Coronal diffusion-weighted magnetic resonance imaging of the kidney: agreement with axial diffusion-weighted magnetic imaging in terms of apparent diffusion coefficient values.

Background: Coronal diffusion-weighted magnetic resonance imaging (DW-MRI) and apparent diffusion coefficient (ADC) values have gradually become applied (following conventional axial DW-MRI) in the renal analysis. To explore whether data obtained using coronal DW-MRI are comparable with those derived using axial DW-MRI, this preliminary study sought to assess the agreement in renal ADC values between coronal DW-MRI and axial DW-MRI.

Methods: Thirty-four healthy volunteers were enrolled in the study; written consents were obtained.

[MR appearance of multifocal clear cell renal cell carcinoma].

Objective: To document the magnetic resonance (MR) imaging features of multifocal clear cell renal cell carcinoma (RCC).

Methods: The MR findings of 11 cases of pathologically-proved multifocal clear cell RCCs were reviewed retrospectively from January 2008 to December 2010. All patients underwent MR in a 1.

[Magnetic resonance imaging findings of Chromophobe renal cell carcinoma].

Objective: To document the MRI features of Chromophobe cell carcinoma and to explore whether MR features vary with the tumor size.

Methods: MRI features of 34 patients (16 male, 18 female, age range from 24 - 61, average age is 49 years old), totally 35 focuses with histologically proved chromophobe cell carcinoma were studied retrospectively. All the patients underwent MR plain and dynamic contrast-enhanced scan before their surgery.
