Randomized Controlled Trial Comparative Study Clinical TrialIntra-individual crossover comparison of gadobenate dimeglumine and gadopentetate dimeglumine for contrast-enhanced magnetic resonance angiography of the supraaortic vessels at 3 Tesla.
To compare gadobenate dimeglumine (Gd-BOPTA) and gadopentetate dimeglumine (Gd-DTPA) for contrast-enhanced magnetic resonance (MR) angiography of the supraaortic vessels at 3 Tesla. ⋯ Significantly improved image quality and contrast enhancement is achieved at 3T with 0.1 mmol/kg Gd-BOPTA compared with 0.1 mmol/kg Gd-DTPA.

Comparative StudyComputed tomography, positron emission tomography, positron emission tomography/computed tomography, and magnetic resonance imaging for staging of limited pleural mesothelioma: initial results.
To evaluate and compare the role of computed tomography (CT), positron emission tomography (PET), PET/CT, and magnetic resonance imaging (MRI) in the correct staging of patients with limited malignant pleural mesothelioma (MPM). ⋯ PET/CT makes it possible to stage patients with limited MPM with high accuracy and low interobserver variability.

Evaluation of ovarian tumors by proton magnetic resonance spectroscopy at three Tesla.
The purpose of this study was to determine the feasibility of acquiring in vivo proton magnetic resonance spectroscopy of ovarian lesions at a magnetic field strength of 3 Tesla (T). The goal was to provide potentially diagnostic biochemical information that may aid in the characterization of ovarian neoplasms detected during clinical magnetic resonance imaging scanning. ⋯ Spectroscopy of ovarian masses can be recorded at 3.0 T with acceptable spectral quality and good signal-to-noise ratio. There are stringent technical considerations to be considered in obtaining good spectral quality. Further experience with a larger and more biologically variable range of tumors needs to be undertaken to determine the final clinical utility of this technique, but initial results from this small cohort are promising.
