Making the diagnosis of FAP before the development of colon cancer is important insofar as not only the individual but also affected family member's survival is at stake.
**Colonoscopic spectroscopy is a near-infrared autofluorescence (NIR AF) experimental method that is performed as an adjunct to diagnosis of [[Colon (anatomy)|colon]] lesions. 
===Colonoscopy===
**Colonoscopic spectroscopy has 80% sensitivity and 90% specificity. 
[[Colonoscopy]] is considered the diagnostic test of choice as it can provide not only a quantification of [[polyps]] throughout the [[colon]] but also a histologic diagnosis.Once the diagnosis of FAP is made, close [[colonoscopy|colonoscopic]] surveillance with [[polypectomy]] is required. [[Prophylaxis|Prophylactic]] [[colectomy]] is indicated if more than a hundred polyps are present, there are severely dysplastic polyps, or multiple polyps larger than 1 cm are present. When partial [[colectomy]] is performed, colonoscopic surveillance of the remaining colon is necessary as the individual still carries significant risk of developing colon cancer.

Overview

Colonoscopic spectroscopy and narrow-band imaging (NBI) may be helpful in the diagnosis of familial adenomatous polyposis.

Other Imaging Findings

  • Colonoscopic spectroscopy may be helpful in the diagnosis of familial adenomatous polyposis.[1]
    • Colonoscopic spectroscopy is a near-infrared autofluorescence (NIR AF) experimental method that is performed as an adjunct to diagnosis of colon lesions. 
    • Colonoscopic spectroscopy has 80% sensitivity and 90% specificity. 
  • Narrow-band imaging (NBI) may be helpful in the diagnosis of familial adenomatous polyposis.[2]
    • NBI is an endoscopic optical image enhancement technology based on light penetration.
    • NBI is one of the evaluated colonoscopy modality for diagnosis of adenoma.
