The overall increase in patient irradiation caused by the growing use of spiral- and multidetector-row computed tomography (MDCT) is of particular relevance for thoracic imaging. The number of clinical indications for thoracic CT has steadily increased, and CT has become a first-line imaging tool for diseases previously imaged with chest radiography, ventilation/perfusion scintigraphy and…

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…

In this video we asked, Dr Joshua Mitchell, Assistant Professor of Medicine at Washington University School of Medicine and the Director of our Cardio-Oncology Centre Of Excellence, to summarise the topic of radiation induced heart disease. Dr Mitchell's clinical interests include cardiotoxicity from cancer therapy and cancer survivorship.

Digital medical imaging has progressed immensely in recent years, providing the opportunity to store images in a picture archiving and communications system (PACS) and eliminating the need for film storage. Images can be viewed simultaneously in many monitors during or after the radiological technique, enabling more accurate and efficient treatment of the patient. The result is acceleration of…

Sources of Radiation Exposure
Radiation used in medical examinations and tests is the largest man-made source of radiation exposure. The biological effects of the radiation dose received is expressed in milliSievert (mSv), with the effective dose of 1 mSv corresponding to the radiation dose of 50 chest X-rays. An average of 2.4 mSv per head per year comes from natural sources (see Figure 1).1…

In the clinical management of patients with complex congenital heart disease (CHD), accurate 3D evaluation of their morphological conditions is critical. 3D imaging should demonstrate the shape and spatial relation of great arteries, proximal branch pulmonary arteries and anomalous pulmonary venous or systemic connections, and eventually coronary artery course. 3D information on extra-cardiac…

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…
