Wykład prof. Roberta Edelmana - streszczenie

Rapid technological advances are occurring in the fields of magnetic resonance imaging (MRI) and computed tomography (CT). These advances are proving especially beneficial for cardiac imaging. With MRI, parallel imaging techniques allow scan times to be reduced by factors as

large as four or greater. Real-time MR imaging makes it practical to obtain diagnostic images even in patients with irregular heart beats. With CT, 64 slice multi-detector CT (MDCT) systems enable the
acquisition of diagnostic coronary angiograms on a routine basis. Dual-source MDCT further improves temporal resolution by a factor of two, largely eliminating the need for beta blockers to slow the heart rate.

In this lecture, current clinical applications of MRI and MDCT for the heart will be reviewed. These include the evaluation of myocardial function, perfusion, viability, pulmonary vein mapping, and coronary artery imaging. Newer developments will also be considered, such as 3 Tesla and novel contrast agents.
