C. The scenario described when a 7 Tesla scanner, or 7T scanner is used instead of 3T scanner is, "when higher pixel resolution is required"
<h3>What is pixel resolution?</h3>
Pixels per inch and pixels per centimeter are measurements of the pixel density of an electronic image device, such as a computer monitor or television display, or image digitizing device such as a camera or image scanner.
A 7 Tesla scanner, or 7T scanner is preferable to a 3T scanner because the 7 Tesla scanner gives higher pixel resolution when compared to 3 Tesla scanner.
Thus, the scenario described when a 7 Tesla scanner, or 7T scanner is used instead of 3T scanner is, "when higher pixel resolution is required".
