Accuracies of Chemical Shift In/Opposed Phase and Chemical Shift Encoded Magnetic Resonance Imaging to Detect Intratumoral Fat in Hepatocellular Carcinoma.

Background: Magnetic Resonance Imaging (MRI) being a noninvasive modality may help in preoperative evaluation of intratumoral fat in hepatocellular carcinoma (HCC) using chemical shift encoded (CSE) MRI and in-/opposed-phase (IOP) imaging sequences.

Purpose: To compare the diagnostic accuracy of chemical shift encoded fat fraction at three different flip angles (FAs) using quantitative chemical shift encoded MRI (CSE-MRI) with in-/opposed phase (IOP) imaging to evaluate intratumoral fat in HCC.

Study Type: Retrospective.

Postinfectious inflammatory response syndrome in HIV-uninfected and nontransplant men after cryptococcal meningitis.

The aim of our study was to describe the characteristics of postinfectious inflammatory response syndrome (PIIRS) in HIV-uninfected and nontransplant men after cryptococcal meningitis (CM).  A case-control study was designed to compare HIV-uninfected and nontransplant male CM patients with and without PIIRS. CM-PIIRS patients had increased rates of hearing loss, V-P shunt placement, amphotericin B treatment, higher cerebrospinal fluid pressures and counts in the first CM episode.
