Computed Tomography

Cardiac computed tomography (CT) has become a primary cardiovascular imaging modality in the past 20 years, and was recommended as a 1A recommendation in the 2021 chest pain assessment guidelines. CT calcium scoring has became a primary risk assessment for coronary artery disease and whether patients should be on statins. Coronary CT angiography (CCTA) is used to for anatomical assessment of the arteries for plaque burden and to identify areas of blockage that may cause ischemia and heart attacks. Additional use of contrast CT perfusion or fractional flow reserve CT (FFR-CT) can offer physiological information on the function of the heart. CT plays a primary role in structural heart assessments for heart valves, repair of congenital defects and left atrial appendage occlusion (LAAO) for both pre-procedure planning and procedural guidance.

Is coronary heart disease on CT associated with early development of COPD?

"This awareness is important to avoid oversight of symptoms like dyspnea and vague chest discomfort, which can easily be interpreted as symptoms caused by the known disease COPD,” experts involved in the study said.

Cardiologists and surgeons perform first TAVR using CT imaging guidance on HF patient with blood clot

“We believe this case is potentially groundbreaking," one interventional cardiologist said.

Study urges radiologists to report CAC findings on all chest CTs, regardless of clinical indication

Although current guidelines recommend radiologists evaluate CAC on all non-gated, non-contrast chest CT scans, the authors of the study note that these guidelines are not consistently followed.

Statin reduces risk for non-obstructive CAD patients but no significant risk reduction for aspirin

The results of a study published in Radiology: Cardiothoracic Imaging call into question the value of initiating aspirin therapy in certain instances.

Why cardiologists and radiologists are choosing cardiac CT over invasive angiography for suspected CAD

"A CT-first strategy allows physicians to provide relevant findings without the need for an invasive procedure," one radiologist explained.

Duly Health and Care in suburban Chicago recently opened a new outpatient cardiac evaluation center equipped with a dedicated cardiac CT system, which will likely be a new business model that will be seen more in the coming years.

Leslee Shaw, PhD, and former presidents of both SCCT and ASNC discusses the role of CT and FFR-CT in the 2021 chest pain guidelines.

Leslee Shaw, PhD, director of the Blavatnik Family Women’s Health Research Institute at Mount Sinai Hospital in New York and former president of the Society of Cardiovascular Computed Tomography (SCCT) and the American Society of Nuclear Cardiology (ASNC), explains the role of cardiac computed tomography (CT) in the recent 2021 chest pain guidelines.
