TL;DR: Color Doppler sonography was useful for evaluating hepatic tumor hemodynamics as seen at arteriography, and peak systolic velocity may be useful in differentiating malignant hepatic tumors from hemangiomas.
Abstract: We studied benign and malignant hepatic tumors with color Doppler sonography and arteriography in order to correlate color Doppler flow characteristics with tumor hemodynamics (vascularity, arteriovenous shunting, and portal vein involvement) shown by arteriography. We also evaluated the usefulness of color Doppler flow characteristics in discriminating between tumor types.We performed color Doppler sonography and hepatic arteriography in 58 patients with 72 hepatic lesions larger than 2.0 cm in diameter. Differences in pulsatile flow (peritumoral or intratumoral) and the highest systolic peak flow velocities reached were evaluated on color Doppler sonograms and compared with arteriographic findings.Color flow sonograms were obtained in 43 of 45 hepatocellular carcinomas, 15 of 16 cholangiocellular carcinomas or hepatic metastases, and six of 11 hemangiomas. Mixed peritumoral and intratumoral pulsatile flow was shown by arteriography in highly vascular tumors. The mean peak systolic flow velocity seen in ...

TL;DR: The relationship between blood flow and the localization of thrombosis and atherosclerosis in vivo was investigated using the approach and techniques of microrheology and it was shown that stagnation points are found in regions of disturbed flow at various sites in the arterial and venous circulations.

TL;DR: Lumen geometry is not the sole determinant of coronary blood flow at 90 min following thrombolytic administration, and other variables such as the location of the culprit artery, the duration of patency, a pulsatile flow pattern and thrombus are also related to slower flow.
