Objective: To compare and analyze the clinical diagnostic value of multi-slice spiral CT and enhanced MRI for primary liver cancer (PLC), and to summarize the imaging findings.  Methods: The research subjects in this article were 50 patients with PLC who were admitted to our hospital from 2017 April to 2018 September. After the patients were admitted, they were examined by multi-slice spiral CT and enhanced MRI scanning, and the pathological diagnosis results were followed up. Relevant information was reviewed and analyzed.  Results: The detection rate of multi-slice spiral CT was higher than that of MRI in the portal venous phase lesion detection. The difference was statistically significant (P<0.05). The detection rate of lesions in the arterial phase and delayed phase was not statistically significant (P>0.05); the diagnostic accuracy of multi-slice spiral CT was 85.96%, and the diagnostic accuracy of enhanced MRI scanning was 91.11%, which was not statistically significant (P>0.05). MRI scans showed the capsules of primary liver cancer better than CT, but the difference was not statistically significant (P>0.05).  Conclusion: In conclusion, both multi-slice spiral CT and enhanced MRI can be used for the effective diagnosis of primary liver cancer intrahepatic lesions. The diagnostic value of the two is equivalent, but enhanced MRI has a slightly higher diagnostic accuracy and can be used as the preferred method.

Aim: To explore the diagnostic value of spiral CT chest enhanced scan for adults with active pulmonary tuberculosis. Methods: The clinical data of 60 adult patients with active pulmonary tuberculosis who were treated in our hospital from January 2018 to November 2019 were retrospectively analyzed. All patients underwent conventional chest radiography and spiral CT chest enhanced scan. The number of tuberculosis diagnosis, the detection rate of special site lesions, and the detection rate of active pulmonary tuberculosis signs by the two methods were compared. Results: In 60 patients, the pathological results confirmed the existence of 75 tuberculosis lesions. The detection rate of spiral CT was 98.67%, which was not statistically significant compared with the detection rate of 92.00% (P>0.05) in the conventional chest X-ray. The detection rate of spiral CT enhanced scans for tuberculosis lesions in special sites was 100.00%, which was significantly higher than that of conventional chest X-ray of 7.69%, and the accuracy rate of active pulmonary tuberculosis signs was 98.85% higher than that of conventional chest X-ray of 79.31%. P<0.05). The difference was statistically significant (P<0.05). Conclusion: Spiral CT chest enhanced scan can not only find special tuberculosis lesions that cannot be detected by conventional chest radiography, but also accurately determine active pulmonary tuberculosis in adults, which is of high diagnostic value.

In order to study the diagnosis of computed tomography (CT) image-assisted pulmonary tuberculosis patients, patients who are diagnosed as tuberculosis in Wuhan No. 6 Hospital Affiliated to Jianghan University are selected as a research object, and multi-slice spiral CT and routine X-ray examination are performed. By analyzing and comparing multi-slice spiral CT and routine X-ray examination, the diagnostic value of tuberculosis is evaluated and the detection rate of lesions in the lung and clinical classification of tuberculosis are also evaluated (including the anterior segment of the upper lobe, the posterior segment of the superior lobe, the dorsal segment of the lower lobe, the basal segment of the lower lobe, and concealment). The results show that compared with conventional X-ray examination, the sensitivity and accuracy of multi-slice spiral CT examination for diagnosis of pulmonary tuberculosis are higher, and the difference is statistically significant. In the upper part of the upper lobe, the posterior part of the upper lobe, the lower part of the lower lobe, and the tuberculosis lesions in the basal segment and hidden part of the lower lobe, the detection rate of multi-slice spiral CT examination is significantly higher than the X-ray examination, and the difference is statistically significant. In the diagnosis of tuberculosis classification, the misdiagnosis rate of multi-slice spiral CT examination is significantly lower than the conventional X-ray examination, and the difference is statistically significant. Therefore, CT images have important reference value in the diagnosis of tuberculosis, the examination of lesions, and the clinical classification of tuberculosis. Although there are still some shortcomings in the research process, it still provides some basis and ideas for more precise research.

