catheterization laboratory or cath lab is an examination room in a hospital or clinic with diagnostic imaging equipment used to visualize the arteries of the heart and the chambers of the heart and treat any stenosis or abnormality found.

In an Angiography Suite (Also called Special Procedures or Angio Lab) the focus expands to other parts of the circulatory system. The legs, arms, neck and head are imaged to determine if there are blocked or compromised blood vessels. A corrective procedure, called an angioplasty, can be done to repair a blocked or narrowed vessel

The Cath Lab is focused specifically on the heart, so the patient will be situated on the table with the imaging device focused on the center of the chest. In an Angio suite, the study may be on an arm, leg, or other area of the body, so the imaging table may be extended to allow the part of the body to be underneath the imaging device.
