Transvaginal ultrasound is the preferred imaging technique for evaluating ovarian cysts due to several key factors. Firstly, this method allows for a detailed assessment of the ovaries in a manner that is less invasive and provides real-time imaging. With transvaginal ultrasound, the transducer is positioned close to the pelvic organs, allowing for clearer visualization of the ovaries and any cystic formations.

Additionally, transvaginal ultrasound is effective in differentiating between simple and complex cysts, which is crucial for determining the appropriate management. Simple cysts, which are typically benign, appear anechoic on ultrasound, while complex cysts may indicate the need for further investigation due to the potential for malignancy.

Other imaging modalities, although useful in some contexts, do not offer the same advantages for initial evaluation of ovarian cysts. X-rays are limited in their capability to visualize soft tissue structures such as ovaries and cysts. Computed tomography, while providing good detail, involves radiation exposure and is not as sensitive for small cysts. Magnetic resonance imaging might be used in specific cases for further characterization after ultrasound, but it is not the first-line technique for ovarian cyst evaluation. Hence, transvaginal ultrasound remains the primary choice for
