Best PET-CT reading software in India
By SOMATIQ team ·
PET-CT reading has usually meant a dedicated workstation in one room, often from the scanner's vendor, with a nuclear medicine physician walking to it for every case. That works for one site and one reader. It works less well when reports are signed from home, when an oncologist wants to see the hot spot with you, or when a chain adds a second PET-CT in another city.
This guide lists PET-CT and nuclear medicine reading software, from each vendor's own public page read on 11 November 2026. We have not tested or ranked them. The pages vary a lot in what they state, so treat every gap as a question for a demo.
What matters in PET-CT software
- Fusion. PET colour over CT, with registration you can adjust, so a hot spot lands on the right node, bowel loop or bone.
- Quantification. SUV measurements (SUVmax, SUVmean, and the body-weight or lean-body-mass variant your physicians use) that you can reproduce at follow-up.
- MIP and 3D views. A rotating maximum intensity projection is how most readers get the overview of a whole-body study.
- Follow-up comparison. Baseline and follow-up side by side, registered, for response assessment.
- Where it runs. A dedicated workstation, a server with thin clients, or a browser. This decides whether a physician can report from home or show a case to an oncologist on a call.
- One archive. PET-CT should live in the same archive and worklist as CT, MRI and X-ray, not on an island.
PET-CT reading software options
| Option | PET-CT features named on its page | Where it runs, as stated |
|---|---|---|
| SOMATIQ | PET/CT fusion in the browser viewer, threshold-based 3D lesion segmentation, nuclear medicine in the same archive and worklist, priors side by side | Browser, zero-footprint |
| Siemens Healthineers syngo.via | "fuses hybrid studies and registers them across up to 8 time points"; segmentation and quantification | Client-server or workstation; "can be fully integrated into the RIS/PACS workstation of all major vendors" |
| GE HealthCare PET Advanced Visualization | "fuse and register two volumetric acquisitions"; "evaluate lesion metabolic activity over time" | Not stated on the page |
| Hermes Medical Solutions | Fusion with alpha blending; "SUV mouse mode for quick and easy SUVmax localization"; multi-timepoint registration | Not stated on the page |
| Sectra NM Fusion | "Support for SUVbw mean and max value"; "Fully triangulated PET/SPECT MIP view" | Server-based, used from Sectra PACS workstations |
| Fujifilm Synapse 3D | Lists a "Nuclear Medicine Viewer" and "Fusion Viewer" | Not stated on the page |
| Medsynaptic (Inobitec Pro) | "Switching between Mono PET, Mono CT, PET-CT"; "3D MIP for PT Series" | Third-party viewer offered by Medsynaptic |
GE HealthCare also owns MIM Software, which describes PET and SPECT quantification with "thick and thin clients". Each row reflects what the vendor's own page states; "not stated" does not mean "not available".
Where SOMATIQ fits
We build one of the options above. SOMATIQ puts PET/CT fusion in the same browser viewer that radiologists use for CT and MRI, with threshold-based 3D lesion segmentation that can be repeated at follow-up. PET-CT and nuclear medicine studies sit in the same archive and worklist as everything else, so baseline and follow-up open side by side, and a physician can share the viewer with an oncologist to go through a case together. Our pages do not list SUV variants, so ask us to show the measurements you use. See PET/CT and nuclear medicine.
Questions to ask in a PET-CT demo
- "Show me SUVmax on this lesion, and the same lesion at follow-up." With the SUV variant your physicians use.
- "Open a whole-body PET-CT from home, on a laptop." How long does it take, and what has to be installed?
- "Can I adjust the fusion registration?" Misregistration at the diaphragm is common.
- "Where do PET-CT studies live?" In the main archive and worklist, or in a separate system?
- "Does it work with our scanner's vendor?" Ask for a site using the same PET-CT model.

FAQ
What is the best PET-CT software in India?
It depends on whether your physicians read at one workstation or need to report from anywhere, and on which quantification they rely on. Shortlist from the table, then test each option with your own studies and SUV measurements.
Can PET-CT be read in a web browser?
Yes. Browser viewers can now show PET-CT fusion and 3D views without an installed workstation. Ask to open a whole-body study on an ordinary laptop to see how it performs.
Should PET-CT studies be in the same PACS as CT and MRI?
Usually yes. One archive and worklist means priors from any modality open together, and nuclear medicine is not left on a separate island.
