PURPOSE MR assessments of ovarian cystic lesions are usually based on morphological features, signal intensities and enhancement with contrast media. This study was performed to evaluate the usefulness of the steady-state free precession (SSFP) diffusion imaging of cystic ovarian lesions for analyzing cystic contents. MATERIALS AND METHODS Sixty-one ovarian cystic lesions in 37 patients were ...

Disease of the ovary are a significant cause of morbidity and mortality amongst Zimbabwean women. There is however, scanty data regarding the types and extent of these conditions. A retrospective review of histologically diagnosed ovarian disease was carried out in order to determine the types, prevalence and age distribution of ovarian pathology seen in Harare over a 22 month period. Pathologi...

OBJECTIVE We propose a Magnetic Resonance Imaging (MRI) guided approach to differential diagnosis of ovarian tumours based on morphological appearance. BACKGROUND Characterization of ovarian lesions is of great importance in order to plan adequate therapeutic procedures, and may influence patient's management. Optimal assessment of adnexal masses requires a multidisciplinary approach, based o...

Ovaries are paired structures with an embryological, anatomic and functional complexity. Changes in their volume can be observed at ovulation, pregnancy and after menopause. Ovaries are normally resistant to diseases, but still ovary can be seat of more number of neoplastic lesions of benign and malignant. They may be primary or secondary, large or small, solid or cystic and also of mixed patte...

Ovarian cancer has a high mortality rate largely due to the limited number of ovarian carcinomas detected at an early stage. Understanding the molecular changes occurring during the progression of ovarian carcinoma would aid in the development of therapies that may inhibit or target metastasis. Primary and metastatic lesions from 54 and 40 patients with advanced ovarian carcinoma, respectively ...

Problem statement: Elastography is developed as a quantitative approach to imaging linear elastic properties of tissues to detect suspicious tumors. We propose an automatic feature extraction method in ultrasound elastography and echography for characterization of breast lesions. Approach: The proposed algorithm was tested on 40 pairs of biopsy proven ultrasound elastography and echography imag...

Methods Using texture analysis, we analysed 104 lesions in 104 patients suspected for lung cancer with a positive CT correlate. The analysis was performed using TexRAD (developed by TexRAD Ltd. UK). Histology was our reference standard. Malignancy was present in 92 lesions. CTTA comprised a filtration-histogram technique where filtration extracted and enhanced features of different sizes (fine,...
