- Dual source/dual energy-renal applicationsPublication . Adubeiro, Nuno; Nogueira, Luísa; Guedes, Mónica; Pinho, ErnestoDevelopment of Dual Source Computed Tomography (Definition, Siemens Medical Solutions, Erlanger, Germany) allowed advances in temporal resolution, with the addition of a second X-ray source and an array of detectors to the TCM 64 slices. The ability to run exams on Dual Energy, allows greater differentiation of tissues, showing differences between closer attenuation coefficients. In terms of renal applications, the distinction of kidney stones and masses become one of the main advantages of the use of dual-energy technology. This article pretends to demonstrate operating principles of this equipment, as its main renal applications.
- Imaging for radiofrequency ablationPublication . Adubeiro, Nuno; Pereira, Daniel; Nogueira, Luísa; Pinho, ErnestoMany solid tumors have a poor response to systemic chemotherapy, local radiotherapy or surgical recession. They are responsible for premature morbidity and decreased patient survival. The radiofrequency ablation is an emerging technique, and is now becoming more widespread throughout the world because it is minimally invasive, image guided, which offers the possibility of an effective and less costly approach. The procedure can be performed percutaneously, guided by several imaging modalities as Ultrasound, Computed Tomography and Magnetic Resonance. This article pretends to demonstrate the state-of-the-art of this technique focusing in the technical aspects and application of radiofrequency ablation.
- Ressonância magnéticaPublication . Pinho, ErnestoA imagiologia desempenha um papel fulcral na avaliação do doente oncológico. O rápido e contínuo desenvolvimento tecnológico acentuaram esta simbiose. Atualmente, o diagnóstico, a decisão e o planeamento terapêutico, bem como o estadiamento estão altamente dependentes das tecnologias de imagem. Uma outra vertente muito importante onde a imagiologia dá é a investigação.
