TRACHEA

Question 1

PP: Supine/upright; neck slightly extended; MSP ┴
to IR; Adjust pt.shoulders to lie in the same
transverse plane; Center IR at the level of the
manubrium; exposure during slow inspiration;
RP: Manubrium
CR: ┴ through the manubrium to the center of the IR
SS: Outline of the Air-filled trachea; Area from the
midcervical to the midthoracic region.

Answer 1

AP PROJECTION

Question 2

PP: Seated/upright lateral position; hands clasped
behind the body; shoulder rotated posteriorly
(prevents superimposition of arms & superior
mediastinum); neck extended slightly; exposure
during slow inspiration
RP: Midway b/n jugular notch & midcoronal plane
(for trachea); 4-5 in. lower (for superior
mediastinum)
CR: Horizontal though a point of midway bet. The
jugular notch and the MCP
SS: Air-filled trachea &trachea and superior
mediastinum free from superimposition y the
shoulders
ER: described by Eiselbeg & Sgalitzer
* Used to demonstrate restrosternal extensions
of the thyroid gland
* Thymic enlargement in infants (recumbent
position)
* Opacified larynx & upper esophagus
* Outline of trachea & bronchi
CI: Aspiration/ For foreign body localization

Answer 2

LATERAL PROJECTION

Question 3

PP: Seated/Upright; affected side toward the IR;
elevate the arm adjacent to IR in extreme abduction,
flex elbow,place foream across or behind the head;rest shoulder firmly against IR; depress the opposite
shoulder as pos. body in true lateral position.
RP:
CR:15 deg caudad directed to the center of IR
through the adjacent supraclavicular impression
SS: Air-filled trachea; Shoulders well separated
from each other; area from mid-cervical to
midthoracic region
CI: visualize subluxation and fractures involving
the inferior cervical spine, superior thoracic spine
and adjacent soft tissue

Answer 3
