Nuclear Medicine

  • Nuclear Medicine

The Nuclear Medicine is a modern medical specialty that uses "open radiation sources" for diagnostic and therapeutic purposes. The term "open sources" refers to substances labeled with radioisotopes that are administered intravenously or orally to the patient, in order to obtain information on the function and metabolism of the human body organs or for the treatment of certain diseases.

In general, the radioisotopes used in nuclear medicine decay emitting either gamma or beta radiation, or, in some cases, both. Radioisotopes emitting gamma radiation are preferable in diagnostic applications, whereas in therapeutic applications, beta emitters are used.

Diagnostic applications are divided in “IN VIVO” and “IN VITRO” applications (the latest referring in biological body fluids, e.g. blood, urine). The IN VIVO diagnostic applications, in their great percentage regard scintigrams, which are performed using gamma-camera.

Hygeia Hospital has 2 modern tomographic (i.e. with 360o rotation around the patient capability) Philips γ-cameras.

In specific:

a) Bright View γ-camera, with 2 heads of variable angle, which is able to acquire anterior and posterior or bilateral images simultaneously, reducing by half the examination time in comparison to the conventional single head γ-camera. Bright View also uses automatic tangential movement technology with body sensors that allow the γ-camera heads to move in minimal distance to the patient’s surface without contact . The tomographic capability allows performing of Single Photon Emission Tomography (SPECT). Tomographic imaging reveals information from the depth of the examined organs that is not possible to be received by the conventional planar imaging.

b) and Bright View XCT, which is a system of two gamma camera heads as provided above, with the addition of the revolutionary low emission X-ray “flat panel” technology. This device can provide anatomical information of the examined body region of the patient, in order to use it for the process of attenuation correction. In addition, the same images can be fused with the tomographic scintigraphy (SPECT) images, producing SPECT/CT images. Bright View XCT achieves superior image quality and reduces the data acquisition time in half, reducing the overall examination duration on patients’ benefit.

Both γ-cameras are connected to a superfast JetStream type computer network, with extremely sophisticated software and unlimited image processing capabilities. Hygeia’s Nuclear Medicine Department is Philips’ Reference Centre for the regions of Southern Europe and Middle East.

/ IN VITRO

The in vitro diagnostic applications (Radioimmunoassay-RIA and Immunoradiometric Assay-IRMA) constitute a significant part of HYGEIA Hospital's Nuclear Medicine Department activities. Equipped with the necessary technology, the in vitro department performs a series of tests for detecting hormones, medications, vitamins, allergies and many other substances in the blood, urine and other biological fluids of patients.

The innovative daily customized external quality control by a specialist Radiopharmacist ensures very reliable results and guarantees clinical credibility, to the benefit of patients.
