Native cardiac magnetic resonance T1 mapping and cardiac mechanics as assessed by speckle tracking echocardiography in patients with beta-thalassaemia major.

Background: We hypothesize that cardiac magnetic resonance (CMR) native T1 is associated with myocardial deformation in thalassaemia patients. The present study aimed to compare CMR native T1 values to conventional T2* values in patients with beta-thalassaemia and to explore relationships between these CMR parameters of myocardial iron overload and left ventricular (LV) and left atrial (LA) myocardial deformation.

Methods: Thirty-four (16 males) patients aged 35.

Left and Right Atrial Function and Remodeling in Beta-Thalassaemia Major.

This study aimed to assess left (LA) and right atrial (RA) function in patients with beta-thalassaemia major. Thirty-eight patients (19 males) aged 34.5 ± 10.

Primary Central Nervous System Natural Killer Cell Lymphoma in a Chinese Woman with Atypical (11)C-Choline Positron Emission Tomography and Magnetic Resonance Spectrometry Findings.

Background: Primary central nervous system (CNS) natural killer (NK)-cell lymphoma is rare with only 7 cases reported previously. Magnetic resonance spectroscopy (MRS) and [(18)F]fluorodeoxyglucose (FDG) positron emission tomography (PET) are frequently used for disease diagnosis and monitoring. Choline (CHO) PET is gaining popularity for identifying CNS lesions because of its high disease to background radioactivity ratio compared with FDG.

A review of the roles of allergic rhinitis in childhood obstructive sleep apnea syndrome.

The aim of this study was to review the literature to evaluate the association between allergic rhinitis (AR) and obstructive sleep apnea syndrome (OSAS) in childhood. A PubMed literature search (January 1970 to February 2005) was conducted using the following key words: obstructive sleep apnea, allergic rhinitis, and mouth breathing. The retrieved articles were reviewed and the levels of evidence were assessed.
