OBJECTIVES To investigate the role of whole-body fluorine-18-2-deoxy-2-fluoro-d-glucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) in the identification of peritoneal carcinomatosis in patients with ovarian cancer (OC). MATERIAL AND METHODS Seventy-nine patients with histologically proven stages III-IV OC who underwent (18)F-FDG PET/CT were studied retrospectively. We...

BACKGROUND (18)FDG-PET plays a significant role in diagnosing malignancy of lung lesions but remains an expensive test available at a limited number of sites in Italy. OBJECTIVE We prospectively compare the diagnostic accuracy of (99m)Tc-MIBI- SPECT and (18)FDG-PET in patients with indeterminate lung lesions to demonstrate that (99m)Tc-MIBI-SPECT may be considered as a valid alternative when ...

UNLABELLED Fine-needle aspiration biopsy (FNAB) is inconclusive in up to 20% of patients with solitary thyroid nodules. In these cases, hemithyroidectomy is necessary, but only 20% of the nodules prove to be thyroid carcinoma. The aim of this study was to explore the potential of (18)F-FDG PET to reduce the number of unnecessary hemithyroidectomies in the preoperative assessment of thyroid nodu...

OBJECTIVE To evaluate the diagnostic and prognostic role of fluorine-18 fluoro-2-deoxy-D-glucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) in comparison to morphological imaging such as computed tomography in primary adrenal malignancies. MATERIALS AND METHODS In this multicenter retrospective study, 68 patients with adrenal malignancy were included. All patients had...

PURPOSE (18)F-fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) scans are frequently performed for the screening or staging of malignant tumors. This study aimed to assess the usefulness of (18)F-FDG PET/CT in detection of gastric cancer recurrence after curative gastrectomy. MATERIALS AND METHODS Eighty nine patients who had undergone curative gastrectomy...

background: despite the relative success of surgical resection followed by proton, proton/photon, or conventional radiotherapy in terms of recurrence-free survival, chordomas are still associated with a high rate of recurrence. to our knowledge there are only very few reported cases of this rare tumor detected by f-18 fdg-pet. materials and methods: in this case we show the significance of f-18...

UNLABELLED The treatment of metastatic neuroendocrine tumors depends on the aggressiveness of the disease. We wanted to know whether (18)F-FDG PET and somatostatin receptor scintigraphy (SRS) can predict early disease progression and patient survival. METHODS We undertook a prospective study of patients with metastatic neuroendocrine tumor diagnosed between September 2003 and January 2006. Af...

UNLABELLED The lower detection rate of (18)F-FDG PET/MRI than (18)F-FDG PET/CT regarding small lung nodules should be considered in the staging of malignant tumors. The purpose of this study was to evaluate the outcome of these small lung nodules missed by (18)F-FDG PET/MRI. METHODS Fifty-one oncologic patients (mean age ± SD, 56.6 ± 14.0 y; 29 women, 22 men; tumor stages, I [n = 7], II [n = ...

OBJECTIVE Follow-up of patients with oral cavity squamous cell carcinoma (OCSCC) after tumor resection and reconstruction with tissue transfer is challenging. We compared contrast-enhanced computed tomography (ceCT), (18) F-fluorodeoxyglucose-positron emission tomography combined with noncontrast enhanced CT ((18) F-FDG-PET/CT), and (18) F-FDG-PET combined with ceCT ((18) F-FDG-PET/ceCT) to det...

UNLABELLED (18)F-FDG PET has already proved its usefulness in the follow-up of patients with alveolar echinococcosis (AE) and has been proposed as a surrogate marker for therapeutic decisions on structured treatment interruption by benzimidazoles. However, standard PET acquisition (1 h after (18)F-FDG injection) lacks sensitivity, and the parasite may stay viable even if (18)F-FDG perilesional ...
