BACKGROUND 68Ga-labelled prostate specific membrane antigen (PSMA) ligand PET/CT is a promising modality in primary staging (PS) and biochemical relapse (BCR) of prostate cancer (PC). However, pelvic nodes or local recurrences can be difficult to differentiate from radioactive urine. CT urography (CT-U) is an established method, which allows assessment of urological malignancies. The study pres...

BACKGROUND/AIMS 18F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) has been used for preoperative staging of colorectal cancer (CRC). However, the diagnostic accuracy of FDG-PET/CT for detection of lymph node or distant metastasis and its prognostic role have not been well established. We therefore evaluated the diagnostic and prognostic value of FDG-PET/CT in ...

Positron emission tomography (PET)/computed tomography (CT), which combines the advantages of high sensitivity and specificity of PET and high resolution of CT, is a unique tool for cancer management. PET/CT has been widely used in cancer diagnosis and treatment. The article reviews the recent applications of PET/CT in radiation oncology, with a focus on (18)F-fluorodeoxyglucose (FDG)-PET/CT, a...

OBJECTIVES To determine the efficacy of combined positron emission tomography-computed tomography (PET-CT) in identifying recurrent thyroid cancer and to elucidate its role in the clinical management of thyroid carcinoma. DESIGN Retrospective study. SETTING Tertiary care referral academic center. PATIENTS One hundred twenty-four patients with previously treated thyroid carcinoma who under...

Objectives: The aim of this study was to compare F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/magnetic resonance (MR) (with and without diffusion-weighted imaging [DWI]) to F-FDG PET/computed tomography (CT), with regard to the assessment of nodal and extranodal involvement, in patients with Hodgkin lymphoma and non-Hodgkin lymphoma, without restriction to FDG-avid subytpes. Ma...

OBJECTIVES/HYPOTHESIS Combined positron emission tomography with simultaneous computed tomography (PET/CT performed using 18F-fluorodeoxyglucose [FDG] as a radiopharmaceutical) results in improvement in anatomic localization of tumor. This review explores the contemporary application of PET/CT to pretreatment assessment, posttreatment monitoring, and subsequent treatment planning for patients w...

Neuroendocrine tumors (NETs) are relatively rare and heterogeneous, mostly asymptomatic discovered incidentally. PET-CT is one of the gold diagnostic standards typically detects well-differentiated NETs using 68Gallium-Dotatate (Ga-PET/CT) more aggressive undifferentiated 18F-FDG (FDG-PET/CT). However, some displaying atypical high-grade features being detected on FDG-PET/CT. In this study, we ...

Aim of the performed clinical study was to compare the accuracy and cost-effectiveness of PET/CT in the staging of non-small cell lung cancer (NSCLC). Material and Methods. Cross-sectional and prospective study including 103 patients with histologically confirmed NSCLC. All patients were examined using PET/CT with intravenous contrast medium. Those with disease stage ≤IIB underwent surgery (n =...

AIM To evaluate the role of 18F-fluorodeoxyglucose (FDG) PET/CT in: a) the selection of patients with locally advanced pancreatic cancer for helical tomotherapy with concurrent chemotherapy (HTT-ChT); b) monitoring HTT-ChT treatment efficacy in comparison with contrast-enhanced CT (c.e.CT). METHODS Forty-two consecutive patients with unresectable locally advanced pancreatic cancer referred fo...
