Which imaging modality is commonly used initially to evaluate suspected endometrial cancer by assessing the endometrial stripe?

• A. Transvaginal ultrasound
• B. CT abdomen
• C. Mammography
• D. Brain MRI

Answer: (A)

Evaluating suspected endometrial cancer starts with imaging that can quantify the thickness of the endometrium. Transvaginal ultrasound uses a probe placed in the vagina to obtain high-resolution images of the uterus, allowing precise measurement of the endometrial stripe. In patients with abnormal uterine bleeding, especially postmenopausal bleeding, the thickness of this lining guides urgency and next steps; a thicker endometrium raises concern for pathology and often leads to obtaining tissue for histology. This approach is preferred because it is noninvasive, readily available, cost-effective, and does not involve radiation. Other imaging like CT abdomen doesn’t provide as clear detail of the endometrial lining and is used more for staging or evaluating metastasis, while mammography and brain MRI are not relevant for assessing the uterus or endometrial cancer.
