BACKGROUND AND PURPOSE In this study, we compare the performance of pretreatment Alberta Stroke Program Early Computed Tomographic scoring (ASPECTS) using noncontrast CT (NCCT) and MRI in a large endovascular therapy cohort. METHODS Prospectively enrolled patients underwent baseline NCCT and MRI and started endovascular therapy within 12 hours of stroke onset. Inclusion criteria for this anal...

BACKGROUND AND PURPOSE Negative findings on diffusion-weighted imaging (DWI) does not exclude the possibility of brainstem infarction, particularly in the acute stage of medullary lesion. Our aim was to investigate the false-negative rate of DWI in patients with acute lateral medullary infarction. METHODS We applied DWI to 26 patients with a clinical diagnosis of lateral medullary infarction ...

This paper focuses on the latest research of diffusion-weighted magnetic resonance imaging (DWI), and deals with economic benefits, diagnostic benefits, and prospects of DWI for lung cancer. The medical cost of a magnetic resonance imaging (MRI) is 81%-84% cheaper than that of 18-fluoro-2-deoxy-glucose positron emission tomography/computed tomography (FDG-PET/CT). DWI is reported to be useful f...

Objective: To investigate the application of background inhibition of fast systemic magnetic resonance diffusion imaging (DWI) in bone metastasis of lung cancer. Methods: Fifty healthy volunteers and 57 patients with lung cancer diagnosed by pathology were examined by WB-DWI, and reconstructed by 3D-MIP and black-and-white flip-flop. The skeletal system was divided into 8 regions, and the numbe...

AIM To investigate the correlation between signal intensity (SI) on diffusion-weighted imaging (DWI) and the levels of prostate-specific antigen (PSA) in patients with prostate cancer treated with radiation and hormonal therapy. PATIENTS AND METHODS Forty-four patients with prostate cancer treated with hormonal therapy and radiation therapy were evaluated. Areas with high SI on DWI were detec...

Purpose: The aim of this study was to compare the diagnostic performances abbreviated protocol (AP) magnetic resonance imaging (MRI), AP combined with diffusion-weighted (DWI), and full dynamic (FDP) in differentiation breast cancers from benign diseases.
 Materials Methods: total population consisted 68 patients who underwent MRI (1.5 Tesla) between January 2016 December 2021 for evaluati...

Diffusion-weighted imaging (DWI) and apparent diffusion coefficient (ADC) mapping are functional magnetic resonance imaging techniques for detecting water diffusion. DWI and the ADC map were performed for intracranial lesions in two dogs. In necrotizing leukoencephalitis, cavitated lesions contained a hypointense center with a hyperintense periphery on DWI, and hyperintense signals on the ADC m...

OBJECTIVES High-resolution prostate imaging may allow for detection of subtle changes in tumor size, decrease the reliance on biopsies, and help define tumor boundaries during ablation. This pilot clinical trial evaluates a novel high-resolution prostate MRI for detection of small, biopsy-proven prostate tumors. METHODS Our team developed a software that can be loaded on any modern MRI to gen...

PURPOSE The purpose of our study was to validate diffusion-weighted MRI (DWI) before and after superparamagnetic iron oxide (SPIO) injection for assessment of hepatic metastases. MATERIALS AND METHODS Eighty-six hepatic metastases (size range, 0.3-4.7 cm; mean, 1.5 cm) verified pathologically or by follow-up imaging studies in 22 consecutive patients (17 men and 5 women; 44-83 years; mean age...

BACKGROUND AND PURPOSE Diffusion-weighted MRI (DWI) can detect early ischemic changes and is sometimes used as a surrogate neurological end point in clinical trials. Recent experimental stroke studies have shown that with brief periods of ischemia, some DWI lesions transiently reverse, only to recur later. This study examined the histological condition of the tissue during the period of DWI rev...
