29 Ιουλ 2014 · The purposes of this Clinician Update are to summarize the evidence on stochastic risks from diagnostic cardiovascular imaging tests involving ionizing radiation, to enable a realistic appraisal of risk, and to facilitate a rational dialog between healthcare providers and their patients.
19 Μαρ 2013 · 1. Is my test being performed for an appropriate indication according to appropriate use criteria established by professional societies, and if not, is there a good clinical reason why I’m having the test? If you’re concerned about radiation, you should ask this question of the doctor referring you for the test.
1 Αυγ 2018 · Here's some perspective on the benefits and risks. Cardiologists have many options for visualizing the heart, some of which involve exposure to radiation. Used appropriately, these tests can identify possibly life-threatening conditions, such as dangerous heart artery blockages.
2 Φεβ 2012 · In recent years, intensive efforts have been initiated to reduce the ionizing radiation associated with cardiac imaging. It is now routine for publications addressing cardiac imaging to report radiation doses, and several studies have estimated cancer risks from a variety of cardiac imaging procedures.
A cardiac computed tomography (CT ) scan uses many X-rays from different angles to construct images of your heart using a scanner and computer. This quick but detailed and high-resolution scan shows your healthcare provider problems with your heart structure, valves, arteries, aorta and more.
Assuming there is a linear, no-threshold concept of ionising radiation harm, the estimated lifetime risk of death from cancer associated with the radiation dose received during a typical coronary CT scan (ok. 10 mSv) is 0.05%.
