Question

Quizplus · Accepted Answer

The angle of the central ray for the mediolateral oblique (MLO) projection of the breast can vary between 30 to 60 degrees, depending on the angle of the pectoral muscle. This projection is done by placing the patient in a standing or sitting position, leaning forward with one shoulder rotated forward while the other shoulder is pulled back, and the x-ray machine angled from above towards the breast at an angle that best visualizes the breast tissue and pectoral muscle. This angle can vary from patient to patient, but typically falls within the range of 30 to 60 degrees. Choices A, B, and D do not accurately reflect the range of angles used for this projection.
