Radiologic Physics RADT 100 Anatomy of the
Mediastinum and Body Quadrants
1. What is the name of the area between the two pleural cavities?:
Mediastinum
2. Which structure is not demonstrated within the mediastinum in PA
projec- tions of the chest?: Diaphragm
3. Which pathologic condition of the lung involves the replacement of
air with fluid in the lung interstitium and alveoli?: Pulmonary Edema
4. Why should chest images be performed with a 72" SID?: To minimize
magni- fication of the heart
5. Why should chest images be performed after the patient has
suspended respiration after the 2nd inspiration?: To expand the
lungs better
6. With reference to the IR, how are the midsagittal plane and the
midcoronal plane positioned for the PA projection of the chest?:
Midsagittal----Perpendicu- lar
Midcoronal----
Parallel
7. For the Pa projection of the chest, which positioning maneuver
should be performed for the best removal of the scapulae from the
lung fields?: Rotate the shoulder forward
8. Why would the chest most likely be demonstrated using two PA
projections (in which the patient is seen in suspended inspiration and
suspended expira- tion)?: To demonstrate pneumothorax
,9. Which of the following is an effective way to detect rotation of the
patient with the PA projection image of the chest?: The asymmetrical
appearance of the sternoclavicular joints
10. For which projection of the chest should the midsagittal plane be
parallel with the IR?: Lateral Projection
11. With reference to the IR, How are the midcoronal plane and the
midsagittal plane positioned for the lateral projection of the chest?:
Midcoronal---Perpen- dicular
Midsagittal---
Parallel
12. Which projection of the chest best demonstrates lung apices
free from superimposition with the clavicles?: AP Axial Projection
Left Lateral Decubitus
Position
13. Which PA oblique projection of the chest may be used to evaluate
the heart and great vessels when performing a cardiac series?: 55-60
degree LAO
14. 4 types of body habitus?:
