Sonographic Image Flashcards
has low-level echoes with a good posterior border
hypechoic
bright echo reflectors and posible shadowing
may represent a tumor, thrombus, or calcification
hyperechoic
same texture pattern as the surrounding paenchyma with no significant change in the through transmission
isoechoic
shows no internal echoes, has smooth wall, and displays increased through transmission
anechoic
generally includes a survey of the abdominal cavity from the diaphragm to the levle of the umbilicus
abdominal and retroperitoneum
is performed in the transverse, oblique, sagittal, coronal, and subcoatal planes
abdominal scanning
evaluated to assess the size and homogeneity of the parenchymal tissue which are normally unifrom or homogeneous
liver and spleen
texture depends on the amount of fat interspersed throughout its islet of langerhans
pancreas
includes the gallbladder and bile ducts which are evaluated to assess the size and wall thickness of these structures in detecting sludge, stones, polyps, or other masses
bilary system
are assesed for size dilation of calyces structures, abnormal texture patterns, tumors, abscesses, infarcts, hematomas, or infiltrative processes
kidneys
real-time evaluation may demonstrate enlargement within homogenous texture (goiter), a solid mass with a halo surrounding its border (adenoma) or solid mass with poorly defined borders (carcinoma)
thyroid
characterized the texture of a breast mass to determine whether the mass is fluid-filled, complex, or solid. Can also demonstrate minute structure such as lactiferous ducts
breast
ultrasound can demonstrate minute structures such as lactiferous ducts in the spermatic cord within the testes
scrotum
a high-frequency transducer is inserted into the vagina to image these structures
ovaries-uterus-cervix-vagina-fallopian tubes
gestational sac - embry yolk sac - amniotic cavities
edovaginal ultrasound
gestation sac seean as early as
4 weeks
