Objectives: CT angiography (CTA) is gradually replacing digital subtraction angiography (DSA) in the etiologic workup of intracranial hemorrhage, though debate persists regarding its diagnostic accuracy. To better define the role of CTA in a pragmatic, real-world setting, we reviewed the experience ...
The 'Triple Rule Out" CT has recently been touted as a tool to quickly assess for life threatening causes of acute chest pain, namely acute coronary syndrome, pulmonary embolism, and aortic dissection. Initial studies suggest that this protocol is safe and compares favorably with the dedicated ...
Studies have demonstrated a high negative predictive value of CT coronary angiography (CTCA). CTCA may be reasonably used for the assessment of symptomatic patients, especially in the setting of equivocal treadmill or functional testing. Also, CTCA allows assessment of coronary bypass graft patency ...
Patient-specific tube-voltage selection at coronary CT angiography based on the combination of X-ray attenuation on scout views and body mass index: how ca... Patient-specific tube-voltage selection at coronary CT angiography based on the combination of X-ray attenuation on scout views and body...
Blood tests:In certain instances, a damaged heart muscle will trigger the release of telltale substances into your blood. Measuring the level of these substances via blood testing can help your provider understand how damaged your heart is. Other blood tests can be done to measure levels of cho...
Fundamentally, cardiac imaging is a straightforward extension of the principles underpinning stationary vessel CT angiography (CTA), though the beating heart introduces some new issues for data acquisition and processing. Although the application of mechanical helical CT for coronary imaging ...
CT Angiography for the Detection of Cerebral Vasospasm in Patients with Acute Subarachnoid Hemorrhage BACKGROUND AND PURPOSE: Digital subtraction angiography (DSA) is the standard of reference for detecting cerebral vasospasm after subarachnoid hemorrhage (... GB Anderson,R Ashforth,DE Steinke,... - ...
Besides RT-PCR, chest CT has turned out to be a helpful and fast tool in diagnosing COVID-19 pneumonia, with a moderate to high overall sensitivity of 75–88% [3], [4], [5]. However, compared to the highly specific RT-PCR, the specificity of chest CT in diagnosing COVID-19 is ...
Angiography Doctors inject a dye into a vein before you get a CT scan or MRI. The dye helps to show where the trouble is. In some cases, doctors use angiography to inject a medicine that may stop the bleeding. Radionuclide scanning ...
1. Intravascular application: This product is clinically used in urography and cardiovascular angiography in adults and children, as well as cerebral angiography, peripheral and various arteriography, venography, digital subtraction and CT enhanced scanning in adults. ...
