Precise Liver Imaging in a 9-Year-Old

MRI of the pediatric liver poses a unique challenge: balancing spatial resolution, motion management, and scan speed. In this case, a 9-year-old patient underwent liver imaging on a 3.0T GE SIGNA Architect system using both Snuggle coils anteriorly and posteriorly. The acquisition protocol allowed for excellent tissue contrast with a short scan duration and no sedation.

Liver Imaging Parameters

• Scanner: GE SIGNA Architect (3.0T)

• Software: SIGNA_LX1.MR30.1_R01_2322.c

• Receive Coil: 24InkSpaceAP_40

• Patient Age: 9 Years

• Anatomy: Liver

Scan Settings:

• Voxel Size: 0.7 mm × 0.7 mm × 5.0 mm

• Matrix: 512 × 512 × 37

• Slice Spacing: 5.0 mm

• Flip Angle: 130°

• Echo Time (TE): 81.9 ms

• Repetition Time (TR): 1369.7 ms

• Echo Train Length: 1

• Percent Sampling: 86.4%

• Acquisition Type: 2D

Clinical Relevance

The 2D acquisition produced high signal fidelity across the hepatic field with clear differentiation of parenchyma and vasculature. A voxel size of 0.7 mm × 0.7 mm allowed detailed in-plane resolution, while a 5.0 mm slice thickness helped optimize signal-to-noise ratio across 37 slices.

The scan was completed quickly and with minimal patient movement which is clinically significant in pediatric imaging where patient tolerance and motion artifacts often limit diagnostic yield. The use of a pediatric-specific anterior coil helped maintain coil-to-body proximity and reduced variability in signal intensity.

Why the Snuggle Pediatric Coil Matters

Snuggle with its low-profile, flexible design conforms to small anatomy without compression or discomfort. For radiology teams, this translates into:

• Improved SNR from closer coil placement

• Shorter exam times due to reduced need for repositioning

• Consistent diagnostic quality across abdominal and hepatobiliary studies

• Reduced need for sedation, particularly important for abdominal studies in younger patients

This case underscores how the right coil can elevate the entire workflow—supporting both patient outcomes and operational efficiency.
