MR spectroscopy of 18-year-old with Aspergilloma

Case Study
Van Cauter, Sofie, M.D. University Hospitals Leuven • Belgium

Patient history

18-year-old subcomatous woman with a history of bone marrow transplant.

MR examination

The Achieva 3.0T TX was used.

MR images

Conventional MRI shows multiple diffusely enhancing lesions. MR Spectroscopy in the lesions show a high lipid peak, relatively low metabolite content though without increased Cho/NAA ratio. The findings are suggestive of inflammatory disease rather than tumor. The diagnosis was mainly based on clinical findings and conventional imaging, but it was interesting to demonstrate spectra with different features than in tumor.



Impact of 3.0T MR Spectroscopy

Spectroscopy can be of potential value in the distinction between tumors and inflammatory disease.
Applying SENSE in two directions has enabled the Leuven team to dramatically shorten the scan time of MR spectroscopic imaging (MRSI) in the brain to about three and a half minutes without loss of spectral or spatial resolution, while maintaining sufficient SNR. These shorter scan times make it practical to include MR spectroscopy in routine brain MR exams.
