Lung tumor and metastatic lesion

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

Patient history

A patient with lumbar pain and left radicular pain underwent 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


CT of the lumbar spine shows an osteolytic lesion in the lumbar body L4 (rectangle). Subsequent whole body DWI confirms the metastatic lesion as a hyperintense lesion (arrow). Additionally, WB-DWI shows a b1000 hyperintense mass in the left lung, compatible with a primary lung tumor. This was confirmed by subsequent CT of the chest and bronchoscopy.

Diagnosis

CT of the lumbar spine and subsequent whole body DWI visualized a metastatic hyperintense lesion in the lumbar body L4. Whole body DWI and subsequent CT of the chest together with bronchoscopy confirmed a primary lung tumor in the left lung.

Clinical impact of using WB DWI

Thanks to its exceptional contrast-to-noise ratio and the resulting improved lesion conspicuity, diffusion-weighted MR imaging (DWI) offers additional value to conventional MRI for lesion visualization. The benefits of the technique are even more apparent at 3.0T, which enables even higher contrast-to-noise ratios.
