Neuromyelitis optica (NMO) has been traditionally described as the association of recurrent or bilateral optic neuritis and longitudinally extensive transverse myelitis (LETM). Identification of aquaporin-4 antibody (AQP4-IgG) has deeply changed the concept of NMO. A spectrum of NMO disorders (NMOSD) has been formulated comprising conditions which include both AQP4-IgG seropositivity and one of...

For the woman with a newly diagnosed early stage breast cancer, the routine use of pre-operative breast MRI (magnetic resonance imaging) is not indicated beyond conventional breast imaging (i.e., mammography with correlation ultrasound as indicated). There is no consistent evidence that a pre-operative breast MRI confers a benefit to the patient by improving clinical outcomes or surgical proced...

Magnetic resonance imaging (MRI) is a safe and accurate radiologic tool [1]. However, there is also a risk of physical injury or thermal injury [1,2]. During MRI scanning, wearing monitoring equipment containing metal such as pulse oximetry and ECG monitoring leads can cause contact burns; a few cases of thermal injury during MRI scanning in unconscious patients have been reported [1,2]. Howeve...

The objective of this study is to assess the criteria for metastatic involvement LN (MLN) according magnetic resonance imaging (MRI) and identify most prognostically significant. MRI data 159 removed were compared with results a morphological resected preparations. ROC- analysis (Receiver Operating Characteristic curve) was used determine diagnostic performance threshold values. test evaluated ...
