Area Scanned – Part of the body that will be in the x-ray beam.  Used on RSF-022 under the heading for computed tomography.

1.       Slices, thickness and spacing – If not defined in the protocol, information should be obtained from the person performing the exam in the CT department; unless it is a special procedure to be defined by the physician.

Area Viewed – Sections of the body that will be in the x-ray beam during a fluoroscopic procedure.  Used on RSF-022 form under the heading for fluoroscopy

1.        Percent of additional time for research – The percentage of radiation that is needed for the research (additional time)

2.        Percent of time medically indicated – Percentage of radiation the patient receives as standard of care.

CE – Closed to enrollment

CR – Continuing review

Critical organ – Organ that is most susceptible to radiation damage due to a radioisotopic procedure.  Used on RSF-021 form; all information for the RSF-021 can be found on the comparison table(s).

Critical organ absorbed dose – The amount of energy absorbed by the critical organ.  Needs to be provided on the RSF-021 form; information can be found on the RSF-035 form comparison table(s).

External Radiation – Radiation exposure to a subject/patient from a machine that produces radiation.  Examples:  Diagnostic radiology, fluoroscopy, radiation therapy, cardiac cath procedures, and special procedures.

IRB – Institutional Review Board

Internal Radiation – Radiation exposure from a radioactive material that is injected in a subject/patient in order to perform a nuclear medicine scan..

Non-Patient/Normal – Study participants that do not have the disease being studied, but who will be exposed to radiation as part of the study.

Patients – Patients who have the disease being studied and who will receive the experimental treatment.  These individuals will be exposed to the radiation involved in the research protocol.

Patient Controls – Patients who have the disease being studied, but who receive standard of care treatment or a placebo rather than the experimental treatment.  These individuals will be exposed to the radiation involved in the research protocol.

RDRC – Radioactive Drug Research Committee

RSC – Radiation Safety Committee

SHUR – Sub committee for the Human Use of Radiation in Research

Standard of Care (Medically Indicated) – Radiographic examinations that would be performed for the disease process being studied even if the participant was not enrolled in a research study.

View – The positions of the body relative to the x-ray beam.  Used on the RSF-022 under the heading for radiographic procedure.  (Example: AP, PA, Lat, Oblique)
