Suspected neuro-endocrine tumor

Case Study
Vandecaveye, Vincent, M.D., Ph.D. Leuven, University of Leuven

Patient history

A patient with suspected neuro-endocrine tumor underwent PET, CT and whole body diffusion-weighted MRI on the Achieva 3.0T TX at University Hospital Leuven, Belgium.

MR examination

The MR examination on the Achieva 3.0T TX with MultiTransmit comprises a fast whole-body anatomical scan (which serves for DWIBS planning) and a single free-breathing whole-body DWI scan at b-values of 0 and 1000, optimized for visualizing lymph node, liver and skeletal/soft-tissue lesions. The exam takes only 20 minutes. The Integrated Body coil was used.

Images


DOTATOC PET and co-registered CT show a metastatic lesion in the left thoracic inlet (arrow) and a tumoral mass in the mesenterium (rectangle). Whole body diffusion-weighted MRI confirms the presence of the thoracic metastatic mass (arrow) and mesenterial mass (rectangle). Additional small peritoneal metastases are depicted as b1000 hyperintense lesions over the liver dome and right lateral hypochondriac area (arrowheads).

Diagnosis

DWIBS (whole body diffusion-weighted MR imaging) visualized the thoracic metastatic mass and mesenterial mass, as well as lesions over the liver dome and right lateral hypochondriac area inthis patient with suspected neuro-endocrine tumor. Lesions were confirmed during imaging follow-up.

Clinical impact of 3.0T DWIBS

3.0T DWIBS vsualized the same lesions as seen on the PET and C images, and in addition helped visualize lesions over the liver dome that were not visible on PET and CT.
