[Abstract] Objective: To evaluate the conventional MR imaging, MR spectroscopy (MRS) and diffusion-weighted imaging (DWI) of incidentally detected prostate carcinoma in the central gland of prostate.Materials and Methods: The clinical and imaging data of 9 patients with incidentally detected prostate carcinoma (IDPC) who underwent transurethral resection of the prostate were analyzed retrospectively. The manifestation of conventional MRI, MRS and DWI were observed, the corresponding value of (Cho+Cre)/Cit(CC/C), the ADC value of the central gland and the minimal ADC value were calculated.Results: The mean CC/C value of IDPC was 1.04±0.28, and the range of it was 0.65-1.45. The mean and the range of the ADC value of the central gland were (1.48±0.18)×10-3 mm2/s and (1.16-1.67)×10-3 mm2/s. The mean and the range of the minimal ADC value were (1.15±0.10)×10-3 mm2/s and (0.99-1.25)×10-3 mm2/s.Conclusion: MRS and DWI have some limitations in the diagnosis of the incidentally detected prostate carcinoma in the central gland of prostate.
