With which of the following is zonography associated?

1. Thick tomographic cuts | 2. Less blurring than with pluridirectional tomography because a narrow exposure angle is used

To better demonstrate contrast-filled distal ureters during IV urography, it is helpful to

Which of the following is the correct sequence of events when performing a double-contrast upper GI series?

Patient is given gas-producing substance, then given a small amount of high-density barium, then placed recumbent.

Cholecystokinin

Ingestion of barium sulfate is contraindicated in which of the following situations?

1. Suspected perforation of a hollow viscus 2. Suspected large-bowel obstruction 3. Presurgical patients

The advantages of digital subtraction angiography over film angiography include

1. greater contrast medium sensitivity. | 2. immediately available images.

Which of the following examinations require(s) ureteral catheterization?

Retrograde pyelogram

is a radiologic procedure that functions to dilate a stenotic

Percutaneous angioplasty

When the erect position is requested as part of an IVP, it is used to demonstrate

Kidney Mobility

In myelography, the contrast medium is generally injected into the

subarachnoid space between the third and fourth lumbar vertebrae.

Knee arthrography may be performed to demonstrate a

The AP Trendelenburg position is often used during an upper GI examination to demonstrate

Hiatal Hernia

Which of the following equipment is necessary for ERCP?

Which projection(s) of the abdomen would be used to demonstrate pneumoperitoneum?

Left lateral decubitus | Upright

Which of the following interventional procedures can be used to increase the diameter of a stenosed vessel?

1. percutaneous transluminal angioplasty (PTA) | 2. stent placement

Radiolucent or negative contrast media include

swallowed air, CO2, gas crystals and normally present gas bubble in the stomach

Most common positive or radiopaque contrast medium

Barium Sulfate

Contraindication of Barium Sulfate

Perforated viscus Pre-operative *water-soluble, iodinated contrast is used but not to be used whrn patient is sensitive to iodine.

Will be demonstrated better with a double contrast technique

potential polyps, diverticulae and ulcers

Study the form and function of the swallowing aspects of the pharynx and esophagus

Esophagram

Dilation of the veins of distal esophagus. This condition is often seen with acute liver disease such as cirrhosis. In advance cases the vein may begin to bleed.

Esophageal varices

The use of _____ barium allows better visualization of mucosal patters and any lesion within the esophagus.

Thick

The patient may be asked to perform one of the following procedures to detect esophageal reflux

* Breathing exercises * The Water Test * Toe-Touch Maneuver

This maneuver forces air against the closed glottis. Patient is asked to take a deep breath and while holding the breath in, to bear down as though trying to move the bowels

Valsalva Maneuver

Is performed by having the patient exhale and then try to inhale against a closed glottis

Mueller Maneuver

Is done with the patient supine and turned up slightly on his left side. This LPO position will fill the fundus with barium. Px is asked to swallow a mouthful of water through a straw. Radiologist will closely observe the esophagogastric junction under fluoroscopy

Water Test

Is performed to study possible regurgitation into the esphagus from the stomach. The cardiac orifice is observe as the patient bends over and touches his or her toes. Esophageal Reflux and Hiatal Hernias are sometimes demostrated in this

Toe-Touch Maneuver

Three positions or projections are considered routine for an esophagram or barium swallow

RAO Left lateral AP

Radiographic examination of the distal esophagus, stomach and duodenum is termed an

Upper GI Series

Is a mass of undigested material that gets trapped in the stomach. This mass is usually made up of hair, certain vegetable fibers or wood products.

Bezoar

Are a weakening and outpouching of a portion of the mucosal wall.

Diverticulae

Diffuse fatty inflitration of the hepatic parenchyma may be referred to as:

Steatosis

An enterovesical fistula is an abnormal communication btw the bowel and the

Bladder

Prior to a CT colongraphy, the patient may undrgo a process of bowel cleansing termed:

Catharsis

The condition of intermittent cramping pain in the legs due to poor circulation is called

Claudication

Which of the following terms is used to describe a fibroid tumor of the uterus?

Leiomyoma

Which of the following may be included as part of a routin preparation for a general contrast-enhanced CT examination of the abdomen and pelvis?

Instructing the pt to take nothing by mouth for 4 hrs prior to exam 1200 mL of oral contrast agent administered 90 min. prior to exam

Which of the following contrast media may be utilized during the CT evaluation of the gastrointestinal tract?

Diatrizoate meglumine (Gastrografin) Effervescent agents Iopamidol (Isovue)

The function of the "cardia" is to:

Push food into the stomach via the oesophagus

To which side does the common bile duct reside, relative to the stomach?

Bottom left

Radiographs with the patient in the decubitus position are produced following an air-contrast barium enema examination. The radiographer fails to properly label the radiograph. To identify the right lateral decubitus image, the radiographer should see:
