BACKGROUND The potential benefits of 18 F-fluoro-2-deoxy-D-glucose-positron emission tomography/CT (FDG-PET/CT) imaging for radiotherapy (RT) treatment planning of head and neck squamous cell carcinoma (HNSCC) are increasingly being recognized. It has been suggested that intratumoral subvolumes with high FDG avidity ("hotspots") are potential targets for selected dose escalation. The purposes o...

Introduction: One of the most commonly used radiography methods for the diagnosis of oral and dental diseases is the panoramic radiography technique. This technique is widely used due to ease of implementation, extensive coverage, time and cost savings. Dental radiography, as a routine and appropriate test, accounts for about 33% of the total radiographic examination. However, ...

UNLABELLED We conducted a comprehensive systematic review of the literature on volumetric parameters and a meta-analysis of the prognostic value of metabolic tumor volume (MTV) and total lesion glycolysis (TLG) in patients with head and neck cancer (HNC). METHODS A systematic search of MEDLINE and EMBASE was performed using the key words PET, head and neck, and volume. Inclusion criteria were...

OBJECTIVE The objective of this study was to investigate whether total lesion glycolysis (TLG) and metabolic tumor volume (MTV) measured by ¹⁸F-fluorodeoxyglucose ((18)F-FDG) positron emission tomography/computed tomography (PET/CT) could predict the aggressiveness and lymph node metastasis (LNM) in patients with incidentally detected differentiated thyroid carcinoma. METHODS A total 358 pati...

UNLABELLED In this study, we aimed to assess the prognostic value of metabolic tumor volume (MTV) and total lesion glycolysis (TLG) measured on (18)F-FDG PET/CT in pancreatic cancer patients who underwent resection with curative intent. METHODS Eighty-seven patients with pancreatic ductal adenocarcinoma who underwent (18)F-FDG PET/CT and subsequent surgical resection with curative intent with...

BACKGROUND The maximal standard uptake value (SUVmax), metabolic tumor volume (MTV), and total lesion glycolysis (TLG) of positron emission tomography/computed tomography (PET/CT) in patients with nasopharyngeal carcinoma (NPC) perform as new prognostic factors, but the outcomes of the published articles were inconclusive. In this meta-analysis, we evaluated the prognostic value of SUVmax, MTV,...

PURPOSE We evaluated the prognostic value of total lesion glycolysis (TLG) measured in baseline 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) in diffuse large B-cell lymphoma (DLBCL) treated with rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP). METHODS A total of 91 patients with newly diagnosed DLBCL underwent 18F-...
