17 wrz 2023 · Ultrasound is usually the first imaging modality for assessment of ovarian lesions. Imaging features of simple ovarian cysts: anechoic. intraovarian or exophytic. imperceptible wall. posterior acoustic enhancement: may not be as obvious with harmonic or compound imaging. visible far wall.
On ultrasound hemorrhagic ovarian cyst presents as an unilocular thin-walled cyst with fibrin-strands or low-level echoes and good through transmission. On MRI hemorrhagic cysts are bright on pre-contrast T1-FatSat, and dark on T2.
15 maj 2011 · In this article we will focus on specific features of ovarian cysts that are helpful in making a differential diagnosis. We will present a roadmap for the diagnostic work-up and management of ovarian cystic masses, based on ultrasound and MRI findings.
29 mar 2024 · According to a consensus statement 6, yearly follow-up is suggested for cysts 5-7 cm, and large cysts (>7 cm) should ideally be assessed with MRI to exclude any subtle worrisome features, as it may be difficult to visualize these entirely with ultrasound.
23 gru 2020 · Ultrasound image shows avascular cyst in right ovary has reticular pattern (arrow) consistent with hemorrhagic cyst. Because it is smaller than 10 cm, cyst is consistent with Ovarian-Adnexal Reporting and Data System (O-RADS) category 2 lesion.
4 maj 2021 · This two-part review describes a stepwise approach to evaluating and characterizing adnexal masses in non-pregnant patients. Here in part 1, we will review the utilization of ultrasound in this endeavor. In part 2, we will review the use of MRI.
The primary imaging modality for evaluation of ovarian cystic lesions is pelvic ultrasonography. Most ovarian cysts are benign and demonstrate typical sonographic features that support benignity. However, some ovarian cystic lesions have indeterminate imaging features, and the approach to management varies.
