OBJECTIVE
To correlate the clinical, ultrasound and pathological features of the eyes first evaluated by 18-fluorine-labelled 2-deoxy-2-fluoro-d-glucose (FDG) positron emission tomography (PET)/computed tomography and then enucleated for choroidal melanoma.
METHODS
14 consecutive patients enucleated
BACKGROUND
The current standard for neoadjuvant chemotherapy (NACT) response evaluation in osteosarcoma is histopathologic necrosis (HN). However, it is accessible only after NACT completion and may get affected by confounding factors. Thus, noninvasive surrogate such as
BACKGROUND
Sarcoid granuloma formation involves the orchestration of cytokines and chemokines, which modulate the host's immune response to the antigen stimulus. The release of cytokines enhances expression of the pro-inflammatory cytokine tumour necrosis factor-alpha (TNF), which plays a crucial
OBJECTIVE
To determine if the location of the point of maximum standardized uptake value (SUVmax) being included in or not included in the histopathologic slab section corresponded to tumor necrosis or survival.
METHODS
Twenty-nine osteosarcoma patients underwent post-chemotherapy
OBJECTIVE
The objective was to present a method for the repeated noninvasive measurement of tumor oxygenation (Po(2)) over the whole period of tumor growth.
METHODS
A mixture of tumor homogenate (GH3 prolactinoma) and alginate capsules loaded with perfluoro-15-crown-5-ether (15C5) was injected into
A 62-year-old male presented with sudden onset of low back and right leg pain. Contrast-enhanced computed tomography demonstrated an abdominal aortic aneurysm (AAA), along with a large mass lesion causing vertebral body erosion. Magnetic resonance imaging (MRI) suggested that the mass lesion
OBJECTIVE
To study whether volume-based indices of fluorine 18 fluorodeoxyglucose positron emission tomographic (PET)/computed tomographic (CT) imaging is an accurate tool to predict the amount of residual viable tumor after induction chemotherapy in patients with locally advanced non-small cell
OBJECTIVE
To reveal the structural basis of protective influence of the natural ceolite enterosorbents in fluorine intoxication.
METHODS
Fluorine effect was realized by exposure of 15 rats of Vistar's line in electrolysis shops of an aluminium plant. 15 animals were in normal ecological conditions
High grade gliomas (HGG) frequently recur regardless of treatment. Radiological detection of progressive disease (PD) is challenging due to the possibility of therapy-related MRI changes including: pseudoprogression (PP) and radiation necrosis (RN). Both may mimic PD. We undertook a literature
In situ fluorine NMR imaging has been used to measure vascularity in subcutaneously implanted mammary tumors. Oxyferol, a perfluorinated blood substitute comprised of an emulsion of 25% w/v perfluorotributylamine, was used as a tracer. Following iv administration, this perfluorocarbon emulsion
Bone scintigraphy with 99mTc diphosphonates may exhibit extraosseous lesions in addition to metastatic lesions. Multiple factors can affect extraosseous 99mTc methylene diphosphonate (MDP) uptake. Similar uptake pattern of 99mTc MDP and fluorine-18 fluorodeoxyglucose (18F FDG) in hepatic metastasis
Although fluorine-18 deoxyglucose-positron emission tomography (FDG-PET) is a sensitive diagnostic modality in detecting malignant tumors, differential diagnosis of malignant tumors from inflammatory lesion is challenging. We experienced a case of acute degenerative necrosis superimposed on chronic
Phenylphthalimides (2-phenyl-1H-isoindole-1,3-diones) were prepared and their effects on tumor necrosis factor alpha (TNF-alpha) production by human leukemia cell line HL-60 stimulated with 12-O-tetradecanoylphorbol-13-acetate (TPA) were examined. An analysis of the structure-activity relationships
OBJECTIVE
To design a fluorine MRI/MR spectroscopy approach to quantify renal vascular damage after ischemia-reperfusion injury, and the therapeutic response to antithrombin nanoparticles (NPs) to protect kidney function.
METHODS
A total of 53 rats underwent 45 min of bilateral renal artery
The liver, heart, lungs, and stomach of rats exposed to hydrogen fluoride were studied. Histological examination showed partial liver necrosis and emphysema. Using histochemical methods the effect of fluorine ions was found in: a reduction of the activity of succinic and beta-hydroxybutyric
