AI Visual Recognition Example OpenAI o4 model

Hello all, first I would like to say I apologize for my absence for the last few months. I was dealing with a personal , family issue that monopolized my time. The good news is, the issue is resolved, and I intent on getting back to writing articles for the blog.

This quick article, is just an example of how far the AI/LLM's are progressing. In this example, I setup the o4 model with visual recognition capabilities. I simply went to a Radiology website for learning, and took example pictures and simply uploaded it to the Model without any prompts. It analyzed the image, and returned stunning results. It described the findings to match what the learning website stated about the image.

The Images Below I sent to the model. First one is a normal chest X-ray, the second one is showing Cardiomegaly.

Here is what the Model returned summarizing findings of both images.

Here’s a quick side-by-side comparison of the two PA chest X-rays:

Lung fields

Study 1 (08:00:52): Both lungs are clear. No focal consolidation, masses, pneumothorax or pleural effusion.

Study 2 (08:02:12): There is a subtle increase in bronchovascular markings—most pronounced at the right lung base—and a trace of subsegmental atelectasis there. No definite lobar consolidation or effusion.

Cardiac silhouette & mediastinum

Study 1: Heart size and mediastinal contours are within normal limits.

Study 2: The cardiac silhouette is at the upper limit of normal (cardiothoracic ratio borderline). Mediastinum remains midline.

Diaphragm & pleural recesses

Study 1: Both hemidiaphragms are well-defined, costophrenic angles sharp.

Study 2: Right hemidiaphragm is slightly elevated compared with the first, and there is minimal blunting of the right costophrenic sulcus consistent with that atelectasis.

Bones & soft tissues

No new rib fractures or bony lesions in either study. Soft-tissue windows look similar.

Impression:
– The first image is essentially normal.
– The second shows mild interval increase in right basilar atelectasis/bronchovascular markings and a borderline increase in heart size. These findings are subtle and could reflect early atelectasis or mild pulmonary congestion; there is no frank pneumonia, pleural fluid, or pneumothorax.

Would you like:
• An annotated overlay highlighting exactly where these changes are?
• A draft report formatted for your RIS/PACS?
• Further comparison measurements (e.g., exact cardiothoracic ratio)?

Closing Thoughts

My girlfriend who is a Doctor, confirmed the radiologists are now using AI to read images and check their work. The rate at which AI is progressing, has surprised me on many levels. I use it regularly to create or adjust code that I could not write compose myself. Not to mention troubleshoot code for issues, analyzing, making recommendations and changing the code in seconds.

Truly an exciting time we live in. Don't fear AI, embrace it. Those who don't, will be left behind.

Best....
