Background: To assess MRI in diagnosing endometriotic lesions, emphasizing T2*weighted imaging efficacy. Materials and Methods: This prospective study of 48 females (22-38 years, average 29.6) clinically suspected of endometriosis from September 2009 to April 2012. MRI was performed with a 1.5 T imager (Siemens) with a body array coil. T1, T2 and T2* weighted (2D-FLASH) sequences were obtained ...
Objective(s): The study objective was to assess the diagnostic performance of positron emission tomography (PET) for gliomas using the novel tracer 18F-fluciclovine (anti-[18F]FACBC) and to evaluate the safety of this tracer in patients with clinically suspected gliomas.Methods: Anti-[18F]FACBC was administered to 40 patients with clinically suspected high- or low-grade gliomas, followed by PET...
Diffusion is the thermally induced motion of water molecules in biological tissues, called Brownian motion. Diffusion-weighted MRI (DWI) by means of apparent diffusion coefficient (ADC) calculation can be used for in vivo quantification of the combined effects of capillary perfusion and diffusion. With the advent of echoplanar imaging (EPI), DWI of the abdomen has become possible with fast imag...
Background: Multiple sclerosis (MS) is a chronic disease that begins most commonly in young adults and is characterized pathologically by multiple areas of central nervous system (CNS) white matter inflammation, demyelination, and glial scarring. The most valuable aid for diagnosis is magnetic resonance imaging (MRI). New type of MRI has been developed on the basis of molecular diffusion which ...
Magnetic resonance imaging (MRI) is often divided into structural MRI and functional MRI (fMRI). The former is a widely used imaging technique in research as well as in clinical practice. This review describes the more important developments in structural MRI in recent years, including high resolution imaging, T2 relaxation measurement, T2*-weighted imaging, T1 relaxation measurement, magnetisa...
Accurate local staging of prostate cancer is essential for patient management decisions. Conventional and evolving magnetic resonance imaging (MRI) techniques, such as diffusion- weighted imaging, dynamic contrast-enhanced MRI, and MR spectroscopy, are promising techniques in prostate cancer imaging. In this article, we will review the current applications of conventional and ...

OBJECTIVE To describe the spectrum of magnetic resonance imaging (MRI) findings in patients with neurological manifestations of dengue. MATERIALS AND METHODS We included nine patients with dengue fever (three females and six males; age range, 9-30 years), all of whom presented with neurological manifestations. The MRI examinations, performed in 1.5 T or 3 T scanners, included T1-weighted, T2-...
A total of two postpartum women with no noteworthy medical history presented with persistent headache. Brain magnetic resonance imaging (MRI) of both revealed extensive cerebral venous thrombosis, concurrently with abnormal signals of the splenium of the corpus callosum (SCC): The splenium appeared hyperintense on T2-weighted sequences, fluid-attenuated inversion recovery (FLAIR), and diffusion...
