    Barium follow-through

    Used to evaluate the small intestine

    Contrast medium appears white on x-

    rays,showing internal lining of the bowel

    X-ray images taken as the contrast moves

    through the intestine, commonly at 0 minutes,

    20 minutes, 40 minutes and 90 minutes

    Test completed when barium is visualized in

    the terminal ileum and Caecum

    Clinical Application

    Long segment narrowing of the jejunal loops with loss of mucosal pattern

    and bowel wall thickening.Diagnosis:Crohns disease

    Overhead image from a small bowel follow through in a

    patient with history of Crohn's disease demonstrates

    evidence of terminal ileal wall thickening, causing

    narrowing of the lumen.

    Frontal spot image from SBFT showssmooth elongated mass (black arrows) in

    distal ileum with telescoping of small bowel

    (intussusceptum, white arrow) into

    adjacent lumen (intussuscipiens), producing

    coil spring appearance (arrowheads). This

    patient had inverted Meckel diverticulumactin as lead oint for intussusce tion.

    49-year-old woman with Crohn's disease involving small bowel. Five years

    before these imaging studies were obtained, patient had undergone

    segmental resection of ileum because of protein-losing enteropathy. Spot

    compression image of small-bowel follow-through study obtained 1 day

    afterA shows linear ulcer (arrows) in mesenteric border and

    pseudosacculation (arrowheads) along antimesenteric border.

    Frontal spot image from SBFT shows primary adenocarcinoma

    of small bowel as annular lesion in jejunum, with

    circumferential narrowing, shelflike margins (black arrows),

    and small central ulcer (white arrow).

    Contraindications

    - known or suspected obstruction of the colon

    - suspected tracheoesophageal fistula,

    - known obstructing lesions of the small intestine,

    - pyloric stenosis

    - known hypersensitivity to barium sulfate formulations.- Imminent surgery and or suspected perforation; require water soluble

    contrast media.

    Adverse effects

    aspiration pneumonitis

    barium sulfate impaction

    granuloma formation

    intravasation, embolization and peritonitis following intestinal perforation

    vasovagal and syncopal episodes

    allergic reactions in atopic patients

    Small bowel enema(Enteroclysis)

    Alternative for small bowel examination

    A thin tube/catheter is passed down the

    oesophagus, through the stomach, and into

    the first part of the small intestine.

    Barium liquid is then poured down the tube

    Demonstrates strictures or adhesions whenthere is suspicion of intermittent obstruction

    Frontal spot image from enteroclysis shows normal

    folds in distal jejunum as thin (12-mm-thick)

    delicate structures perpendicular to longitudinal axis

    of bowel. There are normally four to seven folds per

    inch of jejunum.

    Frontal spot image from enteroclysis shows multiple smooth-

    surfaced hemispheric submucosal masses (white arrows) in small

    bowel; other lesions have bull's-eye appearance (black arrows)

    due to central ulceration. This patient had malignant melanoma

    with hematogenous metastases to small bowel

    Left posterior oblique spot image from enteroclysis shows

    partially obstructing adhesive band as vertically oriented,

    extrinsic, bandlike impression (arrows) traversing lumen of

    jejunum, with proximal dilatation.

    Barium Enema

    To examine and diagnose problems with thecolon(large intestine)

    Patient lies on the X-ray table and a preliminary X-ray istaken

    A well lubricated enema tube is inserted intothe rectum

    Barium sulfate and air/Co2 is then allowed to flow intothe colon

    A small balloon at the tip of the enema tube may beinflated to help keep the barium sulfate inside

    flow of the barium sulfate is monitored by the healthcare provider on an X-ray fluoroscope screen

    Frontal spot image from double-contrast barium

    enema examination (with reflux into terminal

    ileum) shows carcinoid tumor as smooth, sessile,

    1.5-cm-diameter polyp (black arrows) in terminal

    ileum. Also note multiple ileal diverticula (whitearrows).

    18-year-old woman with Crohn's

    disease involving colon. Image

    from double-contrast bariumenema reveals longitudinal and

    perpendicular ulcerations

    (arrows) in right colon.

    Peripheral T-cell lymphoma of the colon with diffuse

    involvement in a 42-year-old woman.Double-contrast barium

    enema image shows multiple shallow (arrows) and aphthous(arrowheads) ulcerations in the entire colon.

    Small ulcerations with a

    diffuse distribution

    (arrows) and geographic

    ulceration (arrowhead)
