Correct!
3. Head magnetic resonance imaging (MRI)
Although head CT scans can be performed quickly, they do miss remedial brain lesions that would otherwise be detected by MRI (1). Electroencephalography (EEG) may be useful especially in the case of the recurrent seizures and is not necessarily wrong but currently the first priority is evaluating the patient for a surgically remedial lesion. There is no evidence of hypoglycemia, chest pathology, or arrthymia and these evaluations would likely not prove useful.
A head MRI was performed (Figure 1).

The brain MRI was interpreted as showing a "somewhat ill-defined nonspecific heterogeneously enhancing area at right frontal lobe measuring approximately 1.8 cm in conglomerate, with mild to moderate adjacent edema, may indicate neoplastic etiology".
