Objective: To review MSCT imaging features of 15 cases of basal cell tumor in parotid gland and explore its diagnostic value. Methods: Fifteen patients with pathologically confirmed basal cell tumor underwent preoperative MSCT plain-scan and dual-phase contrast scan. The change of CT value and enhancement patterns in the tumors were assessed. Quantitative analysis was performed to determine CT value changes of the tumors in different enhanced-phases as compared with the plain-scan. Compare these imaging features of basal cell tumor with those of other common benign tumors: pleomorphic adenomas and adenolymphomas. Analysis of variance was used for the statistical analysis. Results: Basal cell tumors showed isodense nodule with significant cystic area on CT plain-scan. At dual-phase scan, basal cell tumors showed a pattern of persistent strong enhancement with characteristic cystic areas. At arterial phase, the increase of CT value was the highest for basal cell tumors, which had statistical difference from pleomorphic adenoma(P<0.01). At venous phase, the increase of CT value was statistically different between basal cell tumor and the other two histopathologic types(P<0.05). Conclusion: Basal cell tumors showed hetergeneous isodense nodule on CT plain-scan, which showed a pattern of persistent strong enhancement with characteristic cystic areas. The CT features of basal cell tumors were different from those of the other two bengin tumors.

DOI:
Objective: To investigate the signs of renal cell carcinoma(RCC), and improve the imaging diagnosis of renal malignant neoplasm with multi-phase dynamic enhancement CT scanning. Materials and Methods: The multi-phase contrast enhanced helical CT scan data of 72 patients with surgical-pathologically proved renal malignant neoplasm were analyzed retrospectively. Fifty-seven cases of RCC, confirmed by pathological techniques, according to WHO classification, these included 38 clear cell carcinomas, 10 papillary, 8 chromophobe and 1 spindle cell RCC, were analyzed. Enhancement degrees and patterns in unenhanced, corticomedullary, nephrographic phase and excretory phase were compared. Results: CT attenuation on unenhanced scan was not statistically different. CT attenuation of clear cell carcinoma was higher than that of papillary and chromophobe RCC in corticomedullary, nephrographic and excretory phase(P value is 0.01, 0.01 and 0.03 respectively), while that of papillary and chromophobe RCC was not statistically different in all three phases. Homogeneous and heterogeneous enhancement was most commonly seen in chromophobe RCC and clear cell carcinoma. Conclusion: Dynamic enhanced CT scan was effective for differentiating clear cell carcinoma from non-clear cell carcinoma, and was useful in differentiating RCC. It could be used in formulating therapeutic plan preoperatively.

DOI:
Objective: To study the relationship between the CT manifestation of the TN-staging and the expressions of p53 protein in thoracic esophageal carcinoma. Methods: p53 protein expressions in esophageal carcinoma and its relationship with the TN-staging by CT were analyzed by means of SP immunohistochemical technique and CT scanning in 66 patients with esophageal carcinoma proved by pathology. Results: There were 3 cases staged as T1, 10 cases as T2, 41 cases as T3, and 12 cases as T4 by CT. Twenty-one cases were detected to have lymph nodes metastases. The positive-expression rate of p53 protein was 62.12%(41/66). The positive-expression rate of p53 protein in T4-stage was remarkably higher than that in T1~2 and T3-stage(χ2=3.412, P＜0.05, and χ2=3.381, P＜0.05). The positive-expression rate of p53 protein in cases with and without lymph nodes metastasis was 80.95%(17/21) and 37.78%(17/45) respectively, their difference was statistically significant(χ2=10.686, P=0.001). The high expression rate of p53 protein in group T1~2, T3 and T4 was 23.08%(3/13), 46.34%(19/41), 66.67%(8/12) respectively. The expression intensity of p53 protein was increasing in accordance with the rise of T-staging(rs=0.270, P=0.028). The positive-expression rate of p53 protein in cases with lymph nodes metastases(short axis diameter≤2cm) was 84.62%(11/13), in mediastinal lymph nodes metastases(short axis diameter＞2cm) was 75.00%(6/8). Their difference was not statistically significant(P=0.289). Conclusion: The high expressions of p53 protein were correlated to CT TN-staging. The expression intensity of p53 protein is increasing in accordance with the rise of T-staging. There was no correlation between the size of lymph nodes metastases and the expressions of p53 protein.

