A eficácia da técnica PET/CT na determinação precoce do câncer: uma revisão integrativa da literatura

Abstract

PET/CT or PET/SCAN corresponds to a diagnostic imaging exam that combines the resources of Nuclear Medicine with those of Radiology. The aim of this work was to analyze the effectiveness of the PET/CT exam in the investigation of early-stages cancers, through an integrative literature review. The bibliographic survey was carried out in the following databases: SciELO, PubMed Central, Academic Google, NCBI, using the descriptors: Positron Emission Tomography; X-ray Computed Tomography; Staging of neoplasms; PET/CT; Metastases, in addition to descriptors in the English language. Research has confirmed the effectiveness of the PET/CT examination when it comes to better accuracy in locating tumors, even in early stages, helping in the concomitant treatment of chemotherapy, radiotherapy, or patients who are suspected of developing thedisease, in addition to metastases initials. Studies have the perception of showing the different behaviors presented by the PET/CT technique in the detection of some cancers because before using the procedure it is necessary to recognize the types of reagents that will act so that there is effectiveness in the diagnostic accuracy.
