Timing and course of neonatal intracranial hemorrhage using real-time ultrasound.

abstract：:To evaluate the ability of ultrasonography (US) to determine venous tumor extension, we studied 120 consecutive patients with renal neoplasms. The incidence of renal vein involvement in this group was 18%; caval tumor extension occurred in 11% of the patients. Real-time US clearly visualized the entire retrohepatic in...
