A Fast Method for Obtaining a “Continuous” Sample of the Inversion-Recovery Curve Using Spatially Swept Adiabatic Inversion

The measure of the longitudinal, or T, , relaxation time in nuclear magnetic resonance experiments is a common diagnostic tool. There have been several methods proposed for measuring this parameter. Most of these methods measure the recovery of longitudinal magnetization after inversion or saturation. Conventional ( 180”-Ti90”) experiments measure the signal strength for a single temporal point...

A method for 2-dimensional inversion of gravity data

Applying 2D algorithms for inverting the potential field data is more useful and efficient than their 3D counterparts, whenever the geologic situation permits. This is because the computation time is less and modeling the subsurface is easier. In this paper we present a 2D inversion algorithm for interpreting gravity data by employing a set of constraints including minimum distance, smoothness,...

The effect of inversion times on the minimum signal intensity of the contrast agent concentration using inversion recovery t1-weighted fast imaging sequence

  Background :Inversion recovery (IR) pulse sequences can generate T1-weighted images with a different range of inversion time (TI) to suppress or null the signal intensity (SI) for a specified tissue. In this study, we aimed to investigate the effect of TI values on the concentration of the contrast agent, which leads to a minimum signal intensity, using an inversion recovery T1-weighted 3-dim...

A Simple, Artistic and Efficient Modification of the Inversion Method

     The simplest and fastest way of producing an acceptable and accurate cast is by adopting the two-pour or inversion method. This process is slightly cumbersome and messy due to difficulty of access. A much more efficient, easy and artistic way of accomplishing it is described by adopting a Rotating Cake Icing Table with a Silicone Baking Mat on top as an autoclavable non-stick barrier.

Spectral Adiabatic Inversion Recovery (SPAIR) MR imaging of the Abdomen

Magnetic resonance imaging (MRI) has become a major imaging tool for the depiction and characterization of abdominal disease. Standard abdominal MRI protocols encompass different forms of T1-weighted (T1w) and T2-weighted (T2w) data acquisition. These sequences can be collected in less than 20 seconds, which typically is within the patients’ ability to suspend respiration. Hence, artifacts due ...
