Preoperative staging of rectal cancer using magnetic resonance imaging: comparison with pathological staging.

Background: The aim of this study was to evaluate the accuracy of magnetic resonance (MR) in loco-regional staging of rectal cancer by comparing the MR results with histologic findings, considered as standard reference.

Methods: Between July 2013 and March 2015, fifty-two patients, 27 (51.9%) males, age 66.

Clinical and magnetic resonance evolution of "infarct-like" myocarditis.

Aims: To analyse the clinical and magnetic resonance evolution of myocarditis in patients with an "infarct-like" presentation pattern.

Methods: The study is a retrospective analysis of 52 patients with clinical diagnosis of "infarct-like" myocarditis confirmed by CMR as acute myocarditis according to Lake Louise criteria and 6 months follow-up. The CMR protocol included T2-weighted (oedema), early (hyperaemia) and late (fibrosis/necrosis) gadolinium enhancement sequences, according to Lake Louise criteria.
