MRI-Based Radiomic Signature Identifying Secondary Loss of Response to Infliximab in Crohn's Disease.

Up to 50% of patients with Crohn's disease (CD) experience secondary loss of response (SLR) to infliximab. Patients with SLR may show clinical signs of iron deficiency as a result of inflammation despite being iron-replete. The magnetic resonance imaging (MRI)-based radiomic index, R2, can detect changes in iron metabolism.

Dual Energy Spectral CT Imaging in the assessment of Gastric Cancer and cell proliferation: A Preliminary Study.

Gastric cancer is one of the main diseases leading to cancer-related death. The recently introduced dual-energy spectral CT (DEsCT), allows to obtain many quantitative measurements from iodine-based material decomposition (MD) images, which contribute to improve the accuracy of staging of GC comparing to multidetector spiral CT. And Ki-67 is a well-recognized nuclear antigen-specific biomarker reflecting cellular proliferation for estimating growth fractions of various tumor types.

Morphometric Study of Endoscopic Transoccipital Approach to Lateral Ventricle With Magnetic Resonance Imaging.

Endoscopic surgery has been applied in the treatment of lateral cerebral ventricular lesions for years, but few morphometric studies in vivo have been reported with medical imaging. In the current study, the authors aimed to investigate the related morphometric data of endoscopic transoccipital approach to lateral ventricle with the magnetic resonance images of lateral ventricle from healthy adults anonymously. Seven parameters on the axial plane and 3 on the left occipital horn of sagittal plane of T1-weighted image were measured and the results were as follows: The distance from incision to the cranium posterior intersection with midsagittal line (D1) was 29.
