Final answer:
The mAs used in routine CT exams of the abdomen can vary depending on factors such as patient size, whether iterative reconstruction is applied, and dose modulation.
Step-by-step explanation:
The mAs used in routine CT exams of the abdomen can vary depending on factors such as patient size, whether iterative reconstruction is applied, and dose modulation. There is no specific predetermined mAs value for routine CT exams of the abdomen. Instead, the mAs is adjusted to optimize image quality while minimizing radiation dose.
