Radiation Dose Concerns in Cardiac Computed Tomography Computed tomography (CT) utilisation for general medical imaging and for dedicated cardiac indications has come under a great deal of scrutiny in the past few years.1–3 Concern has arisen due to both the increased utilisation of CT, with more than 70 million scans performed in the US in 2007, and the increasing radiation dose. A recent… View more

Over the last few decades, the rapid development of cardiac computed tomography (CT) has been unequalled by any other imaging technique. The driving forces behind cardiac multidetector-row CT (MDCT) are the enormous socioeconomic relevance of coronary artery disease (CAD) and the need for comprehensive, reliable and reproducible diagnostic tests that overcome the morbidity and mortality of… View more

Since the introduction of multislice computed tomography (MSCT) in 1998, non-invasive cardiac imaging has developed rapidly. In the recent past, two different objectives can be observed in the technological development of cardiac MSCT. On the one hand, the number of detector rows was increased up to 320 in single-source scanners in order to ensure simultaneous coverage of the entire heart with a… View more

During the last few decades, the endovascular repair of aortic aneurysms (EVAR) has revolutionised the treatment of thoracic and abdominal aortic aneurysms. Since 1991, when Parodi et al.1 reported the first series of successful endovascular abdominal aneurysm repair in humans, enormous developments have been accomplished in techniques, materials and equipment. More delicate techniques and… View more

Myocardial perfusion imaging (MPI) using combined computed tomography (CT) and single-photon emission CT (SPECT) systems plays an important role in the management of patients with coronary artery disease (CAD).1–4 The method can be used to assess myocardial perfusion and left ventricular function simultaneously. It is an especially valuable tool for assessing short-term risk of CAD, thus… View more

Coronary artery disease (CAD) represents a relevant economic burden to modern medicine. In 2003 more than 1.41 million diagnostic coronary angiograms and an additional 1.24 million percutaneous coronary angioplasties were performed in the US alone.1 While coronary angiography is considered the gold standard for diagnosing CAD, several non-invasive techniques have been evaluated for assessing CAD… View more

Contrast-enhanced magnetic resonance angiography (ce-MRA) has become an established and routinely used imaging modality and has largely replaced invasive diagnostic digital subtraction angiography (DSA). There have been ongoing technical developments in magnetic gradient hardware, coil design and pulse sequence design for ce-MRA, resulting in an increased spatial and temporal resolution. The… View more
