Biocompatible poly(iohexol) nanoparticles, prepared through cross-linking of iohexol and hexamethylene diisocyanate followed by coprecipitation the resulting cross-linked polymer with mPEG-polylactide, were utilized as contrast agents for in vivo X-ray computed tomography (CT) imaging. Compared to conventional small-molecule agents, nanoparticles exhibited substantially protracted retention within tumor bed a 36-fold increase CT 4 h post injection, which makes it possible acquire images...
The purpose of this study was to test the hypothesis that porous poly-L-lactic acid (PLLA) sensor coatings reduce fibrosis and promote blood microvessel formation in tissue adjacent surface. Porous PLLA were produced using ammonium bicarbonate as gas foaming/salt leaching agent, deployed on functional nonfunctional sensors. minimally affected accuracy response rate vitro. Three-week subcutaneous rat studies glucose sensors showed anticipated effect enhancing vascularity decreasing collagen...
Image-guided tumor ablation is an increasingly utilized tool to treat focal malignancy. Tumor can be divided into two large categories, thermal and chemical ablation. The authors provide overview of the current methods used achieve tumors, specifically addressing basic science behind as well providing a brief synopsis commercial devices currently available for use in United States.
We aimed to assess the safety, efficacy, and clinical outcomes of splenic artery embolization (SAE).A total 50 patients (male:female, 33:17; mean age, 49 years) who underwent SAEs between 1998 2011 were retrospectively studied. The procedure indications included aneurysm or pseudoaneurysm (n=15), gastric variceal hemorrhage preoperative reduction surgical blood loss (n=9), other (n=11). In total, 22 procedures elective, 28 urgent emergent. embolic agents coils (n=50), gelatin sponges...
The quantitative relationship between tumor morphology and malignant potential has not been explored in liver tumors. We designed a computer algorithm to analyze shape features of hepatocellular carcinoma (HCC) tested feasibility morphologic analysis.Cross-sectional images from 118 patients diagnosed with HCC 2007 2010 were extracted at the widest index diameter. margins outlined, point coordinates input into MATLAB (MathWorks Inc., Natick, Massachusetts, USA) algorithm. Twelve descriptors...
Purpose To assess the safety and efficacy of StarClose SE Vascular Closure System (Abbott Vascular, Abbott Park IL, USA) in high-risk thrombocytopenic coagulopathic interventional oncology (IO) patients. Methods In this single institution retrospective study, 63 or IO patients (M:F=51:12, mean age 58 years, range 31–88 years) who underwent 83 common femoral arteriotomy closures using device were identified among all (n=131) undergoing closure (n=177) between 2008–2011. High-risk...
This study investigates how quantitative texture analysis can be used to non-invasively identify novel radiogenomic correlations with clear cell renal carcinoma (ccRCC) biomarkers.The Cancer Genome Atlas-Kidney Renal Clear Cell Carcinoma open-source database was 190 sets of patient genomic data that had corresponding multiphase contrast-enhanced CT images in The Imaging Archive. 2,824 radiomic features spanning fifteen families were extracted from using a custom-built MATLAB software...
<i>Purpose:</i> Evaluate the feasibility of spectral analysis, particularly fast fourier transform (FFT), to help clinicians differentiate clear cell renal carcinoma (ccRCC) tumor grades using contrast-enhanced computed tomography (CECT) images masses, quantitatively, and compare their performance Fuhrman grading system. <i>Materials Methods:</i> Regions interest whole lesion were manually segmented co-registered from multiphase CT acquisitions 95 patients with ccRCC. Here, FFT is employed...
We report a rare case of dual arterial supply to an otherwise normal lung discovered incidentally during initial angiography performed with the intent chemoembolization hepatocellular carcinoma. In addition hepatic supply, proper artery provided systemic lower lobe left lung. Subsequent chest computed tomography demonstrated tracheobronchial tree and pulmonary Although other anatomic variants have been reported, there are no reported cases from Identifying is important while performing...

The characterization of tumors after being imaged is currently a qualitative process performed by skilled professionals. If we can aid their diagnosis identifying quantifiable features associated with tumor classification, may avoid invasive procedures such as biopsies and enhance efficiency. aim this paper to describe the 3D EdgeRunner Pipeline which characterizes shape tumor. Shape analysis relevant malignant tend be more lobular benign ones tare generally symmetrical. method described...

Characterisation of tumours on imaging is usually performed qualitatively by visual analysis radiologists. However, incorporating quantitative features would potentially increase diagnostic accuracy and improve patient care management. The goal to eventually be able distinguish certain quantifiable features, which along with qualitative ones could differentiate between benign malignant tumours. This may obviate the need for invasive procedures such as a biopsy, also allow earlier detection...
