To analyze the ultrasound characteristics, clinical management, and pregnancy outcomes of heterotopic intramural pregnancies (HIMPs) after embryo transfer. This was a retrospective observational study of women who were diagnosed with HIMPs. The ultrasound characteristics, clinical treatment, and pregnancy outcomes of patients with HIMPs were evaluated.

Microvascular imaging versus CEUS in the characterization of renal masses: preliminary experience in a tertiary care referral university hospital

Bertelli E, Vizzi M, Lattavo L et al.

Evaluation of the possible role of microvascular imaging (MI) for the detection of vascularization of renal lesions, while comparing it with contrast-enhanced ultrasound (CEUS). 137 patients (160 renal lesions, 64 solid and 96 cystic) were enrolled in this single-center, retrospective, observational study. For solid masses, both the intralesional and the peripheral vascularization was analyzed and quantified by MI and then compared to peak enhancement on CEUS. Regarding cystic lesions, we evaluated the presence or absence of vascularization within the cystic wall and/or septa. MI results were compared with CEUS findings using Pearson's Chi square test. An optimal size cut-off for renal lesions was determined with the Youden test.