Abstract Purpose：In this study, the aim was to assess the imaging features and radiomics of microvascular infiltration (MVI) of primary liver cancer (PLC) under the control of a seven-point pathological sampling method.Methods: The data of 37 patients with PLC who underwent surgical resection in our hospital from October 2018 to September 2019 were retrospectively collected. Postoperative pathological specimens were collected using a seven-point sampling method to determine the presence of MVI. Preoperative CT and MRI scans were performed to characterize the tumors. Findings from the imaging studies were imported into the radiomics platform, and 70% and 30% of the data were randomly assigned to the training and validation sets, respectively. Lastly, support vector machine (SVM) classifiers were used to classify liver lesions into their respective pathological types.Results: Differences in tumor morphology and satellite lesions were statistically significant between the MVI positive and MVI negative groups on CT images. On MRI, there were statistically significant differences between the MVI positive and MVI negative groups in peripheral enhancement of the arterial phase (AP) and peripheral low signal in the hepatobiliary phase (HBP). In the radiomics analysis, the imaging features extracted from the AP had strong predictive power in both groups (CT and MRI). For the phase images, 15 and 12 valuable features from CT and MRI were selected to develop the radiomics signature, respectively. The AUCs of the training set were 0.965 (sensitivity: 0.979; specificity: 0.931; precision: 0.939) and 0.962 (sensitivity: 0.963; specificity: 0.897; precision: 0.923) , the validation set were 0.842 (sensitivity: 0.967; specificity: 0.733; precision: 0.714) and 0.769 (sensitivity: 0.846; specificity: 0.727; precision: 0.727). The PVP also performed well on CT (AUC: 0.851/0.891) and MRI (AUC: 0.886/0.846). The predictive power was not enhanced by combining the features of multi-phase images.Conclusions: This was a controlled study on preoperative CT and MRI imaging and radiomics based on a seven-point pathological sampling method can avoid false-negative results caused by traditional pathological sampling. The imaging analysis results obtained and the radiomics prediction model established in this study may be more accurate than conventional models.

BACKGROUND: HCC is the most frequent primary liver cancer entity. Major risk factors comprise chronic HBC and HCV infections, ALD or NAFLD. Apart from the anamnesis, the clinical examination and serologic analysis, an essential part of the diagnostic HCC work-up is due to imaging findings from sonography, CT or MRI scans. HCC lesions feature a distinct vascularization pattern: hyperenhancement during early arterial and hypoenhancement/wash-out during portal venous or delayed phases. CEUS facilitates dynamic assessment of microperfusion patterns of suspicious liver lesions. PURPOSE: The purpose of the present retrospective single-center study was to determine the diagnostic value of CEUS for assessing HCC by comparison with findings from MRI scans. MATERIALS AND METHODS: Between 2004-2018 292 patients with suspicious liver lesions underwent CEUS and MRI. All patients underwent native B-mode, Color Doppler and CEUS after given informed consent. The applied contrast agent was a second-generation blood pool agent (SonoVue®, Bracco, Milan, Italy). Every CEUS examination was performed and interpreted by a single experienced radiologist (EFSUMB Level 3). RESULTS: CEUS was performed on all included patients without occurrence of any adverse effects. CEUS showed a sensitivity of 96%, a specificity of 91%, a PPV of 95% and a NPV of 94% for analyzing HCC in comparison with MRI as the diagnostic gold standard. CONCLUSION: With a distinguished safety profile CEUS shows a high diagnostic accuracy in assessing HCC compared to corresponding results from MRI scans.

The use of dynamic enhanced magnetic resonance imaging technology can effectively explore the diagnosis and clinical application of hematological malignancies. This paper selected 60 patients with hematological malignancies from 2015 to 2019; all of whom were diagnosed with hematological malignancies, including 40 men and 20 women, aged between 40 and 77 years. The main clinical manifestations of the patient are hematological malignancies, fever, and other symptoms. We used Siemens 3.0T to perform MRI and dynamic enhanced MRI examinations on 30 patients with hematological tumors. The PACS system was used to collect and organize clinical data. All patients were pathologically confirmed and clinically diagnosed with hematological malignancies. Based on the clinical data of the patients, retrospective analysis and summary were conducted and the clinical manifestations of hematological malignancies were discussed. The results showed that the diagnostic accuracy of 30 cases of dynamic enhanced MRI was 100%, while the diagnostic accuracy of ordinary MRI was lower than that of dynamic enhanced MRI, P < 0.05 , and the difference was statistically significant. In addition, compared with dynamic enhanced MRI and MRI, P > 0.05 , the difference was not statistically significant. Therefore, the application of dynamic enhanced MRI in the diagnosis of hematological malignancies is valuable.
