Impact of the PET/CT in the marshalling of the lung cancer

The lung cancer constitutes one of the main morbimortality causes in our environment, being indispensable to carry out a clinical staging with bigger accuracy that allows to define it extension with two objectives: 1. The surgery determination. 2. To predict the prognosis. At the present time it has been possible to combine the metabolic-functional image with the anatomical image creating the PET/CT modality (Positron Emission Tomography/ Computerized Tomography) with that which has improved substantially the accuracy and localization of the lesions with sensitivity of 81%, specificity of 94% and an accuracy diagnoses of 90%. In conclusion the PET/CT image technique has been indispensable in the oncological patient's handling especially in the patient with lung cancer changing the perspective diagnoses as well as the treatment avoiding invasive methods like the mediastinoscopy until the realization of extensive surgeries. The metabolic with the anatomical image fusion it has been able to locate with more accuracy the lesions to distance especially in mediastinum, as well as staging has been achieved accurately in a single exploration to the patient with lung cancer overcoming the rest of the non invasive diagnostic tests especially in the valuation of the metastatic at distance illness, transforming it into an exploration technique with a high effectiveness at an appropriate cost benefit.
