Imagiologia Médica

The following general knowledge are recommended:
· Basic principles of nuclear and radiation physics;
· Dosimetry and Radiation Protection.

The teaching methodology comprises only theoretical classes, in which the concepts corresponding to the syllabus are presented orally. Examples and exercises are also given whenever appropriate.

Acquire general knowledge about the physical and instrumental principles of the main modalities of medical imaging, namely in the areas of: conventional X-Rays and CT, Nuclear Medicine, Ultrasound, and Magnetic Resonance Imaging.

1) Radiography
· Nature of X-Rays;
· X-Ray transmission;
· The X-Ray tube;
· X-Ray detection: analog and digital detectors, fluoroscopy.

2) Computerized Tomography (CT):
· Principles of CT;
· Introduction to image reconstruction;
· CT scanners components.

3) Nuclear medicine:
· Morphological imaging vs. functional imaging;
· Radioisotope production;
· Scintigraphy and SPECT;
· Positron emission tomography (PET): constitution of tomographs.

4) Ultrasound
· Sound waves;
· Reflection, transmission and attenuation of sound waves;
· Focusing;
· Ultrasound transducers;
· Principles of ultrasound;
· Presentation modes;
· Eco-Doppler.

5) Magnetic Resonance Imaging (MRI):
– Physical principles;
· Imagiological principles;
· Constitution of CT scanners.
