Which technique adjustment is necessary for obese patients in radiographic procedures?

For obese patients in radiographic procedures, it is necessary to increase the exposure technique. This is because excess body tissue can absorb more radiation, which may result in underexposed images if the exposure settings are not adjusted appropriately.

Increasing the exposure technique allows for the appropriate penetration of X-rays through the additional adipose (fat) and muscle tissue, ensuring that the radiographs produced are of sufficient quality for diagnostic purposes. Factors such as tube current (mA), exposure time, and kilovoltage peak (kVp) may all be modified to achieve this goal.

Using a correct exposure technique is crucial in ensuring that the radiographic images are adequately captured, avoiding the need for repeat exposures, which can increase patient exposure to radiation unnecessarily and add to workflow inefficiencies.
