Purpose: The aim of this study was to compare the tumor conspicuity on actual measured diffusion-weighted images (aDWIs) and computed DWI (cDWI) of human breast tumors and to examine, by use of a phantom, whether cDWI improves their conspicuity. Materials and Methods: We acquired DWIs (b-value 0, 700, 1400, 2100, 2800, and 3500 s/mm2) of 148 women with breast tumors. cDWIs with b-values of 1400, 2100, 2800, and 3500 s/mm2 were calculated from aDWI scans where b = 0 and 700 s/mm2; the tumor…

Diagnostic value of diffusion-weighted imaging with synthetic b-values in breast tumors: comparison with dynamic contrast-enhanced and multiparametric MRI

The addition of synthetic b-values to acquired DWI afforded a better lesion conspicuity without increasing acquisition time and was particularly useful in dense breasts, however, its supportive role for DWI breast cancer detection is still not definite.

Image quality and diagnostic value of diffusion-weighted breast magnetic resonance imaging: Comparison of acquired and computed images

A-b1000 DWI is suitable for breast lesion evaluations, considering its better image quality and comparable diagnostic values compared to that of A-b 2000 and C-b2000 images.

High-Resolution, High b-Value Computed Diffusion-Weighted Imaging Improves Detection of Pancreatic Ductal Adenocarcinoma

It is found that the r-cDWI1000 outperformed both conventional computed DWI and acquired high-resolution DWI in the visualization of PDAC and enabled significant improvement in lesion detection and a higher incidence of a high lesion-to-pancreas intensity relation.

Optimal target b-value on computed diffusion-weighted magnetic resonance imaging for visualization of pancreatic ductal adenocarcinoma and focal autoimmune pancreatitis

Purpose To compare computed diffusion-weighted imaging (cDWI) feasibility with that of directly acquired DWI for visualizing pancreatic ductal adenocarcinoma (PDAC) and focal autoimmune pancreatitis

Comparative Study of Diffusion-Weighted Imaging Versus Dynamic Contrast Enhanced-MRI in Diagnosis of Breast Tumors

It is found that benign or malignant breast lesions can be identified and characterized with high sensitive multi-parametric MRI of breast, which was more significant than DCE-MRI and DWI alone and the breast MRI had higher sensitivity and specificity in distinguishing malign breast lesions from benign lesions.

Utility of magnetic resonance imaging for differentiating malignant mesenchymal tumors of the uterus from T2-weighted hyperintense leiomyomas

The T1 bright area on qualitative assessment and mean apparent diffusion coefficient value on quantitative assessment yielded the most independent magnetic resonance imaging differentiators of malignant mesenchymal tumors of the uterus and T2-weighted hyperintense leiomyoma.

Computed DWI with the b-values of 1300 and 1600 would be suitable for the evaluation of cervical cancer due to good tumor conspicuity and total image quality.

Investigation of the optimal b-value to detect breast tumors with diffusion weighted imaging by 1.5-T MRI

DWI with a b-value of approximately 1400-1500 s/mm2 is recommended for optimizing breast tumor detectability.

Diffusion-weighted MR for differentiation of breast lesions at 3.0 T: how does selection of diffusion protocols affect diagnosis?

Optimum ADC determination and DW imaging quality at 3.0 T was found with a combined b value protocol of 50 and 850 sec/mm(2), which provided a high accuracy for differentiation of benign and malignant breast tumors.

Computed diffusion-weighted MR imaging may improve tumor detection.

Computed DW MR imaging in the body allows higher-b-value images to be obtained with a good SNR and may improve disease detection, and the feasibility of the technique to improve lesion detection in oncologic cases is investigated.

Diffusion-weighted imaging (b value = 1500 s/mm2) is useful to decrease false-positive breast cancer cases due to fibrocystic changes

Adding ADC values calculated from DWI to BI-RADS is a useful way to improve differential diagnostic accuracy for malignant tumors and benign lesions, especially for DCIS versus fibrocystic changes, except in cases of ductal hyperplasia.

The results indicated that when only one b value is used, the b value in which signal intensities of normal mammary gland decreases down to noise level, and the contrast between normal mammaries gland and tumor tissues is recommended.

It is concluded that DWI has a potential for clinical appreciation in detecting breast cancer and that the distribution of low ADC values and pathologic cancer extension shows precise distribution as cancer extension.
