Study on the Value of 3.0 T Magnetic Resonance Whole-body Background Signal Suppression Diffusion Weighted Imaging in the Diagnosis of Lymphoma
Objective To observe the efficacy of 3.0 T magnetic resonance diffusion weighted imaging with background suppression(DWIBS)in the diagnosis of lymphoma patients,and to improve the detection rate of clinical lymphoma.Methods The baseline data of 100 patients with lymphoma admitted to hospital from January 2020 to December 2022 were retrospectively analyzed.All the patients in the group underwent intraoperative rapid pathological examination and 3.0 T magnetic resonance DWIBS.The intraoperative rapid pathological examination was used as the gold standard to analyze the diagnostic efficacy of 3.0 T magnetic resonance DWIBS.Results Pathological examination showed that 72 cases(72.00%)were intranodal lesions and 28 cases(28.00%)were extranodal lesions.Efficiency of diagnosis of intranodal lesions:positive detection rate was 69.00%,sensitivity was 90.28%,specificity was 85.71%,accuracy was 89.00%.Taking the intraoperative rapid pathological results as the gold standard,the consistency between 3.0 T magnetic resonance DWIBS and the gold standard K value=0.736(P<0.001).The efficiency of diagnosis of extranodal lesions:positive detection rate was 31.00%,sensitivity was 92.86%,specificity was 93.06%,accuracy was 93.00%,and the consistency between the extranodal lesions examined by 3.0 T magnetic resonance DWIBS and the gold standard K value=0.832(P<0.001).The total accuracy of this technique in diagnosing intranodal lesions and extranodal lesions of lymphoma was 75.00%and 75.00%,respectively.Conclusion 3.0 T magnetic resonance DWIBS can significantly improve the detection rate of lymphoma and its stages.For clinical patients with highly suspected lymphoma,3.0 T magnetic resonance DWIBS technology can be adopted to improve the detection rate of clinical lymphoma.
