Test 2: Xray Flashcards
what is a radiograph
photons emitted, pass through the patient, get attenuated and then hit the detector plate
2D image of a 3D structure
5 opacities of XRays
what will be the most white on an xray
metal
as physical density increases what happens to the photons?
more photons gets absorbed, less photons make it to xray plate → white
increase in radiopacity
opposite of radiopacity
radiolucency
Xrays are named based on ___
which side of the patient is down
this is right lateral
(right side is on table)
photons go from left to right side
V→D
____ structures of the same opacity touch and their margins are lost
silhouetting
____ when parts of the patient in different planes are superimposed, the overlapping region of the superimposed objects summate and that region has an increased opacity
summation
example of what
silhouetting, margins are blurred between two things with similar opacities
space overlapped demos what?
summation
two things overlap and give greater opacity (more white)
liver
spleen
left kidney
which kidney is more caudal
left kidney
urinary bladder
the urinary bladder is ventral or dorsal to the rectum?
ventral
stomach, cranial abdomen
small intestines
colon
cecum (ilium to ascending colon)
find liver
find spleen
find Left kidney
find bladder
find stomach
fundus has gas inside
find colon
find cecum
lung lobes on xray
trachea
find heart
trachea end at the ___
carina
aorta
caudal vena cava
caudal vena cave comes through what part of the diaphragm?
right crus of the diaphragm
The caval foramen is located at the junction of the tendinous and muscular parts of the right side of the diaphragm. The caudal vena cava passes through it.
diaphragm
more cranial cura of diaphragm will be the side that is laying down
on R lateral, more cranial crua will be the R cura
left cranial lung lobes
left caudal lung lobes
right cranial lung lobe
right caudal lung lobe
accessory lobe of lung
on right lung
part of lung
trachea
aorta
caudal vena cava
cranial mediastinum
lungs
crus of diaphragm
top of diaphragm
cupula
