Does mri have good temporal resolution

Abstract. In fMRI, images can be collected in a very short time; therefore, high temporal resolution is possible in principle. However, the temporal resolution is limited by a blurred intrinsic hemodynamic response and a finite signal-to-noise ratio.

What is temporal resolution in MRI?

Temporal resolution is the time to take the multiple measurements of the cross-section and then reconstruct the image. This time is important for process tomography systems, as often changes can occur within the system in a space of time that is shorter than the one required to record the measurements.

Does MRI have good spatial resolution?

For a similar SNR value, scanners with a high value of B0 and a high number of coil receiver channels will produce images with higher spatial resolution and contrast (6). Nowadays, most MRI scanners used for medical purposes have B0 values of 1.5 or 3 T and can reach typical resolutions of around 1.5×1.5×4 mm3.

Which brain scan has the best temporal resolution?

EEG has an excellent temporal resolution of only a fraction of a millisecond enabling brain activity to be recorded in real-time.

Does fMRI have good temporal or spatial resolution?

Every student in psychology or neuroscience should be able to tell you that fMRI has good spatial resolution (as above), but poor temporal resolution. This is because the haemodynamic response imposes a fundamental limit on the time-precision of the measurement.
