Abstract:
Twenty-one patients with ovarian tumors are studied using transabdominal color Doppler, in order to predict malignancy, depending on the vascular pattern obtained. In the 4 ovarian cancers, the resistance index (RI) was below 0.70. In 16 benign tumors the RI was above 0.70. Only one benign tumor, (hemorrhagic thecaluteinic cyst) had a low resistance vascular pattern. The sensibility of the method was 100%, its specificity 94.1%, the positive predictive value 80% and the negative predictive value 100%.

Ultrasound I: Abdominal Ultrasonography
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
