RESUMO
During the past 10 years, performing real-time molecular imaging with positron emission tomography (PET) in combination with computed tomography (CT) during interventional procedures has undergone rapid development. Keeping in mind the interest of the nuclear medicine readers, an update is provided of the current workflows using real-time PET/CT in percutaneous biopsies and tumor ablations. The clinical utility of PET/CT guided biopsies in cancer patients with lung, liver, lymphoma, and bone tumors are reviewed. Several technological developments, including the introduction of new PET tracers and robotic arms as well as opportunities provided through acquiring radioactive biopsy specimens are briefly reviewed.

PURPOSE OF REVIEW: This review focuses on novel imaging techniques used for guiding urologic procedures that are likely to provide additional opportunities to physicians in the years to come. RECENT FINDINGS: In the past, most image-guided urologic procedures have utilized two-dimensional x-ray images. This review will discuss the use of a variety of new and more sophisticated image-guiding tools such as rotational fluoroscopy, intraoperative ultrasound, endoscopic ultrasound, ultrasound elastography, real-time computed tomography, magnetic resonance fluoroscopy, and molecular imaging. SUMMARY: Technological breakthroughs in imaging have led to the development of minimally invasive techniques in urologic care. Application of these new techniques brings together the complementary disciplines of endourology and interventional radiology to optimize treatments and outcomes for urologic disease.
