Magnetom Espree-Pink: A New Innovation in MRI

Hariette A.W.

There is a new innovation in the world of Magnetic Resonance Imaging. It is specially designed for breast scans and has made the entire examination more enduring and comforting due to its compact, open design that has a diameter of only 70 centimeters, while the magnet bore is 10 centimeters wider as compared to most conventional systems. This new innovation is a product of Siemens and was named Magnetom Espree-Pink. This 1.5-Tesla system is the shortest system available on the market today. With this breakthrough, patients can be positioned either feet-first or head-first and the scanner can also offer sufficient Click Here To Read More

Magnetic Resonance Imaging Notes: Respiratory and Cardiac Gating

Hariette A.W.

Respiratory Gating – the simplest method of eliminating respiratory motion artifact is to suspend respiration entirely though breath hold – respiratory gating and respiratory compensation were utilized because not all patients can hold their breath long enough to acquire adequate images Respiratory Compensation – also known as exorcist, ROPE and COPE – performed through reordered phase encoding – throughout the respiratory cycle, anterior chest wall motion is monitored with pressure transducer that surrounds patient’s chest – phase encoding steps are then reordered to decrease the intensity of respiratory motion artifacts and changes location of the motion artifacts within the data Click Here To Read More
