| description | High-resolution postcontrast 3D T1WI is a widely used sequence for evaluating brain metastasis, despite the long scan time. This study aimed to compare highly accelerated postcontrast 3D T1-weighted sampling perfection with application-optimized contrasts by using different flip angle evolution by using wave-controlled aliasing in parallel imaging (wave-T1-SPACE) with the commonly used standard high-resolution postcontrast 3D T1-SPACE for the evaluation of brain metastases.
Among the 387 patients who underwent postcontrast wave-T1-SPACE and standard SPACE, 56 patients with suspected brain metastases were retrospectively included. Two neuroradiologists assessed the number of enhancing lesions according to lesion size, contrast-to-noise ratio
, contrast-to-noise ratio
, contrast ratio
, and overall image quality for the 2 different sequences.
Although there was no significant difference in the evaluation of larger enhancing lesions (>5 mm) between the 2 different sequences (
= .66 for observer 1,
= .26 for observer 2), wave-T1-SPACE showed a significantly lower number of smaller enhancing lesions (5 mm) and marked scan time reduction compared with standard SPACE. However, postcontrast wave-T1-SPACE showed underestimation of smaller enhancing lesions ( |
