The heart scan is a computed tomography (CT) scan of the heart that uses x-rays to create detailed pictures of the heart and its blood vessels. It is a rapid assessment tool for identifying haemodynamically significant cardiac abnormalities in the critical care setting. Specifically, physicians use heart scans to look for calcium deposits in the coronary arteries that can narrow arteries and increase the risk of heart attack.〔(【引用サイトリンク】url=http://www.mayoclinic.org/tests-procedures/heart-scan/basics/definition/prc-20015000 )〕 It is similar to the Focused assessment with sonography for trauma scan in concept, although it is directed at the heart rather than the abdomen. Often called a coronary calcium scan, it provides a score that can be used to determine the risk of a coronary event. Unlike an EKG (which would mostly show the results of past heart attacks) and Thallium Stress Test (which only shows up advanced blockages of 70% or more), the heart scan is an excellent way to determine if a person has Coronary Arterial Disease. ==Aims== The aims of the heart scan are to: * detect cardiovascular disease * assess haemodynamic status (e.g. hypovolaemia) * assess Heart valve lesions * assess Pericardial effusion 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「HEART scan」の詳細全文を読む スポンサード リンク
