lecture 2 Flashcards
black on ultrasound
fluid, waves absorbed
white on ultrasound
tissue, waves bounced back
ultrasound of thoracic cavity looks at
pleural space, pleural lining, heart
ultrasound of abdominal cavity looks at
peritoneal space, internal organs
solid structures looked at using ultrasound
tendons, ligaments, tumors, masses, abscesses
low frequency ultrasound is used for
looking further into structures, able to penetrate tissues better ex. looking into abdomen
high frequency ultrasound is used for
looking at fine structures close to skin ex. looking at tendon
acoustic shadow is caused by
bone or mineral
dirty acoustic shadow
looks hazy, unable to view further than object creating shadow, makes stomach/colon/lungs hard to see through
clean acoustic shadow
stark/has clean edges, unable to see deeper objects, makes kidneys and brain hard to view
main variables quantified in fetal monitoring are indicators of what condition and what causes that condition
fetal hypoxia which results from inflammation or placental separation
variables observed during fetal monitoring
tachy or bradycardia, heart rate, frequency and type of musculoskeletal movement, breathing movements, volume and character of fetal fluids, placental thickness/separation/edema
what are B lines and what is its most common cause
abnormal artifact seen commonly in lungs as full bright white lines, most common cause is pneumonia
ultrasound findings with enterocolitis
thick small intestinal walls, mural diameter increased by fluid distension, gastric enlargement, duodenal dilation, liquid luminal contents in small/large intestine
how is enterocolitis treated
enforced mucosal rest with nutritional support
