X-Ray
This is the two-forearm version of the standard front-and-side study, imaging the radius and ulna in each arm during the same visit. It gets ordered when an accident, often a fall from a two-wheeler or a similar collision, injures both arms at once and each one needs its own check for a break in the radius, the ulna, or both. This is a less common request than a single-forearm study, since most forearm injuries involve just one side. A doctor may also order both arms together while tracking a bone-growth condition that affects a child symmetrically, though that reason comes up far less often than shared trauma.
Each forearm gets its own front and side view, covering the radius and ulna on both sides in one visit. The films are read separately for each arm's bone length, alignment, and angulation, then compared if your doctor is checking for a symmetric pattern rather than two unrelated injuries.
Both forearms rarely break at once by chance, so when this test is ordered, it is almost always because a single accident, a fall from a moving vehicle, a road collision, or a fall onto both outstretched hands, has affected both arms together.
Even though both arms are imaged in one visit, each forearm is read independently first, checking the radius and ulna for length, angle, and alignment the same way a single-arm study would. Only after that does a doctor compare the two sides against each other.
Some bone-growth conditions affect both arms in a similar pattern as a child grows, and a doctor following one of these may want both forearms imaged at the same visit to track how closely the two sides are staying matched over time. This use comes up far less often than the trauma reason above.
This is usually ordered after a single accident, such as a fall from a two-wheeler, injures both arms together. Each forearm still gets its own front and side view and is read on its own terms.
Each arm receives the same low dose as a single-forearm study, just doubled because two arms are being imaged. The centre uses the lowest amount needed for a clear image on each side.
Yes, each forearm is positioned separately for its own front and side view, the same way a single-arm study is taken, so both results are directly comparable.
Yes. Even when both arms are hurt in the same accident, it is common for the injuries to differ in severity, and each arm's X-ray is read independently to tell the difference.

That depends on what your doctor finds and how each fracture is being treated. Ask your doctor what follow-up imaging, if any, they expect to need.
Yes, falling onto both outstretched hands during a two-wheeler accident is one of the more common reasons both forearms end up being checked in the same visit.
Yes, tell the technologist which side feels worse, since this can help guide how the exam is prioritized and positioned.
