RP&P Test 1
Radiographic Positioning & Procedures Ch. 2-3
| Term | Definition |
|---|---|
| T1 | Approx 2 inches (5cm) above the level of the jugular notch |
| T2 T3 | level of jugular notch |
| T4 T5 | level of sternal angle |
| T7 | level of inferior angles of scapulae; used as a landmark for chest x-rays |
| T9 T10 | Level of xiphoid process |
| L2 L3 | inferior costal margin |
| L4 L5 | Level of superior-most aspect of iliac crests |
| S1 S2 | level of anterior superior iliac spine (ASIS) |
| Coccyx | Level of pubic symphysis and greater trochanter |
| SID | source to image distance; important to avoid distortion of image |
| 72 inches | SID for PA chest |
| 10 Ribs | marker for quality of image; 10 ribs need to be seen in the image field |
| AP Projection | CR enters anterior body and exits posterior body |
| PA Projection | CR enters posterior body and exits anterior body |
| Lateral Projection | perpendicular CR enters lateral surface and exits opposite lateral surface of part/body |
| PA - Upright/Sitting | roll shoulders forward to move scapula from lung fields; visualize 10 posterior rubs within the lung fields/above diaphragm |
| Left Lateral - Upright | arms above lung field; midsagittal plane is vertical and parallel to the image receptor; the ribs posterior to the vertebral column should be superimposed/overlapping; sternum should be lateral; Left side to IR to reduce magnification of the heart |
| AP Supine | Used when PA upright/standing is not an option; CR is 3" below jugular notch; heart is magnified due to an inability to obtain 72" SID |
| Apical Lordotic (Lindblom Method) | Lordotic position; CR enters at mid-sternum - about 3-4 inches below the jugular notch |
| AP Axial | 15-20 degrees cephalic; CR is at the manubrium; done if the patient is unable to do the lordotic; elongates apices |
| Lateral Decubitus | Air vs. fluid levels; fluid side down, air side up; Mark It Side Up, Call It Side Down; CR 3 inches below the jugular notch; propped up with 2-3" of foam |
| Pneumothorax | air in the pleural cavity |
| Atelectasis | partial collapse of one or more pulmonary lobes |
| Pleural Effusion | Fluid in the pleural cavity |
| Thoracentesis | procedure used to draw fluid from the pleural cavity |
| Carina | Bifurcation of the trachea (T5); ET tube is properly positioned at the level of 1-2" superior to the Trachea Bifurcates |
| Apices | located where the upper lobe begins; top of the lung near the clavicles |
| Costophrenic Angle | angles that are formed by the points at which the chest wall and diaphragm meet |
| Cardiac Angle | the angle between the heart and the diaphragm |
| Aortic Notch | the top part of the main artery carrying blood away from the heart |
| Hilum | an indentation in the surface of a kidney, spleen, or other organ, where blood vessels, ducts, nerve fibers, etc. enter or leave it |
| Sagittal Plane | divides the entire body or body part into right and left segments |
| Coronal plane | divides the entire body or body part into anterior and posterior segments |
| Oblique plane | can pass through a body at any angle along the coronal or sagittal plane. |
| Horizontal Plane | passes crosswise through the body or body part at right angles to the longitudinal axis |
| Bursae | a fluid-filled sac or saclike cavity, especially on countering friction at a joint |
| Ipsilateral | part or parts on the same side of the bod |
| Recumbent | General term referring to lying down in any position such as dorsal recumbent, ventral recumbent, or lateral recumbent |
| Oblique Position | when the entire body or body part is not parallel with the radiographic table or IR; some rotation |
| Decubitus Postiton | Laying down with the CR horizontal and parallel to the floor |
| Position | placement of the body part |
| Projection | how the body part is being viewed |
| View | body part as seen by the IR: the image; not the same as projection |
| TAE | Trachea is Anterior to the Esophagus |
