DOI:
Objective: To study the relationship between left ventricular energy(LVE) and energy efficiency(EE) in patients with coronary heart disease and cardiac reserve. Methods: Modified models of LVE and EE under Doppler echocardiography were constructed according to pressure-volume potential energy theory based on cardiac catheter. LVE index and ejection fraction(EF) in 70 patients with different numbers of diseased coronary artery based on coronary angiography and various cardiac function classification of NYHA and 28 normal individuals were investigated by comparison of echo-method with catheter-method, different cardiac function classification of pressure-volume loop energy figures were drawn. Results: Total energy(TE), stroke work(SW), end-systolic potential energy(ESE), filling energy(FE) and EE determined by echo-method were highly coincided and related with those by catheter-method(r=0.80~0.91). Increase of ESE, FE and TE, decrease of EE and EF and right-up shift of P-V loops showed gradually as numbers of diseased vessels increasing and NYHA classification enlarged. Sensitivity of prediction of abnormal EE for different NYHA classification is significantly higher than that of abnormal EF(P<0.05). Conclusion: LVE and EE by echo-method are reliable and feasible and have higher advantage of EF to evaluating cardiac reserve of coronary heart disease.

MA Wei;ZHAO Gui-xin;FENG Yan-li;WANG Xiao
DOI:
Objective: To explore the optimal methods and pressure for colon insufflation in computed tomographic colonography. Material and Methods: Eight volunteers(4 men, 4 women; mean age, 44.4 years; range, 40~50 years). Insufflation of the colon was performed using the machine(Compute Remote Controlling Enema Taxis Instrument) through catheter(double channel Foley balloon indwelling latex catheter). When people underwent CT colonography, we choose the highest pressure which did not cause undue people discomfort for the beginning pressure. We should hold the pressure until finishing the scanning. Then we reduced pressure for the other scanning. We reduced 7.5mmHg per time until the pressure is 30mmHg. Results: Double channel Foley balloon indwelling latex catheter is placed in the rectum. During scanning, air was insufflated under the same pressure which was kept to the end. Under different atmospheric pressure: 52.5mmHg, 40mmHg, 37.5mmHg, 30mmHg. The distensibility of colon did not have obvious difference. After scanning, the time when the discomfort of abdomen disappeared was obvious difference between the men’s and the women’s. Conclusions: During scanning, air was insufflated under the pressure which was hold to the end. The method can hold the stability of colon’s distensibility, and it make sure that the examination of CTVE is successful. The pressure of colon insufflation should not be according to the patient maximum tolerance. The pressure we chose was 30mmHg. We placed double channel Foley balloon indwelling latex catheter in the rectum. The gas bag of catheter can prevent the catheter from dislodging and reduce the air which went out between catheter and anus. After scanning, the time when the discomfort of abdomen disappeared was different. The women’s is longer than the men’s.

LI Zhong-xin;YU Shu-jing;MA Guo-jun
DOI:
Objective: To study the clinical application value of 64 multislice spiral CT(MSCT) in evaluating the bridge vessel of coronary artery. Method: Twenty-one patients after bypass operation of coronary artery(77 bridge vessel, including 20 internal mammary artery bridge, 1 radial artery bridge and 56 great saphenous vein bridge) received 64 multislice spiral CT angiography(CTA). The average heart rate of patients is (60±5)/min scanning. The range of scanning is from internal mammary artery to 2cm below diaphragm. Two experienced doctors evaluate the degree of opening and stenosis of bridge vessel of coronary artery. 9 patients who had been found bridge vessel or distal stoma of coronary artery stenosis(≥50%) by MSCT accepted traditional coronary artery angiography at the same time. Result: CTA was performed successfully in all of the 21 patients. Differernt degree of stenosis or obstruction of the main coronary artery and main branch in all of the 21 patients were showed by CTA. Sixty-two bridge vessels of coronary artery are open and smooth. 10 were obstructed(including 2 internal mammary and 8 vein bridge). 3 were stenotic(≥50%) in proximal end anastomotic stoma of bridge vessel. 2 were stenotic in distal anastomotic stoma. 6 vessels had restenosis or obstruction in distal coronary artery of anastomotic stoma. The results of CAG and CTA are the same in 9 patients. The accuracy of CTA in evaluating the stenosis (≥50%) or obstruction was 100%. Conclusion: CTA can evaluate the bridge vessel of coronary artery and the degree of restenosis of stoma accurately. CTA can discover the location of proximal end stoma directly and guide the approach of CAG after bypass operation of coronary artery. CTA is the method of choice to evaluate the abnormalities of the bridge vessel of coronary artery.

DOI:
Objective: To evaluate the value of multiple spiral CT(MSCT) perfusion imaging in the pre-surgical diagnosis, staging, assessing the renal blood flow and the tumor angiogenesis of renal cell carcinoma(RCC). Methods: The study included 38 cases of RCC, 18 cases of renal pelvic carcinoma(RPC) and 8 cases of renal angiomyolipoma(RAML) proved by surgery and pathology. Target-slice dynamic perfusion scanning was performed in all patients before surgery. Regions of interest(ROI) were drawn within the tumor, the region of normal area adjacent to the tumor and the other side. Relevant parameters including blood flow(BF), blood volume(BV), mean transit time(MTT）, permeability surface(PS） and time-density curve(TDC) were analyzed using perfusion software. Result: ①There were significant association for BF, BV and PE between different tumor cell grades, RCC and normal renal cortex.②Of the 38 RCC, especially the grade II and III, the mean BF, BV, PS and peak enhancement(PE） value were higher than that of RPC. ③The time of peak(PT） of RCC were obviously earlier than that of normal renal cortex, RPC and RAML. There were significant differences between them. ④The MTT value of grade II and III RCC were obviously lower than that of normal renal cortex. There were no significant differences of MTT between RCC, RPC and RAML. ⑤Perfusion of RCC was much higher than that of RPC and RAML. Conclusion: There are distinctive characteristics of MSCT perfusion imaging in RCC, which help to assess the renal blood flow and the tumor angiogenesis and provides useful information for pre-surgical diagnosis and staging of RCC. MSCT perfusion imaging is a promising technique for clinical evaluation and prediction of prognosis in RCC.
