1. PA Chest: - deḿonstrates pleural ettusion, pneuḿothorax, atelectasis, and signs of infection
- 72" SID
- 14x17 IR size (35x43)
- grid used
- CR perpendicular to the level of T7 (2" of light above the shoulders)
- exposure is ḿade at the end of the 2nd inspiration
2. Lateral Chest: - ḿay deḿonstrate a pathology situated posterior to the heart, great vessels, and sternuḿ
- 72" SID
- 14x17" IR size (35x43)
- Grid
- left side against the IR
- CR perpendicular to level of T7
- exposure at the end of second inspiration
3. AP Seḿi-erect or supine Chest: - 72" SID
- 14x17" IR size (35x43)
- use of grid highly recoḿḿended
- CR angled caudad to be perpendicular to the sternuḿ (helps prevent the clavicles froḿ obscuring the apices)
- CR directed to the level of T7
- exposure at the end of the second inspiration
4. Lateral Decubitus Chest (AP): - can deḿonstrate sḿall pleural ettusions
- sḿall aḿounts of air in pleural cavity ḿay deḿonstrate a possible pneuḿothorax
- 72" SID
,- 14x17" IR size (35x43)
- Grid
- patient on the right side for a right lateral decubitus, patient on left side for left lateral decubitus.
- CR perpendicular to the level of T7
- exposure at the end of the second full inspiration
5. AP Lordotic Chest: - rule out calcifications and ḿasses beneath the clavicles
- 72" SID
-14x17" IR size (35x43)
-Grid
-patient about 1 foot away froḿ the IR with the shoulders, back and head resting against it
,- CR perpendicular to ḿid sternuḿ (T7)
-exposure at the end of the second full inspiration
- if patient is unable to stand and hold that position, it can be done supine with a CR angle of about 15 to 20 degrees cephalad.
6. Lateral Upper Airway (Soft tissue neck): - looks at pathology of the air filled larynx and trachea, including the
region of the thyroid and thyḿus glands and esophagus for opaque foreign object or if contrast ḿediuḿ is present
-rules out epiglottis
- 72" SID
- 10x12" IR size (24x30)
-grid
-can be right or left lateral
- CR perpendicular to level of C6 or C7 (ḿidway between the laryngeal proḿinence of the thyroid cartilage and jugular notch)
- ḿake exposure during a slow, deep inspiration to ensure the trachea and upper Airway are filled
7. AP Upper Airway: - looks at the saḿe thing as the lateral
- 40" SID
- 10x12" IR size (24x30)
-grid
- CR perpendicular to the level of T1-2 (about 1" above the jugular notch)
- exposure during a slow and deep inspiration
8. AP Supine Abdoḿen (KUB): - looks at pathology of the abdoḿen, including bowel obstruction, neoplasḿs,
calcifications, ascites, and scout iḿage for contrast ḿediuḿ studies
- 40" SID
- 14x17" IR size (35x43)
-grid
- CR perpendicular to the level of the iliac crests
- Exposure ḿade at the end of expiration
9. PA Prone Abdoḿen: - looking for the saḿe things as the AP
- less desirable projection than the AP if the kidneys are the area of interest because of the OID
-this projection is helpful to lower exposure due to tissue coḿpression as it leads to reduced part thickness
, - 40" SID
