One Step Diagnostic provides comprehensive nuclear medicine services, including organ function investigations, PET imaging,  cancer studies, radioassay, and thyroid therapies.

Our certified nuclear medicine technologist will administer a small dose of radioactive material during the procedure, typically via intravenous injection. The substance momentarily emits gamma rays from the gland or organ in question. A sensor or gamma camera detects the rays on the patient, and the acquired data can be translated into diagnostic images. The radioactive material injected is in trace amounts and only lingers in the body for a brief period of time.

If you require additional information about the nuclear medicine services offered by One Step Diagnostic, please call (713) 461-7272.

What is Nuclear Medicine?

Nuclear medicine technology involves the use of radioactive materials, called radiopharmaceuticals, to create images of organs, study body functions, analyze biological specimens and treat disease. Nuclear medicine technologists apply the art and skill of diagnostic imaging and therapeutics through the safe and effective use of radionuclides.

For organ-imaging procedures, radiopharmaceuticals are administered to patients intravenously, orally or by inhalation. The radioactive material concentrates in a specific organ or organ system. Instruments called scintillation cameras can detect the radiation emitted by the radiopharmaceutical concentrated in the organ. The camera produces a computer image of the organ.

The images allow medical professionals to study the structure and measure the function of the organ and to identify tumors, areas of infection or other disorders. The radiation dose is small, and the patient experiences little or no discomfort during the procedure.
