OBJECTIVE
To evaluate the utility of the 1 Tesla (1 T) Embrace (Aspect Imaging) neonatal magnetic resonance imaging (MRI) scanner in a level III NICU.
STUDY DESIGN
Embrace brain MRI findings for 207 infants were reviewed, including 32 scans directly compared within 5 days with imaging on a 3 T Siemens Trio. Clinical MRI scan abnormalities were also compared to cranial ultrasound findings.
RESULT
Of the 207 Embrace brain MRIs, 146 (70.5%) were obtained for clinical indications and 61 (29.5%) were research cases. Abnormal findings were found in 80 scans, most commonly hemorrhage and white matter injury. Notable findings included a stroke, medullary brainstem tumor, and polymicrogyria. In the 1 T versus 3 T comparison cohort, results were discordant in only one infant with punctate foci of susceptibility noted only on the 3 T scan.
CONCLUSION
The Embrace MRI scans detected clinically relevant brain abnormalities and in a subset were clinically comparable to 3 T scans.
目的
评估 1 特斯拉（1T）Embrace（Aspect Imaging）新生儿磁共振成像（MRI）扫描仪在 3 级新生儿重症监护病房（NICU）中的应用价值。
研究设计
回顾了 207 名婴儿的 Embrace 脑部 MRI 结果，其中 32 例在 5 天内与西门子 Trio 3T 进行了直接比较。还将临床 MRI 扫描异常与头颅超声结果进行了比较。
结果
在 207 例 Embrace 脑部 MRI 中，146 例（70.5%）是出于临床指征进行的，61 例（29.5%）是研究病例。80 例扫描发现异常，最常见的是出血和白质损伤。值得注意的发现包括中风、髓质脑肿瘤和多小脑回畸形。在 1T 与 3T 对比队列中，只有一名婴儿的结果存在差异，该婴儿在 3T 扫描上仅发现点状的磁敏感灶。
结论
Embrace MRI 扫描检测到了具有临床意义的脑异常，在一部分婴儿中，与 3T 扫描具有临床可比性。
