Objective: To explore the clinical value of follow-up MR scans after radiotherapy for laryngeal carcinoma. Materials and Methods: To analyze follow-up MR appearances of the larynx in 37 patients of laryngeal cancer with pathological evidences after radiotherapy. Results: Eighteen patients received merely radiotherapy. Seventeen patients received laryngectomy and post-operation radiotherapy 6 to 8 weeks after operation. Two patients received radiotherapy because of recurrent carcinoma two years after operation. MR appearances showed edema with different degree at the sixth week, and extinct at the third to sixth months after radiotherapy. The affected range of tumor also reduced or disappeared gradually. Four patients showed chronic edema after 1 year, 1.5 years, 3 years and 6 years respectively. Recurrent tumors were found in two patients after merely radiotherapy and in five patients after operation and post-operation radiotherapy. One patient showed laryngeal stenosis with infection. Conclusion: Follow-up MR scans can provide reliable images about reactive edema, chronic lymphedema, laryngeal stenosis, improvement of the primary tumors and recurrent laryngeal carcinoma.

DOI:
Objective: To describe the radionuclide myocardial perfusion imaging(MPI) features of myocardial microvascular damage in the patients with essential hypertension and discuss the relationship between image characteristics and the severity of hypertension. Method: The 99Tcm-MIBI MPI features of resting imaging and nitroglycerin(NTG) intervention was described in 102 patients with essential hypertension by the method of qualitative and semi-quantitative scoring. Result: ①After NTG intervention, 68 and 170 MPI segments were reversed redistributed separately in CAG normal group and in CAG abnormal group. They accounted for 11.5% and 28.8% separately of all abnormal segments. The ratio of reverse redistribution had significant difference between the two groups(χ2=10.53, P<0.001). ②The MPI features in resting state had no significant difference with the image after NTG intervention in the patients with hypertension grade Ⅰ(t=1.81, P＞0.05), but the MPI features of the resting state had significant difference with the image after NTG intervention in the patients with hypertension grade Ⅱ(t=8.23, P<0.001) and grade Ⅲ(t=7.55, P<0.001). ③ The average scores of SRS, SSS and SDS were increased separately from 2.83±1.25, 5.67±2.29 and -4.35±2.11 to 15.32±6.54, 24.19±7.36 and -14.62±3.82 with aggravation of high blood pressure. The average scores of SRS, SSS and SDS had significant difference among the three groups(F=25.77, P<0.05; F=27.69, P<0.01; F=26.34, P<0.01). The scores had significant difference between SSS and SRS in each hypertension group(t=4.35, P<0.001; t=7.78, P<0.001; t=6.17, P<0.001). Conclusion: ①The segmental number and severity of myocardial ischemic in 99Tcm-MIBI MPI can reflect the extent of coronary microvascular injury in the patients with essential hypertension. ②Reverse redistribution is the characteristic 99Tcm-MIBI MPI feature in the patients with myocardial microvascular damage after NTG intervention.

DOI:
Objective: To assess left ventricular longitudinal, radial, circumferential strain and twist in rabbit models of left ventricular hypertensive hypertrophy and diastolic heart failure induced by abdominal aortic constriction using two-dimensional speckle tracking echocardiography(STE). Methods: Thirty-four male New Zealand rabbits were randomly divided into three groups: sham-operation group(control group, n=10), diastolic heart failure group(DHF group, n=12) and left ventricular hypertrophy group(LVH group, n=12). LVH and DHF were induced by suprarenal abdominal aortic constriction. After rabbit models were established, left ventricular strain and twist parameters were measured by STE. And left ventricular catheterization was performed. Results: Compared with sham-operation group, in LVH group, only longitudinal strain decrease significantly, in DHF group, longitudinal and radial strain both decreased significantly. Ptw increased significantly in LVH group, but increased nonsignificantly in DHF group. Conclusions: STE is useful in evaluating left ventricular performance in pressure-overload rabbit.

