2021年8月25日 · The International Ovarian Tumor Analysis (IOTA) group ultrasound rules for ovarian masses are a simple set of ultrasound findings that classify ovarian masses into benign, malignant or inconclusive masses.

2019年2月16日 · In this chapter, we will review a few normal findings specific to the ovary, discuss sonographic features of benign and malignant ovarian masses, present an approach to assessing indeterminate ovarian masses, and review pitfalls in evaluation of the ovary.

For characterization of ovarian masses, ultrasound is often the first-line method of choice, especially for distinguishing cystic from complex cystic-solid and solid lesions. CT is useful for the N- and M-staging of proven malignant lesions. For complex lesions, primary evaluation with ultrasound is often followed by further evaluation with MRI.

A small percentage (8–10%) of ovarian masses are difficult to classify as malignant or benign. For these, the use of 3D ultrasound 44–46 or contrast media 47–49 has been proposed but with limited additional value. MRI could play a role in classifying …

Ultrasonography (US) is the primary imaging modality for identifying and characterizing ovarian masses. US is a relatively simple and noninvasive diagnostic method that provides clinicians with useful information relevant for determining the optimal management strategy for a given patient.

In this narrative review we aim to describe the typical morphological features seen on ultrasound of different adnexal masses and illustrate these by showing representative ultrasound images. Keywords: ovarian cancer, ovarian neoplasm, ovary, pattern recognition, ultrasonography

2020年9月17日 · Ultrasound assessment of the morphological and vascular features of a mass has been shown to be highly effective for predicting whether a mass is benign or malignant. Accurate characterization of adnexal masses is essential for optimal patient management.

2020年5月30日 · Malignant ovarian lesions can have typical sonographic features, and thus ultrasound is the imaging of choice for initial evaluation of suspected ovarian neoplasm. The features of malignant ovarian neoplasm on ultrasonography include: 1. erich lang. Radiology of the Female Pelvic Organs. Springer Science & Business Media. (2012) ISBN:3642602606.

2019年11月8日 · Pelvic sonography, including transvaginal scanning, is the preferred initial imaging modality for evaluation of a suspected ovarian or other adnexal mass. Its high sensitivity and specificity for ovarian malignancy, lack of ionizing radiation, relatively low cost, and wide availability make it an ideal method for evaluation of the ovary.

Investigation for an ovarian mass includes both transvaginal and transabdominal ultrasound. Simple, anechoic cysts <5 cm in premenopausal women are likely to be benign and do not require further follow-up.
