Purpose To evaluate the diagnostic value of 3D arterial spin labeling (ASL) for noninvasive quantification renal blood flow (RBF) in patients with chronic kidney disease (CKD). Materials and Methods CKD ( n = 27) healthy volunteers 36) underwent 3T ASL magnetic resonance imaging, inversion times from 1200 to 2000 msec preliminary test, 1800 formal experiments. The cortical RBFs were compared, a correlation between RBF estimated glomerular filtration rate (eGFR) was evaluated. Results For...
This study aimed to evaluate the potential of deep learning (DL)-assisted automated three-dimensional quantitative tumor burden at MRI predict postoperative early recurrence (ER) hepatocellular carcinoma (HCC).
Previous studies have reported abnormal amplitude of low-frequency fluctuation and regional homogeneity in patients with migraine without aura using resting-state functional magnetic resonance imaging. However, how whole brain connectivity pattern its corresponding changes is unknown. In the current study, we employed a recently developed (FcHo) method to identify voxel-wise patterns 21 gender age matched healthy controls. Moreover, analysis was used reveal connectivities. FcHo analyses...
A need for adequate and early exposure to radiology practice is rising in undergraduate students, taking competency development as the orientation. We aimed develop a competency-based model of practice-based learning education.The was constructed upon an e-learning smart class environment, with case-based simulators development. To assess effectiveness, randomized controlled experiment performed, where 57 third-year medical students received (Smart-Class group) another traditional teaching...
To assess kidney damage in a rat model of type-2 diabetic nephropathy based on apparent diffusion coefficient (ADC) data obtained from ultra-high b-values and discuss its relationship to the expression aquaporins (AQPs). This study was approved by institutional Animal Care Use Committee. Thirty male Sprague-Dawley rats were randomised into two groups: (1) untreated controls (2) diabetes mellitus (DM). All underwent diffusion-weighted imaging (DWI) with 18 (0–4500 s/mm2). Maps low ADC...
Background: The aim of this study was to assess the performance apparent diffusion coefficient (ADC) measurement obtained with diffusion-weighted magnetic resonance imaging (DW-MRI) distinguish renal cell carcinomas (RCCs) from small benign solid tumors (≤4 cm). Methods: In cross-sectional study, 49 consecutive patients histopathologically confirmed tumors, and seven healthy volunteers were imaged using nonenhanced MRI DW-MRI. ADC map calculated b values 0, 50, 400, 600 s/mm2 compared via...
Investigating the effect of post-labeling delay (PLD) on regional cerebral blood flow (CBF) in adults and optimizing PLD for arterial spin-labeling (ASL) magnetic resonance (MR) imaging are important.Pseudo-continuous ASL with a three PLDs protocol was performed 90 healthy adult volunteers from January 2018 to February 2019. Healthy subjects were divided into youth group (mean age, 30.63 years; age range, 20-44 years), middle-aged 52.16 range 45-59 years) elderly 66.07 60-77 years). After...
Abstract Rational: Spontaneous adrenal hematoma in pregnancy is a very rare condition. Herein we present an additional case of unilateral spontaneous pregnant woman, aiming to share this experience and summarize the signal characteristics simple magnetic resonance imaging (MRI). Patient concerns: A 28-year old woman was referred our hospital with vague paroxysmal left-side back pain at 17 weeks gestation. Diagnosis: MR scan abdomen revealed 8.1 × 7.7 6.8 cm round mass left region, which...
To investigate the age-dependent changes in regional cerebral blood flow (CBF) healthy adults by fitting mathematical models to imaging data.In this prospective study, 90 underwent pseudo-continuous arterial spin labeling of brain. Regional CBF values were extracted from images each subject. Multivariable regression with Akaike information criterion, link test, and F test (Ramsey's equation specification error test) was performed for 7 every brain region determine best model relationship...
The objective of our study was to prospectively evaluate renal diffusion as shown by diffusion-weighted imaging (DWI) and its relationship with the residual function (RRF) in continuous ambulatory peritoneal dialysis (CAPD) patients.Forty CAPD patients 40 healthy volunteers were recruited, all underwent conventional fat-saturated echo-planar DWI three b values (0, 300, 600 s/mm(2)). parenchymal thickness apparent coefficients (ADCs) measured, both compared between two groups. relationships...
Background: Whether the effect of post-labeling delay (PLD) on cerebral blood flow (CBF) is influenced by age and sex in adults unknown. In this study, we mainly aimed to explore potential influence PLD CBF. Methods: This prospective study enrolled 90 healthy adult volunteers (49.47±15.63 years age; range, 20–77 years; 47 female; 43 male). All participants underwent 3-dimensional (3D) pseudo-continuous arterial spin labeling (ASL) imaging with 3 different PLDs (1,525, 2,025, 2,525 ms). The...
To the editor: Abdominal hernias are relatively common in patients on continuous ambulatory peritoneal dialysis (CAPD), with a prevalence of 4%-14%.1,2 Failure to detect an occult contralateral hernia (OCH) may lead requirement second surgery repair and severe complications, such as inadequacy strangulation herniated loop intestine. Here we report case CAPD whose bilateral inguinal was missed by routine examinations, but later correctly diagnosed CT peritoneography (CTP). A 53-year-old man...
