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.
