ABSTRACT
Objective To analyze the clinical value of 1. 5T dynamic enhanced MRI in the differential diagnosis of prostate cancer. Methods A total of 298 patients with prostate disease admitted to Zhejiang Quhua Hospital from January 2017 to December 2017 were enrolled. All subjects underwent MRI(including T2WI,DWI, DCE),and the results of all subjects were observed. The pathological biopsy was used as the gold standard for diagnosis. The possibility of prostate cancer was evaluated. Results Among the 298 patients with prostate disease,there were 136 cases of prostate cancer,including 84 cases of peripheral prostate cancer,the detection rates of T2WI,DWI and DCE were all 100. 00％,52 cases of central gland prostate cancer,the detection rates of T2WI,DWI and DCE were 100. 00％,98. 08％,and 98. 08％,respectively. Among 298 patients with prostate disease,there were 162 cases of pre-existing adenitis,including 64 cases of peripheral prostatitis. The detection rates of T2WI,DWI and DCE were 98. 44％,100. 00％,96. 88％,respectively,98 cases of central glandular gland inflammation,the detection rates of T2WI,DWI,DCE were 97. 96％,100. 00％,98. 98％,respectively. Conclusion 1. 5T dynamic enhanced MRI can correctly detect prostate diseases,especially prostate cancer.
ABSTRACT
With the development of molecular imaging technology, incorporate multiple modes of medical imaging imaging techniques of SPECT/CT and PET/CT technology with a certain degree of development. But compared to SPECT/CT and PET/CT technologies, SPECT/CT far earlier than PET/CT technology to clinical applications, due to a variety of factors influence SPECT/CT far PET/CT clinical applications to grow faster. This article highlights the progress and problems of SPECT/CT technology.

Objective To discuss and analyze the CT appearances and differential diagnosis of pulmonary tuberculomas. Methods 40 cases of pulmonary tuberculomas proved by surgery and pathology were included in the study and compared to 40 cases of peripheral-type bronchogenic carcinomas, which were also surgico-pathologically proved. Results Tuberculomas were most found in the posterior segments of the lung and exhibited well-demarcated lesions of homogeneous density. Some lesions also possessed characteristics like rough spiculation, minute calcification within the lesion and marginal calcification. Thick-walled, thin-walled or stellate cavities were also found. On contrast enhanced scans, tuberculomas showed little or ring enhancement. In addition, satelite lesions or pleural thickening were often found near the tuberculomas. Hilar and mediastinal lymph-nodes were calcified but not enlarged. Anti-tuberbulosis therapy often resulted in little or even no absorption.Conclusion More accurate diagnosis of pulmonary tuberculomas could be made after careful analysis of all CT signs and the clinical data. CT-guided needle biopsy could be used when the dignosis could not be made clearly.
ABSTRACT
Objective To study the relationship between Epstein-Barr virus(EBV) and Hapatocellular carcinoma (HCC). Methods Polymerase chain reaction (PCR) and immunohistochemical staining were applied to detect EBV in paraffin tissue sections from 78 HCC patients. Results EBV DNA was detected in 22 patients (28 2%) by PCR. Immunohistochemical staining of EBV LMP1 revealed that the positive signals were mainly localized in the tumor cells. Conclusions These observations suggest that EBV may pay a role in the development of HCC.
