Whole-lesion histogram analysis metrics of the apparent diffusion coefficient as a marker of breast lesions characterization at 1.5 T.

Introduction: To retrospectively assess the role of whole-lesion apparent diffusion coefficient (ADC) in the characterization of breast tumors by comparing different histogram metrics.

Methods: 49 patients with 53 breast lesions underwent magnetic resonance imaging (MRI). ADC histogram parameters, including the mean, mode, 10th/50th/90th percentile, skewness, kurtosis, and entropy ADCs, were derived for the whole-lesion volume in each patient.

Accuracy of diffusion kurtosis imaging in characterization of breast lesions.

Objective: The aim of this study was to evaluate the accuracy of diffusion kurtosis in the characterization and differentiation of breast lesions.

Methods: 49 females with 53 breast lesions underwent breast MRI. The MRI magnetic field is 1.

Whole-lesion apparent diffusion coefficient (ADC) metrics as a marker of breast tumour characterization-comparison between ADC value and ADC entropy.

Objective: To prospectively assess the role of whole-lesion apparent diffusion coefficient (ADC) metrics in the characterization of breast tumours by comparing ADC value with ADC entropy.

Methods: 49 patients with 53 breast lesions underwent phased-array breast coil 1.5-T MRI.

CT in appendicitis.

Appendicitis is the most common abdominal emergency occurring in 7%-12% of the population. The aim of this article was to pictorially present the spectrum of appendix and acute appendicitis appearances on computed tomography (CT). The various appearances on CT of the normal appendix are shown as well as the CT criteria for the differentiation of perforated and non-perforated appendicitis.
