardial sarcoidosis and its ability to define prognosis remains unclear. Combination with perfusion scanning may improve accuracy by differentiating scar from inflammation. We conducted this retrospective chart review to ascertain the utility of a rubidium -FDG PET scan for assessment of disease activity in patients with cardiac sarcoidosis. T...

BACKGROUND In many centers, (18)F-fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) is used to monitor treatment response after definitive (chemo)radiotherapy [(C)RT] for head and neck squamous cell carcinoma (HNSCC), but its usefulness remains somewhat controversial. We aimed at assessing the accuracy of FDG-PET/CT in detecting residual disease after (C)RT. MET...

UNLABELLED We present the case of a 56-year-old man with the clinical diagnosis of ocular melanoma. As a part of staging, he underwent an F-18 FDG PET/CT scan for investigating distant metastasis. On PET scan, an increased focal area of F-18 FDG uptake was seen behind patient's right knee that can be confused with distant metastasis. On CT scan, there was a fluid density in the same location. T...

BACKGROUND Post-radiotherapy nasopharyngeal changes represent a diagnostic dilemma. Early detection of persistent or recurrent disease may be translated to better cure rate if salvage therapy is implemented. Neither clinical exam nor current radiological anatomical studies (CT/MRI) can differentiate between benign post therapy changes and recurrence. PET scan is a functional study capable of id...

RATIONALE to evaluate the role of 18F-fluorodeoxyglucose positron emission tomography ([(18)F]FDG-PET) integrated with computer tomography (CT) scan [(18)F]FDG-PET/CT in the staging and target volume definition in Intensity Modulated RapidarcTM Delivery (RA-IMRT) in cervical cancer. METHODS From June 2010 to December 2011, 66 patients affected by cervical cancer, candidates for definitive or ...

BACKGROUND Limited data suggest that fluorine-18 fluoro-2-deoxy-D-glucose (F-18 FDG) positron emission tomography combined with computed tomography (PET/CT) scan may be useful for diagnosing infections of the spine. Brucellar spondylodiskitis might be devastating and current imaging techniques lack sensitivity and specificity. The aim of this prospective study was to determine the role of F-18 ...
