Basic MRI Physics Review Questions

It seems that you're in Germany. We have a dedicated site for Germany. Cardiovascular magnetic resonance imaging CMR has become an essential part of noninvasive diagnostic cardiac imaging. A Practical Guide for Cardiovascular Magnetic Resonance Imaging provides a comprehensive and reader-friendly educational tool for physicians starting to work with CMR and cardiology and radiology trainees preparing for the Board certification examination. Appealing to trainees, this text conveys teaching points with multiple choice questions that are supported by concise comments, providing a complete explanation of the correct answer and pertinent up-to-date bibliography. Cases address a broad spectrum of clinical problems, including ischemic, valvular, myopathic, pericardial, aortic and congenital heart diseases.

MRI Technologist Interview Questions

Magnetic resonance imaging MRI is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes of the body. MRI scanners use strong magnetic fields , magnetic field gradients, and radio waves to generate images of the organs in the body. While the hazards of ionizing radiation are now well controlled in most medical contexts [ citation needed ] , an MRI may still be seen as a better choice than a CT scan. MRI is widely used in hospitals and clinics for medical diagnosis and staging and follow-up of disease without exposing the body to radiation. Risks and discomfort may be associated with MRI scans. Compared with CT scans, MRI scans typically take longer and are louder, and they usually need the subject to enter a narrow, confining tube. In addition, people with some medical implants or other non-removable metal inside the body may be unable to undergo an MRI examination safely.

Cardiovascular MRI: 150 Multiple-Choice Questions and Answers

Protons will only have a slight predilection for orientation along the main magnetic field, being continually disturbed by molecular motion. They will precess wobble around the magnetic field axis, though. The net sum of the proton magnetization will, however, point along the main magnetic field and will not appear to precess since the random precession of all the protons will cancel out. The MRI scanner can only measure magnetization perpendicular to the main magnetic field B0 , as the magnetization precesses about B0. We need to apply a radiofrequency pulse to rotate the proton magnetization so that it moves into the xy-plane - then we can measure the signal.
