Gruppe 4: The Radiology Gamuts Ontology

Introduction

The Radiology Gamuts Ontology (RGO) is a formal knowledge model of differential diagnoses in radiology^[1]. It includes:

• 16,918 entities
• 12,888 "causes" (conditions that cause findings)
• 4,663 "effects" (e.g., imaging findings)
• 1,782 hierarchical ("is-a") links
• 55,569 causal ("may-cause") links

Using The Radiology Gamuts Ontology

To use The Radiology Gamuts Ontology:

1. Start an internet browser (Firefox or Internet Explorer)
2. Navigate to the following URL: http://gamuts.net

On the left are a number of different sections, such as Head and Neck Radiology or Vascular Radiology. If you choose Chest Radiology, the following appears:

What you see are a list of gamuts under the section Chest Radiology. Choose a gamut, such as Chylothorax, and you will see the following:

• On the right, a number of images with Chylothorax present.
• You see synonyms for Chylothorax, in this case Lymphothorax.
• You see "is-a" relationship(s), in this case Pleural effusion.
• A number of entries under "May Cause"
• A number of entries under "May Be Caused By"
• Under "May Be Caused By" we have a number of Common and Uncommon diagnoses for Chylothorax.

The images can be clicked, and link to published academic work:

The image above links to the American Journal of Roentgenology, where a description of the image can be seen:

Here more text is stated regarding the findings: "Major leak in 61-year-old woman with chylothorax after partial esophagectomy for malignant melanoma of esophagus^[2]."

Clicking on a common diagnosis, such as Lung cancer, and you will see the entry for this disease, giving a list of synonyms and diseases that it may cause:
