Imaging Discussion
1
T2-weighted half-Fourier acquisition single-shot turbo spin echo (HASTE) imaging in the axial, sagittal, and coronal planes; diffusion-weighted imaging (DWI); apparent diffusion coefficient (ADC) in the axial plane; T2-weighted FLAIR in the axial plane; and gradient echo (GRE) in the axial plane is use in this case.

-
Imaging was performed on a 1.5- or 3-T MR scanner (Siemens Healthcare).
-
In this case, MRI had an even higher sensitivity and specificity for detecting all types of hemorrhage measured.
3
The procedure takes 7 minutes to complete. No sedation or patient restraints were used for imaging.
What we are looking for?
Example of intracranial hemorrhages identified on surveillance trauma MRI but not readily identifiable on an initial CT scan. Images (A, B) obtained in a 3-year-old female with TBI following crush injury. The CT (A) reveals SAH and skull fracture, prompting hospital admission and a surveillance scan. Surveillance MRI, an axial GRE sequence (B), reveals SAH, as well as EDH (short arrow) and IPH (long arrow) that had not been previously demonstrated on CT. Images (C–E) obtained in a 2-year-old female who presented with a severe TBI following a high-speed motor vehicle collision. The CT (C) reveals a scattered SAH with no other intracranial bleeds. Surveillance MRI, an axial FLAIR sequence (D), reveals areas of hyperintensity concerning for IPH (long white arrows, D)
