List and deline 3 terms used in the Seld of radiation theraipy. (Refler to Chapter 19) Path

Answer 1

ANSWER.

1. Radiology procedure.

             It is a diagnostic procedure with the help of low intensity radiations

             for detecting abnormal changes in the internal organs and presence

             of life threatening illnesses.

2. Radiology treatment.

            It is a therapeutic method in which high intensity radiations are used for

            treating malignant tumors.

* Both Radiological procedures and treatments are used for independent purposes

   based on the health condition and need of the patient.

3. Five types of radiological procedures.

         * X-ray scan.

            * It is a diagnostic procedure in which short bursts of X-rays are used

             to detect pathological conditions.

         * Computed tomography (CT) scan.

            * It is a diagnostic procedure in which X rays are used to produce several

              cross sectional pictures of the body part with the help of a computer to

            get a two dimensional view of the internal organs for diagnosing pathological

              conditions.

       * Magnetic resonance imaging.(MRI) scan.

            * It is a diagnostic procedure in which a strong magnetic field used to produce

              three dimensional images of the internal organs for detection of abnormalites

              in a person.

        * Fluroscopy.

          * It is a diagnostic procedure in which X rays are used to produce fluorescent images

            of the body to detect abnormalities.

   * Positron emission tomography (PET) scan.

      * It is a diagnostic procedure in which radioactive substances are given intravenously

            and emit positrons from PET scanner to produce cross sectional images of metabolism

            of the body.

4. Three terms used in the field of radiation therapy.

                      1. Intracavitory therapy.

                      2. Mega voltage.

                      3. Orthovoltage.

      1. Intracavitory therapy.

                 * It is a type of radiation therapy in which radioisotopes are placed within the

                   body cavity adjacent to a tumor tissue.

       2. Megavoltage.

                 * It is the high energy radiation produced by machines which are used in X-ray

                   therapy for tumor.

       3. Orthovoltage.

                * It is the low energy radiation used in treatment of superficial cancers and palliative

                  therapy.
