Molecular Imaging in Individualized Cancer Management

X-rays were discovered by Karl Roentgen in 1895, and with that discovery came

the ability to see structures within the living human body without having to directly

sample the tissue. Imaging, particularly cross-sectional techniques, has revolu-

tionized the practice of medicine. These techniques employ ionizing radiation, such

as computed tomography (CT) scanning, single-photon emission computed

tomography (SPECT), and positron emission tomography (PET), as well as non-

ionizing energy, such as ultrasound and magnetic resonance imaging (MRI). Some

of the most exciting and practical major advances are unfolding within theMRI and

PET technologies, specifically with regard to molecular imaging.
