Dermatomyositis (DM) is an idiopathic inflammatory myopathy involving severe debilitation in need of diagnostics. We evaluated the proximal lower extremity musculature with diffusion tensor imaging (DTI), intravoxel incoherent motion (IVIM) and dynamic DTI in DM patients and controls and compared with standard clinical workup. Article Literature Review. Fat-Containing Lesions of the Liver: A Review of Differential Diagnoses. January 2020; Canadian Association of Radiologists Journal 71(1):084653711988569 US demonstrates a hypoechoic extratesticular mass. T1 and T2 weighted MR images typically show an enlarged heterogeneous mass that contains intravoxel fat in the upper scrotum or penoscrotal junction. Heterogeneous enhancement is seen at contrast-enhanced imaging.

The signals obtained in fat-suppressed T2-weighted and short tau inversion recovery (STIR) MRI images enable the use of MRI not only to establish the diagnosis of JDM but also as most powerful tool to determine the muscle involvement and to monitor disease activity and/or progression of disease.

The influence of breast density on ADC measures was also evaluated. The presence of intralesional fat provides an invaluable tool for narrowing the differential diagnosis for both benign and malignant neoplasms of the abdomen and pelvis. The ability to characterize intralesional fat is further expanded by the ability of magnetic resonance imaging to detect small quantities (intravoxel) of fat.

1 Intravoxel fat can be further subdivided into lesions in which mature adipocytes coexist Search articles and journals on SAGE Journals. Skip to main content. MENU Aim: To evaluate the correlation between intravoxel incoherent motion (IVIM) diffusion-weighted imaging (DWI) parameters and the degree of hepatic steatosis and fibrosis in children. Methods: This retrospective study was approved by the institutional review board. Intralesional fat can be divided into macroscopic or “bulk” fat versus intravoxel fat, where lipid and other soft tissue content coexist within an image voxel.

Calcifications are seen in approximately 24% of cases. 2011-12-01 Search articles and journals on SAGE Journals. Skip to main content. MENU However, in the breast intravoxel partial-volume averaging of fat and tissue may cause errors in breast ADC measurements due to the low ADC values of unsuppressed fat [9].

2020-09-02 · To evaluate the diagnostic performance of intravoxel incoherent motion (IVIM) diffusion-weighted imaging (DWI) for grading hepatic inflammation. In this retrospective cross-sectional dual-center study, 91 patients with chronic liver disease were recruited between September 2014 and September 2018.

In this study, we assessed the influence of intravoxel fat signal on breast diffusion measures by comparing ADC values obtained using a diffusion-weighted single shot fast spin-echo sequence with and without fat suppression. The influence of breast density on ADC measures was also evaluated.
