warning

"Noise in CT is measured via the signal to noise ratio (SNR); comparing the level of desired signal (photons) to the level of background noise (pixels deviating from normal). The higher the ratio, the less noise is present in the image."

Line 2:62 · 'SNR' has no definition. Spell it out if it's unfamiliar to the audience.

"2 x mAs = 40% increase SNR"

Line 7:35 · 'SNR' has no definition. Spell it out if it's unfamiliar to the audience.

"The number of photons available to generate an image has a linear relationship to the slice thickness. The thicker the slice, the more photons available; and the more photons available, the better the SNR. However, this is not without a trade-off because increasing the slice thickness will decrease the spatial resolution in the z-axis."

"Noise in computed tomography is an unwanted change in pixel values in an otherwise homogeneous image. Often noise is defined loosely as the grainy appearance on cross-sectional imaging; more often than not, this is quantum mottle."

Line 1:219 · Use semicolons judiciously.

"Noise in CT is measured via the signal to noise ratio (SNR); comparing the level of desired signal (photons) to the level of background noise (pixels deviating from normal). The higher the ratio, the less noise is present in the image."
