Comparison of diagnostic value of multi‑slice spiral CT and MRI for different pathological stages of prostate cancer

Abstract

Diagnostic value of magnetic resonance imaging (MRI) and multi-slice spiral CT (MSCT) for different pathological stages of prostate cancer was compared. A total of 112 patients with prostate cancer who underwent surgical pathology in The Affiliated Yantai Yuhuangding Hospital of Qingdao University from February 2014 to January 2016 were enrolled as prostate cancer group, and another 100 patients who received physical health examinations during the same period as the normal group. MSCT and MRI scanning were performed on patients in both groups to analyze their diagnostic value for stages A/B and C/D of prostate cancer. Based on the apparent diffusion coefficient (ADC) value generated by the diffusion-weighted imaging (DWI) in MRI, there was a significant difference in the ADC value between different stages of prostate cancer (P<0.05); the pathological stage was negatively correlated with the ADC value (r=−0.7629, P<0.05), and the higher the stage was, the lower the ADC value was. The sensitivity was significantly higher in the MRI group than that in the MSCT group (92.0 vs. 79.5%, P<0.05), and the specificity was significantly higher in the MRI group than that in the MSCT group (90.0 vs. 70.0%, P<0.05). In the diagnosis of stage A and B of prostate cancer, the diagnostic coincidence rate was 86.7% in the MRI group, and 57.8% in the MSCT group (P<0.05); the misdiagnosis rate and missed diagnosis rate were significantly lower in the MRI group than those in the MSCT group (P<0.05). The accuracy of MRI is higher than that of MSCT in the diagnosis of early prostate cancer. Both MRI and MSCT can accurately detect stages C and D of prostate cancer, but the ADC value in MRI has great clinical significance for judging the risk of the tumor. Therefore, MRI is more valuable than MSCT in the diagnosis of patients with different pathological stages of prostate cancer.

Multi-Slice Spiral Computed Tomography Image Features under Hybrid Iterative Reconstruction Algorithm in Staging Diagnosis of Bladder Cancer

“…The ADC value in MRI is of great clinical significance in determining the risk of tumor. The conclusion was that MRI was more valuable than MSCT in the diagnosis of prostate cancer at different stages [ 24 ]. There were two methods utilized to diagnose peritoneal metastases from primary ovarian cancer, and the results also indicated that MRI was more accurate in the diagnosis of peritoneal metastasis in ovarian cancer patients compared with multi-slice spiral CT [ 25 ].…”

Diagnostic Value of Multislice Spiral CT Cardiothoracic Combined with Angiography in Acute Chest Pain

“…It provides a cost-effective modality for patients presenting to the emergency department with acute chest pain [21]. e test is able to make a diagnosis of noncoronary origin, which accounts for approximately the proportion of patients with acute chest pain in the emergency department, and it can avoid additional tests for the diagnosis of cardiac disease in patients who do not experience serious side effects during days of follow-up [22][23][24][25]. Multirow spiral is considered to have the potential to improve the diagnosis of acute chest pain in patients with low to moderate risk factors [26].…”

Image and Diagnosis Analysis of Multi-Slice Spiral CT and Chest X-Ray of Neonatal Pneumonia

“…2) External issues This type of incomplete projection data is caused by the inability to collect all projection data passing through a specific part of the detection area. This situation mainly occurs when there is an "opaque" substance in the detected radiation of the test object [18][19]. It can be derived from the Cormack inversion formula and uniquely determines the solution to the external problem.…”
