[The use of new turbo spin-echo pulse sequences with and without fat suppression in the diagnosis and staging of prostatic carcinoma].
MR studies using turbo spin-echo pulse sequences (TSE) were performed on 27 patients with histologically confirmed prostate cancer. A prospective study was conducted in 15 patients who underwent radical prostatectomy. Turbo SE pulse sequences generate strongly T2-weighted images of excellent quality with reduction of measurement time by a factor of 4-6. A comparison with standard T2-weighted spin-echo pulse sequences indicated an objective improvement in the contrast of pathological structures (p < 0.001). With respect to differentiation of stages T2 and T3 (TNM) during pathohistological correlation, sensitivity of 80%, specificity of 40% and an accuracy rate of 67% were obtained. Sensitivity of 71% and specificity of 75% were obtained when decoding cases of infiltration into the seminal vesicles, with an accuracy rate of 73%.
