Mediastinal lymph nodes: assessment with diffusion-weighted MR imaging.
To prospectively determine whether the diffusion-weighted magnetic resonance imaging is useful to distinguish between malignant and benign mediastinal lymph nodes. ⋯ Diffusion-weighted MR with ADC value and signal intensity can be useful in differentiation of malignant and benign mediastinal lymph nodes.

Combined T2-weighted and diffusion-weighted MRI for diagnosis of urinary bladder invasion in patients with prostate carcinoma.
To retrospectively determine the diffusion-weighted imaging (DWI) characteristics and apparent diffusion coefficient (ADC) values of prostate carcinoma (PCa) with urinary bladder invasion, and to compare the accuracy of T2-weighted MRI alone and T2 combined with DWI for predicting urinary bladder invasion. ⋯ Urinary bladder invasion had lower ADC values compared with normal urinary bladder wall. T2 images plus DWI is significantly better than T2-weighted imaging alone in the detection of urinary bladder invasion in patients with PCa.

Prostate cancer detection with multi-parametric MRI: logistic regression analysis of quantitative T2, diffusion-weighted imaging, and dynamic contrast-enhanced MRI.
To develop a multi-parametric model suitable for prospectively identifying prostate cancer in peripheral zone (PZ) using magnetic resonance imaging (MRI). ⋯ Using logistic regression, an objective model capable of mapping PZ tumor with reasonable performance can be constructed.

Functional magnetic resonance imaging of the spinal cord during sensory stimulation in diabetic rats.
To determine if differences exist between control and diabetic rats in functional magnetic resonance imaging (fMRI) activity of the spinal cord and if fMRI can provide a means of early detection of diabetic neuropathy. ⋯ The results of this study are consistent with reports that primary afferent input to the spinal cord is diminished by diabetes, and suggest that BOLD fMRI may be useful in early detection of diabetic neuropathy.

Comparative StudyUsefulness of the application of the BLADE technique to reduce motion artifacts on navigation-triggered prospective acquisition correction (PACE) T2-weighted MRI (T2WI) of the liver.
To evaluate the effects of the application of the BLADE (Siemens, Siemens Medical Systems, Erlangen, Germany) technique, a technique to reduce motion artifacts, on navigator-triggered prospective acquisition correction (PACE) T2-weighted MRI (T2WI) of the liver. ⋯ The BLADE technique could improve image quality by reducing motion artifacts on hepatic MRI without affecting the diagnostic performance.
