Chinese Journal of Interventional Imaging and Therapy.2010;7(1):5-9.

Objective To assess the value of rigid wall and outer coarse signs in 64-slice CT for pre-operation stages of colorectal carcinoma. Methods One hundred and twenty-three colorectal carcinoma patients underwent 64-slice CT;then rigid wall and out coarse signs were evaluated respectively. The tumors were grouped according to the postoperative pathologic infiltrative depth. Two signs of the neighboring infiltrative depth groups were compared and analyzed, so as the relativity between two signs and tumor infiltrative depth. Results Among all 123 patients, 7 were Tis, 6 were T1, 14 were T2a, 16 were T2b, 75 were T3 (including 22 infiltrate to chorion and 53 infiltrate through chorion) and 5 were T4. According to the pathologic infiltrative depth, the patients were grouped into GroupⅠ: Tis+T1;GroupⅡ: T2a;Group Ⅲ: T2b;Group Ⅳ: T3a;Group Ⅴ: T3b+T4. Significant difference of the incidence of rigid wall was found between GroupⅠand Ⅱ (P=0.013), while of outer coarse between Group Ⅱ and Ⅲ (P=0.004). Coefficient correlation of rigid wall, outer coarse and the infiltrative depth of the tumor were detected (r=0.673, r=0.528, respectively, both P＜0.001), also between the two signs (r=0.725, P＜0.001). To predict the tumor of and above T1 with rigid wall and tumor of and above T3a with outer coarse, the sensitivity, specificity and accuracy was 92.30% and 79.31%, 89.09% and 69.44%, 89.43% and 76.42%, respectively. Conclusion The sign of rigid wall is valuable to distinguish the pathological changes in the tumor of and above T1, while outer coarse is better to distinguish the pathological changes of and above T2a, but not good at distinguishing tumors of T2b and T3 or above. Rigid wall and outer coarse are both in positive correlation with the infiltrative depth of the tumor, and each has different values. Combination of the two signs may be helpful to raise the accuracy for pre-operation staging of colorectal carcinoma.

Objective To observe imaging characteristics and changes of vivo two-dimension multi-voxel proton magnetic resonance spectroscopy (~1H-MRS) in the rabbit models of VX2 hepatic carcinoma after high intensity focused ultrasound (HIFU) treatment. Methods VX2 hepatic carcinoma models were established in 20 New Zealand rabbits. Routine MR and 2-dimentional ~1H-MRS scanning were performed before and after HIFU treatment. The central regions of interest (ROI) of the VX2 tumor, tumor border and paratumor normal liver tissues were selected. The Cho/Cr and Lip/Cr of the same ROI before and after HIFU treatment were compared. Results Total 28 satisfied spectrogram diagram of ~1H-MRS were brought into statistical analysis. Of all the spectra, 6 metabolite peaks were detected as lipids (Lip), glutamine and glutamate complex (Glx), choline (Cho), lactate (Lac) and creatine (Cr). Cho and Lac peak in tumor center and tumor border regions after HIFU treatment were higher than those before HIFU treatment. Lip peak was lower than before, and major metabolites of paratumor normal liver tissues did not changed significantly. Statistical differences of Cho/Cr and Lipid/Cr of tumor center and border region were found between before and after HIFU treatment (P＜0.05). Conclusion Two-dimension multi-voxel ~1H-MRS can reflect major changes in the level of metabolites of different ROI for hepatic VX2 carcinoma after HIFU treatment.
