Is body and cardiovascular imaging at 3T superior to 1.5T or is
3T advantageous for only certain indications? Basic principles of 3T
technology will be reviewed and the potential benefits and challenges of
3T explored. It will be discussed how 3T imaging may impact patients,
radiologists and technologists with regard to safety, workflow,
protocols and image quality.
Upon completion of this session, participants should be able to:
• Describe the basic physics of imaging at 3T and its effects on signal
to noise, relaxation rates, susceptibility, chemical shift, power
deposition, and patient safety;
• List advantages and disadvantages of Body and cardiovascular imaging
at 1.5 and 3T;
• Explain why protocols optimized for 1.5T may not be optimal for 3.0T;
• Recognize the sequence parameters that may need adjusting to optimize
protocols at 3T, and discuss specifically which sequences may or may not
improve at 3T.
