UNLABELLED Prior studies have documented increased (18)F-FDG adrenal activity in both benign and malignant pathologic conditions. When whole-body PET imaging is performed without CT anatomic coregistration, however, the normal adrenal gland is difficult to recognize. The purpose of this study was to investigate the normal adrenal appearance and standardized uptake value (SUV) using (18)F-FDG PE...

Two years after resection of a left parietal glioma, a 46-year-old woman underwent F-FDG and F-DOPA brain PET/CT. FDG showed left parietal hypometabolism with crossed cerebellar diaschisis. No abnormally increased FDG activity was seen. F-DOPA PET/CT scan demonstrated focal left parietal uptake. Recurrent glioma was confirmed by surgical biopsy. F-DOPA may demonstrate abnormal amino acid metabo...

UNLABELLED In this pilot study, we evaluated 3'-deoxy-3'-(18)F-fluorothymidine (FLT) PET for the detection of gastric cancer and compared the diagnostic accuracy with that of (18)F-FDG PET. METHODS Forty-five patients (31 male and 14 female) with histologically proven locally advanced gastric cancer underwent attenuation-corrected whole-body (18)F-FLT PET and (18)F-FDG PET/CT (low-dose CT). (...

BACKGROUND & OBJECTIVE Because (18)F-FDG PET/CT can display cancer lesion morphology, size and the relatinship of the cancer lesion to adjacent tissues, it is used in the diagnosis and classification of nasopharyngeal carcinoma (NPC). This study was to explore the application value of (18)F-FDG PET/CT in TNM staging by comparing the performance of MRI and PET/CT together with pathological resul...

Ocular sebaceous adenocarcinoma is a rare malignant tumor. We report an unusual case of orbital sebaceous adenocarcinoma in a 48-year-old woman. The patient underwent F-18 2-fluoro-2-deoxy-glucose positron emission tomography/computed tomography ((18)F-FDG-PET/CT) to determine the initial clinical stage. (18)F-FDG-PET/CT showed strong uptake in the orbital lesion, but neither regional lymphatic...

BACKGROUND 18F-fluoro-deoxy-glucose (18 F-FDG) positron emission tomography integrated/combined with computed tomography (PET-CT) provides the best diagnostic results in the metabolic characterization of undetermined solid pulmonary nodules. The diagnostic performance of 18 F-FDG is similar for nodules measuring at least 1 cm and for larger masses, but few data exist for nodules smaller than 1 ...

We report the case of a 60-year-old woman with metastatic high-grade uterine leiomyosarcoma who achieved a delayed response to second-line therapy with the marine-derived drug trabectedin (Yondelis(®), PharmaMar). We used 2-deoxy-2-[(18)F] fluorodeoxyglucose (FDG)-positron emission tomography (PET-CT) imaging as a tool for response monitoring in parallel with conventional re-staging according t...

a 60-year-old patient with testicular seminoma was referred for f-18 fdg pet/ct study to evaluate recurrence. in addition to hypermetabolic cervical, mediastinal and hilar lymph node tumoral metastases, segmental intense fdg uptake along the lumbar spinal cord suggestive of tumoral metastasis was noted which quite an unusual presentation is.  at the time of pet study the patient was symptomless...

PURPOSE We evaluated the utility of magnetic resonance imaging (MRI) and (18)F-fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) for the preoperative staging of invasive lobular carcinoma (ILC) of the breast and compared the results with those of invasive ductal carcinoma (IDC). METHODS The study included pathologically proven 32 ILCs and 73 IDCs. We compa...

UNLABELLED Lung cancer often coexists with acute and chronic lung diseases such as chronic obstructive pulmonary disease. Therefore, mediastinal lymph nodes may be false-positive on (18)F-FDG PET because of the inflammatory disease alone. Nevertheless, (18)F-FDG PET/CT is the primary imaging modality used for staging patients with lung cancer, including nodal status. The purpose of this study w...
