Lecture 8 exam study - SBFT
| Question | Answer |
|---|---|
| A radiographic and fluoroscopic procedure that demonstrates the form and function of the Small Intestine | Small Bowel Follow Through (SBFT) |
| Exam that investigates how fast it takes the contrast medium to travel through the entire small intestine | A motility or timed exam - a functional study |
| An inflammation of the Small Intestine - may be caused by bacterial or viral infections | Enteritis |
| A form of inflammatory bowel disease of unknown origin - often referred to as Crohn's Disease | Regional Enteritis |
| Radiographic signs of Crohn's Disease or Regional Enteritis | Cobblestone appearance of the intestine from scar tissue or string sign where segments of the intestine become narrowed |
| A common infection of the lumen of the small intestine that is caused by a flagellate protozoan - often spread by contaminated food and water - often affects the Duodenum and Jejunum | Giardiasis |
| malignant tumors found in the small intestine - radiographically produce short "napkin ring" defects within the lumen of the bowel | Adenocarcinomas |
| An obstruction of the Small Intestine - radiographically appearance of dilated loops of small bowel that look like stacks of coins on their side | Ileus |
| Two types of Bowel Obstructions (Ileus): | Adynamic and Mechanical |
| Examples of Mechanical Bowel Obstructions: | Volvulus (twisting of intestine), adhesions (scar tissue), Intussusception (telescoping of bowel) |
| Examples of Adynamic Bowel Obstructions: | loss of voluntary movement or lack of peristalsis caused by medications, surgery, anesthesia, or disease process |
| A general term used to describe a variety of malabsorption syndromes in which the gastrointestinal tract is unable to process and absorb certain nutrients | Sprue |
| An autoimmune response to eating gluten, a protein found in wheat, barley, and rye | Celiac Disease |
| Procedure performed to investigate the Stomach along with the Small Intestine (after UGI Overheads, patient drinks an additional cup of barium - images are taken of specific time intervals until contrast passes Large Intestine) | UGI with SBFT |
| Procedure of the Small Intestine (patient drinks 2 c. barium, Overhead imaging at specific time intervals, 15-30 m/first hour, after every 30 m until barium reaches Large Intestine) | SBFT |
| A radiographic and fluoroscopic procedure of the Small Intestine though an NG or feeding tube | Enteroclysis |
| A radiographic and fluoroscopic procedure of the Small Intestine through a specialized NG Tube called Bilboa or Sellink tube (placed in Jejunum through nose, WSICM or thin barium admin. by syringe attached to NG tube, contrast injected) THERAPEUTIC | Intubation SBFT |
| What procedure can be therapeutic if the patient has a known Small Bowel Obstruction | An Intubation SBFT |
| Once tube placement has occurred with an Intubation SBFT procedure, what is done with the tube? | it is connected to a suction machine to remove gas and fluid to relieve distention of the bowel caused by SBO |
| With thin barium administered during a SBFT, if the patient exhibits Hypomotility of the Small Intestine, what may be provided to promote the transition time of the Barium? | Ice water |
| What travels faster through the GI tract than barium sulfate? | Water-soluble Iodinated Contrast Media |
| What may be added to Barium to increase peristalsis and transit time of contrast media through the Small Intestine? | Water-soluble Iodinated Contrast Media |
| When is Water-soluble contrast media used in a SBFT exam? | When Barium Sulfate is contraindicated |
| What projection is commonly performed if a Small Bowel Follow Through examination is ordered without performing the UGI first? | An AP SCOUT Projection |
| When is the Fluoroscopic procedure performed in a SBFT and why? | At the end of the procedure to demonstrate the Ileocecal Valve and to document that the entire length of the Small Intestine has been investigated |
| What should you tell the patient to prepare them for the examination? | Make sure that the patient understands this could be a long procedure and that it depends on motility of their digestive system |
| Imaging sequence for a SBFT: | 15 minute (if performed with UGI) 30 minute (If SBFT only) 45 minute 60 minute 90 minute 2 hour |
| SBFT procedure images: 1 2 | 1. AP SCOUT Projection 2. AP/PA Overheads after ingestion of Barium Sulfate |
| AP SCOUT Projection - SBFT: CR: kV: Symphysis Pubis: | CR: Perpendicular 2-3 inches above Iliac Crest (to include upper abdomen kV: 70-80 kV is used because there is no contrast in abdomen Symphysis Pubis: does not have to be included - this is an upper abdomen image |
| AP/PA Overheads after ingestion of Barium Sulfate - SBFT - depends upon the? | Preference of Radiologist and Patient condition |
| The PA Projection (prone recumbent) Overhead after ingestion of Barium Sulfate, is preferred if tolerated by patient because: 1. 2. | 1. It places the Small Intestine closer to the Image Receptor 2. It utilizes natural compression to separate the loops of the bowel, making each segment more visible |
| Each image for a SBFT must be marked or annotated with what? | The time taken |
| 1st Projection after ingestion of barium Sulfate: CR: kV: | CR: Perpendicular 2-3 inches above Iliac Crest kV: 100-125 |
| Additional Projections after ingestion of barium sulfate: CR: | CR: level of Iliac Crest Symphysis Pubis is included |
| One or more of the following structures will be demonstrated on the last overhead image: | 1. The terminal Ileum or Ileocecal valve on last timed image 2. Cecum or Ascending Colon visualized - visible differences in diameter and location of barium 3. Large Intestine located around the periphery of the abdomen - haustral markings 4. Appendix |
| kV for a SBFT? | high kV 90-125 |
| A very thin barium, contains a 0.1% barium sulfate suspension | Volumen |
| When a patient is intubated, where is imaging done for the fluoroscopic procedure? | CT department for imaging |
| Procedure of the Small Intestine that requires luminal distension, by Oral or Jejunal administration of contrast medium | MR Enteroclysis |
