Study Notes
Fluoroscopic Procedures
Barium Swallow
- A barium swallow is a radiological study that employs a contrast agent to determine pathologies of the esophagus.
- Also referred to as esophagram in the USA.
- Uses barium sulphate, Gastrografin, or Ominipaque (Iohexol).
- Indications:
- Odynophagia (painful swallowing)
- Dysphagia (difficulty with swallowing)
- Narrowing or irritation of the esophagus
- Hiatal hernia
- Gastroesophageal reflux disease (GERD) or GORD
- Anemia
- Blood-stained vomitus
- Assessment of tracheo-esophageal fistula
- Unexplained weight loss
- Contraindications:
- Complete obstruction
- Perforation (especially after recent surgery)
- Recent gastric or esophageal surgery
- Complications:
- Leakage of barium from an unsuspected perforation
- Allergic reaction or anaphylaxis
- Constipation
- Aspiration of barium
- Major complications:
- Barium peritonitis (leakage of barium from an unsuspected perforation)
Barium Meal
- A diagnostic test used to detect abnormalities of the stomach and duodenum.
- Methods:
- Double contrast: demonstrates mucosal pattern and abnormality
- Single contrast: used for children or very ill adults
- Indications:
- Unexplained weight loss
- Abdominal mass
- Gastrointestinal hemorrhage
- Unexplained iron-deficiency anemia
- Partial duodenal obstruction
- Assessment of site of perforation
- Gastrointestinal reflux
- Contraindications:
- Large bowel obstruction
- Immediate or impending gastric/abdominal surgery
- Anatomy:
- Stomach
- Duodenum
- Preparation:
- Check patient identification
- Check for pregnancy
- Patient must be fasted for 6-8 hours
- Medical history should be taken
- Appropriate laboratory results and other examinations must be reviewed prior to the examination
- The procedure should be explained to the patient prior to the examination
- The patient must sign a consent form for the examination
Barium Follow Through
- Demonstrates the small bowel from the duodenum to the ileocecal region.
- Indications:
- Partial obstruction
- Abdominal masses
- Failed small bowel enema
- Ulcer
- Post-operative ileus (use of gastrografin)
- Crohn’s disease
- Suspected small bowel neoplasm
- Suspected small bowel obstruction that has been managed conservatively
- Technique:
- Aim is to deliver a single column of barium into the small bowel
- If performed in conjunction with a barium meal, continues after the meal procedure
- Prone abdomen taken every 20 minutes during the first hour of patient drinking solution
- Subsequent radiographs taken at 30 minutes until the colon is reached
Barium Enema
- Indications:
- Ulcerative colitis
- Crohn’s disease
- Infection or inflammation
- Obstructions and polyps
- Cancer
- Unusual bloating or lower abdominal pain
- Changes in bowel movements
- Contraindications:
- Suspected bowel perforation
- Severe ulcerative colitis
- Pregnancy
- Toxic megacolon
- Acute abdominal pain
- Preparation:
- Patient must be on a light diet prior to the exam
- Castor oil or Mist Sennco in the evening after the last meal
- Anatomy:
- Large intestine
- Technique:
- Single Contrast Study
- Double Contrast Study
Intravenous Urography (IVU)
- A radiological procedure used to visualize abnormalities of the urinary system.
- Indications:
- Repeated infections
- Renal colic
- Flank pain
- Trauma
- Retention and decreased urinary output
- Kidney stones
- Renal cell carcinoma
- Polycystic kidneys
- Contraindications:
- General contraindications to contrast agent
- Hepato renal syndrome
- Pregnancy
- Blood urea raised above a certain defined or normal level
- Anuria, or absence of urine excretion
- Diabetes, especially diabetes mellitus
- Severe hepatic or renal disease
- Patients taking certain medications
- Patient preparation:
- Abdominal preparation
- Projections:
- Control
- Immediate
- 5 minutes
- 10 minutes/15 minutes
- 20 minutes
- Post-void
Hysterosalpingography (HSG)
- A radiographic examination of the female reproductive system.
- Indications:
- Female infertility
- Recurrent spontaneous abortions
- Congenital uterine anomalies
- Post-operative evaluation of tubal ligation
- Investigation of uterine pathologies
- Contraindications:
- Pregnancy
- Acute pelvic inflammatory or infectious conditions
- Active vaginal bleeding
- Recent cervical dilation and curettage
- Recent tubal or uterine surgery
- Sensitivity to contrast
- Contrast media:
- Water-soluble non-ionic iodinated contrast media (Omipaque, Iohexol, Iopamiro, Ultravist)
- Oil-based contrast (Lipidol)
- Equipment and accessories:
- Speculum
- Cannula
- Tenaculum
- Uterine sound
- Patient preparation:
- The procedure is done during the proliferative phase of the menstrual cycle
- The patient must be advised to avoid sexual intercourse from the onset of her period to the day of the exam
- β-HCG test (Beta human chorionic gonadotropin tests) should be carried out.### Patient Preparation for HSG
- 40mg of Buscopan is given to the patient an hour prior to the exam to reduce pain from cramps
- Mild analgesics and prophylactic antibiotics may be given to prevent pain and potential infections
- The patient may be asked to empty their bladder to prevent displacement of the uterus and uterine tubes
Procedure for HSG
- Informed consent is obtained before the procedure starts
- The patient is placed in lithotomy position with legs bent at the knee or supported with stirrups
- The patient is draped with sterile towels and the perineum is cleaned with antiseptic solution
- A vaginal speculum is inserted and the cervix is localized and cleaned with antiseptic solution
- The cervix is cannulated, and dilation with a balloon catheter helps to occlude the cervix
- A tenaculum may be necessary to aid in insertion and fixation of the cannula or catheter
- The patient is placed in a slight Trendelenburg position to facilitate the flow of contrast media into the uterine cavity
Injecting Contrast Media
- A syringe filled with contrast media is attached to the cannula or balloon catheter
- Using fluoroscopy, the radiologist/radiographer slowly injects contrast media into the uterine cavity
- If the uterine tubes are patent, contrast media flows from the distal ends of the tubes into the peritoneal cavity
- About 10-20ml of contrast is used to fill the uterine cavity
Film Series
- An initial collimated scout image is taken with the patient in lithotomy position
- A series of collimated images may be obtained during injection of contrast media
- 4 spot films may be taken, including:
- Early filling phase
- Fully distended uterus
- Tubal filling phase
- Peritoneal spillage
Complications of HSG
- Pain from uterus dilation and peritoneal spillage
- Infection
- Bleeding
- Vascular intravasation
- Uterine perforation
- Contrast reactions
After Care for HSG
- Antibiotics may be given to fight or prevent infection
- Pain medicine may be needed to alleviate pain
- Vaginal care includes using vaginal pads for 1-2 days, washing with soap and water, and changing pads as needed
Cystography and Urethrography
- Cystography and urethrography involve imaging the bladder and/or urethra before, during, and after administration of contrast via urethral or cystostomy catheter
- The goal is to detect anatomic and/or functional abnormalities of the lower urinary tract
Indications for Cystography and Urethrography
- Cystography:
- Recurrent urinary tract infections
- Vesicoureteral reflux
- Bladder contour
- Bladder diverticula
- Suspected rupture
- Fistulae
- Integrity of postoperative anastomoses or suture lines
- Bladder outlet obstruction
- Incontinence
- Hematuria
- Neoplasia
- Urethrography:
- Urethral diverticula
- Urethral strictures
- Bladder outlet or urethral obstruction
- Trauma
- Recurrent urinary tract infection
