Abstract：Objective To investigate the diagnostic efficacy of contrast-enhanced ultrasound and MRI in the clinical features and
prognosis of non-mass ductal carcinoma in situ (DCIS). Methods A total of 100 patients with non-mass DCIS who underwent
contrast-enhanced ultrasound and MRI in our hospital From January 2021 to November 2023 were selected. The diagnostic accuracy
of contrast-enhanced ultrasound and MRI, and the relationship between their scores and clinical features and prognosis were
observed and recorded. Results Among the 100 patients, 83 cases of non-mass DCIS were detected by contrast-enhanced ultrasound,
with an accuracy of 83.00% (83/100); 86 cases were detected by MRI, with an accuracy of 86.00% (86/100); 93 cases were detected
by contrast-enhanced ultrasound combined with MRI, with an accuracy of 93% (93/100). There were significant differences in the
ultrasonographic evaluation of pathological type, lymph node metastasis, histological grade and nuclear grade among the groups of
non-mass DCIS patients (P<0.05). There were significant differences in MRI evaluation of pathological type, lymph node metastasis,
histological grade and nuclear grade among the groups of non-mass DCIS patients (P<0.05). Compared with the good prognosis
group, the contrast-enhanced ultrasound scores and MRI scores of the poor prognosis group were significantly increased, with
statistical difference between the groups (P<0.05). The area under curve of non-mass DCIS detected by contrast-enhanced ultrasound
was 0.790, that of MRI was 0.834, and that of the combination was 0.919. Conclusion Contrast-enhanced ultrasound and MRI have
diagnostic value for the clinical features and prognosis of non-mass DCIS, and the combined diagnostic value is higher, and can be
used for the differential diagnosis and prognosis evaluation of the clinical features of non-mass DCIS.
