The suffix "-gram" commonly signifies a record or a written representation of data or information. In medical terminology, it often refers to various imaging techniques or graphs that document findings, such as in "radiogram" for a written report of an X-ray, or "electrocardiogram," which records the electrical activity of the heart. This demonstrates the significance of the suffix in conveying that a systematic record has been generated, reflecting observations or measurements taken in a medical context.

The other options, while related to medical terminology, do not accurately represent the meaning of "-gram." For instance, a type of disease and inflammation are typically signified by suffixes like "-itis" or "-pathy," and a measurement tool would not be described with "-gram." Understanding this can greatly enhance your proficiency in decoding medical terms and their implications in a clinical setting.
