Question | Answer |
---|---|
Asthenic | body is slender and light, bony framework is delicate, long narrow thoraxis smaller in the extreme, with a long thorax; a very long, almost pelvic stomach; and a low medial gallbladder. The colon is medial and redundant |
Hyposthenic | somewhat lighter, less robust than Sthenic, similar to asthenic but stomach, intestines and gallbladder are situated higher in abdomen |
Sthenic | most predominant type, athletic build, average, similar to hypersthenic but modified by elongation of abdomen and thorax |
Hypersthenic | the very large individual with short, wide heart and lungs; high transverse stomach and gallbladder; and peripheral colon |
With the AP oblique projections (RPO and LPO positions), which kidney is perpendicular and which kidney is parallel | the kidney that is farther away is placed parallel to the IR, and the kidney that is closer is placed perpendicular to the IR. |
The lateral C-spine demonstrates | apophyseal joints, intervertebral disk spaces, and spinous processes |
The stomach is normally angled | with the fundus lying posteriorly |
What is the position of the the body, pylorus, and duodenum | inferior to the fundus and angled anteriorly |
The posterior oblique positions (LPO and RPO) of the lumbar vertebrae demonstrate the apophyseal joints | closest to the IR. |
The Lateral L-Spine best demonstrates | the intervertebral disk spaces, intervertebral foramina, and spinous processes |
45 degree oblique of L-Spine demonstrates | Apophyseal Joints |
The thoracic apophyseal joints are | 70° to the MSP and are demonstrated in a steep (70°) oblique position |
Lateral T-spine best demonstrates | intervertebral disk spaces and intervertebral foramina |
Ampiarthrotic joint | partially movable joint |
Synarthrotic joints | are immoveable |
What groups of organs/structures are located in the left upper quadrant | are the fundus of the stomach, the left kidney and suprarenal gland, and the splenic flexure |
The tangential ("sunrise") projection is used to demonstrate | the articular surfaces of the femur and patella. *****It is also used to demonstrate vertical fractures of the patella. |
The AP oblique projection (medial rotation) of the elbow | superimposes the radial head & neck on the proximal ulna. It shows the olecranon process w/in the olecranon fossa, also projects coronoid process free of superimposition. |
The radial head is projected free of superimposition | in the AP oblique projection (lateral rotation) of the elbow |
Free air in the abdominal cavity is best visualized when the patient is | left lateral decubitus or erect AP |
A dorsal decubitus projection of the chest may be used to evaluate | small amounts of fluid in the posterior chest |
How is the Dorsal Decubitus position obtained | with the patient supine and the x-ray beam directed horizontally |
The RAO position in an Upper GI series best demonstrates | pyloric canal and duodenal bulb along with; the barium-filled esophagus, projecting it between the vertebrae and the heart |
The recumbent AP with slight left oblique best demonstrates | a double contrast of the pylorus and duodenum |
Parts of Sternum | Manubrium most proximal part(4 sides), Body or Gladiolus middle portion, Xiphoid Process or Ensiform most distal |
Thoracic Cavity is lined by | serous membranes called pleura |
Two Pleura walls | parietal (outer), visceral (inner). Parietal lines the thoracic cavity. Visceral is reflected over the surface of the lungs and projects between the fissures |
When examining ribs, in oblique positions which portion will be demonstrated | which ever side is closest to film. |
To demonstrate the ap oblique projection of the SI Joints | the affected side must be elevated 25 degrees |
AP oblique SI Joint places the joint | perpendicular to IR and parallel to CR. |
Anterior oblique projections of a Upper GI study will open up which flexure and colon | The flexure and colon closest to the film |
Posterior oblique projections of a Upper GI study will open up which flexure and colon | the flexure and colon furthest from the film |
Articular facets form | Apophyseal Joints |
Intervertebral joints are well visualized in | the lateral projections of all the vertebral groups |
Male pelvis | • Heavy and thick general structure • Greater, or false, pelvis is deep • Pelvis brim, or inlet, is small and heart-shaped • Acetabulum is large and faces laterally • Pubic angle is less than 90° • Ilium is more vertical |
Female pelvis | • Light and thin general structure • Greater, or false, pelvis is shallow • Pelvis brim, or inlet, is large and oval • Acetabulum is small and faces anteriorly • Pubic angle is more than 90° • Ilium is more horizontal |
Vertebral groups that form Lordotic curves | Cervical and Lumbar |
Vertebral groups that form Kyphotic curves | Thoracic and Sacral |
With oral administration, barium sulfate suspension would first pass through | the upper GI tract—mouth, pharynx, esophagus, stomach (fundus, body, pylorus), small bowel (duodenum, jejunum, ileum), large bowel (cecum, ascending colon, right colic/hepatic flexure), transverse colon, left colic/splenic flexure, & desc colon, sigmoid |
Intervertebral Foramina are formed by | vertebral notches of the pedicles. |
A single-contrast examination demonstrates | the anatomy and contour of the large bowel, as well as anything that may project out from the bowel wall eg, diverticula |
The articular facets (apophyseal joints) of the L5–S1 articulation form | a 30° angle with the MSP; they are therefore well demonstrated in a 30° oblique position |
Which of the following sequences correctly describes the path of blood flow as it leaves the left ventricle | Arteries, arterioles, capillaries, venules, veins |
The contraction and expansion of arterial walls in accordance with forceful contraction and relaxation of the heart is called | pulse |
Performance of the Valsalva maneuver fill | the larynx and trachea with air, which is well demonstrated on soft tissue study |
