Randomized Controlled Trial Comparative StudyComparison of diffusion-weighted MRI and MR volumetry in the evaluation of early treatment outcomes after preoperative chemoradiotherapy for locally advanced rectal cancer.
To compare diffusion-weighted imaging (DWI) and magnetic resonance (MR) volumetry for predicting treatment outcomes of locally advanced rectal cancers with preoperative chemoradiotherapy (CRT). ⋯ Early tumor volume reduction rate at the second week after CRT initiation may be a better indicator than DWI based on the mean ADC measurements for predicting CRT treatment outcome.

Randomized Controlled Trial Comparative StudyPreoperative detection of prostate cancer: a comparison with 11C-choline PET, 18F-fluorodeoxyglucose PET and MR imaging.
To compare (11)C-choline positron emission tomography (C-PET), (18)F-fluorodeoxyglucose PET (FDG-PET), and MR imaging in the preoperative detection of prostate cancer. ⋯ MR imaging should be primarily performed in the preoperative detection of prostate cancer. C-PET and FDG-PET did not improve the detection.

Randomized Controlled Trial Multicenter Study Comparative StudyComparison of gadodiamide-enhanced MR angiography to intraarterial digital subtraction angiography for evaluation of renal artery stenosis: results of a phase III multicenter trial.
To evaluate the efficacy and safety of 0.1 mmol/kg gadodiamide administration for contrast-enhanced magnetic resonance angiography (MRA) in detecting hemodynamically relevant renal artery stenosis (RAS) when compared with intraarterial digital subtraction angiography (IA-DSA) as the gold standard. ⋯ Gadodiamide administration at the labeled dose of 0.1 mmol/kg for contrast-enhanced MRA achieved equivalent results compared to IA-DSA in evaluation of RAS and was well tolerated.

Randomized Controlled Trial Multicenter Study Comparative StudyEnhancement of liver parenchyma after injection of hepatocyte-specific MRI contrast media: a comparison of gadoxetic acid and gadobenate dimeglumine.
To compare enhancement of liver parenchyma in MR imaging after injection of hepatocyte-specific contrast media. ⋯ In the delayed, hepatocyte-specific phase, liver enhancement after injection of gadoxetic acid was superior to that obtained with gadobenate dimeglumine.

Randomized Controlled Trial Multicenter Study Comparative StudyMulticenter, double-blind, randomized, intra-individual crossover comparison of gadobenate dimeglumine and gadopentetate dimeglumine in MRI of brain tumors at 3 tesla.
To prospectively compare 0.1 mmol/kg doses of gadobenate dimeglumine and gadopentetate dimeglumine for contrast-enhanced MRI of brain lesions at 3 Tesla (T). ⋯ Brain lesion depiction at 3T is significantly improved with 0.1 mmol/kg gadobenate dimeglumine.
