Tag: computed tomography angiography (CTA)

Computed tomography angiography (CTA) is being increasingly used in evaluating patients with suspected coronary artery disease (CAD) and possible angina. It is currently unclear, however, which patient subgroups in which CTA demonstrates the highest diagnostic clinical performance. In this meta-analysis, individual patient data (n=5332) from 64 prospective diagnostic accuracy...
Suicide in older adults living in or transitioning to residential long-term care, 2003 to 2015 It is estimated that by the year 2050, 1 in 5 individuals will be 65 years or older. In addition to the growing number of seniors in North America, the rate of suicide has also...
The following study summary is an excerpt from the book 2 Minute Medicine’s The Classics in Radiology: Summaries of Clinically Relevant & Recent Landmark Studies, 1e (The Classics Series). 1. In patients presenting to the emergency department with acute chest pain, evaluation with computed tomographic coronary angiography (CTCA) led to significantly...
1. In this randomized trial, diabetic patients with stable chest pain randomized to coronary computed tomographic angiography (CTA) had lower rates of cardiovascular death and myocardial infarction than those randomized to functional stress testing. 2. This benefit of the coronary CTA was not seen in nondiabetic patients. Evidence Rating Level: 1...
1. In a retrospective review of over 900 CT pulmonary angiography (CTA) studies in a single tertiary-care institution, image reinterpretation demonstrated a 25.9% discordance rate for diagnosis of pulmonary embolism (PE) from the original interpretation. 2. The most common cases of discordant diagnoses occurred in solitary segmental or subsegmental PEs...
1. Timing invariant computed tomography angiography (CTA) derived from computed tomography perfusion can reliably detect large artery occlusions in ischemic stroke, possibly reducing the need for separate CTA in the acute setting. Evidence Rating: 3 (Good) Study Rundown: Current stroke imaging research is aimed at identifying patients with acute ischemic stroke...
1. In a prospective study of 178 patients with ischemic stroke, complete reperfusion was seen in less than two thirds of patients with complete recanalization on computed tomography angiography. 2. Predictors of complete reperfusion were lower stroke severity score, lower clot burden, distal thrombus location, and small infarct and ischemic area. Evidence...
