Nuclear Medicine

Nuclear Medicine is a medical specialty using radionuclides, the result of nuclear emissions in unstable elements of low energy and short half-lives. They are used for prevention, diagnosis, therapy and medical research.

Doctors Hospital has gamma cameras, radiation detection equipment, advanced technology software that allows a precise evaluation of any functional alteration with the fusion of equipment such as the CT, which defines the anatomical part of the pathology detected.

The Department of Nuclear Medicine reinforces the ability and reliability of the diagnosis upon providing hybrid images, thus supporting the areas of oncology, neurology, cardiology, among others.

Radionuclides, together with different medications, form radioactive tracers. These are administered to the patient intravenously and they are used to study different functions of organs and systems, as well as for therapeutic purposes.

Technology and Equipment

Symbia TruePoint SPECT-CT combines a gamma camera with a double head, a variable 16 slice SPECT angle with a CT scanner for fast correction, exact attenuation, precise location and the fullest coverage of CT applications in the whole body. The new technology of the Symbia T 16 TruePoint SPECT-CT System in the Nuclear Medicine Department reinforces the capacity and trust, diagnosis with hybrid 16 slice SPECT-CT images, in the advanced evaluation of oncological, neurological, neurological, cardiological and scanning areas with calcium scores.

This double diagnostic image technique modality (SPECT-CT) present in hybrid machines is capable of correlating anatomical images and functional data of organs and systems, which is useful in a wide variety of diagnostic applications, especially in patients with different clinical problems.


This latest generation technology makes it unnecessary to reprogram patients with other equipment, allowing only one visit to the imaging unit and offering greater comfort to patients since its rapid speed of exploration helps attend more patients.

The Work Station of the SPECT-CT Hybrid System allows the reconstruction of images:

SPECT (Single Photon Emission Computed Tomography): image technique in nuclear medicine with the acquisition of tomographic slices (transaxial, coronal, sagittal) used for the functional analysis of organs and systems through the application of radionuclides, which in and of themselves have the ability to identify diseases in early stages, detecting molecular alterations before anatomical changes in the tissues or organs studied.

16 slice CT: diagnostic technique by anatomical images in tomographic slices (transaxial, coronal, sagittal and 3D reconstructions). .

Hybrid, functional and anatomical studies are carried out with the CT, in addition to correcting the attenuation factor. The latter is of prime importance in myocardium perfusion and fusion images, since it avoids false positives for ischemic pathologies.
