NVIDIA Releases NV-Reason-CT, a 3D Vision-Language Model for Chest and Abdominal CT

NVIDIA's NV-Reason-CT is a 3D vision-language model for CT image analysis that combines a native 3D vision encoder with a language model.

It is designed for radiology report generation, question answering, and multi-step reasoning across chest and abdominal CT volumes.

The model converts a 384×384×384-mm input into 13,824 visual tokens without spatial downsampling and is available on Hugging Face under the OpenMDW-1.1 License.
