Abstract

Here, I review the efficacy of radiological methods in the diagnosis of diplopia/double vision. The simplest technique for achieving a successful diagnosis is to capture a wide field-of-view image. In order to start the process of diagnosis, it is fundamental to first study the image findings. Analysis based on the principle of MECE or mutually exclusive collectively exhaustive is performed using four methods: deductive reasoning, fractionation, longitudinal study, and priority setting. The conventional practical procedure to attain a diagnosis is as follows. First, identify the location of the lesion by imaging, which will shorten the list of differential diagnosis. Second, obtain as much information as possible on the characteristics of the lesion in order to determine the pathology. Third, look for any associated findings, such as tortuous vasculature around the brain. Fourth, refer to all the available information; for example, the main complaint, clinical history, previous history, family history, physical findings, physiological findings, laboratory data, previous images, and other modalities. Finally, if still in doubt, one should consult with colleagues and the attending physician. However, because rationality (statistical analyses, such as posterior probability or positive predictive value with positive findings), predicted utility, and emotions play a factor in a person's decision making, it seems impossible to completely avoid oversights and misdiagnosis.
