Evaluation of non-monoexponential diffusion models for hepatocellular carcinoma using b values up to 2000 s/mm2 : A short-term repeatability study.
Non-monoexponential diffusion models are being used increasingly for the characterization and curative effect evaluation of hepatocellular carcinoma (HCC). But the fitting quality of the models and the repeatability of their parameters have not been assessed for HCC. ⋯ 2 Technical Efficacy: Stage 2 J. Magn. Reson. Imaging 2019;50:297-304.

Accuracy and precision of proton density fat fraction measurement across field strengths and scan intervals: A phantom and human study.
Complex-based chemical shift imaging-based magnetic resonance imaging (CSE-MRI) is emerging as a preferred method for noninvasively quantifying proton density fat fraction (PDFF), a promising quantitative imaging biomarker (QIB) for longitudinal hepatic steatosis measurement. ⋯ 3 Technical Efficacy: Stage 2 J. Magn. Reson. Imaging 2019;50:305-314.

Intraductal carcinoma of the prostate (IDC-P) lowers apparent diffusion coefficient (ADC) values among intermediate risk prostate cancers.
Prostatic intraductal carcinoma (IDC-P) is an aggressive variant of prostate cancer (PCa) characterized by proliferation of malignant cells within prostatic ducts/acini and nucleomegaly. ⋯ 3 Technical Efficacy Stage: 2 J. Magn. Reson. Imaging 2019;50:279-287.

Mass-forming intrahepatic cholangiocarcinoma: Can diffusion-weighted imaging predict microvascular invasion?
Microvascular invasion (MVI) is a risk factor influencing the survival rate of patients with mass-forming intrahepatic cholangiocarcinoma (IMCC). ⋯ 1 Technical Efficacy: Stage 2 J. Magn. Reson. Imaging 2019;50:315-324.

Three-dimensional ultrashort echo time (3D UTE) MRI of Achilles tendon at 4.7T MRI with comparison to conventional sequences in an experimental murine model of spondyloarthropathy.
Due to the very short T2 of its components, the normal anatomy of Achilles enthesis is impossible to define with "conventional" long echo time (TE) T2 sequences. However, this is a common site affected by rheumatologic disease. Early abnormalities related to inflammatory processes are impossible to detect in this location. ⋯ 2 Technical Efficacy: Stage 2 J. Magn. Reson. Imaging 2019;50:127-135.
