Throughout transmission sound isn't attenuated as much as surrounding tissue |
Acoustic enhancement |
|
|
The opposite of acoustic enhancement. Sound beam is attenuated. |
Shadowing |
|
|
Portions of the image that are not as bright as surrounding tissue. Tissue appears less bright |
Hypoechoic |
|
|
Portions of the image are brighter than surrounding areas tissue that appears brighter than normal |
Hyperechoic |
|
|
Without Echoes, an extreme form of hypoechoic |
Anechoic |
|
|
Structures with equal Echo brightness |
Isoechoic |
|
|
A portion of tissue or an image that has similar Echo characteristics throughout |
Homogeneous |
|
|
A portion of tissue or image that has different Echo characteristics throughout |
Heterogeneous |
|
|
Sometimes used to describe any fluid-filled structure. Gallbladder, bladder |
Cystic |
|
|
Structure with both fluid filled and solid areas |
Complex |
|
|
Mass or organs with low-level Echoes because cellular tissue is acoustically similar |
Solid |
|
|
Front side of a patient |
Anterior, ventral |
|
|
Backside of a patient |
Posterior, dorsal |
|
|
Closer to the origin, or Center of body |
Proximal |
|
|
Away from the origin, or Center of body |
Distal |
|
|
Cranial, cephalid. Towards the head |
Superior |
|
|
Caudal towards the feet |
Inferior, caudal |
|
|
Away from midline |
Lateral |
|
|
Towards midline |
Medial |
|
|
On the opposite side |
Contralateral |
|
|
On the same side |
Ipsilateral |
|
|
What happens in regards to attenuation when acoustic enhancement occurs |
Returning Echoes are stronger and brighter.
Sound has less attenuated. |
|
|
What is another synonym for the term longitudinal |
Sagittal |
|
|
Describes position when a patient lies on their side |
Decubitus |
|
|
Identify the advantages of using a sector transducer |
Small footprint useful for areas of small access. Between ribs and through fontanelle. Good for angling up or for wedging between tight spots cardiac |
|
|
Identify the disadvantages of using a sector transducer |
narrow field of view |
|
|
Identify advantages of using a curved linear transducer |
Much larger field-of-view, good for large structures and overviews. |
|
|
Identify the disadvantages of using a curved linear transducer |
Large footprint, may not fit acoustic window |
|
|
Advantages of using a linear array transducer |
Block shape of image allows for large field of view in The Superficial areas. Excellent for vascular, small parts, renal transplants, subfascial hematomas. |
|
|
Identify the disadvantage of using a linear array transducer |
Can only be used where there is a large acoustic window. Cannot get between ribs. |
|
|
How might Senay Loop be helpful in pediatric Imaging |
Stores a short clip of scanning. Catch a moving Target. Difficult patients. Patients that have difficulty holding their breath |
