Randomized Controlled Trial
Triple-negative breast cancer: correlation between MR imaging and pathologic findings.
To retrospectively evaluate the magnetic resonance (MR) imaging findings of "triple-negative" breast cancer (ie, cancer that is estrogen receptor [ER] negative, progesterone receptor [PR] negative, and human epidermal growth factor receptor 2 [HER2] negative) and to compare them with those of breast cancers that are ER positive, PR positive, and HER2 negative. ⋯ Several MR imaging features might be used for detecting triple-negative breast cancer.

Randomized Controlled Trial Multicenter Study Comparative Study
Lumbar spine: reliability of MR imaging findings.
To characterize the inter- and intraobserver variability of qualitative, non-disk contour degenerative findings of the lumbar spine at magnetic resonance (MR) imaging. ⋯ The interpretation of general lumbar spine MR characteristics has sufficient reliability to warrant the further evaluation of these features as potential prognostic indicators.

Randomized Controlled Trial
Self-expandable esophageal stent loaded with 125I seeds: initial experience in patients with advanced esophageal cancer.
To prospectively compare the response to treatment with a self-expandable esophageal stent loaded with iodine 125 ((125)I) seeds for intraluminal brachytherapy versus the response to treatment with a conventional self-expandable covered stent in patients with advanced esophageal cancer. ⋯ In patients with advanced esophageal cancer, treatment with an esophageal stent loaded with (125)I seeds, compared with that with a conventional covered stent, has potential benefit in that it allows a slightly longer relief of dysphagia and extended survival.

Randomized Controlled Trial Comparative Study
Pancreas: patient body weight tailored contrast material injection protocol versus fixed dose protocol at dynamic CT.
To prospectively compare the effect of a protocol with a fixed contrast material injection dose and one with a dose tailored to patient body weight on pancreatic enhancement at dynamic computed tomography (CT) of the pancreas. ⋯ The dose protocol tailored to the patient's body weight yielded satisfactory pancreatic and hepatic enhancement irrespective of patient weight.

Randomized Controlled Trial
Effectiveness of transforaminal epidural steroid injection by using a preganglionic approach: a prospective randomized controlled study.
To prospectively evaluate the short- and midterm effectiveness of transforaminal epidural steroid injection (TFESI) for lumbosacral radiculopathy with respect to injection level. ⋯ TFESI for lumbosacral radiculopathy with a preganglionic approach is more effective than TFESI with a ganglionic approach at short-term follow-up.
