In a mouse model of human lung cancer, intratumoral distribution between 3'-deoxy-3'-[18F] fluorothymidine (18F-FLT) and [18F] fluorodeoxyglucose (18F-FDG) was mutually exclusive. 18F-FLT primarily accumulated in proliferating cancer cells, whereas 18F-FDG accumulated in hypoxic cancer cells. The aim of the present study was to evaluate these preclinical findings in patients with lung cancer. A...
Cilj: Cilj rada bio je procijeniti doprinos jednofotonske emisijske tomografije / kompjutorizirane somatostatinskih receptora (SR SPECT/CT) s 99mTc-EDDA/HYNIC-Tyr3-oktreotidom (99mTc-Tektrotyd) u dijagnostici i procjeni proširenosti bolesti kod pacijenata oboljelih od neuroendokrinih tumora (NET-ova). Ispitanici metode: Retrospektivno analizirano 120 SR SPECT/CT snimanja patohistološki dokazani...
Multimodality imaging, as represented by its greatest exponent, PET/CT, has a firm place in the evaluation of a patient presenting with cancer. With 18F-FDG, PET/CT is rapidly becoming the key investigative tool for the staging and assessment of cancer recurrence. In the last 5 y, PET/CT has also gained widespread acceptance as a key tool used to demonstrate early response to intervention and t...
Abstract Background 8–28% of patients infected with COVID-19 have evidence cardiac injury, and this is associated an adverse prognosis. The cardiovascular mechanisms injury are poorly understood speculative. We aim to use multimodality imaging including magnetic resonance (CMR) imaging, computed tomography coronary angiography (CTCA) positron emission 2-deoxy-2-[fluorine-18]fluoro- d -glucose i...
UNLABELLED Our objective was to evaluate the accuracy of PET/CT for the diagnosis of Richter's transformation of chronic lymphocytic leukemia (CLL) to diffuse large cell lymphoma. METHODS A retrospective study was performed of 37 patients with CLL who underwent 18F-FDG PET/CT at our institution between March 2003 and July 2005. All PET/CT scans were reviewed in consensus by 2 diagnostic radio...
Intravascular large B-cell lymphoma (IVLBCL) is a rare and aggressive subtype of systemic extranodal non-Hodgkin diffuse large B-cell lymphoma (DLBCL). We report a rare case of IVLBCL who showed diffuse 18F-fluorodeoxyglucose (FDG) uptake in the lung in FDG-positron emission tomography/computed tomography (PET/CT) without respiratory symptoms or chest CT abnormalities. Serum biochemical studies...
The aim of this study was to evaluate whether the development of hepatocellular carcinoma (HCC) in murine models resembles tumor progression in humans, using non‑invasive molecular imaging methods. Murine HCC models were generated by treating mice with diethylnitrosamine (DEN) or by the transgenic expression of hepatitis B virus X (HBx) protein (HBx-Tg model). Tumor development was detected usi...
PURPOSE We aimed to investigate the accuracy of 18F-fluorodeoxyglucose positron emission tomography/magnetic resonance imaging (18F-FDG PET/MRI) compared with contrast-enhanced 18F-FDG PET/computed tomography (PET/CT) for the characterization of incidental tracer uptake in examinations of the head and neck. METHODS A retrospective analysis of 81 oncologic patients who underwent contrast-enhan...
OBJECTIVE The aim of this study was to evaluate the clinical significance of incidental focal uptake of 18F-fluorodeoxyglucose (18F-FDG) on positron emission tomography/computed tomography (PET/CT) in the prostate glands of cancer patients. METHODS A retrospective review of 3122 consecutive male patients who underwent 18F-FDG PET/CT studies with an oncologic indication, over the course of fou...
Background: 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/ CT) has become an established method for detecting hypermetabolic sites of known and occult disease and is widely used in oncology surgical planning. Intraoperatively, it is often difficult to localize tumors and verify complete resection of tumors that have been previously detected on diagnostic...
