Clinical application of blood flow gradation by three-dimensional reconstruction of power Doppler imaging in monitoring acute rejection of renal transplantation / 中华超声影像学杂志

Objective To study the clinical value of three-dimensional vascular reconstruction of power Doppler imaging in monitering acute rejection of renal transplant.Methods Eighty-eight renal allograft patients were studied by three-dimensional vascular reconstruction and graded the vascular flow.Results The ratio of successful renal transplant three-dimensional vascular reconstruction reached 95.5% in 88 cases.Blood flow gradation was 4-5 levels in 30 controls and 0-4 levels in 58 patients with acute renal transplant rejection. Blood flow gradation was closely relevant to the time when the blood flow began to improve and the renal function began to restore after treatment, value of r being -0.9224 and -0.9223 respectively (P
