Multidetector computed tomography has been growing in every way possible. The test is becoming more common in clinical practice. It has breached the public consciousness and is being asked for by name. Research in the field is accelerating. The technology is improving, as is our skill at interpretation. There have been hundreds of publications on the subject over the past year. We will address three of the most important recent areas of focus.
Multidetector computed tomography has been touted as a possible 'triple rule-out' for myocardial infarction, pulmonary embolus, and aortic dissection, with an eye to improving emergency department efficiency and efficacy. A recent study has shown that, at least in low-risk patients, the triple rule-out is as safe as standard of care diagnosis, and saves considerable time and expense. Calcium scoring, hotly debated for years, has received approval from both the American Heart Association and American College of Cardiology as a screening test under certain circumstances. The 64-detector scanner has shown improvement over the 16-detector scanner.
These developments indicate that multidetector computed tomography has more uses than previously realized. They also indicate that we have much more work to do before we can claim to have fully utilized this technology.
多排螺旋计算机断层扫描（MDCT）在各方面都不断发展。该检查在临床实践中越来越常见。它已进入公众意识，甚至有人点名要求进行此项检查。该领域的研究正在加速。技术在改进，我们的解读技能也在提高。过去一年里有数百篇关于这个主题的出版物。我们将探讨近期最重要的三个重点领域。
多排螺旋计算机断层扫描被吹捧为对心肌梗死、肺栓塞和主动脉夹层的一种可能的“三联排除法”，旨在提高急诊科的效率和效能。最近一项研究表明，至少在低风险患者中，三联排除法与标准护理诊断一样安全，而且能节省大量时间和费用。多年来备受争议的钙化积分，在某些情况下已获得美国心脏协会和美国心脏病学会作为筛查测试的批准。64排探测器扫描仪相比16排探测器扫描仪有了改进。
这些进展表明，多排螺旋计算机断层扫描的用途比以前意识到的更多。这也表明，在声称已充分利用这项技术之前，我们还有很多工作要做。
