Abstract Objective: To explore the feasibility of two magnetic resonance imaging (MRI) sequences—high-resolution T2-weighted (HR T2) and Look-Locker T1 (LL T1) relaxometry—for investigation focal lung lesions (FLLs). As a secondary objective, we analyzed diagnostic accuracy these sequences. Materials Methods: This was prospective observational study involving 39 subjects with FLLs scanned in 1.5-T MRI system LL relaxometry HR T2 sequences focused on FLL region, addition to conventional...
To determine whether the radiomic features of lung lesions on computed tomography correlate with overall survival in cancer patients.This was a retrospective study involving 101 consecutive patients malignant neoplasms confirmed by biopsy or surgery. On images, were submitted to semi-automated segmentation and characterized basis 2,465 variables. The prognostic assessment based Kaplan-Meier analysis log-rank tests, according median value variables.Of evaluated, 28 died (16 dying from...
