Background To compare stretched‐exponential and monoexponential model diffusion‐weighted imaging (DWI) in prostate cancer normal tissues. Methods Twenty‐seven patients with underwent DWI exam using b‐values of 0, 500, 1000, 2000 s/mm 2 . The distributed diffusion coefficients (DDC) α values tissues were obtained apparent coefficient (ADC) model. ADC, DDC (both 10 −3 mm /s), (range, 0–1) compared among different ADC also correlated each tissue, the standardized differences between Results...
Gliomas grading is important for treatment plan; we aimed to investigate the application of intravoxel incoherent motion (IVIM) diffusion-weighted imaging (DWI) in gliomas grading, by comparing with three-dimensional pseudocontinuous arterial spin labeling (3D pCASL). 24 patients (13 high grade and 11 low gliomas) underwent IVIM DWI 3D pCASL before operation; maps fast diffusion coefficient (<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"...
To assess the influence of region interest (ROI) on tumor apparent diffusion coefficient (ADC) measurements and interobserver variability in pancreatic ductal adenocarcinoma (PDAC).Twenty-two patients recruited with pathology-proven PDAC underwent diffusion-weighted imaging (DWI, 3.0T) prior to surgical resection. Two independent readers measured ADCs according three ROI methods: whole-volume, single-slice, small solid sample tumor. Minimum mean were obtained. The for each methods was...
To evaluate the performance of multiparametric neurite orientation dispersion and density imaging (NODDI) radiomics in distinguishing between glioblastoma (Gb) solitary brain metastasis (SBM).
Aims To determine whether peripheral retinal irradiation with low-energy red light can effectively and safely delay the progression of myopia. Methods The guinea pigs (age, 2 weeks) were used. central or retina was exposed to for 3 min each at 9:00 AM 5:00 PM daily. At day 28, examinations performed assess condition axial length, cornea lens, choroid thickness. ratio length a given time baseline used growth. Results Under same energy density mode, illuminance (energy density) on layer is...
The aim of this study was to assess the diagnostic accuracy diffusion kurtosis magnetic resonance imaging parameters for differentiating high-grade gliomas (HGGs) from primary central nervous system lymphomas (PCNSLs).Diffusion parameters, including fractional anisotropy (FA), mean diffusivity (MD), axial (λ// ), radial (λ⊥ ); and (MK), (K// (K⊥ were normalized contralateral normal-appearing white matter (NAWMc) decrease inter-individual inter-regional changes across entire brain, then...
Abstract Early therapeutic effects of anti-angiogenic agent ZD6474 upon nasopharyngeal carcinoma (NPC) in nude mouse were monitored by using intravoxel incoherent motion (IVIM) diffusion-weighted imaging (DWI). Mice bearing NPC underwent IVIM DWI at baseline and after 1, 3 7 days treatment with or vehicle (n = 12 per group). Parameters apparent diffusion coefficient (ADC), true (D), perfusion fraction (f) blood pseudodiffusion (D*) different time points compared between the two groups within...
Summary Objective The pathogenesis of benign adult familial myoclonic epilepsy ( BAFME ) remains unknown, although cerebellar pathologic changes and brain hyperexcitability have been reported. We used resting‐state functional magnetic resonance imaging fMRI to examine the connectivity between cerebellum cerebrum in a Chinese family with for first time. Methods Eleven adults 15 matched healthy controls underwent blood oxygen level–dependent BOLD scanning. seeds, including bilateral crus I,...
Sparse estimation techniques are widely utilized in diffusion magnetic resonance imaging (DMRI). In this paper, we present an algorithm for solving the ℓ0 sparse-group problem and apply it to tissue signal separation DMRI. Our solves directly, unlike existing approaches that often seek solve its relaxed approximations. We include mathematical proofs showing will converge a solution satisfying firstorder optimality condition within finite number of iterations. DMRI data tease apart...
To investigate the associations between diffusion parameters obtained from multiple-b-values weighted imaging (DWI) of pancreatic ductal adenocarcinoma (PDAC) and aggressiveness local stage prediction, assess values quantitative for discrimination tumors healthy pancreas.Fifty-one patients with surgical pathology-proven PDAC (size, 35 ± 12 mm) fifty-seven volunteers were enrolled. Diffusion including monoexponential apparent coefficient (ADCb ADCtotal) biexponential intravoxel incoherent...
Amide proton transfer (APT) imaging has been gradually applied to cervical cancer, yet the relationships between APT and multiple model diffusion-weighted (DWI) have be investigated. This study attempted evaluate added value of 3-dimensional (3D) DWI for assessing prognostic factors cancer.This prospective diagnostic was conducted in The First Affiliated Hospital Zhengzhou University. A total 88 consecutive patients with cancer underwent 11 b-values (0-2,000 s/mm2). apparent diffusion...
To investigate the monoexponential and biexponential apparent diffusion parameters in different anatomical regions of healthy pancreas using intravoxel incoherent motion (IVIM) weighted imaging (DWI).Fifty-seven volunteers (age, 45.0 ± 10.8 years) were recruited. DWI was performed with 9 b-values (0, 20, 50, 100, 200, 400, 600, 800, 1000 s/mm(2) , respectively). The ADC calculated for all linear regression yielding ADCtotal . ADCb value DWI, slow component (ADCslow ), microcirculation...
Background Prostate cancer and stromal hyperplasia (SH) in the transition zone (TZ) are difficult to discriminate by conventional magnetic resonance imaging (MRI) diffusion-weighted (DWI). Purpose To investigate apparent diffusion coefficient (ADC) of prostate SH TZ with histogram analysis ability ADC metrics differentiate between these two tissues. Material Methods Thirty-three 29 lesions 54 patients undergoing preoperative DWI (b-value 0, 1000 s/mm 2 ) were analyzed. All on MR images...
Purpose: To investigate changes in usage of computed tomography urography (CTU), indications for CTU, and rates positive findings over time. Methods: Retrospective review data from April 2000 to December 2005 assessed overall findings, suspected transitional cell carcinomas (TCCs), benign genitourinary (GU), significant non-GU findings. Data were analyzed based on specialty ordering physicians requisition indications. Results: One thousand two hundred seventy-one patients had 1746 CTUs,...
The present study aimed to determine if the standardized uptake value (SUV) determined with 18F‑FDG PET‑CT can be used predict radiation pneumonitis (RP) in lung cancer patients who receive radiotherapy. A total of 40 non‑small cell received examinations prior and following average SUV tissue were measured at differing doses. differences between without RP, ratio irradiated tissues compared that non‑irradiated (L/B) compared. There no mean RP groups also significant within or doses <5 Gy, 5...
