多b值弥散成像诊断中央区前 列腺结节的价值
Value of of Different B Value of Diffusion-Weighted Imaging in the Diagnosis of Central Prostate Nodules
摘要
Abstract
Objective To evaluate the diffusion-weighted imaging with different B value in diagnosis of nodular hyperplasia and cancer in the central region of prostate.Methods A total of 37 patients with suspected prostatic central malignant nodules were evaluated with diffusion weighted imaging in 3.0 T magnetic resonance imaging. All the patients were confirmed by pathological examination. Conventional magnetic resonance imaging and diffusion-weighted imaging were analyzed in each patient. The apparent diffusion coefficient (ADC) of the lesion area was measured. The differences of ADC value in benign and malignant nodules were analyzed. The relationship between Gleason score and ADC value was discussed.Results 52 nodules were found in 37 patients, including 25 benign nodules and 27 malignant nodules. When b value was 2000, the sensitivity, specificity and accuracy were 70.90%, 89.10% and 91.32%, respectively, with the ADC value of 1.0×10-3mm2/s. The ADC value of benign and malignant nodules showed a downward trend with the increase of b value without statistical significance. The ADC value of malignant nodules was negatively correlated with Gleason score.Conclusion The ADC value of malignant prostatic nodules is lower than that of hyperplastic nodules, and high B diffusion imaging is of great value in differential diagnosis of prostate cancer.关键词
