Chapter 7 Flashcards
Low energy x-rays used to measure bone thickness. Reveal areas of deficiency.
Bone Density Scan
X - rays used to get cross sectional imagery used to show tissue structures.
Computer Tomography
Focuses sound waves on blood vessels and measures blood flow.
Doppler Ultrasound
Imaging of the heart with high frequency sound waves.
Echocardiography
Magnetic field used to create detailed image. Useful for imaging the brain and tumors.
(MRI) Magnetic Resonance Imaging
X-ray recording of the breast.
Mammography
X-ray recording of the spinal chord.
Myelogram
High frequency sound waves that show movement, organ structures positions. Useful for detecting gall stones, fibroid tumors of the uterus, and ovarian tumors.
Ultrasonography
A radioactive substance injected, uptake in bones is recorded. Tumors in bone can be detected.
Bone Scan
A radioactive substance is injected and travels to specialized areas of the body. Used for tumors and in the brain used to evaluate memory disorders, seizure disorders ad brain tumors.
Positron Emission Tomography
Pulmonary Perfusion Scan
Radioactive particles are injected that travel to the lungs. Regions of obstructed blood flow can be seen.
Small quantity of suspected allergic substances are applied to the skin, any reaction is noted.
Allergy Test
Withdrawing fluid from a cavity or sac by suction through a needle or a tube.
Aspiration
Process of listening to sounds within the body, most often uses a stethoscope to determine the condition of the heart, lungs, blood vessels or detecting of fetal heartbeat.
Auscultation
Removing pieces of tissue from the body for examination under a microscope.
Biopsy
Introduction of a small hollow, flexible tube into a vessel or cavity of the body to withdraw or instill fluids.
Catheterization
Visual examination of the colon using a flexible tube, inserted through the rectum and passed into the large bowel.
Colonoscopy
Physician inserts a gloved finger into the patient’s rectum to detect rectal cancer. Used to detect prostate cancer.
Digital Rectal Exam
Recording electrical impulses from the heart. Useful for detecting abnormalities in heart rhythms / diagnosing heart disorders.
Electrocardiography
Connection of electrodes to the scalp to record electricity coming from within the brain. Used to evaluate patients in coma and study sleep disorders.
Electroencephalography
Probes symmetrical in size inserted through the vagina into the opening of the cervix, curette is then used to extract tissue for examination.
Dilation and Curettage
Exam of the abdominal cavity through an endoscope inserted into the abdomen.
Laparoscopy
Inserting small needle into a space surrounding the spinal cord to withdraw fluid for analysis.
Lumbar Puncture
Examination of the interior ear to check for obstruction, infection, fluid and ear perforation.
Otoscopy
