Can pre-operative contrast-enhanced dynamic MR imaging for prostate cancer predict microvessel density in prostatectomy specimens?

abstract：:Two cases of agenesis of the horizontal segment of the left portal vein are reported. This very rare vascular anomaly probably corresponds to an embryological variation rather than to an obstruction of the left portal vein. In almost all cases liver ultrasonography is sufficient for identifying such vascular abnormali...
