Chest Flashcards
Which of the following terms make up the sternum
Body, manubrium, xiphoid process
The lower 5 pair of ribs are called
False ribs
Organs found within the mediastinum
Heart, trachea, ascending aorta
The inferior lateral corners of the lungs are called
Costophrenic angles
When the abdomen is divided into nine regions the lower middle portion is called the
Hypogastric región
The first and proximal portion of the small bowel it is called
Duodenum
When an AP projection of the abdomen is performed the correct SID is
40in
Examination of the chest differs from examination of the ribs in a that
72 inch SID is used
A higher peak kilovoltage is used
An upright AP projection of the abdomen is used ful for the visualization of
Air fluid levels in the intestine
When a PA projection of the chest is performed the correct SID is
72 in
Why are lateral projection of the chest taken with the left side against the IR
Magnification of the cardiac silhouette is minimized with the left side nearer to the IR
Techniques desirable for chest radiography
High kVP , high MA and short exposure time
PA CHEST BODY POSITION
standing facing the IR holder
PA POSITION chest
Anterior surface of the chest is against upright Bucky with coronal plane parallel to ir. Back of hands are placed on hips and shoulders rotated anteriorly or patients can wrap their arms around the Bucky
IR is aligned so that upper margin is 1.5 to 2 in above election the level of spinous process of c7
LATERAL CHEST POSITION
Both arms are raised over head with patient grasping the opposite elbows. Left side of the body is in contact with upright Bucky and midcoronal plane of thorax is perpendicular to the center of IR …IR IS NOT CHANGED FROM PA POSITION
CHEST CENTRAL RAY PA & AP
Pa : Perpendicular to center of IR. Center point should be level of T7 which corresponds to the level of the inferior angle of the scapulae
AP perpendicular to center of IR.center point should be on the midsagittal plane at a level 3 inches below the jugular notch
CHEST LATERAL
CENTRAL RAY
Perpendicular to center of the IR. Center point should be on the midcoronal plane at the level t7
COLLIMATION FOR CHEST X-RAY
Adjust light field to 14 x 17 inches on collimator place side marker in the light field
PATIENT INSTRUCTIONS FOR CHEST X-RAY
Do not move. Stop breathing in second deep inspiration
STRUCTURES SEEN IN CHEST X-RAY
Heart , lungs, and mediastinum
Bony thorax
12 ribs -24 in total
Flat bone
TRUE ribs 1-7
False ribs 8-10
Floating ribs 11,12
The thoracic cavity 3 parts
2 pleural cavities
mediastinum - space between lungs
Trachea wind pipe
Lungs lower surface called base and the angles at the top is called
APEX
