What is the typical purpose of using parallel imaging in MRI?

The typical purpose of using parallel imaging in MRI is to reduce scan time. Parallel imaging accelerates the image acquisition process by using multiple coil elements that capture data simultaneously. This technology utilizes the spatial sensitivity of the coils to reconstruct the image more quickly than traditional methods, which often leads to a significant decrease in the duration of the scan without compromising the overall image quality.

By utilizing the additional information gained from these multiple channels, parallel imaging techniques can significantly speed up data collection, allowing for faster examination of patients, enhancing patient comfort, and improving throughput in clinical settings. While other aspects of MR imaging, such as resolution, contrast enhancement, and artifact minimization, are important factors, the primary and most distinctive advantage of parallel imaging lies in its ability to reduce the amount of time required to complete an MRI scan.
