Radiographic Procedures Flashcards
Cricoid cartilage of larynx is in what level
Level of C6
Esophagus terminates at its connection to the stomach at the level of
T11
Act of swallowing
Deglutition
Is an inflammation and enlargement of the parotid glands which on about 30 percent of males past puberty also results in inflammation of testes
Mumps
The esophagus pierces the diaphragm at the level of
T10
An obviuos notch, located along the lesser curvature of the stomach, closer to the pyloric orifice.
Angular notch or incisura angularis
Is the aperture or opening between esophagus and stomach which is guided my circular muscles of the cardiac sphincter
Esophagogastric junction or Cardiac Orifice
A notch found at the junction of the esophagus and greater curvature of the stomach is termed the
Cardiac Notch or Incisura Cardiaca
Is about 10inches (25cm) ling, and it is the shortest, wides and most fixed portion of the small bowel
Duodenum
The junction of duodenum with the second portion of small bowel, the jejunum is relatively fixed and held in place bh a fibrois muscular band
Ligament of Treitz
A pathologic constricture termed a ___________ is evident at the distal esophagus, a type of hiatal hernia wherein the esophagogastric junction has herniated theough the diaphragmatic opening.
Schatzke’s Ring
Describe Hypersthenic Px
☑️Massive body build
☑️chest and abdomen being very broad and deep from front to back
☑️lungs short and wide
☑️diaphragm is quite high
☑️heart short and wide lies in a transverse axis
☑️transverse colon quite high
☑️entire large bowel extends to the periphery of the abdominal cavity
☑️GB higher and more to the right, almost transverse and lies well away from the midline
☑️stomach bery high and assumes transverse position
Describe Asthenic type of body habitus
☑️extremely slender build
☑️chest cavity narrow, shallow and quite long
☑️diaphragm lies very low
☑️heart long and slender
☑️large bowel found folds on itself, very low, toward the midline
☑️GB & stomach are both low, vertical near midline
☑️abdominal cavity is shallow
Describe Sthenic
☑️average body build
☑️stomach J-shaped and located lower
☑️GB less transverse
☑️splenic flexire of the large bowel is offen quite high, resting under the left diaphragm
Describe Hyposthenic
☑️more slender asthenic build
☑️stomach elongated, J-shape & extends to iliac crest or below
☑️GB is lower and toward the midline compared to sthenic
☑️large bowel is located lower than in average
☑️splenic flexire may still be found hig in ULQ
To demonstrate esophageal varices, the patient must be examined in
Recumbent position

Upper limb venogram
Which of the following radiologic examinations can demonstrate ureteral reflux?
Voiding cystourethrogram
Double-contrast examinations of the stomach or large bowel are performed to better visualize the
Gastric or mucosa
Which of the following structures is (are) most likely to be demonstrated in a right lateral decubitus position of a double-contrast BE?
- Lateral wall of the descending colon
2. Medial wall of the ascending colon
The contrast media of choice for use in myelography are

Which of the following radiologic procedures requires that a contrast medium be injected into the renal pelvis via a catheter placed within the ureter?
Retrograde Urography
During GI radiography, the position of the stomach may vary depending on
- respiratory phase.
- body habitus.
- patient position.
With which of the following is zonography associated?
- 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
use a 15º AP Trendelenburg position.
T-tube cholangiography is performed
