The purpose of our study was to investigate the value of diffusion-weighted magnetic resonance imaging (DW-MRI) to discriminate benign and malignant focal lesions of the liver using parallel imaging technique. A total of 77 patients and 65 healthy controls were enrolled in the study. DW-MRI was performed with b-factors of 0, 500 and 1000 s/mm(2), and the(More)
To evaluate the usefulness of diffusion- weighted MRI (DWI) in the detection and staging of liver fibrosis and inflammation. DWI was performed with b-factors of 0, 500 and 1000 s/mm². ADC values were obtained by placing circular regions of interest in four segments of the liver. Differences between the study (n = 34) and control groups’ (n = 25) ADC values(More)
BACKGROUND Magnetic resonance (MR) imaging has been established as the best imaging modality for the detection, localization, and staging of uterine cancers. Recently, the usefulness of diffusion-weighted imaging (DWI) in the diagnosis of cancers has been reported in several studies. PURPOSE To calculate the apparent diffusion coefficient (ADC) values of(More)
PURPOSE To detect apparent diffusion coefficient (ADC) values in normal abdominal organs using non-breath-hold high b-value diffusion-weighted magnetic resonance imaging (DW-MRI) with a parallel imaging technique. MATERIALS AND METHODS A total of 50 patients with normal abdominal MRI findings were retrospectively enrolled. DW-MRI was performed with(More)
RATIONALE AND OBJECTIVES The aim of this study was to compare four different fat-suppressed T2-weighted sequences with different techniques with regard to image quality and lesion detection in upper abdominal magnetic resonance imaging (MRI) scans. MATERIALS AND METHODS Thirty-two consecutive patients referred for upper abdominal MRI for the evaluation of(More)
PURPOSE We investigated the relationship between the apparent diffusion coefficient (ADC) values of the colonic wall and the pathologic pericolonic lymph nodes (PCLNs) and inflammatory activity in ulcerative colitis patients by diffusion-weighted magnetic resonance imaging (DW-MRI). MATERIALS AND METHODS A total of 28 ulcerative colitis patients (9(More)
PURPOSE The purpose of this study was to evaluate the feasibility of diffusion-weighted imaging in the diagnosis of the urinary bladder and prostate carcinomas. The apparent diffusion coefficient (ADC) values of the malignant and normal tissues were correlated. MATERIALS AND METHODS A total of 23 patients with 14 urinary bladder carcinomas and 9 prostate(More)
To evaluate the value of diffusion-weighted MRI (DWI) in the diagnosis of acute appendicitis. 119 patients with acute appendicitis and 50 controls were enrolled in this prospective study. DWI was obtained with b factors 0, 500 and 1000 s/mm² and were assessed with a visual scoring system by two radiologists followed by quantitative evaluation of the DW(More)
PURPOSE The purpose of this study was to assess the diagnostic value of unenhanced magnetic resonance imaging (MRI) in the diagnosis of acute appendicitis and compare with Alvarado scores and histopathological results. MATERIALS AND METHODS The study included 85 consecutive patients (mean age, 26.5±11.3 years) who were clinically suspected of having acute(More)
PURPOSE Our purpose was to determine whether quantitative diffusion-weighted MR imaging (DWI) could be used in discrimination of benign and malignant primary solid and cystic renal tumors. MATERIALS AND METHODS A total of 105 consecutive patients with renal masses and 30 healthy controls were enrolled in this prospective study. Dynamic contrast enhanced(More)
