Comparative Study
[The clinical value of 3 tesla diffusion-weighted magnetic resonance imaging in the diagnosis of prostate cancer].
Diffusion-weighted imaging (DWI) is a magnetic resonance imaging (MRI) method and is considered potentially useful for detecting prostate cancer. We evaluated the clinical value of DWI with apparent diffusion coefficient (ADC) maps in addition to T2-weighted imaging (T2WI) using 3 tesla (3 T) MRI. Thirty-three patients with elevated prostate specific antigen were evaluated by MRI with T2WI and DWI prior to transperineal template-guided mapping biopsy. ⋯ Mean ADC values were significantly different between cancer positive and negative cores (p<0.001). The ADC value showed a negative correlation with increasing tumor length (p=0.0047). Although further study with a large number of patients is necessary, DWI/ADC using 3 T MRI is a useful tool for detecting prostate cancer.
