Evaluation of intratumoral hemodynamics with color Doppler imaging in patients with colorectal carcinoma: comparison between waveform analysis and histopathologic characteristics.

Purpose: We studied the relation between intratumoral hemodynamics and histopathologic characteristics in patients with colorectal carcinoma.

Methods: A series of 82 patients with 28 well-differentiated adenocarcinomas, 40 moderately differentiated adenocarcinomas, 10 poorly differentiated adenocarcinomas, and 4 mucinous adenocarcinomas underwent color Doppler examination and surgical treatment. The waveform of blood flow in the thickened wall of the colon was analyzed by determining the maximum velocity (Vmax) and resistance index (RI).
