How often have you seen a doctor for a medical issue, and they ordered a diagnostic imaging test, but you weren’t exactly sure what the test involved or why it was ordered? I came across this quick guide of diagnostic tests the other day and thought it was worth sharing. Included are 12 essential medical imaging and diagnostic tests that will help you understand the type of test ordered, the purpose and strength, and the clinical applications for each diagnostic method. As a consumer and educated patient, you must have a good understanding of the modern diagnostic tools available to you and your family so you can make better healthcare decisions and, hopefully, improve patient outcomes.
