Molecular imaging of breast cancer: present and future directions.

Medical imaging technologies have undergone explosive growth over the past few decades and now play a central role in clinical oncology. But the truly transformative power of imaging in the clinical management of cancer patients lies ahead. Today, imaging is at a crossroads, with molecularly targeted imaging agents expected to broadly expand the capabilities of conventional anatomical imaging methods.

[Seminoma and teratocarcinoma: synchronic unitesticular presentation as independent nodules with different histologies? Ultrasound characteristics].

Objective: To describe the ultrasound characteristics, vascularization pattern (colour Doppler ultrasound) and possible histogenesis of one case of synchronic untesticular seminoma and teratocarcinoma as independent tumor nodules, histologically different, in a 19-year-old patient with testicular mass for eight months.

Methods: Conventional ultrasound, colour Doppler ultrasound, and high resolution Doppler angiogram were performed, analyzing vascular flows. After resection of the tumor, macroscopic and histological sections were related with ultrasound images.
