Now in the dignosis and differentiate of the renal neoplasm, ultrasound has been the first choosed. It has very important clinical sense. From 1990, CDE has been used in the clinic. Later, new and cubic 3D imaging has been used in the clinic, too. This advanced technology makes progresses in the ultrousound. CDE and 3D imaging providing blood of low power mode and cubic mode. Display the organ and the tumor's flow character. With the 3D and CDE. This study wanted provided a method the diagonosis and differentiate to the renal neoplasm.Methods25 cases of renal cell carcinoma, 3 cases of adnoma and 2 cases of harmatoma was choosed from December 2000 to March 2002, identified by pathology after operation. Male; 19 cases, female; 11 cases. Age; 14-70 year. Analysising the blood flow distribute and morphology in the tumor, with the CDE, two blood flow is divided inside flow. Perephery flow diffuse flow. In side flow pattern divide aspect, stripe,irregulate. Inside flow divide grade; without flow. I; 1 -2 aspect flow and single stripe flow. II: lot of flow, 2 - 3 or more stripe flow, like net or branch. After analysising line of low with CDE, reconstract 3D flow, using 3D function key.ResultsRenal CDE manifestation in renal flow (benign tumor is renal adenoma and harmatoma) renal tumor flow distribution; most of renal cell carcinoma is diffuse flow. Most of renal benign tumor is periphery flow. Morphology inside renal tumor; 60% renal cell carcinoma is irregular flow. 80% renal benign tumor is without flow. Inside tumor, flow divide grades inside renal tumor: there is flow inside all renal cell carcinoma. 84% is II or III grade flow. However, 20% is I grade flow, 80% is without flow inside renal benign tumor. Flow grade is significant inside renal cell carcinoma and renal benign time. This study investigates 25 cases renal cell carcinoma with 3D - CPA, Divide 2 grade. 1. sufficient flow; 19 cases (76% ) 3D - CPA and irregular or net flow. 2. Insufficient flow. 6 cases (24% ) 3D -CPA show: few and scattered flow branch inside tumor and periphery tumor. There is one section flow in CDE. However there is spatial flow in 3D - CPA. 3D - CPA can show tumor flow?distribution and pattern more direct and complete.DiscussionCDE is Doppler's technology showing flow pattern with Doppler's power sign. CDE show Doppler's power, power account on red cellquantity. So CDE has lots of character; 1. Increase flow sensitivity. 2. Without confuse. 3. Relative independent on angle because of superior character.CDE can show low velocity and zero velocity flow, so, it show flow continue it can show little vessel and tortuous vessel different tumor flow construction and blood. Supply has itself character. They are base of tumor survive and grow, so investation tumor blood supply can help to diagnosis and inside differential. In angiography, 92% renal cell carcinoma there is regeneration tumor vessel. And lots of abnormal vessel, including vessel tortuous and interrupt, crowed, shunt they show; renal cell carcinoma have plenty of tumor vessel. And vessel construct is abnormal.CDE show renal two in this study: research of renal tumor by CDE reveal; tumor blood signals are showed in 25 cases renal carcinoma , and the shape of flow is varied, including distorted : cracked. But the revealing rate of blood flow in benign renal tumor is low. And the shape of flow is simple, it likes star, there is obviously different in blood flow shape, in contrast with renal carcinoma. In this study, we can divide inner blood flow of tumor into 4 levels, from 0 ~ III. I: blood flow is little, II ~ III: blood flow is lot, 84% , inner blood flow of renal carcinoma are II ~ III, but, benign tumor of renal are 0 ~ I. This conclusion shows, there is obviously different in dividing of blood flow between carcinoma and benign tumor of renal.Fro... |
