ABD OVERVIEW Flashcards
Normal echogenicity of abdominal organs from brightest to darkest
renal sinus, pancreas, spleen, liver, renal cortex, renal pyramids, gallbladder
What is the STAR criteria for a simple cyst
smooth walls, demonstrate through transmission, be completely anechoic and round in shape
Patients who have some form of “itis” or possible even an abscess will most likely have an
abnormal WBC count with existing infection
Higher frequency equals
higher resolution, lower penetration
Lower frequency equals
lower resolution, higher penetration
Occurs when the sound beam strikes a structure in a non perpendicular manner, resulting in a loss if the true echogenicity of the structure
anisotropy
Blood returning from the heart from the system circulation is via the
SVC and IVC
The SVC and IVC empty into the
right atrium
What is the typical pattern of blood flow
arterioles, capillary, venule, vein
______ release their hormones directly into the bloodstream
endocrine glands
______ release their enzymes through ducts
exocrine glands
What are the endocrine organs or structures
adrenal glands, liver, ovaries, pancreas, parathyroid glands, pineal gland, pituitary glands, testicles, thyroid gland
What are the exocrine organs or structures
breast, pancreas, salivary glands, liver
A build up of lymphatic fluid caused by obstruction of this drainage process with subsequent swelling
lymphadema
Enlargement of lymph node
lymphadenopathy
The largest mass of lymphatic tissue is the
spleen
GALT stands for
gut-associated lymphoid tissue
BALT stands for
bronchus-associated lymphoid tissue
Consists of parietal and visceral layer
peritoneum
Structures only covered anteriorly with peritoneum
retroperitoneal
The word blast refers to
childhood malignancy
What are the intraperitoneal organs
gallbladder, liver (minus bare area), ovaries, spleen (except hilum), stomach
What are the retroperitoneal organs
abd lymph nodes, adrenal glands, aorta, ascending and descending colon, duodenum, IVC, kidneys, pancfreas, prostate gland, ureters, urinary bladder, uterus
anemia
a condition in which the red blood cell count or the hemoglobin is
decreased
chromaffin cells
the cells in the adrenal medulla that secrete epinephrine
17
and norepinephrine
coagulopathies
disorders that result from the body’s inability to coagulate
or form blood clots also referred to as bleeding disorders
exudate ascites
a collection of abdominal fluid within the peritoneal cavity
that may be associated with cancer
gastrin
hormone produced by the stomach lining that is used to regulate
the release of digestive acid
kaposi sarcoma
cancer that causes lesions to develop on the skin and
other places; often associated with AIDS
morrison pouch
the space between the liver and the right kidney; also
referred to as the posterior right subhepatic space
