UNLABELLED The goal of this study was to assess the value of hybrid imaging using a combined PET/CT device with 18F-FDG in the diagnosis and clinical management of suspected recurrent lung cancer. METHODS Forty-two patients with non-small cell lung cancer (NSCLC) with suspected recurrence due to new clinical, biochemical, and radiologic findings were prospectively evaluated. PET/CT results we...

18F-fluorodeoxyglucose (FDG)-positron emission tomography (PET)/computed tomography (CT) has the potential to improve the staging and radiation treatment (RT) planning of various tumor sites. However, from a clinical standpoint, questions remain with regard to what extent PET/CT changes the target volume and whether PET/CT reduces interobserver variability in target volume delineation. The pres...

PURPOSE The objective of this study was to prospectively evaluate various quantitative metrics on FDG PET/CT for monitoring sunitinib therapy and predicting prognosis in patients with metastatic renal cell cancer (mRCC). METHODS Seventeen patients (mean age: 59.0 ± 11.6) prospectively underwent a baseline FDG PET/CT and interim PET/CT after 2 cycles (12 weeks) of sunitinib therapy. We measure...

BACKGROUND The purposes of this study are to evaluate the prognostic value of posttreatment (18)F-FDG PET/CT in predicting the survival of patients with ovarian carcinoma and to determine incremental value of combining posttreatment PET/CT with traditional prognostic factors in a multivariate model. METHODS This was an IRB-approved retrospective study. From July 2001 to July 2011, 48 patients...

PURPOSE To assess the clinical value of FDG PET/CT and evaluate the complementary roles of serum squamous cell carcinoma antigen (SCCAg) and FDG PET/CT in the diagnosis of suspected recurrent of cervical squamous cell cancer. METHODS Serum SCCAg levels were retrospectively reviewed in patients previously treated for cervical squamous cell carcinoma, who had suspected recurrence of cervical ca...

Ispitanici metode: Retrospektivno analizirano 120 SR SPECT/CT snimanja patohistološki dokazani...

Background: To retrospectively describe imaging characteristics of liver metastases on fused FDG-PET/ MRI data sets and to compare the diagnostic accuracy of MRI and fused FDG-PET/MRI data sets for the detection of liver metastases in patients undergoing systemic anticancer treatment. Materials and Methods: 43 oncological patients (mean age: 56+/- 11 years) were investigated by FDG-PET...

UNLABELLED Rising serum tumor markers may be associated with negative imaging in the presence of cancer. CT and (18)F-FDG PET may yield incongruent results in the assessment of tumor recurrence. The present study evaluates the incremental role of (18)F-FDG PET/CT for the diagnosis and management of cancer patients with increasing levels of tumor markers as the sole indicator of potential recurr...

b-cell lymphoblastic lymphoma (b-lbl) is an uncommon subtype of pediatric non-hodgkin lymphoma (nhl) which rarely involves the skin primarily. the positron emission tomography with 2-deoxy-2-[fluorine- 18] fluoro-d: -glucose integrated with computed tomography (18f-fdg pet/ct) scan findings of a 8-year-old boy with cutaneous b-lbl were presented. pet/ct scan demonstrated mild fdg uptake in the ...

PurposeThis study investigated the value of Fluorine-18 2-fluoro-2-deoxy-D-glucose (FDG) positron emission tomography (PET)/computed tomography (CT) imaging in the management of patients with advanced penile cancer.Patients and MethodsBetween January 2009 and August 2012, 48 patients with penile cancer at our center underwent FDG-PET/CT after CT (n=39) or magnetic resonance imaging (MRI; n=9). ...
