OBJECTIVE The aim of this study is to evaluate the diagnostic performance of FDG-PET/CT for the detection of residual disease after (chemo)radiotherapy in patients with head and neck squamous cell carcinoma (HNSCC) and to evaluate the prognostic value of the FDG-PET/CT findings. METHODS Patients with HNSCC who underwent FDG-PET/CT after (chemo)radiotherapy were studied retrospectively. RESU...

The purpose of this study was to evaluate differences in histological subtypes of lung cancer using (18)F-FDG-PET 3-point imaging and kinetic analysis. Subjects comprised 44 patients with histologically proven lung cancer (squamous cell carcinoma (SCC), n=18; well-differentiated adenocarcinoma (WDA), n=9; poorly/moderately differentiated adenocarcinoma (non-WDA), n=17) who underwent (18)F-FDG-P...

Here we present a case of an untreated, asymptomatic, pulmonary hydatid cyst incidentally diagnosed on the basis of atypically low-grade (18)F-FDG uptake in the peripheral rim and a minimal increase in uptake on dual-point (18)F-FDG PET/CT. The patient underwent (18)F-FDG PET/CT for characterization of a solitary lung lesion found on chest radiography and inconclusive findings on contrast-enhan...

increased metabolic activity in muscle secondary to excessive muscle activity during the uptake phase and shortly before fdg injection is a known phenomenon. we present fdg pet/ct findings in a young male, known case of carcinoma maxilla his scan showed diffuse increased metabolic activity in multiple skeletal muscle groups. there was history of unaccustomed, strenuous sports activity of skiing...

In this case report we describe the case of a patient with multiple bone metastases of NSCLC, adenocarcinoma with exon 21 point-mutation of EGFR, treated with gefitinib. After only 3 months, FDG-PET/CT scan showed a complete response of bone metastases and right hylar adenopathy. Implications for need of early use of FDG-PET/CT scan after gefitinib treatment are discussed.

We report on a 59-year-old female patient with an infected vascular graft investigated with 18F FDG-PET/CT. The first of two studies showed FDG activity in the left deltoid and ipsilateral axillary lymph nodes explained by influenza vaccination the day prior. The second 18F FDG-PET/CT showed multiple FDG-avid lymph nodes on both sides of the diaphragm without tracer accumulation at the vaccinat...

UNLABELLED Tumor standardized uptake values (SUVs) vary with the interval between 18F-FDG injection and image acquisition. This paper presents a simple method using a single reference point to make appropriate time corrections for tumor SUVs. METHODS The reference point method was algebraically deduced from observations made by Beaulieu et al., who found that tumor SUVs behaved linearly over ...

introduction:brain imaging with f-18 fluorodeoxyglucose (18f-fdg) positron ‎emission tomography or tc-99m hexamethylpropyleneamine oxime (‎99mtc-hmpao) spect is widely used for the evaluation of alzheimer's ‎dementia (ad); we aim to assess superiority of one method over the ‎other. methods: twenty four patients with clinical diagnosis of alzheimer disease ‎underwent 18f-fdg pet and ‎99mtc-...
