To prospectively evaluate chemical shift magnetic resonance (MR) imaging for differentiating thymic hyperplasia from tumors of the thymus gland.The institutional review board approved this study; informed consent was obtained and patient confidentiality protected. The authors assessed 41 patients (17 male, 24 female; age range, 16-78 years) in whom lesions were seen at chest computed tomography. Patients assigned to a group (n=23) (18 with hyperplastic associated Graves disease five rebound...
Spot urine samples were collected from the inhabitants of two rural communities in northwestern Bangladesh. We compared arsenic levels ([As](u); n = 346) with those water tube wells ([As](tw); range < 1-535 microg/L; 86) on an individual basis. The small variation [As](u) within subjects and highly positive correlation [As](tw) indicate that is a useful indicator exposure. Analyses showed creatinine correction was necessary, only reflected recent exposure, there substantial interindividual...

The purpose of this study was to identify brain atrophy specific for dementia with Lewy bodies (DLB) and evaluate the discriminatory performance between DLB Alzheimer's disease (AD).We retrospectively reviewed 60 30 AD patients who had undergone 3D T1-weighted MRI. We randomly divided into two equal groups (A B). First, we obtained a target volume interest (VOI) DLB-specific using correlation analysis percentage rate significant whole white matter (WM) calculated Voxel-based Specific...
ABSTRACT Objectives Neuroimaging markers for Parkinson's disease (PD)/dementia with Lewy bodies (DLB) include dopamine transporter (DAT) scanning and metaiodobenzylguanidine (MIBG) myocardial scintigraphy. It is unknown which marker useful to identify the premotor phase PD/DLB. We reported four patients who, during a negative DAT scan period, had positive MIBG result that suggested Here we report 18 additional patients. Methods This study was prospective cohort study. The recruiting period...
A 27-year-old woman with progressive diaphyseal dysplasia (Camurati-Engelmann disease) received pamidronate and corticosteroid therapy for bone pain. During therapy, disease activity was assessed serially using scintigraphy Tc-99m HMDP. With administration, the pain became worse uptake of HMDP increased, whereas administration improved reduced uptake. In this case, produced different effects. Bone allowed an objective assessment response to these treatments, accurately reflecting clinical symptoms.
The great potential of MRI for assessing gastrointestinal abnormalities in fetuses has been described. T1-weighted images may add additional information to T2-weighted diagnosing fetal abnormalities. objective this study was assess the performance a 3D volumetric interpolated breath-hold sequence (VIBE) evaluating normal and abnormal tract.VIBE provides high-quality MR colonography evaluation tract fetuses, excellent delineation meconium.
Abstract Purpose To clarify the influences of age and gender on normal fatty replacement thymus in childhood, adolescence, early adulthood using chemical‐shift MRI. Materials Methods A total 95 subjects (52 males 43 females, mean = 15.6 years, range 7–25 years) who underwent MRI were assessed prospectively. Signal intensity loss (SIL) was determined by dividing thymus/muscle ratio opposed‐phase image that in‐phase image. We evaluated SIL for its correlation with gender, uncommon...
Magnetic resonance imaging around metal joint prostheses including multiacquisition variable-resonance image combination selective at 1.5 T (from April 2014 to August 2020) was retrospectively evaluated by 2 radiologists for detection of abnormal findings (joint effusion, capsular thickening, pericapsular edema, soft-tissue fluid collection, bone marrow edema pattern the implant [BME pattern], lymphadenopathy, and others) overall impression PJI. Regarding presence communication or...
The aim was to determine the actual prevalence of liver disease and investigate contribution various risk factors among population in a methyl mercury polluted area.The study based cross sectional mass screening survey. A case-control designed estimate role for diseases.The confined small rural town 10 km north Minamata City.1406 persons aged 50 69 years were examined (78.3% total this age locality).Measurements made on basis haematological, physical, ultrasonographic examinations. Data...
Abstract Solitary fibrous tumors (SFTs) of the pleura are rare soft‐tissue that presumed to be mesenchymal origin. Most SFTs histologically benign, but up 20% may malignant. In addition, malignant transformation occur within benign SFTs, though it is rare. However, difficult diagnose by means conventional computed tomography and magnetic resonance imaging (MRI). this article we present first case SFT in an 81‐year‐old man which apparent diffusion coefficient (ADC) value ADC map based on...
Background Use of three-dimensional (3D) color volume-rendered (VR) images has been reported to be more time-efficient compared that cross-sectional computed tomography (CT) for the diagnosis peroneal tendon dislocation. However, diagnostic performance this technique not studied. Purpose To test accuracy 3D VR CT ankle dislocation in patients with acute calcaneal fractures. Material and Methods The study consisted 121 studies from 105 consecutive (85 men, 20 women; mean age, 42 years; age...
Obesity is a growing health concern in the Oceanic populations. To investigate genetic factors associated with adult obesity populations, association of single nucleotide polymorphisms (SNPs) beta-2 adrenergic receptor (ADRB2) gene was examined 694 adults living Tonga and Solomon Islands. A screening for variation 16 subjects detected 17 SNPs entire region ADRB2, which nine including two non-synonymous ones, rs1042713 (Arg16Gly) rs1042714 (Gln27Glu), were further genotyped all subjects. The...
Diagnosis of sporadic cerebellar ataxia is a challenge for neurologists. A wide range potential causes exist, including chronic alcohol use, multiple system atrophy type (MSA-C), and late cortical atrophy. Recently, an autosomal-dominant spinocerebellar (SCA) mutation was identified in cohort patients with non-MSA-C ataxia. The aim this study to genetically screen genes involved SCA Japanese single-hospital cohort.Over 8-year period, 140 were observed. There 109 (no family history at least...
Patients with ankylosing spondylitis (AS) are prone to spinal fracture after even minor trauma. We report a case of thoracic in patient AS who developed secondary neurological deficit due delayed diagnosis and prolonged conservative treatment. When the occurred, fractured segment showed no displacement, but epidural hematoma was present. Surgical treatment produced significant improvement, although incomplete paralysis persisted.
Purpose To evaluate the feasibility of using a deep learning (DL) model to generate fat-suppression images and detect abnormalities on knee magnetic resonance imaging (MRI) through image-subtraction method. Material methods A total 45 MRI studies in patients with disorders 12 healthy volunteers were enrolled. The DL was developed 2-dimensional convolutional neural networks for generating subtracting generated without any abnormal findings from those normal/abnormal detecting/classifying MRI....
