Retrospectively-gated cine gradient echo imaging is used for functional imaging, while velocity-encoded cine gradient echo imaging is used for flow quantification. The assessment of intra-myocardial contraction is possible using myocardial tagging pulses combined wi

These drawbacks have presented a technical challenge to MR manufacturers, leading to the development of a number of solutions, including vector-cardiogram (VCG) triggering, r

What’s Inside the Magnet and Why?signal to be encoded in three dimensions. This provides the unique ability to directly acquire cross sectional images in any orthogonal or oblique plane. The integral RF body transmitter coil generates a much smaller magnetic field that oscillates at the resonant (Larmor) frequency, causing the hydr

Specific items should be identified as being safe, unsafe or conditional using an international labelling system. Most commercially available magnets use active sh
