OBJECTIVES This study aimed to investigate the magnetic resonance imaging (MRI) characteristics and clinical and MRI follow-up findings of patients with neurological complications of enterovirus 71-related hand, foot and mouth disease. METHODS Data were collected from 12 patients who developed neurological complications of enterovirus 71-related hand, foot, and mouth disease during an enterov...

BACKGROUND As model system, a solid-tumor patient-derived xenograft (PDX) model characterized by high peptide receptor expression and histological tissue homogeneity was used to study radiopeptide targeting. In this solid-tumor model, high tumor uptake of targeting peptides was expected. However, in vivo SPECT images showed substantial heterogeneous radioactivity accumulation despite homogenous...

• Clinical use of a 1.2 Tesla open system for MRI-guided intervention is awaited. Needle artifact characteristics using MRI are clarified phantom study. Accuracy needle insertion acceptable clinical use. To evaluate the artifacts and accuracy magnetic resonance imaging (MRI) in phantom. First, apparent width on tip position error 16- 18-gauge MRI-compatible introducer needles 17-gauge cryoneedl...

BACKGROUND Bone stress injuries are common in athletes and military recruits. Only a minority of bone stress changes are available on plain radiographs. Acute bone stress is often visible on MRI as bone marrow edema, which is also seen in many other disease processes such as malignancies, inflammatory conditions and infections. The purpose of this study was to investigate the ability of radiogr...

BACKGROUND Magnetic Resonance Imaging (MRI) is a crucial medical imaging technology for the screening and diagnosis of frequently occurring cancers. However, image quality may suffer from long acquisition times for MRIs due to patient motion, which also leads to patient discomfort. Reducing MRI acquisition times can reduce patient discomfort leading to reduced motion artifacts from the acquisit...

Brain is the most important part of the human body. It consist of different types of encephalic tissues .The boundary of each of these encephalic tissues, which makes up the brain, is highly irregular. So, traditional 3-D reconstruction algorithms, using brain MRI images do not give accurate reconstruction. Two class Support vector machines are found to be very successful for pattern recognitio...

Magnetic resonance imaging, or MRI, is a way of obtaining very detailed images of organs and tissues throughout the body without the need for x-rays or "ionizing" radiation. Instead, MRI uses a powerful magnetic field, radio waves, rapidly changing magnetic fields, and a computer to create images that show whether or not there is an injury, disease process, or abnormal condition present. A new ...

Introduction The diagnosis and separation of cancerous tumors in medical images require accuracy, experience, and time, and it has always posed itself as a major challenge to the radiologists and physicians. Materials and Methods We Received 290 medical images composed of 120 mammographic images, LJPEG format, scanned in gray-scale with 50 microns size, 110 MRI images including of T1-Wighted, T...

PURPOSE To determine whether emergency subtraction dynamic contrast-enhanced MR imaging (DCE-MRI) in combination with T2- and T2*-weighted imaging of the testis is useful in the evaluation of patients with testicular torsion. MATERIALS AND METHODS Fourteen patients with surgically proven testicular torsion were examined using preoperative emergency MRI, including T2-weighted, T2*-weighted, an...

Both CT and MRI are widely known to be important tools in diagnosing spinal disorders. However, even when three-dimensional data are collected, images are often presented in two dimensions and in monochrome. Furthermore, CT and MRI represent different types of information, and it is very difficult for doctors to mentally fuse these images. We have been working to overcome these challenges, and ...
