Abstract

We aimed to evaluate the depth of myometrial invasion preoperatively with transvaginal
ultrasound, magnetic resonance imaging, and frozen section examination techniques in patients
diagnosed with endometrial cancer. Our study included 65 patients. Transvaginal ultrasound
and magnetic resonance imaging were performed in study patients in the preoperative period. Frozen
section examination was performed in all hysterectomy samples obtained from all study patients. Data
were analyzed with SPSS Statistics 22.0 program. The sensitivity of transvaginal ultrasound in determining
the depth of myometrial invasion was 88.64%, specificity 90.48%, positive predictive value
95.12%, and negative predictive value 79.17%. For magnetic resonance imaging, the sensitivity was
63.64%, specificity 95.24%, positive predictive value 96.55%, and negative predictive value 55.56%. In
addition to the frozen section examination, which is the gold standard in determining the myometrial
invasion depth, transvaginal ultrasound and magnetic resonance imaging have become commonly
used methods for this purpose in recent years. Ultrasound examination performed by an experienced
specialist is superior to magnetic resonance imaging as it is fast, inexpensive, and associated
with higher sensitivity.
