Managing Advanced Disease with Efficiency
The end-to-end philosophy extends beyond primary diagnosis into the management of advanced prostate cancer. For patients with metastatic spread to the skeleton, mint Lesion includes integrated AI functionality for tumor load quantification in whole-body diffusion-weighted MRI (WB-DWI), covered by the CE mark of the device itself.
In cases of bone metastasis, manual delineation is a tedious and time-consuming process that often takes an hour or more per scan1, making it impractical for routine clinical use. Consequently, without AI support, assessment in routine practice is typically qualitative rather than volumetric.
The underlying approach to automated skeletal delineation and WB-DWI quantification has been developed and described in the peer-reviewed literature.¹ This deep learning framework is implemented in mint Lesion, where segmentation results are presented in the reading environment for review, editing and approval by the radiologist before quantitative values such as total diffusion volume are recorded.
In a retrospective single-center study of 360 patients with metastatic castration-resistant prostate cancer, image processing from import of the complete whole-body MRI study to generation of the segmentation masks was performed with a reported median computation time of 90 seconds per examination; where manual refinement by the radiologist was required, this took an additional 4 to 6 minutes per case.² In that study, radiologists reviewed the segmentation alongside additional sequences such as T1-weighted images and relative fat fraction maps before approving the delineation.²
By aligning these distinct clinical phases within a single digital environment, mint Lesion moves the diagnostic process beyond fragmented data toward a unified patient history. This integrated approach supports the clinical team in maintaining consistency from the first image to the final treatment plan, ensuring that every diagnostic contribution remains a visible and accessible part of the patient journey.
