How does spatial resolution increase in MRI?
The FOV is the size of the area that the matrix of phase and frequency encoding cover. Dividing the FOV by the matrix size gives you the in-plane voxel size; hence, increasing the FOV in either direction increases the size of the voxels and decreases the resolution. Decreasing the FOV improves the resolution.Click to see…

Spatial resolution determines how “sharp” the image looks. In MRI, spatial resolution is defined by the size of the imaging voxels. Since voxels are three dimensional rectangular solids, the resolution is frequently different in the three different directions.Furthermore, why are MRI pixels large? In MRI the resolution is determined by the number of pixels in a specified FOV. The higher the image resolution, the better the small pathologies can be diagnosed. Resolution is directly proportional to the number of pixels (The higher the number of pixels the greater the resolution). does MRI have high spatial resolution? High field MRI systems, such as 7 Tesla (T) scanners, can deliver higher signal to noise ratio (SNR) than lower field scanners and thus allow for the acquisition of data with higher spatial resolution, which is often demanded by users in the fields of clinical and neuroscientific imaging.How can I improve image quality in MRI? Increasing the matrix size: Increases spatial resolution. Decreases signal. Increases scan time. To improve the SNR: Increase NEX. Lower resolution. Thicker slices. Larger FOV. Use surface coils.
