Brain

Cor T2w for hippocampus

Example of a high-resolution image of the hippocampus using Precise IQ Engine (PIQE). The original image is 256 matrix with low resolution and high signal-to-noise ratio (SNR). Even though the scan time is reasonably short and the slice thickness is as thin as 2 mm, the image is clear and demonstrates good contrast.

Brain

Sag T2w for pituitary

Using a regular head and neck coil, with a collection matrix 256 × 256 setting, imaging can be performed in approximately 1 minute. Structures around the pituitary gland are clearly visible. Acquisition time: 1:08

Axi T2w for orbit

Orbit image. Did not require a dedicated coil such as a circle coil to image the orbit. The image can be acquired in only 30 seconds using a normal head/neck coil with a small field of view (FOV) and low resolution. The structures around the lens are clearly visible. Acquisition time: 0:36

Axi T2w for Brain

As this case is acquired with a 3T system, increasing the matrix over 512 × 512 will result in poor SNR and reduced contrast. PIQE was applied after reducing the matrix to improve SNR and further shortening the scanning time. As a result, scan time was reduced by 53% while still achieving high resolution.

MSK

Axial FS PDw for median nerve

Using a 16ch Flex SPEEDER Medium coil and an acquisition matrix 320 × 320 setting, imaging can be performed in approximately 3 minutes. Structures around the median nerve can be clearly identified. Acquisition time: 3:14

MSK

Coronal PDw for Knee

Traditionally it has taken a long time to obtain higher resolution images in the MSK region. With PIQE, higher resolution images can be obtained in a realistic amount of acquisition time. PIQE clearly delineates the fine structures around cartilage and meniscus.

Spine

Sagittal T2w for c spine

The original image is a 288 matrix with a 3 mm slice thickness and relatively low resolution, resulting in high SNR. PIQE reconstruction can acquire high quality images within acceptable scan times.
