This program examines the physics and most recent clinical applications of gradient echo (GRE) sequences and describes how GRE differs from spin echo (SE) sequences, along with its characteristics and types of GRE sequences. By the end of this program, you should be able to: 1. Discuss how gradient echo sequences differ from spin echo

Bill Faulkner, noted magnetic resonance (MR) educator and consultant, reviews the cause, creation, and elimination of the most common artifacts produced when scanning with systems of various field strengths. After completing this program, you should be able to: 1. Identify four major categories of MR imaging artifacts. 2. Explain the

“That’s a penguin.” In this program, one of the world's leading medical physicists correlates the relationship of penguins to understanding the concepts of electrostatics, electrodynamics, magnetism, electromagnetism, electromagnetic radiation, and contrast resolution.  After completing this course, you should be

The "missile effect" refers to the capability of the fringe field component of the static magnetic field of a magnetic resonance (MR) system to attract a ferromagnetic object, drawing it rapidly into the scanner by considerable force. Obviously, the missile effect can pose a significant risk to the patient inside the MR system and anyo

A lot of technologists have never scanned on an MR system unless they were using fast spin echo, and many times this technique has been taken for granted. In fact, many people no longer refer to it as fast spin echo or turbo spin echo, they simply call it spin echo. This program reviews the development of FSE and provides an overview o

There are numerous types of artifacts that can affect a magnetic resonance (MR) image. Some artifacts influence the diagnostic quality of the image, while others may be confused with pathology.  After completing this program, you should be able to: 1. Discuss principles of magnetic fields used in magnetic resonance imaging (MRI).

This program discusses the basic principles of magnetic resonance imaging (MRI). To continue to expand your knowledge and understanding of complicated protocols and applications in MRI, it is essential to fully grasp the basic concepts of MRI physics. In this program, we cover various topics in basic MR physics, image weighting, image

The ability to read and interpret radiographs is an important aspect of critical care practice and can often help expedite appropriate intervention. More than two billion x-rays are taken around the world each year. On a regular basis, nurses care for patients who undergo this common procedure. By the end of this program, the particip

In day-to-day radiology, there are certain anatomy-related terms that you will come across that are very important, especially when it comes to positioning the patient or communicating about the site of the lesion with the concerned doctor. After completing this course, you will be able to:  • identify important anatomical la
