Laboratory of Radiological Sciences and Imaging

The Laboratory of Radiological Sciences and Imaging (LCRI) is a part of the Facultad de Ciencias Exactas y Naturales, created through the  Resolution N° 269- 2008 of the Faculty’s Council and implemented since October 2nd, 2008 under the supervision of Prof. MSc. Fredy Julián Gómez Grance.

LCRI has entered various strategic agreements of scientific and technical cooperation with institutions that offer services or supervise activities linked to the use of ionizing radiation sources and generators. The mentioned institutions are the Comisión Nacional de Energía Atómica, the Centro  de Diagnóstico y Tratamiento Nuclear, the Instituto Nacional del Cáncer, the Clínica Terapéutica, the Hospital Nacional de Itagua Guazu, the IMAGEN MEDICA group, the Facultad de Ciencias Médicas, the INERAM “Prof. Dr. Juan Max Boettners, the Ministerio de Salud Pública y Bienestar Social, and the company RADIOFARMA.

The Laboratory performs research related to ionizing radiation, and publishes its results on the Faculty’s peer-reviewed scientific journal “Reportes Científicos de la FACEN”; whose editorial board  is composed of distinguised members of the Faculty.

Since its creation, the Laboratory has performed quality control and consultancy services in the field of radiodiagnostics and nuclear medicine, according to the availability of measurement equipment and requests received.

Overall Goals
  • Ensuring that the use of ionizing radiations in local medical, industrial, and research facilities comply with the standards of use, at the lowest possible cost and with the lowest risk to health, through the provision of services to said institutions.
  • Promoting scientific and technological knowledge in the fields of teaching, research, and technological applications, in order to ensure the safe use of ionizing radiation.

 

Current status

The LCRI provides support to: undergraduate and graduate students to enhance Research related to their Thesis, as well as interns who are interested in a Scientific Initiation, with all possible Technical and Professional support.

Since mid-2011, the Laboratory has new dosimetric equipment for conducting Quality Control, Advice and Research in the area of ​​Ionizing Radiation applied to Medicine.

On the other hand, the Laboratory is intended to form part of Multidisciplinary Networks, to strengthen its intervention in the improvement of the Quality of Life of the population through the peaceful use of Ionizing Radiations in the Medical area.

It has also been awarded with CONACYT / PROCIENICIA, specifically in the project “INV-047-Biological Dosimetry based on the Comet Test and Micronuclei of patients exposed to Iodotherapy in Nuclear Medicine Treatments”.

Technology and equipment

The Laboratory of Radiological Sciences and Imaging has equipment for the realization of radiation dose measurements and parameters that involve the quality of the image, in that sense all its equipment are calibrated and certified traceable to NIST (National Institute of Standards and Technology of USA) and the PBT (Physikalisch-Technische Bundesanstalt).

Among the equipment that we counted we can mention cameras of ionization, detectors of solid state, phantoms and accessories.
