Intravoxel incoherent motion (IVIM) diffusion-weighted imaging (DWI) is a functional magnetic resonance imaging (MRI) sequence. ⋯ Perfusion parameters derived from IVIM based on tumor edge ROI may offer additional value in differentiation in cervical cancer, and the IVIM perfusion parameters showed moderate positive correlations with quantitative perfusion parameters from DCE-MRI, while f and fD* showed promising significance.

The application of the ultrasound elastography and Thyroid Imaging Reporting and Data System (TI-RADS) classification further expands the scope of ultrasound differential diagnosis between benign and malignant thyroid nodules. ⋯ The SWE technique can be used to further determine the benign and malignant nature of TI-RADS 4 lesions, providing further reference for the choice of clinical treatment. The TI-RADS classification system corrected by SWE is more significant in the diagnosis of benign and malignant thyroid nodules.

The application of conventional magnetic resonance imaging (MRI) in glioma grading is limited and non-specific. ⋯ Combining conventional MRI, TA of DCE-MRI, and ITSS on SWI may help to improve the differentiation between LGGs and HGGs.

Reduction in gadolinium (Gd) contrast agents is wanted due to the uncertainty of the potential side effects. ⋯ We found a dose-response relationship between single and double doses of Gd-DTPA2- using 3-T in knee OA patients, similar to the findings at 1.5-T. Compared to the T1-relaxation time at 3-T without contrast (1240 ms), this further separation between OA and normal cartilage indicates that "single dose" dGEMRIC could be sufficient for cartilage health assessment at 3-T.
