CT coronary angiography for the interventional cardiologist

Atherosclerotic coronary artery disease (CAD) remains the leading cause of death in the UK. As part of the National Service Framework for Coronary Heart Disease introduced in 2000, rapid access clinics have been set up for early diagnosis and treatment of cardiac chest pain. While invasive coronary angiography (ICA) remains the gold standard for the […]

Clinical applications of SPECT/CT

SPECT/CT has established itself as a powerful diagnostic tool in nuclear medicine. The combined advantages of high sensitivity SPECT imaging with high specificity CT imaging has been shown to be superior to planar and SPECT imaging for many clinical indications. The CT component of SPECT/CT improves image quality through attenuation correction (AC), precise anatomical localisation […]

Coronary computed tomography angiography – getting the basics right

Coronary computed tomography angiography (CCTA) is a non-invasive cardiovascular imaging modality that provides isotropic resolution of the coronary arteries and associated cardiac anatomy. The new generation of state-of-the-art cardiac-enabled CT scanners offers sub-millimetre spatial resolution of the coronary vasculature, allowing clinicians to detect the presence of coronary artery plaque with high sensitivity. The National Institute […]

Functional assessment of coronary artery disease by cardiac computed tomography

Computed tomography coronary angiography (CTCA) has become an established non-invasive test for the detection of coronary artery disease (CAD). Recently, outcome data and insights into the diagnosis and management of patients with stable chest pain have been provided by two important clinical trials, The Prospective Multicenter Imaging Study for Evaluation of Chest Pain (PROMISE) and […]

CT in ischaemic cardiac disease

Coronary artery disease (CAD) remains the leading cause of death in western nations. Multi-detector CT (MDCT) images obtained with ECG gating are superior to the standard (non-ECGgated) studies due to reduction in blurring secondary to cardiac and respiratory motion, and deliver fast volume coverage and high spatial and temporal resolution. It is recognised as an […]

The prognostic value of stress echocardiography among patients with coronary artery disease

Stress echocardiography (SE) was first proposed as a non invasive clinical tool for coronary artery disease diagnosis and risk stratification in 1979. Since then, there have been over 7,000 publications validating the use of SE in the management of patients with coronary disease, valve disease, heart failure and cardiomyopathy. This article will focus on the […]

Coronary artery CT in the emergency department

Chest pain is an extremely common symptom and results in around 700,000 (5%) presentations to the emergency department (ED) in England and Wales and accounts for 25% of hospital admissions. However, only a minority of these patients (8%) actually have acute coronary syndrome (ACS), which is the umbrella term for acute chest pain due to […]

Imaging the coronary arteries with CT

In the 1980s CT imaging of coronary arteries began after the introduction of electron beam CT (EBCT), with the main application being quantification of calcifications in the coronary arteries for risk stratification. In the late 1990s helical multidetector row CT (MDCT), starting with the four-detector row, was used for noninvasive evaluation of suspected coronary artery […]
