A bronchoscopy test involves using a flexible scope called a bronchoscope to examine the airways.

But all those with positive test results had to undergo a costly colonoscopy, a procedure in which a flexible scope is used to examine the entire five feet of the lower bowel.

Introducing a flexible fiberoptic scope into the hypopharynx to obtain a view, the examiner may witness the collapse and identify weakened sections of the airway.

It is used: When there is bleeding in the airway that could block the flexible scope's view.

Doctors are devising new deep-body injection techniques: syringes attached to flexible scopes or to probes that detect electrical impulses in muscles.

In more severe cases, a procedure wherein a flexible scope is passed through the mouth into the lungs (bronchoscopy) can be used to collect fluid for culture.

In a colonoscopy, a doctor pushes a flexible scope, called an endoscope, to the top of a patient's colon, near the appendix, and slowly withdraws it, looking for adenomas.

The flexible scope initially employed fiberoptic bundles requiring an external light source for illumination.

To confirm how much insulation is inside the wall, the auditor will use a borescope, a flexible optical scope that can be inserted into the wall cavity through a small hole.
