Purpose To investigate whether quantitative parameters derived from dynamic contrast‐enhanced magnetic resonance imaging (DCE‐MRI) are correlated with angiogenesis and biologic aggressiveness of rectal cancer. Materials Methods A total 46 patients cancer underwent DCE‐MRI. Using a two‐compartmental model, (K trans , k ep v e iAUC) were calculated the whole‐transverse region interest (ROI) high K area ROI entire tumors. Histological specimens analyzed for tumor size; T/N stage; lymphatic,...
Objective The aim of this study was to evaluate the clinical feasibility fast 3-dimensional (3D) magnetic resonance cholangiopancreatography (MRCP) using compressed sensing (CS) in comparison with conventional navigator-triggered 3D-MRCP. Materials and Methods This retrospective approved by our institutional review board, requirement informed consent waived. A total 84 patients (male-to-female ratio, 41:43; mean age, 47.3 ± 18.8 years) who underwent 3D T2-weighted MRCP sampling perfection...
Purpose To investigate the usefulness of apparent diffusion coefficient (ADC) values derived from histogram analysis whole rectal cancer as a quantitative parameter to evaluate pathologic complete response (pCR) on preoperative magnetic resonance imaging (MRI). Materials and Methods We enrolled total 86 consecutive patients who had undergone surgery for after neoadjuvant chemoradiotherapy (CRT) at our institution between July 2012 November 2014. Two radiologists were blinded final...
The aims of this study were to observe the pattern transient motion after gadoxetic acid administration including incidence, onset, and duration, evaluate clinical feasibility free-breathing acid-enhanced liver magnetic resonance imaging using golden-angle radial sparse parallel (GRASP) with respiratory gating.In institutional review board-approved prospective study, 59 patients who provided informed consents analyzed. Free-breathing dynamic T1-weighted images (T1WIs) obtained GRASP at 3 T a...
The purpose of the study was to investigate clinical feasibility free-breathing dynamic T1-weighted imaging (T1WI) using Cartesian sampling, compressed sensing, and iterative reconstruction in gadoxetic acid-enhanced liver magnetic resonance (MRI).This retrospective approved by our institutional review board, requirement for informed consent waived. A total 51 patients at high risk breath-holding failure underwent T1WI a manner volumetric interpolated breath-hold (BH) examination with...
The associations between diffusion kurtosis imaging (DKI)-derived parameters and clinical prognostic factors of breast cancer have not been fully evaluated; this knowledge may implications for outcome prediction treatment strategies.To determine quantitative derived from DKI diffusion-weighted (DWI) the molecular subtypes cancer.Retrospective.A total 383 women (mean age, 53.8 years; range, 31-82 years) with who underwent preoperative MRI including DWI.A 3.0 T; using a spin-echo echo-planar...
Objectives To determine the clinical feasibility of abbreviated magnetic resonance image (MRI) using breath-hold 3-dimensional cholangiopancreatography (3D-MRCP) (aMRI-BH) for pancreatic intraductal papillary mucinous neoplasm (IPMN) surveillance. Materials and Methods In this retrospective study, 123 patients with 158 IPMNs (pathologically proven [n = 73] typical feature ≥2-year stability 85]) who underwent conventional MRI (cMRI) consisting contrast-enhanced pancreatobiliary BH-3D-MRCP...
TiO2 films generally undergo contact angle relaxation in the dark. It has been suggested that carbon contamination and loss of surface OH generated by UV may be major causes. However, mechanisms for long-lasting hydrophilicity have not fully understood. Here, we studied amorphous, mixed-phase, anatase, a new mechanism is proposed. After exposure oxygen plasma treatment, films' was observed over short-term (1 day) long-term (>30 days) scales with XPS analysis using two quantitative...
Background Metastasis and multiple myeloma are common malignant bone marrow lesions which may be difficult to distinguish because of similar imaging findings. The purpose this study was determine the value adding diffusion-weighted (DWI) standard MR differentiate from metastasis. Methods 25 patients with metastasis 18 underwent 3T DWI (b = 0, 800 s/mm2) were enrolled. They all had pathologically confirmed in a treatment naïve state. Two readers who blind final diagnosis measured average ADC...
OBJECTIVE. The purpose of this study was to investigate whether early kinetic parameters derived from ultrafast dynamic contrast-enhanced MRI (DCE-MRI) using compressed sensing are associated with prognostic factors for breast cancer. MATERIALS AND METHODS. We evaluated 201 consecutive women (mean age, 54.6 years) cancer (168 invasive, 33 ductal carcinoma in situ) who underwent both DCE-MRI (temporal resolution, 4.7 seconds; spatial 0.8 × 1.1 0.9 mm) and surgery between 2018 2019. Early...
The aim of this study was to evaluate the accuracy prostate volume estimates calculated from ellipsoid formula using anteroposterior (AP) diameter measured on axial and sagittal images obtained through ultrasonography (US) magnetic resonance imaging (MRI).This retrospective included 456 patients with transrectal US MRI two university hospitals. Two radiologists independently gland diameters MRI: AP images, transverse, longitudinal midsagittal images. estimates, volumeax volumesag, were by...
Purpose To compare the image quality of acquired diffusion-weighted imaging (DWI) and computed DWI evaluate lesion detectability likelihood malignancy in these datasets. Materials methods This prospective study was approved by our institutional review board. A total 29 women (mean age, 43.5 years) underwent between August 2018 April 2019 for 32 breast cancers 16 benign lesions. Three radiologists independently reviewed with b-values 1000 2000 s/mm 2 (A-b1000 A-b2000) a b-value (C-b2000)....
