RATIONALE: Diagnostic procedures, such as dynamic contrast-enhanced magnetic resonance imaging or DCE-MRI and diffusion-weighted imaging or DWI, may provide images of prostate cancer or any cancer that remains after biopsy.
PURPOSE: This trial studies repeated DCE-MRI and DWI in patients diagnosed with prostate cancer.

- Determine the test-retest performance, assessed by the repeatability coefficient [RC] of K^trans and gadolinium curve (IAUGC90^bn) and measured by median pixel values of the whole prostate.
- Determine the test-retest performance, assessed by the RC of diffusion-weighted imaging (DWI) metrics D(t) and measured by median pixel values of the whole prostate.
- Determine the test-retest performance, assessed by RC of K^trans, IAUGC90^bn, and D(t), and measured by median pixel values of the dominant prostate tumor.
- Determine the effect of reader on the RC of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) and DWI metrics for whole prostate and tumor nodule target lesion.
- Determine whether T1-dependent or T1-independent methods for gadolinium quantification in DCE-MRI studies produce differing values for the RC for K^trans and IAUGC90^bn.
- Explore the correlation between DCE-MRI and DWI metrics for both whole prostate and dominant tumor nodule as target lesions. (Exploratory)
- Determine whether the "coffee break" approach toward test-retest analysis of quantitative DWI provides a reasonable estimate of the RC of D(t)of the whole prostate, using as the gold standard the RC of D(t) obtained between the two separate MRI visits. (Exploratory)
OUTLINE: This is a multicenter study. Patients are stratified according to MRI vendor used (Siemens vs GE vs Philips).
Patients receive gadolinium-based contrast IV and undergo DCE-MRI* and DWI 2 imaging at 2-14 days apart prior to treatment initiation. A central reader evaluation of the 2 successive scans is then conducted.
NOTE: *At the discretion of the participating sites, the initial MRI visit (MRI SCAN 1) may be supplemented with endorectal-coil imaging per institutional norms.

- Repeatability assessment of DCE-MRI metrics Ktrans and blood-normalized initial area under the gadolinium curve (IAUGC90bn) and the DWI metric D(t) [ Time Frame: 2 to 14 Days ]The repeatability coefficient (RC) and its 95% confidence interval (CI) will be estimated for each metric [ ktrans, IAUGC90bn] using the method of Barnhart and Barboriak, 2009
- Test-retest performance, assessed by the RC of Ktrans, IAUGC90bn, and D(t), and measured by median pixel values of the prostate tumor [ Time Frame: 2 to 14 Days ]The repeatability coefficient (RC) and its 95% confidence interval (CI) will be estimated for each metric using the method of Barnhart and Barboriak, 2009
- Comparison between T1-dependent or T1-independent methods for gadolinium quantification produce differing values for the RC for Ktrans [ Time Frame: 2 to 14 Days ]The repeatability coefficient (RC) and its 95% confidence interval (CI) will be estimated for each metric ktrans] and each method [ independent and dependent] using the method of Barnhart and Barboriak, 2009
