Magnetic resonance imaging for the study of mediastinal adenopathies in lung cancer: Comparison with standard tests.

Background: Lung cancer is the second most common cancer in both men and women. Mediastinal lymph node involvement in these patients, determined by imaging tests, indicates prognosis and modifies therapeutic attitude.

Purpose: The aim of this study was to analyze the diagnostic capacity of magnetic resonance imaging (MRI) in the study of the mediastinum in comparison with conventional tests (computed tomography [CT] and positron-emission tomography [PET] or PET/CT scans), taking histology as the gold standard.

Usefulness of Positron Emission Tomography in the Examination of Hilar and Mediastinal Lymphadenopathies in Patients with Suspicion of Lung Cancer.

Introduction: Lung cancer is a major health problem. Mediastinal staging performed with the aid of imaging techniques is essential for appropriate disease treatment and prognosis. Accordingly, this study aimed to ascertain the usefulness of positron emission tomography (PET) in mediastinal staging, establish the best maximum standardized uptake value (SUV) cutoff point, compare its usefulness to that of computed tomography (CT), and determine the influence of histological tumour subtype.

Use of Magnetic Resonance Imaging for N-Staging in Patients with Non-Small Cell Lung Cancer. A Systematic Review.

Introduction: The aim of this study is to assess the diagnostic value of the magnetic resonance imaging (MRI) in differentiating metastasic from non-metastatic lymph nodes in NSCLC patients compared with computed tomography (CT) and fluorodeoxyglucose (FDG) - positron emission tomography (PET) or both combined.

Methods: Twenty-three studies (19 studies and 4 meta-analysis) with sample size ranging between 22 and 250 patients were included in this analysis. MRI, regardless of the sequence obtained, where used for the evaluation of N-staging of NSCLC.
