Preoperative prediction of lymphovascular invasion in invasive breast cancer with dynamic contrast-enhanced-MRI-based radiomics.
Lymphovascular invasion (LVI) status facilitates the selection of optimal therapeutic strategy for breast cancer patients, but in clinical practice LVI status is determined in pathological specimens after resection. ⋯ 1 Technical Efficacy Stage: 2 J. Magn. Reson. Imaging 2019;50:847-857.

Observational StudyIntravoxel Incoherent Motion Combined With Dynamic Contrast-Enhanced Perfusion MRI of Early Cervical Carcinoma: Correlations Between Multimodal Parameters and HIF-1α Expression.
The identification of hypoxia inducible factor (HIF-1α) expression is helpful for the quantitative assessment of tumor hypoxia. The application of multimodal imaging techniques may play a part in the assessment of HIF-1α expression of cervical carcinoma. ⋯ 1 Technical Efficacy Stage: 2 J. Magn. Reson. Imaging 2019;50:918-929.

Comparative Study Observational StudyComparing invasive with MRI-derived intracranial pressure measurements in healthy elderly and brain trauma cases: A pilot study.
Intracranial pressure (ICP) is an important physiological parameter in several neurological disorders. Considerable effort has been made to measure ICP noninvasively. MR-based ICP (MR-ICP) is a nonempirical method based on principles of cerebrospinal fluid (CSF) physiology, where ICP is obtained from measurements of blood and CSF flows to and from the cranium during the cardiac cycle. ⋯ 3 Technical Efficacy: Stage 2 J. Magn. Reson. Imaging 2019;50:975-981.

Accurate measurement of the liver iron concentration (LIC) is needed to guide iron-chelating therapy for patients with transfusional iron overload. In this work, we investigate the feasibility of automated quantitative susceptibility mapping (QSM) to measure the LIC. ⋯ 1 Technical Efficacy: Stage 2 J. Magn. Reson. Imaging 2019;50:725-732.

Diffusion kurtosis imaging-derived histogram metrics for prediction of KRAS mutation in rectal adenocarcinoma: Preliminary findings.
Although histological examination is the standard method for assessing genetic status, the development of a noninvasive method, which can display the heterogeneity of the whole tumor to supplement genotype analysis, might be important for personalized treatment strategies. ⋯ 3 Technical Efficacy: Stage 2 J. Magn. Reson. Imaging 2019;50:930-939.
