fluoroscopy evals Flashcards
PA stomach
why do we do it?
when a patient lies down compression on the stomach will push the barium up to the fundus as well as down to the pyloric region as well as the duodenum, showing us the entire stomach
why would we do a PA/AP stomach standing?
doing the projection standing will show use the size and shape of the stomach.
we wont see the fundus however since the stomach will drop 1.5 to 4 inches when standing
PA OBLIQUE stomach
why do we do it
provides the best visualization of the pyloric canal and duodenal bulb
*in sthenic patients
this is due to the RAO position stimulating gastric peristalsis the most
fun fact
* several exposures can be made in 30 to 40 second intervals to better outline the pyloric canal and duodenal bulb
PA OBLIQUE stomach (2)
eval
*no superimposition of the pylorus and duodenal bulb
*duodenal bulb and loop in profile
AP OBLIQUE stomach
what do we see
will show us the fundus as the LAO position will push the barium to the left side away from the pyloric region.
this pushes the air down towards the pyloric region giving us a double contrast look
AP OBLIQUE stomach
eval (2)
no superimposition of pylorus and duodenal bulb
Because the contrast is pushed up to the fundus we will see the body of the stomach and pylorus and pyloric antrum with dual contrast visualization
LAT stomach
what do we see
provides the best visualization of the pyloric canal and duodenal bulb
*in hypersthenic patients
LAT stomach
standing vs recumbent
standing: is a left lateral and shows us the left retro gastric space of the stomach
recumbent: right lateral and shows us the right retro gastric space of the stomach
LAT stomach
eval
*anterior and posterior aspects of the stomach
*right retro gastric space of the stomach
*pyloric canal and duodenum loop (pushes the contrast down)
AP stomach
SS
shows us the
*retro gastric portion of duodenum and jejunum
* hernias in the diaphragm
PA/AP small intestines
SS
Contrast filled small intestine until barium reaches ileocecal valve
PA/AP small intestines
evals
- stomach included on the first image
*centered vertebral column
PA large intestines
eval
used to see entire colon to include both flexures and the rectum
PA/AP Obliques large intestines
ss
if right side is of interest
*cecum
*ascending
*hepatic flexure
*sigmoid
if left side is of interest
* descending
*splenic flexure
Lateral large intestines
ss
*to view the rectum and sigmoid
