Study Notes

Imaging Tests

  • CT scans use X-rays and computer technology to create detailed images of the body, including bones, muscles, fat, and organs.
  • MRI scans use a combination of large magnets, radio waves, and a computer to create detailed images of organs and structures within the body without radiation.
  • Electroencephalogram (EEG) records the brain's continuous electrical activity through electrodes attached to the scalp.
  • Positron emission tomography (PET) scans use a small amount of radioactive material to see how well organs and tissues are working.
  • Arteriogram (angiogram) is an X-ray of the arteries and veins to detect blockage or narrowing of the blood vessels.

Neurological Tests

  • Electrodiagnostic tests, such as electromyography (EMG) and nerve conduction velocity (NCV), evaluate and diagnose disorders of the muscles and motor neurons.
  • Spinal tap (lumbar puncture) measures the pressure in the spinal canal and brain and can remove cerebrospinal fluid (CSF) for testing.
  • Evoked potentials record the brain's electrical response to visual, auditory, and sensory stimuli.
  • Myelogram uses a catheter to guide dye to arteries in the heart to show up more clearly on X-ray images.

Heart (Cardiac) Tests

  • Heart (cardiac) CT scan uses an X-ray tube to collect images of the heart and chest.
  • Heart (cardiac) magnetic resonance imaging (MRI) scan uses a magnetic field and computer-generated radio waves to create detailed images of the heart.

Major Respiratory Diseases

  • Asthma
  • Chronic obstructive pulmonary disease (COPD)
  • Pulmonary fibrosis
  • Pulmonary Tuberculosis
  • Pneumonia
  • Lung cancer

Lung Procedures, Tests & Treatments

  • Spirometry measures the volume of air exhaled at specific time points during a forceful and complete exhalation.
  • Chest X-Ray looks for problems like pneumonia, cancer, or pulmonary fibrosis.
  • Computerized tomography (CT) or positron emission tomography (PET) scans are more advanced imaging tests to find problems.
  • Chest ultrasound uses high-frequency sound waves to make an image of the lungs.
  • Pulmonary angiogram focuses on the pulmonary arteries to spot a pulmonary embolism.

Invasive Tests

  • Bronchoscopy uses a small tube with a camera to look inside the airways for things like mucus, blood, or tumors.
  • Mediastinoscopy uses a similar tool to look at the space between the right and left lung lobes behind the breastbone.
  • Pleural biopsy uses a needle to get a sample of the tissue to figure out what's causing fluid buildup in the space between the pleura and lungs.
