Recent Advances in Genetics, Diagnosis, Localization, and Treatment of Pheochromocytoma

Figure 2. Values in parentheses indicate expected numbers of patients with and without pheochromocytoma at different steps
during diagnosis, assuming a 2% incidence of the tumor in a population of 1000 patients undergoing testing for clinically
suspected pheochromocytoma (that is, 20 patients with and 980 without pheochromocytoma). CT = computed tomography; MRI = magnetic
resonance imaging. * For continuation of the algorithm, see .
