Chest, Abdomen and Ribs Flashcards
why do we do chest radiography?
to visualize visceral anatomy of chest (heart and lungs)
what kVp is required for chest?
high
SID chest radiography
72”
routine chest series
PA chest
left lateral chest
set up flow
measure set control panel set SID set collimation and apply side marker apply lead shielding to patient position patient at bucky align cassette to patient align CR to center of cassette
film size PA chest
14x17
bucky placement
1 1/2” above VP
ID blocker (PA chest)
up
CR (PA chest)
to spine and mid film
collimate (PA chest)
to film size
marker (PA chest)
Left above left shoulder
patient instructions (PA chest)
roll shoulders forward
deep inspiration adn hold
measure (PA chest)
over shoulder, spine to mid sternum
what should you see on PA chest?
tracheal air shadow aortic knob/arch cardiophrenic angle diaphragm hilum apex
optimal PA chest criteria
all heart and lung anatomy included unwanted anatomy out of lungs no rotation adequate penetration of structures upper 4 thoracic vertebrae identified well adequate inspiration of lung count 10 posteiror or 7 anterior ribs lung markings are crisp
SID (L lateral chest)
72”
film size (L lateral chest)
14x17
bucky location (L lateral chest)
1 1/2” above VP
patient position (L lateral chest)
left side against bucky, hands over head
CR (L lateral chest)
center of film and mid-axillary line
marker (L lateral chest)
left marker above left shoulder
breathing instructions (L lateral chest)
deep inspiration and hold
things you should see (L lateral chest)
sternum heart right hemidiaphragm left hemidiaphragm posterior costophrenic angles superimposed aortic arch apices superimposed
image criterial (L lateral chest)
apices through costophrenic angles visualized and clear
posteior ribs superimposed
IVFs open
sternum in profile
abdominal routine series
recumbent or upright AP abdomen
why do we take a recumbent AP abdomen
rule out masses, aneurysm, calcifications, foreign bodies, fetal shadows, bowel gas pattern
if an aneurysm is suspected, what must you also take?
lateral abdomen
why do we take an upright AP abdomen
identify free air in abdominal cavity
air fluid levels
patient postion for recumbent AP abdomen
supine on table bucky
film size adn position for recumbent AP abdomen
14x17, vertical
CR (recumbent)
iliac crest
breathing instructions for recumbent
exhale and hold
what do we need to see on a recumbent?
bottom of bladder
measure for abdomen films
largest part of abdomen
film size and position (upright)
14x17
top of cassette at axilla level
2”above crest
what must an upright include?
diaphragm
breathing instructions (upright)
expiration
what may we see on upright?
chest, diaphragm
meganblas
unilateral AP rib SID
40”
unilateral AP rib cassette
14x17 vertical
unilateral AP rib, where does injured part go?
closest to bucky
unilateral AP rib (upper) cassette position
top of cassette 1 1/2” above VP
unilateral AP rib (lower) cassette position
bottom of cassette at crest
CR unilateral AP rib
CR to mid film
vertical cross hair on other side of sternum
unilateral AP rib (upper) breathing
inspiration
unilateral AP rib (lower)
expiration
bilateral AP ribs cassette (upper)
14x17 transverse
top of cassette 1 1/2” above shoulders
bilateral AP ribs cassette (lower)
14x17
transverse
bottom of cassette at crest
bilateral AP ribs cassette (upper)
inspiration
bilateral AP ribs cassette (lower)
expiration
