Pulse Radiology MRI Live Registry Prep - April 3, 2022

Webinar Description Date: Sunday, April 3, 2022 Time: 11:00am - 3:30pm Section 1: Define T1, T2 and Proton Density, Q+A Defining TR, TE, Flip Angle, ETL and TI How do Intrinsic scan parameters affect image contrast? The Image Contrast and Image Quality Triangles, Q+A Extrinsic (Geometric) Scan Factor and their effects on SNR/Resolution. (60 mins) Section 2: Field of View, Slice Thickness Receiver Bandwidth: Wide vs. Narrow Receiver Bandwidth Scan Matrix (Phase and Frequency): Pixels vs. Voxels NEX / NSA / Concatenations. MR Math: Pixel size, Voxel size and volume, Larmor equation, SNR, Q+A Pulse Sequence design (PSD): (60 mins) Section 3: Spin-Echo vs. Gradient Echo Fast Spin Echo STIR, FLAIR and Fat-Sat Time of Flight (Flow Related Enhancement) Diffusion Weighting Images. MRI Scan time Formulas, Q+A Artifacts: Causes and Correction (60 mins) Section 4: Motion, RF, Wrap, Chemical Shift (1st and 2nd kind), Crosstalk/Excitation, Gradient Warp, Magnetic Susceptibility, Metal, Herring Bone, Annefact. Q+A Post-Test Webinar Objectives At the conclusion of the course, the participants should be able to: Understand the definitions of T1 and T2 relaxation (Intrinsic Tissue Parameters), TR, TE, Flip Angle, TI and ETL (Intrinsic Scan Parameters) affect image contrast. The concepts of the “Image Quality Triangle”, and the “Image Weighting Triangle” will be explained. The Technologist will better understand the various Geometric scan parameters and their effects on Signal to Noise, and Resolution. The student will better understand the structure of the various “line Diagrams” or PSDs, the order of events in a sequence and what makes each sequence unique. In addition, the attendee will have a better understanding and be able to perform/solve the various “math” problems that may be asked during advanced certification exams. At the end of this section, the participant will better understand the cause and corrections of artifacts commonly seen in everyday MR scanning.
