Table 1. Sensitivity of NCE-MR, CE-MR, and CT; Individual Interpretations.
This table illustrates the sensitivities of each modality for each of the 15 diagnoses in our cohort. The proportion that answered yes to the question, “did the post-contrast images help or add to the diagnosis in any way?,” are presented along with the response rate. Total cases sum to 116 as three patients each had two independent diagnoses.
