Presentation transcript:

Esophagus and UGI

Patient Preparation Ask if patient has any metal objects in clothing ( zippers, buttons, snaps, etc.) Any jewelry that might obscure the certain areas of interest. ( navel rings) Present patient with a gown to change into.

Esophagus One view RAO 14 x 17 Lengthwise Average technique 110 @3

Positioning Patient prone on the table Rotate 35-40 with the right anterior portion against table. Place right arm down beside patient Left arm flexed at elbow by patient’s head to hold cup Flex left knee for support Shield patient at waist.

CR is perpendicular to T5-T6 About 3 inches below jugular notch SID 40 Collimate about 6 inches wide. Place marker in light field Suspend breathing

Film critique Esophagus should fall between spine and heart. Esophagus should be filled with barium Adequate rotation

UGI 3 views AP, 14 x 17 LPO, 11 x 14 Right Lateral 11 x 14 Page 480 125 @ 4-7

AP Positioning Patient is supine on the table. Align stomach to midline of table. Ensure body is not rotated. Arms at side Place shield over waist

Mid-way between lower rib margin and Xiphoid tip SID 40 CR perpendicular to L1 Mid-way between lower rib margin and Xiphoid tip SID 40 Collimate to cassette and place marker in light field Expiration

Different centering positions for all positions Sthenic patient is at L1 Hypersthenic is 1 inch above L1 Asthenic is 2 inches below L1 and nearer to mid-line

Film Critique Entire stomach and duodenum Diaphragm and lower lung fields Fundus is filled with barium

Positioning of patient for LPO Patient supine on table Rotate 30-60 degrees from supine depends on size of patient. Flee knee for support Extend left arm from body and raise right arm across chest to hold to side of table Place bottom of cassette or Light at the top of the crest Shield patient at waist.

Rotation for LPO UGI Sthenic 45 degrees Hypersthenic 60 degrees Asthenic 30 degrees

CR midway between xiphoid tip and lower rib margin mid-way between the midline and left lateral side. SID 40 Collimate to cassette and place marker in light field Expiration

Seen on Film Stomach and duodenum The duodenal bulb Barium filled fundus

Positioning for Right lateral Roll patient up on right side Shoulders and hips in true lateral positioning Flex knees and position arms up out of way Midline is 1 to 1 ½ posterior to midline of table Place shield over waist

bottom of light at top of crest SID 40 Collimate to cassette CR L1 and 1-1 ½ inches anteriorly bottom of light at top of crest SID 40 Collimate to cassette Expiration

Film Critique Entire stomach Retrogastric space No rotation
