OBJECTIVES This study was designed to determine the usefulness of coronary computed tomography angiography (CTA) in patients with acute chest pain. BACKGROUND Triage of chest pain patients in the emergency department remains challenging. METHODS We used an observational cohort study in chest pain patients with normal initial troponin and nonischemic(More)
The aim of the study was to assess the performance and diagnostic value of a dual energy CT approach to reduce metal artefacts in subjects with metallic implants. 31 patients were examined in the area of their metallic implants using a dual energy CT protocol (filtered 140 kVp and 100 kVp spectrum, tube current relation: 3:1). Specific post-processing was(More)
PURPOSE To determine the feasibility of computed tomography (CT)-based dynamic myocardial perfusion imaging for the detection of hemodynamically significant coronary artery stenosis, as defined with fractional flow reserve (FFR). MATERIALS AND METHODS Institutional review board approval and informed patient consent were obtained before patient enrollment(More)
OBJECTIVES Energetic extrapolation is a promising strategy to reduce metal artifacts in dual-source computed tomography (DSCT). We performed this study to systematically optimize image acquisition parameters for this approach in a hip phantom and assess its value in a clinical study. MATERIALS AND METHODS Titanium and steel hip prostheses were placed in a(More)
OBJECTIVES We conducted a systematic review and meta-analysis to determine the predictive value of findings of coronary computed tomography angiography for incident cardiovascular events. BACKGROUND Initial studies indicate a prognostic value of the technique; however, the level of evidence as well as exact independent risk estimates remain unclear. (More)
BACKGROUND Cardiac magnetic resonance (CMR) imaging permits early triage of patients presenting to the emergency department with acute chest pain but has been limited by the inability to differentiate new from old myocardial infarction. Our objective was to evaluate a CMR protocol that includes T2-weighted imaging and assessment of left ventricular wall(More)
OBJECTIVE Pericardial adipose tissue (PAT) is a pathogenic fat depot associated with coronary atherosclerosis and cardiovascular events. We hypothesized that higher PAT is associated with coronary high-risk lesions as determined by cardiac CT. METHODS We included 358 patients (38% female; median age 51 years) who were admitted to the ED with acute chest(More)
OBJECTIVE Patients at low risk for acute coronary syndrome (ACS) who present to the emergency department complaining of acute chest pain place a substantial economic burden on the U.S. health care system. Noninvasive 64-MDCT coronary angiography may facilitate their triage, and we evaluated its cost-effectiveness. MATERIALS AND METHODS A microsimulation(More)
In unresectable intrahepatic cholangiocarcinoma (ICC), systemic chemotherapy often is viewed as the only option, although efficacy is limited. Radioembolization (RE) using yttrium-90 (90Y) microspheres is an accepted therapy for patients with hepatocellular-carcinoma or metastatic liver tumors. However, there are limited data on the value of RE in patients(More)
BACKGROUND For evaluation of patients with chest pain and suspected acute coronary syndrome (ACS), consensus guidelines recommend use of a cardiac troponin cut point that corresponds to the 99 th percentile of a healthy population. Most conventional troponin methods lack sufficient precision at this low level. METHODS AND RESULTS In a cross-sectional(More)
