SWI MRI in 47 Seconds: 68% Less Scan Time with SwiftMR

What if you could acquire SWI in just 47 seconds instead of 2 minutes and 27 seconds—and generate a super-resolution minIP from the same acquisition?

In this week’s Image of the Week, we showcase how SwiftMR® combines accelerated susceptibility-weighted imaging (SWI) with AI-powered image enhancement and automated super-resolution minIP generation.

On a 3T Siemens MAGNETOM Skyra, an accelerated SWI sequence was acquired in just 47 seconds, compared with 2:27 for the routine sequence.

That’s a 68% reduction in SWI acquisition time, with additional image enhancements through SwiftMR.

From 2:27 to 0:47: Accelerating SWI with SwiftMR

Susceptibility-weighted imaging is an important component of neuroimaging, providing sensitivity to venous structures, blood products, and other susceptibility-related findings.

However, SWI acquisition requires balancing spatial resolution, signal quality, and scan time.

In this example, an accelerated acquisition paired with SwiftMR demonstrates how MRI teams can reduce acquisition time while using deep learning reconstruction to enhance the resulting images.

Acquisition and reconstruction details

Parameter Routine SWI Accelerated SWI + SwiftMR
Scanner Siemens Skyra 3T Siemens Skyra 3T
Acquisition time 2:27 0:47
Acquired resolution 0.93 × 1.3 × 2 mm 0.93 × 1.3 × 2 mm
Reconstructed resolution — 0.23 × 0.23 × 2 mm
Time savings — 68%

Beyond Acceleration: Super-Resolution SWI and minIP

Reducing acquisition time is only part of what SwiftMR delivers.

Following acquisition, SwiftMR applies deep learning reconstruction to reduce image noise and enhance spatial resolution.

In this case, SwiftMR reconstructed the SWI images from an acquired resolution of 0.93 × 1.3 × 2 mm to 0.23 × 0.23 × 2 mm, providing a finer in-plane reconstruction.

SwiftMR also generated a super-resolution minimum-intensity projection (minIP) from the enhanced image series.