DOI:
Objective: To study the increase and decrease of MR signal in the functional cortical regions related to the vestibular vertigo with caloric stimulation, 0℃ water, using blood-oxygen level dependent functional MRI(BOLD-fMRI) technique. Materials and Methods: Twenty right-handed human volunteers, 12 males and 8 females, age from 25 to 39 years old, had nothing wrong with the hearing ability and the cavity of the middle ear after the otoscopic examination, the pure-tone audiometry and the tympanometry tests. They were all examined with a recording electronystagmograph before the fMRI scan to confirm that the caloric stimulus actually induced vestibular vertigo and nystagmus. During the electronystagmograph test, 15ml ice water(0℃) was injected into the right ear of each volunteer within 15s with the subject’s eyes open. The functional images of brain were acquired with a 1.5T Signa Infinity Twin+Excite MR system of GE Co. All the subjects were blindfolded with eyes open in a dark circumstance. All data were analyzed on single-subject level and group level using SPM 99. Result: Several cortical and subcortical regions were activated and deactivated. The activated regions included: the supplementary motor area, paracentral lobule, left precuneus lobe, left posterior insula, left MT/MST complex, the cingulum gyrus, left occipital lobe(BA19) and left cerebellum. The deactivated regions included: bilateral superior and middle frontal gyri, right precentral gyrus(BA2/3), left precuneus lobe, right MT/MST. Conclusion: Cold water stimulation at 0℃ in fMRI confirms a widespread cortical network involved in vestibular signal processing.

DOI:
Objective: To analyze the clinical and imaging features of gastrointestinal stromal tumors(GIST) and explore the imaging value in diagnosing the disease. Materials and Methods: The clinical and imaging data of 20 patients with GIST proved by operation and pathology were analyzed. Results: Tumors located in stomach 3 cases, in small bowel 11 cases, in colorectum 1 case and in extra gastrointestinal sites 4 cases. Immunohistochemical study diagnosed the GISTs as benign in 1 case, intermediate in 7 cases and malignant in 12 cases. The common symptoms were gastrointestinal tract bleeding(5/20), vague abdominal discomfort and abdominal pain(13/20), abdominal tumors(6/20) and abnormal bowel movements(3/20). The main imaging appearances included predominating exophytic growth, necrosis and liquefaction of tumors. On enhanced CT scan, the tumor enhanced moderately. Mass border is clear or unclear and metastases to local lymph nodes is uncommon, but it is easy to metastase to liver or seeding in abdominal cavity. Conclusion: The imaging features of GIST have some characteristics. CT, MRI examination have high value in detecting its location, evaluating its characteristics and treatment.

DOI:
Objective: To study the CT features of extra-pancreatic phlegmon in acute pancreatitis(AP) and the anatomic-pathological bases of its distribution. Materials and Methods: The CT findings of 126 cases of AP proved by operation or clinical treatment were retrospectively analyzed. The CT features of the phlegmon out side of the organ and the anatomic-pathological bases of its distribution were studied. Results: The CT findings of phlegmon appeared irregular soft tissue mass with CT value within 5~30HU, the marginal zone of the phlegmon appeared low-grade enhancement on enhanced scan. The distribution of phlegmon in 259 lesions more commonly appeared in lesser omental bursa(93 times), left anterior pararenal-space(69 times), right paracolonic groove(26 times) and left paracolonic groove(21 times), others including right anterior pararenal-space(12 times), pelvic cavity(11 times), posterior pararenal space, perirenal space and left suprahepatic space(5 times) respectively, left subhepatic space(4 times), right suprahepatic space, left mesentery sinus and thorax(2 times) respectively, right mesentery sinus and pericardiac 1 time respectively. Multiple lesions appeared in 67 cases. Conclusions: The CT findings of phlegmon out of the organ in AP were characteristic. The distribution of the phlegmon depended on the anatomic bases of the abdomen, but some compartment may be involved due to movement of the fluid and the devastating of the phlegmon.

ZHANG Xian;YAN Zhi-han;YU Zhi-kang;BAI Guang-hui;MAO Chuan-wan
DOI:
Objective: To approach the characteristics of dynamic contrast-enhanced MR imaging in cervical cancer. To provide reference to contrast-enhanced phase choice in cervical cancer. Methods: Twenty-five cases with pathologically proved cervical cancer were served as study group, 4 cases with cervical leiomyoma and 10 volunteers as control group. Plain scan and dynamic contrast-enhanced MR scanning were given to the patients in the study as well as to the individuals in the control group. For imaging data analysis, ROI was selected and time-intensity curves(TIC) were derived from dynamic contrast-enhanced MR imaging of ROI, calculate ROI enhanced rate(E)＝(the post contrast-enhanced signal intensity-the precontrast-enhanced signal intensity)×100%/the precontrast-enhanced signal intensity. On statistics, we compared the differences of enhanced rate respectively at different time, 16s, 32s, 48s, 64s, 128s. The T-test was used, P<0.05 was considered statistically significant. TIC were divided into four types. Results: Almost all cervical cancer showed marked contrast-enhanced appearance in the early period(0~32s). There were significant difference in early enhanced rate between cervical cancer, normal stroma of cervix and leiomyoma(P<0.05), but there were no significant difference on enhanced rate in the intermediate and late phase(P>0.05). In 25 cases with cervical cancer, 22 cases had type Ⅰ curve, 3 cases had type Ⅱ curve. In the control group, almost belong to type Ⅲ and type Ⅳ curve. Conclusion: Dynamic contrast-enhanced MR imaging can reflect the blood supply of the tumor, to emphasize signal change and enhanced rate in the earlier period(0~32s). Dynamic contrast enhanced study is useful to make diagnosis.
