PET/CT CANCER MAPPING
See where the disease is — and measure it.
Ingensia software processes whole-body FDG PET/CT, identifies and outlines disease burden, and turns each case into measurements physicians and researchers can use. That includes tumor volume, radiomics features, and a structured report — with no manual contouring.
Simple workflow
WHAT THE SOFTWARE DOES
Left: the PET/CT scan.Right: the segmentation mask generated by the software.
The PET/CT image shows the scan with abnormal uptake in context. The segmentation image shows what the model has isolated as disease. Once that mask is created, the rest of the pipeline can measure tumor burden and export structured case-level results automatically.

ABOUT THE FOUNDER
Built by a clinical oncologist with deep AI roots
Ingensia was founded by Jacob Shreve, MD, MS, a physician–computer scientist whose career spans clinical oncology, bioinformatics, and translational artificial intelligence. The company reflects the same philosophy that has shaped his work: use advanced models where they solve real problems, validate them rigorously, and make them useful inside real clinical environments.
Professional biography
Dr. Shreve is a clinical oncologist and physician–computer scientist whose work sits at the intersection of cancer care, medical imaging, computer vision, and translational AI. He began his career in computational science and bioinformatics before moving into medicine to bring advanced analytics closer to patient care.
His postgraduate medical training includes residency at Cleveland Clinic and fellowship at Mayo Clinic. At Mayo Clinic, he founded the Hematology AI Group and helped spearhead some of the institution’s earlier practical uses of AI in hematology and oncology. That combination of technical depth and frontline clinical experience now defines Ingensia’s approach to PET/CT imaging AI: rigorous, practical, and built for the realities of real-world oncology data.
The result is a clinician-led company with a deliberately grounded style. The emphasis is not novelty for its own sake, but robust segmentation quality, transparent outputs, radiomics that can be inspected and exported, and tools that are genuinely useful for collaborating investigators and clinical teams.

Clinical training
Residency at Cleveland Clinic and hematology/oncology fellowship at Mayo Clinic anchor the platform in the realities of oncology imaging, staging, and treatment response assessment.
Mayo Clinic AI leadership
At Mayo Clinic, Dr. Shreve founded the Hematology AI Group and helped move early AI work from theory into usable hematology and oncology research workflows.
Technical foundation
Software development, bioinformatics, computer vision, and imaging analytics support end-to-end pipeline design from DICOM ingestion through segmentation, radiomics, and export.
CORE EXPERTISE
What the platform actually does
This redesign keeps the site centered on Ingensia’s strongest differentiator: high-value PET/CT computer vision and the analysis pipeline that follows it.
Automated PET/CT lesion segmentation
Whole-body segmentation of FDG-avid disease with disease-burden outputs designed for practical use in DLBCL and related hematologic malignancies.
Radiomics at scale
Extraction of tumor shape, intensity, surface, texture, and burden features after segmentation, enabling standardized imaging biomarker generation per scan.
Exploratory machine-learning workflows
Integration of radiomics with clinical and laboratory variables for risk stratification, response modeling, survival analysis, and biologic correlation studies.
DICOM-aware engineering
Robust CT/PET series detection, reconstruction-aware selection, resampling, QC, and reporting so the pipeline is usable on real clinical imaging archives rather than hand-curated toy datasets.
BENCHMARK
Blinded comparison against the next-best open-source lymphoma PET/CT model
For public benchmarking, Ingensia was compared against the next-best open-source lymphoma PET/CT computer-vision baseline we could directly run in this disease space: the French Blanc-Durand/TMTV pipeline1, 2. The goal is simple enough for a clinician and rigorous enough for a technical reviewer: determine whether the software outlines disease more closely to expert reference masks on held-out DLBCL scans.
Better tumor masks make the measurements that follow more trustworthy.
For a non-technical physician, the central question is not the architecture name. It is whether the software actually outlines the disease correctly. In this blinded comparison, Ingensia tracked the expert reference masks much more closely than the next-best open-source lymphoma PET/CT model.
More complete disease outlining means tumor-burden measurements are less likely to miss clinically meaningful volume.
Segmentation quality matters upstream because radiomics, SUV metrics, and downstream modeling all depend on that mask.
higher mean Dice than the next-best open-source lymphoma PET/CT model
Mean Dice was 0.8208 for Ingensia versus 0.4906 for the next-best open-source comparator on the blinded 10-case DLBCL hold-out, with higher Dice in 9 of 10 cases and materially stronger recall.
The next-best open-source baseline
The public comparator used here is the French Blanc-Durand/TMTV lymphoma PET/CT model1, 2. It is a meaningful public benchmark because few open-source lymphoma-specific PET/CT segmentation models exist in this domain.
- Designed for lymphoma lesion segmentation and TMTV-oriented analysis.
- Distributed as a public inference wrapper around the French model.
- Expects user-prepared NIfTI pairs: CT as
patientID_0000and PET aspatientID_0001in SUV2.
What the full Ingensia workflow adds
Ingensia does not stop at a segmentation call. The observable stack handles DICOM normalization, CT/PET series nomination, PET-to-CT-grid harmonization, nnU-Net v2 low-resolution and full-resolution inference, ensembling, postprocessing, QC, radiomics extraction, and packaged reporting5, 6.
- DICOM-aware preprocessing and heuristic series selection are part of the product.
- Dual-branch nnU-Net v2 inference is followed by ensemble and postprocessing.
- Downstream outputs include SUV burden metrics, radiomics, QC artifacts, an HTML report, and an interactive viewer.
Why the benchmark is worth taking seriously
The reference masks come from the FDG-PET-CT-Lesions dataset, where FDG-avid lesions were manually segmented in 3D and reviewed in consensus when needed3, 4. That gives the comparison an open and auditable ground-truth backbone.
