Sonography

This observational study will evaluate how well an ultrasound scoring system called O-RADS can distinguish between benign (non-cancerous) and malignant (cancerous) ovarian masses in women aged 18 to 70 years. Women who are found to have an ovarian cyst or mass during routine pelvic or transabdominal ultrasound at Women's Health Hospital will be invited to participate and will receive standard care, including detailed transvaginal ultrasound, MRI when indicated, surgery if needed, and histopathology (tissue examination). The main question is how accurately O-RADS ultrasound categories predict the final tissue diagnosis; the study will also look at how ultrasound findings relate to MRI results in characterizing ovarian masses.

The investigators plan to do serial sonographic examinations of the gastric antrum (quantity, quality) to estimate the gastric emptying time and dependant factors after traumatic injurys.

The aim of this study is to evaluate the prevalence of synovitis in adult patients with haemophilia A.
