Scintigraphy (SPECT)

Scintigraphy or SPECT are imaging devices that use the detection of gamma rays emitted by the drug administered to the patient to produce functional images. In order to improve anatomical analysis, scintigraphy and SPECT are regularly combined with CT. The main organs explored are bone, thyroid, lung, kidney and brain. The search for cardiac ischaemia is also a scintigraphic indication. An exercise test is therefore coupled with the examination

PET/CT

PET/CT is an imaging device that combines positron emission tomography and a CT scanner to study the metabolic activity of tissues or the presence of certain cells (molecular receptors) in the body and to provide anatomical information in parallel.

In oncology, PET/CT is the most widely used technique for tumour diagnosis, pre-treatment assessment of extension, evaluation of response to treatment, tumour targeting for external irradiation or the search for recurrence and metastases. In addition to oncology, this technique is used for cardiological and neurological examinations and to search for inflammatory or infectious sites.

In cardiology, the search for ischaemia and myocardial viability can be assessed by PET/CT, both qualitatively and quantitatively. In neurology, we look for neurodegenerative diseases (such as Alzheimer's disease.
