Highly-accelerated volumetric brain examination using optimized wave-CAIPI encoding.

ABSTRACT:

Background

Rapid volumetric imaging protocols could better utilize limited scanner resources.

Purpose

To develop and validate an optimized 6-minute high-resolution volumetric brain MRI examination using Wave-CAIPI encoding.

Study type

Prospective.

Population/subjects

Ten healthy subjects and 20 patients with a variety of intracranial pathologies.

Field strength/sequence

At 3 T, MPRAGE, T₂ -weighted SPACE, SPACE FLAIR, and SWI were acquired at 9-fold acceleration using Wave-CAIPI and for comparison at 2-4-fold acceleration using conventional GRAPPA.

Assessment

Extensive simulations were performed to optimize the Wave-CAIPI protocol and minimize both g-factor noise amplification and potential T₁ /T₂ blurring artifact
