Background Nearly 40% of colorectal cancer (CRC) recurs within 2 years after resection of primary tumor. Imaging with fluorine-18-fluorodeoxyglucose (l8F-FDG) positron emission tomography/computed tomography (PET/CT) is the most recent modality and often applied for the evaluation of metastatic spread during the follow-up period. Our goal was to study the diagnostic importance of 18F-FDG-PET/CT...

The purpose of our study was to determine the value of different hybrid imaging combinations for the detection of focal and diffuse bone marrow infiltration in lymphoma. Patients with histologically proven lymphoma, who underwent both [18F]-FDG-PET/CT and whole-body MRI (including T1- and diffusion-weighted [DWI] sequences) within seven days, and a subsequent bone marrow biopsy, were retrospect...

OBJECTIVE Quantitative assessment of active bone marrow (BM) in vivo is yet to be well-defined. This study aims to compare total body BM volume estimations obtained from use of both18F-FLT PET/CT and 18F-FDG PET/CT in order to consolidate higher cellular proliferation rates with imaging the highly active red BM in pancreatic cancer. METHODS This phase I pilot study includes seven patients wit...

BACKGROUND AND AIM currently it is recognized the usefulness of 18F-FDG PET in assessing response to therapy with imatinib (Gleevec®) in the gastrointestinal tract sarcomas (GIST). To facilitate the follow-up of these studies is important to know the patterns of metastatic spread. The aim of this paper is to describe patterns observed in the 18F-FDG PET/CT. METHOD retrospective study included...

Correct diagnosis and definition of the functional and anatomic status of lesions in cancer patients are of clinical importance. The value of hybrid imaging using a gamma camera–based PET/CT and 18F-FDG in determining the relationship between mass and cancer was assessed. Methods: Hybrid imaging was performed using a device combining low-dose CT and gamma camera–based PET. Ninety-one patients w...

The aim of this study was to assess the value of 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) for the differentiation of peritoneal thickening of undetermined origin. This retrospective study included 103 patients (44 men and 59 women, age 59.2 ± 14.8 years) who had undergone 18F-FDG PET/CT for the evaluation of peritoneal thickening of undetermined o...

objective(s): expression of her2 in gastric carcinoma has direct prognostic and therapeutic implications in patient management. the aim of this study is to determine whether a relationship exists between standardized uptake value (suv) and expression of her2 in advanced gastric carcinoma. methods: we analyzed the 18f-fdg pet/ct results of 109 patients that underwent gastrectomy for advanced gas...

BACKGROUND AND OBJECTIVES Bone lesions in multiple myeloma (MM) have been traditionally detected by whole body X-ray (WBXR) survey although magnetic resonance imaging (MRI) has become the gold standard for detecting MM involvement of the spine and pelvis. The aim of this study was to compare a new technique, positron emission tomography (PET) with 18F fluorodeoxyglucose (FDG) integrated with co...

BACKGROUND The most frequent complications of joint arthroplasty are septic or aseptic loosening of endoprostheses. Preoperative differentiation is essential, since very different treatment methods result from the diagnoses. The aim of the current study was to evaluate the clinical value of 18F-Fluoro-deoxyglucose positron emission tomography (18F-FDG PET) as a diagnostic modality for inflammat...

2-18F-fluorodeoxysorbitol (18F-FDS) has been shown to be a promising agent with high selectivity and sensitivity in imaging bacterial infection. The objective of our study was to validate 18F-FDS as a potential radiopharmaceutical for imaging bacterial infection longitudinally in the lung. Methods: Albino C57 female mice were intratracheally inoculated with either live or dead Klebsiella pneumo...
