Can Barium Swallow Test diagnose SMALL tear in Esophagus? How much mSV radiation do you get from this test? I''m not getting straight forward answers.

No diagnostic. test, including Barium Swallow, is 100%. There are always false negatives. Amount of radiation depends on how many seconds of fluoroscopy is used during the exam. Tears in the esophagus, if full thickness, manifest as mediastinitis within several hours. If partial thickness, it can cause hemorrhage. Sounds like you have neither. Ask your doctor if you really need this test.

Which is better test to Dx small tear in esophagus due to impact? CT, MRI, or barium swallow test?

I prefer barium swal. I was trained to use barium swallow for esophageal tears. However, it is bad to use if the tear penetrates through full thickness of the wall. For this we may use a water soluble contrast. CT is an excellent tool for this but uses a lot of radiation. I would use this if there are complications to worry about or the initial swallow is non diagnostic. MRI is not good. Read more...

Tear/leak in. esophagus is probably best demonstrated by contrast esophagram. Mediastinitis is probably best demonstrated by chest CT. But diagnostic tests are never 100%. False negatives occur with finite incidence and false postives too. That is why one needs to get diagnostic tests only when they are clinically indicated. Read more...
