Computed tomographic (CT) colonography is a noninvasive option in screening for colorectal cancer. However, its accuracy as tool asymptomatic adults has not been well defined.
PURPOSE: To determine the sensitivity and specificity of computed tomographic (CT) colonography for colorectal polyp cancer detection by using colonoscopy as reference standard. MATERIALS AND METHODS: Three hundred patients underwent CT followed standard colonoscopy. Bowel preparation consisted magnesium citrate polyethylene glycol. After colonic air insufflation, scanning in supine prone positions with 3-mm collimation during a single breath hold. The transverse images, sagittal coronal...

We developed a novel computer-aided detection (CAD) algorithm called the surface normal overlap method that we applied to colonic polyp and lung nodule in helical computed tomography (CT) images. demonstrate some of theoretical aspects this using statistical shape model. The was then optimized on simulated CT data evaluated per-lesion cross-validation 8 colonography datasets chest datasets. It is able achieve 100% sensitivity for polyps 10 mm larger at 7.0 false positives (FPs)/dataset 90%...
Although recognition and curative treatment of both precursor adenomas localized cancers are possible through early-detection, regular screening reduces mortality from colorectal cancer, is largely underused. Reasons for underuse include performance drawbacks issues comfort, availability, expense. Computed tomographic (CT) colonography an alternative that provides minimally invasive, structural evaluation the entire colorectum, permits rapid imaging colorectum without sedation, with few...
Background: Colon screening by optical colonoscopy (OC) or computed tomographic colonography (CTC) requires a laxative bowel preparation, which inhibits participation. Objective: To assess the performance of detecting adenomas 6 mm larger and patient experience laxative-free, computer-aided CTC. Design: Prospective test comparison laxative-free CTC OC. The included electronic cleansing detection. Optical examinations were initially blinded to results, subsequently revealed during colonoscope...
There is limited clinical patient data comparing the first and second waves of coronavirus disease 2019 (COVID-19) in United States effects a COVID-19 resurgence on different age, racial ethnic groups. We compared Bronx, New York, among racially ethnically diverse population.Patients this retrospective cohort study were included if they had laboratory-confirmed SARS-CoV-2 infection by real-time PCR test nasopharyngeal swab specimen detected between March 11, 2020, January 21, 2021. Main...
Background Acute neurological manifestation is a common complication of acute Coronavirus Disease 2019 (COVID-19) disease. This retrospective cohort study investigated the 3-year outcomes patients with and without significant manifestations during initial COVID-19 hospitalization. Methods findings Patients hospitalized for Severe Respiratory Syndrome 2 (SARS-CoV-2) infection between 03/01/2020 4/16/2020 in Montefiore Health System Bronx, an epicenter early pandemic, were included. Follow-up...
To evaluate prospectively the prevalence of incidental extracolonic findings at computed tomographic (CT) colonography and to estimate cost their imaging work-up in male patients with high those average risk colorectal cancer.This study was approved by institutional review board, informed consent obtained from all patients. The compliant requirements Health Insurance Portability Accountability Act. CT performed 500 men (mean age, 62.5 years). Of these patients, 194 (38.8%) were for cancer...
Adenomatous polyps in the colon are believed to be precursor colorectal carcinoma, second leading cause of cancer deaths United States. In this paper, we propose a new method for computer-aided detection computed tomography (CT) colonography (virtual colonoscopy), technique which imaged along wall air-inflated, cleansed with X-ray CT. Initial work computer aided has shown high sensitivity, but at cost too many false positives. We present statistical approach that uses support vector machines...
To compare colonic distention, adequacy of preparation, and colorectal polyp detection as assessed with supine prone scanning separately in combination at computed tomographic (CT) colonography.CT colonography colonoscopy were performed 182 patients. Distention preparation eight segments rated on a scale 1-4 (1, segment completely distended or no residual material; 4, collapsed large amounts material). The data compared regard to each position alone then combination. CT findings correlated...
The purpose of this study was to estimate the ratio cancers prevented induced (benefit-risk ratio) for CT colonography (CTC) screening every 5 years from age 50 80 years.Radiation-related cancer risk estimated using projection models based on National Research Council's Biological Effects Ionizing Radiation (BEIR) VII Committee's report and protocols American College Radiology Imaging Network's Colonography Trial. Uncertainty intervals were Monte Carlo simulation methods. Comparative...
