Presbycusis
Meniere’s Disease
Otosclerosis
anacusis
Arthroscopy
Direct Joint Visualization
Instrument is Arthroscope
Done by an orthopedic surgeon
Knee, shoulder, and ankle are most
common. Toe joints are also scoped with
increasing frequency.
Can be a diagnostic tool or a treatment tool
by removing tissue that is “dead”
Aspiration




Withdrawal of fluid from a joint
Can be done by any doctor in an
office setting.
A large bore needle is inserted into
the joint to remove the synovial
fluid.
Fluid can be examined under a
microscope for crystals (gout) or
cultured for bacteria (infection).
Biopsy





Remove of skin or other tissue for
examination.
Microscopic examination can reveal
“changed” cells. Ie: cancer
Breast, bone, muscle, and skin
Usually done to make a diagnosis.
When skin cancer is suspected, a
biopsy is also used to remove tissue.
Bronchoscopy



Used to visually examine the
bronchial tubes.
A “bronchoscope” is a flexible
camera that shows what the bronchi
look like.
The scope also serves as a suction
machine enabling the surgeon to
remove tissue to biopsy, examine
sputum, or foreign bodies.
Colonoscopy



A visual examination of the colon.
A colonoscope is used to biopsy or
excise tissue.
Done by a gastroenterologist.
Electrocardiogram




A visual record of the electrical
activity of the heart.
The instrument used is an
electrocardiograph.
Done by placing a series of
electrodes on the thorax to measure
electrical activity.
Can be done by a physician,
technician, or nurse.
Holter Monitoring
A device worn on the belt of a patient
with abnormal cardiac rhythm.
This is done when a regular EKG
shows no abnormality but when
symptoms still persist.
The device records all activity over a
24 hour period.
A cardiologist interprets the results.
Laparoscopy




Visual examination of the abdominal
cavity by the use of a laparoscope.
A small incision in the abdomen
allows a small camera to be inserted.
Used for gynecological procedures.
Also can be called a Peritoneoscopy.
Ophthalmoscopy




Visual examination of the eye.
Use of an ophthalmoscope
Is diagnostic for detection of eye
disorders
Done by an optometrist or
ophthalmologist.
Otoscopy


Visual examination of the ear and
eardrum (tympanic membrane)
Instrument is an otoscope.
Palpation



Physical touch
Examination of size, texture,
hardness, fluid, contents
Can be done by anyone
Pulmonary Function Tests



Determines the capacity of the lungs
by a series of tests of inspiration and
expiration.
Measures oxygen and carbon dioxide
use.
Instrument is a spirometer.
Retinoscopy



Tests to check “refractive index” of
eye.
Light is shone into eye and the
examiner sees how the light bends
(refraction).
Also to check the integrity of the
back of the eye.
Tonometry


Measures tension and pressure in the
eye.
A tonometer is the instrument used
to check for glaucoma.
Angiography



Radiographic study of the circulatory
system.
A radiopaque substance is used to detect
vascular abnormalities including tumors,
aneurysms, and clots (occulsions).
Different studies for body areas:
cerebral (head), coronary (heart),
peripheral (extremities), and pulmonary
(lungs)
Arthrography





Radiographic procedure to check for the
integrity of a joint.
Air (pneumoarthrograhy) or contrast dye
is injected.
Xrays taken under stress to check for
excess seepage into places where dye
shouldn’t be.
Done under local ansethesia by a
radiologist or orthopedic surgeon.
Podiatrists do arthrography to the foot and
ankle.
Bone Scan (scintography)




Radioactive isotope
Bone absorbs the isotope at places
where there is increased “blastic”
activity. Osteoblasts are cells that
lay down new bone.
Normal scans show no uptake.
Positive scans do not explain the
reason for the result. Very sensitive
but specific.
Cardiac Catheterization



Procedure to check the integrity of
the coronary blood vessels.
A catheter is placed in a large vessel
in the groin. The catheter is passed
to the heart vessels.
Xrays are taken to diagnose
occulsions of vessels.
Computer Axial Tomography (CAT)





Radiographic sectioning of the body.
X-rays are taken at a specified thickness.
When completed the individual slices are
put together by a computer (computer
generation).
The scanner and detector and parts of the
tube that encircle the body and record..
Can be used to examine the abdomen,
brain, chest, and extremities.
Done by specially trained technicians and
interpreted by radiologists.
Doppler Ultrasound



A test used to measure blood flow into a
body part.
Uses sound waves that are forced through
the skin and bounce back to a recording
probe. The result makes a sound that is
used to diagnose circulation problems.
Usually done on the large vessels of the
extremities. A specialized version is used
for the small vessels of the toes and penis.
Echocardiography



Uses sound waves (ultrasound) to
visualize the internal cardiac
structures (valves).
Used to examine the integrity of
heart valves.
Has taken the place of
catheterization for certain
procedures.
Magnetic Resonance Imaging
(MRI)



No radiation
Uses magnetic fields to produce an
image.
Useful for soft tissue structures
(muscle, tendon, ligament) whereas
CAT scans are useful for bones.
Xeroradiography



Technique that produces an image
using electrical means instead of
chemical means.
Permits lower exposure times
Useful for breast tumor diagnosis.
Arterial Blood Gas



Percutaneous puncture to assess the
exchange of oxygen and carbon
dioxide.
Blood is taken from an artery.
More painful than an intravenous
sample.
Bleeding Time



Used to assess how long it takes to
form a clot of a small cut or wound.
Used to determine platelet function.
Increased bleeding times is found in
patients with low platelet counts and
deficiencies of fibrinogen.
Cardiac Enzymes
Increases in these enzymes indicate
myocardial infarction (heart attack).
Complete Blood Count (CBC)



Used to measure the components of
blood.
RBC, WBC, Platelets, Hemoglobin,
and Hematocrit
Differential separates the different
types of WBC’s
