Combined positron emission tomography (PET) or single photon emission computed tomography (SPECT) with computed tomography (CT) has developed into the faste- growing imaging modality largely because combined PET or SPECT with CT data acquisition is highly synergistic in diagnosis and therapeutic evaluation. All currently available data indicate that integrated PET or SPECT/CT is more sensitive and s- ci?c than either of its constituent imaging methods alone and probably more so than images obtained from separate systems viewed side by side. The PET or SPECT/CT provides precise localization of...
