OBJECTIVE We undertook this meta-analysis to compare the significance of Gadolinium-enhanced MRI and 18FDG PET/PET-CT for diagnosing brain metastases of lung cancer patients. RESULTS Five articles comprising 941 patients were included for analysis. The sensitivities with 95% confidence interval for PET/PET-CT and MRI were 0.21 (0.13 - 0.32) and 0.77 (95% CI = 0.60 - 0.89), specificities were ...

INTRODUCTION High frequency repetitive transcranial magnetic stimulation (HF-rTMS) of the left dorsolateral prefrontal cortex (DLPFC) might be a promising strategy to treat depression, but not all patients show a positive outcome. OBJECTIVE In this open study, we evaluate whether a favorable HF-rTMS treatment outcome could be predicted by baseline prefrontal brain glucose metabolism (CMRglc),...

The growing availability and development of PET/CT imaging has significantly improved the work of all professionals who deal with cancer care: radiologists, clinical oncologists, radiation oncologists and surgeons. The primary use of PET/CT is diagnosis. By using radiotracer-labeled agents that are able to specifically visualize tumor cells or even certain phenomena undergoing in them, signific...

Accurate identification of viable myocardium is crucial in patient qualification for medical or surgical treatment. Only persons with confirmed cardiac viability will benefit from revascularization procedures. It is also well known, that the amount of viable myocardium assessed preoperatively is the best indicator of long term cardiac event free survival after cardiac intervention.There are sev...

Programmed cell death-ligand 1 (PD-L1) expression is commonly observed in non-small cell lung cancer (NSCLC). The prognostic value of PD-L1 expression and the maximum standardized uptake value (SUVmax) on 18F-Fluorodeoxyglucose positron emission tomography (18FDG-PET) in surgical pulmonary squamous cell carcinoma(SCC)remains unclear. Furthermore, the correlation between the SUVmax and PD-L1 exp...

Clinical oncology relies increasingly on biomedical imaging, with anatomical imaging, especially using CT and 1H-MRI, forming the mainstay of patient assessment, from diagnosis to treatment monitoring. However, the need for further improvements in specificity and sensitivity, coupled with imaging techniques that are reaching their limit of clinically attainable spatial resolution, has resulted ...

A 36-year-old woman was admitted for recurring chest pain and hemoptysis. Blood pressure in the right and left arms was equal, and no murmurs or bruits were heard. Body temperature was normal on admission and remained within the normal range during the hospital stay. C-reactive protein was slightly elevated (2.3 mg/dL) and lupus anticoagulant was positive. Angiography showed no abnormality of t...
