Abnormal enhancing foci in 7-year-old

Case Study
Miller, Jeffrey, M.D. Phoenix Children's Hospital • USA

Patient history

A 7-year-old male with seizures was examined on Ingenia 3.0T at Phoenix Children's Hospital. 

MR examination

Ingenia 3.0T was used. The exam used sequences with very high resolution to help delineate small abnormalities and subtle changes. With the 3.0T field strength and the increased SNR on Ingenia, our standard brain MRI now consists of very high resolution 1 mm 3D volumetric T1 imaging and no gap 2 mm axial T2 imaging. This higher resolution imaging has enabled us to better delineate small abnormalities and detect subtle changes such as abnormal gray/white matter.

Diagnosis

MRI shows small focal T2 hyperintense and contrast-enhancing foci (white arrow).
The exact location of this abnormality is difficult to discern on FDG PET-CT.
Fusion of the PET and contrast-enhanced MR images allows precise localization of the lesion (white arrow).

Impact of using Ingenia 3.0T

Higher resolution imaging enables better delineating small abnormalities and detect subtle changes such as abnormal gray/white matter differentiation in cases of potential cortical malformations in patients with epilepsy. The 3D T1 postcontrast at 1 mm resolution reconstructed enables to have a higher sensitivity for small contrast-enhancing abnormalities.

 

By using 3D acquisitions, we’re able to reconstruct additional planes of view and thus save scan time. And we are increasingly utilizing these 3D data sets for fusion with metabolic imaging such as PET and SPECT.
