Echogenic
- Tissue that produces echoes Hyperechoic - Producing
echoes of higher amplitude and/or density than for the
surrounding medium. Hypoechoic
-
Producing
echoes of lower amplitude and/or density than for the surrounding medium. Sonolucent
- No echoes -
minimal attenuation (a clear cyst) Anechoic
- Echo free or without echoes. (A clear cyst is
anechoic.) Transonic
- No echoes - or echo free Ultrasound
Window
- Using part of the existing
anatomy to "see through"another part of the anatomy)'. Shadowing
-
No transmission of sound -
sound is reflected where
shadow is
located. Enhancement
-
An
increased amplitude of echoes beginning at the posterior wall and
proceeding distally. (i.e. tissues posterior to a cyst.) Display
Format
- The
manner in which information is presented to the Insonation
- The act of exposing a target tissue to ultrasonic
energy Lung
Interference Poor
Acoustical Window Amorphous
tissue - Tissue lacking
echo-producing structures, (acoustical definition} Noise
-
A
signal conveying unwanted information, often detracting from the
intelligibility of other signals. Artifact
- An apparent echo for which distance, direction or
amplitude do not correspond to a real interface. Suprasternal
window (for imaging the aorta in
coarctation Parasternal
- Parasternal Long Axis – or
Sagittal or long axis Parasternal

transverse Apical Apical

Valves – Aorta & Pulmonary Atria
Ventricular Vales – Tricuspid & Mitral vales Definity Use Guidelines for the Presbyterian University Hospital Echo Lab
1. Exclude cardiac patients: · On the coronary care unit team service · Acute chest pain patients for example in the ER or cardiac Pavilion · Patients with positive cardiac markers for myocardial infarction (CPKs or troponins) on the day of the echo · Patients with acute CHF · Patients with known intracardiac shunts 2. Exclude pulmonary patients as follows: · Ventilated patients · Those with respiratory distress (defined as anyone needing supplemental oxygen) · Patients with severe emphysema or acute asthma · Pulmonary embolism during a currant admission · Tricuspid regurgitant velocity > 3.5 m/sec 3. Patients with: · Serious ventricular arrhythmias · High risk for ventricular arrhythmias due to prolonged QT interval. · Patients with stable rhythms who have an AICD do not have to be excluded
