Aug 28, 2024 · CSF flow studies are performed using a variety of MRI techniques and are able to qualitatively assess and quantify pulsatile CSF flow. The most common technique used is time-resolved 2D phase-contrast MRI with velocity encoding.

What is the difference between laminar flow, turbulent flow, and vortex flow? How can you predict whether a certain vessel will be bright or dark on an MR image? What are time-of-flight effects?

Explore Cardiac MRI flow quantification protocols, techniques, positioning, and indications for pulmonary and aortic flow MRI.

A cerebrospinal fluid (CSF) flow MRI is a specialized type of MRI scan used to visualize the flow of cerebrospinal fluid within the brain and spinal canal. In a CSF flow MRI, the goal is to assess the dynamics of this fluid to ensure it is moving properly throughout the brain and spinal column.

Please explain how flow compensation (gradient-moment nulling) software works. The idea of adjusting the waveforms of imaging gradients to correct for flow-related dephasing was first implemented by Picker scientist Fred Pattany working at Wake Forest in the late 1980's.

PC-MRI is a useful technique to evaluate CSF flow inside the spinal cord because the pulsatile, altered flow inside syrinx cavities is detected. Systolic and diastolic CSF velocities are increased in patients with poor clinical condition and in patients with large cysts.

CSF Fluid Flow MRI detects back and forth flow of Cerebrospinal fluid that corresponds to vascular pulsations from mostly the cardiac cycle of the choroid plexus.

How accurate are MR methods to measure flow? What are the artifacts and pitfalls? What is the 4th dimension in 4D Flow imaging?

This review describes recently developed advanced MRI flow techniques, which allow for more comprehensive evaluation of blood flow characteristics, such as real-time flow imaging, 2D multiple-venc phase contrast MRI, four-dimensional (4D) flow MRI, quantification of complex haemodynamic properties, and highly accelerated flow imaging.

Mar 22, 2019 · This article reviews the main technical issues of 4D flow MRI and the different parameters provided by it and describes the main applications in cardiovascular diseases, including congenital heart disease, cardiac valvular disease, aortic disease, and …
