psir序列是心脏磁共振 lge延迟强化 常用的序列，该序列的优点是不用计算正常心肌过0时间，通过cr能够得到比较稳定的图像。除了心脏，psir序列还可以用于颈椎扫描以提高脊髓对比度。

2024年8月28日 · Phase-sensitive inversion recovery (PSIR), also known as phase-corrected inversion recovery (PCIR), refers to an inversion recovery MRI pulse sequence that accounts …

What is phase-sensitive IR and why does it have a gray background? The sequence with the gray background you are describing is called phase-corrected or phase-sensitive inversion recovery …

Based on these advantages, T1 weighted PSIR is now being explored for the detection of MS lesions in the cervical spinal cord. The T1 weighted PSIR images can be reconstructed as a …

The T1-weighted PSIR shows great potential in revealing MS lesions in the cervical spinal cord. While using this technique it is important to use the phase sensitive reconstruction to preserve …

Phase-sensitive inversion recovery (PSIR) is a specialized technique used in magnetic resonance imaging (MRI) that enhances image quality by improving the contrast of the images. It’s …

近年来，心脏磁共振延迟强化 (late gadolinium enhanced，LGE)已被广泛应用于临床检测及评价心肌梗死，可以准确评估局部梗死心肌位置和范围，对诊断、治疗及判断预后具有重要意义。 …

2019年9月1日 · The T1 weighted PSIR image is reconstructed using (1) PSIR = ± SI 1 SI 1 + SI 2 where signal SI 1 is the short inversion time (TI 1) and signal SI 2 is the long inversion time (TI …

This study shows that in the setting of a 1.5 T magnet field, STIR significantly has a superiority over both of the PSIR reconstructions (i.e. real and magnitude) for the detection as well as the …

The T1-weighted PSIR shows great potential in revealing MS lesions in the cervical spinal cord. While using this technique it is important to use the phase sensitive reconstruction to preserve …
