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 ... -
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: ... -
Confluent hepatic fibrosis as the presenting imaging sign in nonadvanced alcoholic cirrhosis
(2004)Confluent hepatic fibrosis (CHF) is usually a feature of advanced cirrhosis, while occurrence in early stage compensated cirrhosis is uncommon. We report the imaging findings of masslike CHF in a patient with previously ... -
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 ... -
Full Blood Count as a Potential Predicting Factor of Contrast-Induced Nephropathy after Endovascular Aortic Aneurysm Repair
(2016)[No abstract available] -
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 ... -
A meta-analysis evaluating contrast-enhanced intraoperative ultrasound (CE-IOUS) in the context of surgery for colorectal liver metastases
(2021)Background: This study aimed to assess the outcomes of contrast-enhanced intraoperative ultrasound (CE-IOUS) for patients with colorectal liver metastases (CRLMs) undergoing surgery. Method: A thorough literature search ... -
Meta-analysis of the accuracy of contrast-enhanced ultrasound for the detection of endoleak after endovascular aneurysm repair
(2019)Objective: The purpose of this systematic review and meta-analysis was to investigate the diagnostic accuracy of contrast-enhanced ultrasound (CEUS) for detection of endoleak after endovascular aneurysm repair (EVAR). ... -
MR angiogram confirms sustained blood flow in 1,2 ICSR artery of vascularized bone grafting in scaphoid nonunion treatment
(2019)Purpose: To evaluate the functioning of 1,2 intercompartmental supraretinacular artery (ICSRA) in vascularized bone grafting (VBG) of scaphoid nonunions with avascular necrosis of proximal pole. Materials and methods: ... -
Multi-parametric MRI lesion heterogeneity biomarkers for breast cancer diagnosis
(2020)Purpose: To identify intra-lesion imaging heterogeneity biomarkers in multi-parametric Magnetic Resonance Imaging (mpMRI) for breast lesion diagnosis. Methods: Dynamic Contrast Enhanced (DCE) and Diffusion Weighted Imaging ... -
Physiology of intraluminal administration of carbon dioxide as a contrast medium
(2019)Background: Carbon dioxide (CO2) exists in nature around us. In the middle of the 20th century, the intraluminal injection of CO2 demonstrated similar results to those of Digital Subtraction Angiography (DSA) with an ... -
Use of contrast-enhanced ultrasonographic examination to evaluate health status of mammary glands of ewes at the end of a lactation period
(2018)This research communication describes the use of contrast-enhanced ultrasonographic examination (CEUS) in mammary glands of ewes for diagnosis of chronic mastitis; this is the first report of the use of this modality in ...