DOI:
Objective: To investigate the dose of first-pass perfusion and the best delayed scanning time. Thereby, the purpose is to get a better cardiac perfusion MRI images and the best delay-enhanced images. Method: Five experimental pigs with myocardial infarction underwent two MR myocardial first-pass perfusion imaging, the contrast agent dose were 0.05mmol/kg and 0.1mmol/kg respectively. Ten experimental pigs with myocardial infarction underwent delayed enhanced MR imaging at 5min, 10min, 30min, 40min time point. The results were analyzed statistically. Result: There was statistical difference(P<0.05) between the two groups(0.05mmol/kg and 0.1mmol/kg) in detection of the myocardial perfusion decrease or defect on the first-pass MR perfusion imaging. The data of the delayed enhancement MR imaging in different scanning time showed. ①The signal values were statistically significant between 10 minutes and 5 minutes, 40 minutes and 30 minutes; ②The signal values of myocardial infarction showed rise in the stage of 5～10 minutes; and the signal values were relatively stable in the 10～30 minutes; During the stage of 30～40 minutes, the signal value of myocardial infarction showed a clear downward trend compared with the previous time. Conclusion: The perfusion imaging quality of the dose of the 0.1mmol/kg group is better than the 0.05mmol/kg group. It can detect more myocardial perfusion defects. Delayed time between 10～30min is the best scanning time to the delayed enhancement MR imaging. These are helpful in the assessment of myocardial viability using MR first-pass myocardial perfusion imaging and delayed enhancement MR imaging.

DOI:
Objective: To analyze the imaging findings of benign renal angiomyolipoma(AML) with minimal fat. Materials and Methods: Ultrasonography, CT and MRI findings in 20 patients(6 males, 14 females) of benign renal AML with minimal fat confirmed by surgery and pathology were analyzed retrospectively. All patients underwent ultrasonography. Unenhanced and biphasic CT scans were performed in 12 patients, 1 patient underwent biphasic CT scan only. Unenhanced and dynamic contrast-enhanced MRI were performed in 12 patients, 1 patient underwent unenhanced MRI only. Results: Ten lesions(50%) were of irregular or ellipsoidal shape. The tumor-kidney interface was straight in 9 lesions(45%). Fifteen lesions protruded from the renal margin, and 7 lesions(46.7%) with restricted growth pattern or “fungus sign”. Compared with the surrounding renal parenchyma, 9 lesions(75%) showed homogeneously high attenuation on unenhanced CT images. Of the 13 patients examined with MR imaging, all were hypo-intense on T2WI, homogeneous(4 lesions, 30.8%) or with micro hyper-intense spot(9 lesions, 69.2%). On double-echo GRE chemical shift imaging, focal or diffuse signal suppression were found in 5 lesions(41.7%). All lesions showed homogeneous or reticular enhancement on biphasic CT and dynamic contrast-enhanced MRI images. Twelve lesions(60%) showed hyperechogenicity on ultrasonography, and 18 lesions(90%) were homogeneous. Tortuous and enlarged vessels were found in 3 lesions(15%). Conclusion: Benign renal AML with minimal fat usually has irregular or non-expansive growth pattern, homogeneous hyperechogenicity on ultrasonography, homogeneously high attenuation on unenhanced CT images, homogeneously hypointense on T2WI with micro hyperintense spots, homogeneous or reticular prolonged enhancement on contrast-enhanced CT and MRI images, female predominance, and tortuous or enlarged vessels were found occasionally.

WANG Hong-bo;CHEN Yan-jun;WU Ze-wen;XIAO Lin
DOI:
Objective: To investigate the proton magnetic resonance spectroscopy(1H-MRS) features of benign and malignant soft tissue tumors in human and to explore its feasibility and application value in the differential diagnosis of soft tissue tumors. Materials and Methods: Forty-four cases were included in the study and divided into three groups. There were 10 cases in nomal group, 14 cases in benign tumor group and 20 casese in malignant tumor group. MRI and 1H-MRS were performed in all cases. The 1H-MRS features of all the 44 cases were analyzed. Cho/Cr and Lipid/Cr were calculated on workstation and a statistic test was done. We caculated the cell density of 30 soft tissue tumors and performed pearson correlation analysis between the cell density and Cho/Cr value. Results: The Cho/Cr value in the malignant tumor was larger than that in the benign tumor and normal muscle, but the Lipid/Cr value was smaller than that in the benign tumor and normal muscle. The differences of Cho/Cr value and Lipid/Cr value between malignant and benign soft tissue tumors were statistically significant(P<0.01). In contrast to benign tumor group, 1H-MRS revealed increased Cho, Lac and decreased Lipid and Glc peak in the 12 cases of malignant tumor. The average cell density was 152/FOV in the malignant tumor group and 57/FOV in the benign tumor group. The value of the cell density had a significant positive correlation with the Cho/Cr value in soft tissue tumors(r=0.891, P<0.001). Conclusion: The benign and malignant soft tissue tumors in human showed great difference in 1H-MRS. 1H-MRS has high application value in the differential diagnosis of soft tissue tumors.
