hyperechoic is a mass that has a dark appearance.
A hyperechoic mass in the endocervical canal on ultrasound imaging may indicate the presence of a polyp, fibroid, or other benign growth. Further evaluation, such as a biopsy, may be needed to determine the exact nature of the mass.
A thyroid nodule is simply a mass in your thyroid. Hyperechoic is a term used in ultrasound which determines how bright or dark the nodule is. Ultrasound is all black, white, and gray scales, so a hyperechoic nodule would be a mass in the thyroid that is BRIGHTER than the rest of the thyroid tissue.
A hypoechoic mass is a lump which appears darker on an ultrasound scan. These darker areas on an ultrasound scan are suggestive of a tumor.
This is A SOLID MASS o the lining of the uterus
An isoechoic mass in the uterus is a mass that has the same density as the uterine tissue. This is most often a fibroid. Talk with your health care provider for advice specific to your situation.
The oxide N2O3 has a lower percent of mass nitrogen.
Cobalt has an atomic mass of 58.933195(5) while nickel has an atomic mass of 58.6934(4). Nickel has the lower atomic mass.
A circle is a 2-dimensional plane figure composed of a line segment on which every point is the same distancefrom a single point that is not on the line segment. As such, a circle has area but no mass.
lower mass = higher frequency
Interestingly, nickel has a lower atomic mass (58.693) than cobalt (58.933), even though cobalt has a lower atomic number (27) than nickel (28).
The inertia of an object is directly proportional to its mass. The greater the mass the greater the inertia and the lower the mass the lower the inertia. This tells us the fat person will have more inertia due to his greater mass and the thin person will have less inertia due to his lower mass.
