Study Notes
Types of Endoscopes
- Esophagoscopy: Used to visualize the esophagus
- Gastroscopy: Used to visualize the stomach
- Colonoscopy: Used to visualize the colon
- Sigmoidoscopy: Used to visualize the sigmoid colon
X-Ray and Other Imaging Techniques
- MRI: Magnetic Resonance Imaging uses magnetic fields and radio waves to create detailed images of organs and tissues
- CAT Scan: Computed Axial Tomography uses X-rays and a computer to create cross-sectional images of the body
- Barium Swallow: A contrast medium (barium) is swallowed to visualize the esophagus, stomach, and duodenum
- Barium Enema: A contrast medium (barium) is inserted into the rectum to visualize the colon and rectum
- Upper GI Series: Uses X-rays and a contrast medium (barium) to examine the upper digestive tract
- Cholangiography: A procedure that uses a contrast medium to visualize the bile ducts
- Cholecystography: A procedure that uses a contrast medium to visualize the gallbladder
- Liver Scan: Uses radioactive isotopes to create images of the liver
- Ultrasound: Uses sound waves to create images of internal organs and structures
Eating Disorders
- Anorexia: Characterized by an intense fear of gaining weight and a distorted body image. It often leads to severe food restriction and excessive exercise.
- Bulimia: Characterized by episodes of binge eating followed by purging behaviors, such as vomiting, using laxatives, or excessive exercise.
- Obesity: Defined as having excessive body fat that can lead to health problems. Typically results from consuming more calories than are burned.
Diagnostic, Procedural, and Laboratory Terms
- Endoscopies are procedures using a long, flexible tube with a camera to visualize the inside of the body.
- Esophagoscopy examines the esophagus.
- Gastroscopy examines the stomach.
- Colonoscopy examines the colon (large intestine).
- Sigmoidoscopy examines the sigmoid colon (the last part of the colon).
X-Ray and Other Imaging Techniques
- MRI (Magnetic Resonance Imaging) uses magnetic fields and radio waves to create detailed images of organs and tissues.
- CAT scan (Computed Axial Tomography) uses X-rays to create cross-sectional images of the body.
- Barium swallow uses a contrast medium, barium, to make the esophagus, stomach, and small intestine visible on X-rays.
- Barium enema uses barium to visualize the colon on X-rays.
- Upper GI series uses X-rays to examine the esophagus, stomach, and small intestine.
- Cholangiography uses contrast medium to visualize the bile ducts.
- Cholecystography uses contrast medium to visualize the gallbladder.
- Liver scan uses radioactive tracer to visualize the liver.
- Ultrasound uses sound waves to create images of organs and tissues.
Pathological Terms
- Anorexia is a serious eating disorder characterized by a morbid fear of gaining weight and a refusal to maintain a healthy weight.
- Bulimia is a serious eating disorder characterized by episodes of binge eating followed by purging behaviors like vomiting, excessive exercise, or laxative use.
- Obesity is characterized by excessive body weight, often due to overeating and lack of physical activity.
