Radiographic Procedu

Body Types, Anatomy, Bones, GI Exams, etc.

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
