A 72-Year-Old Woman With Multiple Pulmonary Nodules and a History of Malignancy
(2021)A 72-year-old woman, nonsmoker, presented with approximately 2 months of nonproductive cough. The cough was initially intermittent, occurred more regularly during bedtime, but gradually became more frequent throughout the ... -
Applications of nanotechnology in diagnostics and therapeutics of Alzheimer's and Parkinson's disease
(2015)In this paper, an extended review analysis has been presented concerning the developments in brain drug delivery through new and efficient applications of nanotechnology. Modern nanotechnological approaches for the diagnosis ... -
Breast Cancer Classification on Multiparametric MRI – Increased Performance of Boosting Ensemble Methods
(2022)Introduction: This study aims to assess the utility of Boosting ensemble classification methods for increasing the diagnostic performance of multiparametric Magnetic Resonance Imaging (mpMRI) radiomic models, in differentiating ... -
Characteristics and outcomes of cancer patients who develop pulmonary embolism: A cross-sectional study
(2021)Pulmonary embolism (PE), along with deep vein thrombosis, are collectively known as venous thromboembo- lism (VTE). Predisposing factors for PE include post-operative conditions, pregnancy, cancer and an advanced age; of ... -
Clinical effect of accessory renal artery coverage after endovascular repair of aneurysms in abdominal and thoracoabdominal aorta
(2021)Background: The aim of our systematic review and meta-analysis was to assess the effect of accessory renal artery (ARA) coverage on renal function in terms of acute kidney injury (AKI), renal infarction, chronic renal ... -
Comparison of physiological and post-endovascular aneurysm repair infrarenal blood flow
(2017)Endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms results in redirection of blood through the deployed endograft (EG). Even though EVAR is clinically effective, the absolute flow restoration is not warranted. ... -
Computer-based automated estimation of breast vascularity and correlation with breast cancer in DCE-MRI images
(2017)Dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) with gadolinium constitutes one of the most promising protocols for boosting up the sensitivity in breast cancer detection. The aim of this study was twofold: ... -
Conjugate eye deviation as predictor of acute cortical and subcortical ischemic brain lesions
(2016)Objectives Non-enhanced computed tomography (NECT) of the brain is used to exclude intracranial hemorrhage in patients who are considered for treatment with tissue plasminogen activator due to stroke symptoms. However, ... -
Contrast-enhanced and unenhanced diffusion-weighted imaging of the breast at 3 T
(2018)Aim: To evaluate the effect of intravenous gadolinium contrast agent on diffusion-weighted sequences and apparent diffusion coefficient (ADC) measurements at 3 T. Materials and methods: Sixty-two biopsy-proven breast lesions ... -
Contrast-induced nephropathy in an animal model: Evaluation of novel biomarkers in blood and tissue samples
(2019)Identification of novel biomarkers of contrast-induced nephropathy (CIN)that may more accurately detect renal function changes; reflect kidney damage; assist monitoring; and elucidate pathophysiology attract considerable ... -

A Giant Tarlov Cyst Presenting with Hydronephrosis in a Patient with Marfan Syndrome: A Case Report and Review of the Literature
(2019)Background: Giant Tarlov cysts are always symptomatic and mimic many serious pathologic entities. We present the largest, to our knowledge, reported Tarlov cyst. Case Description: A 33-year-old woman with Marfan syndrome ... -
Histopathological evaluation and redox assessment in blood and kidney tissues in a rabbit contrast-induced nephrotoxicity model
(2017)Contrast-induced nephropathy (CIN) is a leading cause of hospital-acquired acute kidney injury as a result of iodinated contrast-media use for diagnostic purposes. Pathophysiology remains unclear. In the present study ... -
Incorporating diffusion-weighted imaging in a diagnostic algorithm for multiparametric MR mammography
(2022)Background: Apparent diffusion coefficient (ADC) measurements are not incorporated in BI-RADS classification. Purpose: To assess the probability of malignancy of breast lesions at magnetic resonance mammography (MRM) at 3 ... -
