Beam hardening artifact reduction using dual energy computed tomography: implications for myocardial perfusion studies [PDF]

, 2015
Background: Myocardial perfusion computed tomography (CTP) using conventional single energy (SE) imaging is influenced by the presence of beam hardening artifacts (BHA), occasionally resembling perfusion defects and commonly observed at the left ...

State of the art: iterative CT reconstruction techniques [PDF]

, 2015
Owing to recent advances in computing power, iterative reconstruction (IR) algorithms have become a clinically viable option in computed tomographic (CT) imaging. Substantial evidence is accumulating about the advantages of IR algorithms over established

Computed Tomography Coronary Angiography

Journal of the American College of Cardiology, 2006
Recent developments in computed tomography technology have made imaging of the coronary arteries possible. All the same, the rapid motion and small dimensions of the coronary vessels make coronary computed tomography angiography (coronary CTA) challenging.

Unusual case of single coronary artery with anomalous RCA from LAD: The ultimate of cardiac CT

IHJ Cardiovascular Case Reports, 2021
Coronary artery anomalies are found in 0.6%–1.55% of patients who undergo coronary angiography, and the increasing use of diagnostic coronary angiography is unveiling even more complex coronary anomalies.

Prognostic durability of coronary computed tomography angiography

European Heart Journal - Cardiovascular Imaging, 2020
Abstract Aims  This large prospective cohort study sought to confirm the incremental prognostic value of coronary computed tomographic angiography (CCTA) measured over a prolonged follow-up duration. CCTA has diagnostic and prognostic value but data supporting its long-term prognostic value in a large

Left Main Coronary Artery Thrombus Diagnosed and Managed With Coronary Computed Tomography Angiography and Fractional Flow Reserve Derived From Computed Tomography

Clinical Medicine Insights: Cardiology, 2019
Left main coronary artery thrombus (LMCA-T) is a rare disease state and diagnosed with invasive coronary angiography (ICA). We present a case of LMCA-T diagnosed with coronary computed tomography angiography (CTA) and treated without ICA in a patient who

Impact of incomplete ventricular coverage on diagnostic performance of myocardial perfusion imaging. [PDF]

, 2017
In the context of myocardial perfusion imaging (MPI) with cardiac magnetic resonance (CMR), there is ongoing debate on the merits of using technically complex acquisition methods to achieve whole-heart spatial coverage, rather than conventional 3-slice ...
