Computed axial tomography (CAT scan) is used in the diagnosis and evaluation of several gynecological conditions, including:

• Cancers. CAT scans are often used in evaluating gynecological cancers, such as those of the ovaries and the endometrium. Generally, they are used more often to stage these cancers than to diagnose them. Staging is the process of determining how far cancer has spread in the body. Analysis of the tissue under a microscope is necessary in order to determine a definitive diagnosis.
  
  

  
• Other pelvic and intra-abdominal conditions. CAT scans can be used to diagnose:
  
• • Abscesses. A localized collection of pus.
    
    
  • Appendicitis. Inflammation of the vermiform appendix.
    
    
  • Cystic teratoma. Tumors that are composed of more than a single cell type derived from more than one germ layer. Cystic teratomas tend to appear in the ovaries.
    
    
  • Ovarian vein thrombophlebitis. Uncommon but potentially serious disorder associated with a variety of pelvic conditions, especially recent childbirth.
