Differences in the Diagnosis and Treatment of Patients with Early-Stage Hepatocellular Liver Cancer by Multi-Row Spiral CTMDCT and Gd-EOB-DTPA-Enhanced MRI.

Objective: The assessment of liver cancer lesion characteristics mainly relies on multi-row spiral computed tomography (MDCT) and magnetic resonance imaging (MRI). MDCT suffers from a series of problems, such as low soft tissue contrast and large tumor boundary errors, which lead to its limited practical application value in liver cancer. In contrast, Gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid (Gd-EOB-DTPA)-enhanced MRI has better soft-tissue contrast than MDCT and increases the clarity of liver cancer lesions. To investigate the differences between MDCT and Gd-EOB-DTPA-enhanced MRI in managing patients with hepatocellular liver cancer. Methods: A total of 80 patients diagnosed with hepatocellular carcinoma of the liver, who received treatment at our hospital between September 2020 and September 2022, were included in this study. These patients were evenly divided into two groups: the observation group and the control group, with 40 cases in each. The aim of this study was to compare the differences in signal indices of hepatobiliary stage between the two groups in patients with hepatocellular carcinoma. Results: A total of 89 cancer nodules were detected in patients by MDCT, and 109 cancer nodules were detected in patients by Gd-EOB-DTPA-enhanced MRI. When the number of nodules detected by both imaging modalities was statistically analyzed, the differences in the number of hepatocellular carcinoma (HCC) nodules detected by MDCT and Gd-EOB-DTPA-enhanced MRI were statistically significant (P < .05). Further analysis of the data by single cancer nodule, multiple cancer nodules, and cancer nodule size showed that the difference between the two imaging modalities was statistically significant (P < .05) in the diagnosis of patients with a single liver cancer nodule or multiple liver cancer nodules (94.8% vs.81.3%). The difference in the comparison was statistically significant (P < .05). Conclusion: Gd-EOB-DTPA-enhanced MRI demonstrates superior diagnostic efficacy in detecting small hepatocellular carcinoma, offers improved staging capabilities for hepatocellular carcinoma, and provides more precise guidance for treatment planning.Consequently, Gd-EOB-DTPA-enhanced MRI exhibits exceptional diagnostic value and serves as a valuable tool for guiding treatment decisions in patients with hepatocellular carcinoma.

Diagnostic Accuracy of MRI in Knee Meniscus Tear and ACL Injury.

Objective: Knee injuries are very common and may lead to other secondary injuries if effective treatment is lacking. In addition to standardized physical examination, magnetic resonance imaging (MRI) is sometimes considered an aid in the diagnosis of knee trauma. In order to have a more accurate diagnosis of knee injuries, we compared MRI with arthroscopic findings in this study to evaluate the diagnostic accuracy of MRI for meniscal tears and anterior cruciate ligament injuries of the knee. Methods: One hundred and ten patients with suspected meniscal tears and anterior cruciate ligament injuries of the knee who were admitted to our hospital from June 2020 to June 2022 were selected as study subjects, and the clinical data of the patients were retrospectively analyzed. All patients underwent MRI for preoperative diagnosis, and the sensitivity, specificity, MRI findings, and confirmation of diagnosis were compared and analyzed, and the accuracy of MRI in diagnosing meniscal tears and ACL injuries of the knee was analyzed. Results: The mean ACL angle was (98.0 ± 5.4) in the MRI group and (118.0 ± 6.8) in the arthroscopic group, the difference between the two groups was statistically significant P < .05. The mean L/H value of the ACL was (2.12 ± 0.38) in the MRI group and (1.81 ± 0.19) in the arthroscopic group, which was statistically different between the two groups (P < .05). Among the patients, 68 meniscal injuries were found in the MRI examination, including 45 cases of knee meniscal tears and 23 cases of anterior cruciate ligament injuries. The sensitivity, specificity, positive and negative predictive values, agreement rate, kappa value, and Youden index of MRI in diagnosing meniscal tears and ACL injuries were all high. Conclusions: In terms of sensitivity and accuracy, MRI is an excellent imaging technique for the diagnosis of meniscal tears and anterior cruciate ligament injuries of the knee.
