A high-resolution CAT scan of a 62-year-old smoker has revealed several nodules on the right lung. Which of the following procedures would you suggest to assess the "malignancy" of these nodules?
a. Ultrasound tomography
b. Positron emission tomography
c. Magnetic resonance imaging
d. CAT scan angiography
ANS: B
Positron emission tomography (PET) is often very helpful in evaluating solitary pulmonary nod-ules. Nodules with greater than 1 cm diameter that are avid for the isotope used in PET (5 fluorodeoxyglucose) and therefore "light up" on the scan generally are more likely to be malig-nant than nodules without uptake.
