Specializes in Diagnostic Radiology

Doesn't make: sense. If the doc was seriously considering aortic dissection, imaging studies(e.g. CT or MRI) would have been performed to rule it out. D-dimer is usually checked if pulmonary embolism is suspected. It has a high negative predictive value for PE, so a negative D-dimer test is strong evidence that there is no PE.
