Chronic kidney disease (CKD) remains a major public health concern, requiring better predictive models for early intervention. This study evaluates deep learning model (DLM) that utilizes raw chest X-ray (CXR) data to predict moderate severe function decline. We analyzed from 79,219 patients with an estimated Glomerular Filtration Rate (eGFR) between 65 and 120, segmented into development (n = 37,983), tuning 15,346), internal validation 14,113), external 11,777) sets. Our DLM, pretrained on...
To evaluate the locations and associated erosions of tophaceous gout in knee to reevaluate its characteristic magnetic resonance imaging features.We performed a retrospective review (MR) images knees 30 patients with histopathologically confirmed gouty tophi. Each lesion was evaluated for location, morphology, signal intensity, bone erosion or intraosseous involvement.The masses were commonly located on medial aspect infrapatellar fat pad anterior joint recess (n = 28, 87%), space adjacent...
Polyacrylamide hydrogel (PAAG) was widely used for injection augmentation mammoplasty in Eastern Europe and China although uncommon the western countries. However, safety of this procedure remained controversial. Herein, we report a 30-year-old woman with history by PAAG developed galactoceles during her pregnancy. Ultrasound magnetic resonance imaging showed huge cystic lesions bilateral breasts; as result, normal breast tissue almost completely replaced. On basis findings, patient...
Background: Redundancy of the capsule has been considered to be main pathologic condition responsible for atraumatic posteroinferior multidirectional shoulder instability; however, there is a paucity measurements providing quantitative diagnosis. Purpose: To determine significance superior-capsular elongation and its relevance instability at magnetic resonance (MR) arthrography. Material Methods: MR arthrography was performed in 21 patients with without instability. One observer made...
Patients with pathological stage IA non-small cell lung cancer (NSCLC) may relapse despite complete surgical resection without lymphovascular invasion. A method of selecting a high-risk group for adjuvant therapy is necessary. The aim this study was to assess the predictive value 18F-fluorodeoxyglucose (FDG) uptake and morphologic features computed tomography (CT) recurrence in NSCLC. One hundred forty-five patients NSCLC who underwent pretreatment FDG positron emission CT evaluations were...
Purpose The magnetic resonance (MR) T2 value of cartilage is a reliable indicator tissue properties and therefore may be used as an objective diagnostic tool in early meniscal degeneration. purpose this study was to investigate age, gender, location, zonal differences MR the posterior horns knee menisci asymptomatic subjects. Methods Sixty volunteers (30 men 30 women) were enrolled divided into three different age groups: 20–34, 35–49 50–70 years. inclusion criteria BMI<30 kg/cm2, normalized...
Migraine is commonly comorbid with insomnia; both disorders are linked to functional disturbance of the default mode network (DMN). Evidence suggests that DMN could be segregated into multiple subnetworks specific roles underline different cognitive processes. However, relative contributions in comorbidity migraine and insomnia remain largely unknown. This study sought identify altered connectivity (FC) profiles insomnia. Direct group comparisons healthy controls, followed by conjunction...
Langerhans cell histiocytosis (LCH), formerly known as X, refers to a spectrum of diseases characterized by idiopathic proliferation histiocytes that produce either focal (localized LCH) or systemic manifestations (Hand-Schüller-Christian disease and Letterer-Siwe disease). Localized LCH accounts for approximately 60-70 % all cases. Osseous involvement is the most common manifestation typically involves flat bones, along with lesions skull, pelvis, ribs. in bone shows wide clinical...
Context: Breast cancer subtype (BCS) and lymphovascular invasion (LVI) have both been independently demonstrated as prognostic factors. Aims: The objective of this investigation was to evaluate the power LVI among BCSs. Settings Design: From an institutional database, 2017 women with a histopathologically confirmed diagnosis breast treated between January 2006 December 2014 were consecutively selected. Subjects Methods: Information recorded for each patient included age at diagnosis, year...
Abstract The compression of peripheral nerves by benign fatty tumors has rarely been reported in the literature. We present case a patient who had subcutaneous lipoma region knee that caused common peroneal nerve palsy and appeared to compress on sonography. surgical removal allowed complete recovery. © 2009 Wiley Periodicals, Inc.

Abstract Purpose To identify the ultrasound (US) findings of intra-epineurial corticosteroid injection during US-guided hydrodissection in patients with carpal tunnel syndrome (CTS), and to determine their clinical relevance relation treatment outcomes. Materials Methods We performed 101 hydrodissections injections CTS, evaluated pre- post-injection US findings. categorized these into two groups based on occurrence injection. also recorded data including sex, age, side injection, BMI,...
The Hoffa fat pad (infrapatellar pad) is a source of post-traumatic anterior knee pain, and disease syndrome leading to chronic inflammation the pad. Herein, change in T2* relaxation time was measured rodent cruciate ligament transection (ACLX) model order (i) examine causal relationship (ACL) deficiency (ii) demonstrate feasibility using as an imaging biomarker monitor progression. Three groups male Sprague Dawley rats (n = 6 each group), received either no intervention; sham surgery at...
Subjective cognitive decline (SCD) and migraine are often comorbid. Hippocampal structural abnormalities have been observed in individuals with both SCD migraine. Given the known functional heterogeneity along long axis (anterior to posterior) of hippocampus, we aimed identify altered patterns covariance within hippocampal subdivisions associated comorbidities.A seed-based network analysis was applied examine large-scale anatomical changes anterior posterior hippocampus SCD, healthy...
A spherical mass of the right psoas muscle was found incidentally by magnetic resonance health examination in a 43-year-old woman. The patient had complained numbness her leg over previous six months and neuralgia at time computed tomography-guided core biopsy, which done to establish diagnosis. To our knowledge, femoral nerve neuropathy caused an intramuscular schwannoma arising from has not been previously published.
This study investigated the effect of resistant maltodextrin (RMD) on reproduction in streptozotocin (STZ)–nicotinamide-induced type 2 diabetic male rats. Forty rats were induced with diabetes by a single intraperitoneal injection STZ (50 mg kg−1) and nicotinamide (100 kg−1). Five groups analysed total: normal, without RMD, RMD 1.2 g per 100 diet (1×), 2.4 (2×), 6.0 (5×). The supplement, compared to those showed improved plasma glucose control, attenuated insulin resistance recovery...
Although ultrasound (US)-guided injection techniques for magnetic resonance arthrography of the hip have been used with increasing frequency to diagnose internal joint derangements, little is known about patient tolerance, which relevant information patients. The objective this study was evaluate prospectively association between possible influencing factors and discomfort felt during performance anterior US-guided targeting femoral head-neck junction arthrography.Forty-four consecutive...
Background Corticosteroid injections are a popular technique for carpal tunnel syndrome (CTS) treatment and believed to provide rapid symptom relief. Purpose To use magnetic resonance diffusion tensor imaging (MR-DTI) determine the association between values of median nerve (MN) at several anatomic locations relief in patients with CTS following corticosteroid injection. Material Methods MR-DTI was performed on 15 wrists 12 before two weeks after ultrasound-guided injections. We recorded...
The pathogenesis of chronic kidney disease (CKD) is multifactorial. In the progression CKD arthropathy, arteriosclerosis may alter knee subchondral bone marrow by altering blood flow through vasculature. Herein, multi-parametric MRI assessment, including dynamic contrast enhanced magnetic resonance imaging (DCE-MRI), spectroscopy (MRS), T2*, MR angiography (CE-MRA), and micro-CT were applied in a rodent nephrectomy model to: 1) investigate perfusion its relationship to fat water content...
