The clinical value of dynamic contrast-enhanced MRI in differential diagnosis of malignant and benign ovarian lesions.

Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) is widely used in preoperative diagnosis of various tumors. We investigated the clinical value of DCE-MRI in differential diagnosis of malignant and benign ovarian lesions. The study involved 48 subjects with surgical pathology-confirmed ovarian tumors with solid components.

[Imaging features of duplication of the internal auditory canal].

Objective: To explore multiple slices computed tomography (MSCT) and magnetic resonance imaging (MRI) features of duplication of the internal auditory canal (DIAC) in order to improve the accuracy of diagnosis.

Methods: Four cases (5 ears) were analyzed and the related documents were reviewed retrospectively. MSCT was performed on all cases, and two cases had MRI scanning at the same time.
