What group of exposure factors would be most appropriate for a sthenic adult undergoing IVU?

The combination of exposure factors listed represents a well-balanced approach for imaging a sthenic adult during an Intravenous Urogram (IVU). In imaging, kVp (kilovolt peak) is crucial for penetrating the tissues effectively, ensuring that sufficient contrast is achieved without compromising image quality.

For this scenario, the selected exposure factors of 300 mA, 0.02 s, and 72 kVp align nicely with the principles of adequate exposure while considering patient safety and image clarity. The mA value of 300 indicates a higher amount of current, which increases the quantity of X-ray photons produced. This is particularly beneficial for a procedure like an IVU, where contrast media enhances visualization of the urinary tract.

The duration of exposure is also a key factor, and 0.02 seconds strikes a reasonable balance between minimizing motion blur, especially in a sthenic adult whose body may require slightly more exposure time to capture a clear image without overexposing the patient to unnecessary radiation.

The kVp at 72 provides sufficient penetration for soft tissue imaging while ensuring that the contrast media can be adequately visualized. This is important as the IVU specifically aims to highlight the urinary system.

In summary, this set of exposure factors
