CLINICAL CORRELATION
This is a phrase often used in the sentence, "Clinical correlation is recommended." When this phrase is used, the radiologist wants the patient's doctor to make sure that the mammogram, ultrasound, or MRI finding matches up with the patient's overall clinical history and physical exam. Compared to the radiologist, the patient's doctor is much more familiar with the patient's overall health history. For example, the radiologist might see something that looks like an abscess. If the patient's doctor has observed signs/symptoms of infection such as fever, pain and increased white blood count, the diagnosis of abscess is highly likely to be correct. On the other hand, if the patient's doctor has a very low suspicion of infection, the diagnosis of abscess should be questioned.
