Dynamic enhanced MRA sequences of the mesenteric arteries are performed using:

Dynamic enhanced magnetic resonance angiography (MRA) sequences of the mesenteric arteries are typically performed using incoherent gradient echo techniques. Incoherent gradient echo methods are adept at capturing rapid changes in signal intensity, which is particularly important in dynamic imaging where the distribution of contrast material is being monitored.

These techniques can take advantage of time-resolved imaging, allowing the visualization of blood flow dynamics and enhancing the contrast between the vascular structures and surrounding tissues. The ability to achieve high temporal resolution is crucial in dynamic imaging applications such as MRA, where real-time assessment of blood flow is necessary.

In contrast, while coherent gradient echo techniques are useful in certain applications, they can be more sensitive to magnetic susceptibility artifacts and may not provide the same temporal resolution as incoherent methods in the context of bolus tracking during dynamic MRA. Steady-state gradient echo techniques offer certain advantages in assessing static structures but may not be as effective in dynamic angiography. T2* gradient echo sequences, although informative in specific scenarios, are not the primary choice for dynamic contrast-enhanced MRA of the mesenteric arteries due to their reliance on T2* contrast mechanisms rather than the rapid temporal sampling needed for this purpose.
