The aim of this retrospective analysis was to describe our clinical experience for fluorine-18 (F) fluorodeoxglucose (FDG) positron emission tomography/computed tomography (PET/CT) in patients with soft tissue and osseous sarcoma. Total of 26 F-FDG PET/CT scans were evaluated in 17 patients (7 osteosarcoma, 5 Ewing’s sarcoma, 3 uterine sarcoma and 2 rhabdomyosarcoma) in different stages of dise...

An inflammatory pseudotumor (IPT) is a rare benign lesion, characterized by nonneoplastic proliferation of inflammatory cells and presence of intermingling collagen fibers. IPT commonly occurs in the lungs and orbita, while an intraspinal IPT is extremely rare. IPT can mimic both clinically and radiologically malignant processes, and making a definitive preoperative diagnosis is often difficult...

Peritoneal lymphomatosis is an extremely rare presentation of lymphoma. Due to its relative low frequency, it receives much less attention than peritoneal carcinomatosis. The challenge is to differentiate between lymphomatosis and carcinomatosis, as well as peritoneal tuberculosis or other pathologic entities within the peritoneal cavity based essentially on radiologic features. 18</...

UNLABELLED Accurate evaluation of primary tumors and cervical lymph node status of squamous cell carcinoma (SCC) of the oral cavity is important to treatment planning and prognosis prediction. In this prospective study, we evaluated the use of 18F-FDG PET, CT/MRI, and their visual correlation for the identification of primary tumors and cervical nodal metastases of SCC of the oral cavity with h...

Computed tomography (CT), the standard method to assess tumor response to cetuximab in incurable squamous cell carcinoma of the head and neck (SCCHN), performs poorly as judged by the disparity between high disease control rate (46%) and short time to progression (TTP) (70 days). F-18 fluorodeoxyglucose positron emission tomography (FDG-PET)/CT is an alternative method to assess tumor response....

The management of residuals after completion of chemotherapy in advanced seminoma is controversial. It has been proposed that fluorodeoxyglucose-positron emission tomography (FDG-PET) can be used as a follow-up. In this study we investigated FDG-PET as a follow-up tool in advanced seminoma patients treated previously with chemotherapy or radiotherapy. Thirty-seven patients assigned to an advanc...

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...

Objectives: To investigate the role of whole-body fluorine-18-2-deoxy-2-fluoro-d-glucose positron emission tomography/computed tomography (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 F-FDG PET/CT were studied retrospectively. We conside...

Aggressive histological subtypes of thyroid cancer are rare and have a poor prognosis. The most important aggressive subtypes of thyroid cancer are Hürthle cell carcinoma (HCTC) and anaplastic and poorly differentiated carcinoma (ATC and PDTC). The American Thyroid Association recently published guidelines for the management of patients with ATC, but no specific guidelines have been done about ...

UNLABELLED The aim of this study was to assess the diagnostic performance of (18)F-FDG PET and integrated (18)F-FDG PET/CT for diagnosing recurrent esophageal cancer after initial treatment with curative intent. METHODS The PubMed, Embase, and Cochrane library were systematically searched for all relevant literature using the key words "(18)F-FDG PET" and "esophageal cancer" and synonyms. Stu...
