For the diagnostic imaging of lung cancer, chest X-rays and chest CT were used historically. Recently, high-resolution Multi Detector-row CT (MDCT) including helical CT that can be rebuilt in Multi Planar Reconstoruction (MPR) has become useful for diagnosis. PET or PET /CT has also been used for the determination of lung cancer disease stage. However, the imaging abilities of both CT and PET have their limitations. Therefore, we examined the recent diagnostic imaging and treatment results in lung cancer cases that exhibited negative PET findings. As a result, follow-up of lung tumor patients must focus on false-negative PET/CT findings. Depending on each case, we must conduct radical operation within an appropriate timeframe after thoracoscopic lung biopsy.
