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.

The number of citations that an article has received can be used to evaluate its impact on a particular research area. ⋯ Our study presents a detailed list and analysis of the 100 top-cited articles on MR, which provides an insight into historical development in this field.

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.

Percutaneous kyphoplasty (PKP) has been widely used to osteoporotic vertebral compression fractures (OVCFs). No previous investigations have reported the incidence and risk factors of facet joint violation (FJV) caused by PKP. ⋯ The placement of a puncture trocar can cause FJV in patients with OVCFs and impact clinical outcomes after PKP. Special attention should be given to patients with an FJA > 55°, a PD < 5 mm, and a DEF < 5 mm.

Usefulness of ultrasound (US)-guided mass targeting and computed tomography (CT)-guided ice-ball monitoring in percutaneous cryoablation (PCA) for renal cell carcinoma (RCC) is still uncertain. ⋯ PCA using US-guided targeting and CT-guided ice-ball monitoring may allow acceptable local tumor control for RCC, as a radiation-reducing strategy.
