Fluoroscopy

Fluoroscopy is used to study moving body structures. An x ray beam is continuously passed into the body part to be examined it is transmitted to a TV-like monitor so that the body part in motion is studied in detail. As an imaging technique, fluoroscopy is commonly employed by physicians to obtain real-time images of the internal structures of a patient during minimally invasive and microscopic surgical procedures, as well as many types of diagnostic tests like discography.

Fluoroscope: In its simplest form, fluoroscopy consists of an x ray source and a fluorescent screen between which a patient is placed. Modern fluoroscopes couple the screen to an X ray image intensifier and a video camera allowing the images to be played and recorded on a monitor. Traditional fluoroscopes consisted of an x ray source and fluorescent screen between which the patient was placed. Modern fluoroscopes have shown several improvements in screen phosphors, image intensifiers and even flat panel detectors. These allow for increase quality while minimizing the radiation dosage to the patient. Modern fluoroscopes also use the CSI screens and produce noise-limited images. This ensures minimal radiation dosage results while still obtaining images of acceptable quality.

Fluoroscopy can be adopted on an inpatient or outpatient basis. Depending upon the specific type of procedure or examination, it is determined whether any preparation prior to the procedure is required. All fluoroscopic procedures pose potential health risk to the patient. Fluoroscopy uses more radiation than standard x rays. Radiation doses depend upon the size of the patient as well as the length of the procedure. Fluoroscopy is widely used in orthopedic surgery to guide fracture reduction and the placement of metal work. Fluoroscopy is used in many diagnostic and therapeutic radiological procedures to observe the action of instruments being used either to diagnose or to treat the patient. Fluoroscopy is also used to help find a foreign object in the body, position a needle for a medical procedure or re align a broken bone. Different types of fluoroscopy procedures:

  • Esophogram: x ray study of the throat.
  • Upper GI series: is a study of the esophagus, stomach and duodenum.
  • Small bowel series: is a study of the stomach and entire small intestine.
  • Barium enema: is a study of colon.
  • Hysterosalpingogram: is a study of the uterus and fallopian tubes.
  • Intravenous Pyelography: is a study of the kidneys, ureters, and the urinary bladder.
  • Voiding cystourethrogram: is the study of the bladder and urethra.
  • Arthrogram: is a study of the shoulder and knee joint showing ligament and tears.
