Medical Diagnostic Tests
This Section is Part ofMedical Tutorials
CAT Scan - Computed Axial Tomography
is a medical imaging method employing tomography where digital geometry processing is used to generate a three-dimensional image of the internals of an object from a large series of two-dimensional X-ray images taken around a single axis of rotation.
PET - Positron Emission Tomography
Is a nuclear medicine medical imaging technique, which produces a three-dimensional image or map of functional processes in the body.
MRI - Magnetic Resonance Imaging
Also called magnetic resonance tomography (MRT) - is a method of creating images of the inside of opaque organs in living organisms as well as detecting the amount of bound water in geological structures.
Ultrasound
is sound with a frequency greater than the upper limit of human hearing, approximately 20 kilohertz/20,000 Hertz. Some animals, such as dogs, dolphins, bats, and mice have an upper limit that is greater than that of the human ear and thus can hear ultrasound.
X-ray
Are primarily used for diagnostic medical imaging and crystallography. Is a form of electromagnetic radiation with a wavelength in the range of 10 nanometers to 100 picometers (corresponding to frequencies in the range 30 PHz to 3 EHz).
MUGA Scan - Multiple Gated Acquisition Scan
Is a noninvasive nuclear medicine test to evaluate the function of the heart.
Endoscopy
It is a minimally invasive diagnostic medical procedure used to evaluate the interior surfaces of an organ by inserting a small scope in the body, often but not necessarily through a natural body opening. Through the scope, one is able to see lesions.
Esophagogastroduodenoscopy
In medicine (gastroenterology), esophagogastroduodenoscopy (EGD) or upper endoscopy is a diagnostic endoscopic procedure that visualizes the upper part of the gastrointestinal tract.
Colonoscopy
Is the minimally invasive endoscopic examination of the large colon and the distal part of the small bowel with a fiber optic camera on a flexible tube passed through the anus.
Endoscopic retrograde cholangiopancreatography
Also Known as ERCP .is endoscopy of the biliary tree and the pancreatic duct. By injection of contrast media, a retrograde image of both structures can be formed on X-ray, facilitating the diagnosis of obstruction, e.g. by gallstones or cholangiocarcinoma.
Bronchoscopy
In medicine, bronchoscopy is the visualization of the lower airways using a flexible or rigid endoscope.
Cystoscopy
Endoscopy of the urinary bladder via the urethra is called cystoscopy.
Hysteroscopy
Is the inspection of the uterine cavity by endoscopy.
Arthroscopy
(also called arthroscopic surgery) is a minimally invasive surgical procedure in which a physical examination of the interior of a joint is performed using an arthroscope, a type of endoscope that is inserted into the joint through a small incision.
Laparoscopy
Laparoscopic surgery, also called keyhole surgery (when natural body openings are not used), Band-Aid surgery, or minimally invasive surgery (MIS), is a surgical technique.
Barium Tests
Barium is a white liquid that shows up clearly on an X-ray. Once it is inside you, it coats the inside of the gullet, stomach or bowel. And so it shows up the outline of the organs on the X-ray.
Pap Smear
Pap smear (pap is an abbreviation for Papanicolaou)
Flow Cytometry
Is a technique for counting, examining and sorting microscopic particles suspended in a stream of fluid.
IVP - Intravenous Pyelogram
(also known as IVP, pyelography, intravenous urogram or IVU) is a radiological procedure used to visualize disturbances of the urinary system, including the kidneys, ureters, and bladder. Among other uses, IVP can detect kidney stones.
KUB
In medicine, KUB refers to a diagnostic medical imaging technique and stands for Kidneys, Ureters, and Bladder.
Mammography
Is the process of using low-dose X-rays (usually around 0.7 mSv) to examine the human breast.
HIV - AIDS Tests
HIV test kits used both to screen donor blood, blood components and cellular products, and to diagnose, treat and monitor persons with HIV and AIDS are regulated in the United States by the FDA.
Electroencephalography
Is the neurophysiologic measurement of the electrical activity of the brain by recording from electrodes placed on the scalp, or in the special cases on the cortex.
Echocardiography
The echocardiogram is an ultrasound of the heart. Using standard ultrasound techniques, two-dimensional slices of the heart can be imaged. The latest ultrasound systems now employ 3D real-time imaging.
ECG - Electrocardiogram
or EKG is a graphic produced by an electrocardiograph, which records the electrical voltage in the heart in the form of a continuous strip graph.
Holter Monitor
Also called an ambulatory electrocardiography device ), named after its inventor, Dr. Norman J. Holter, is a portable device for continuously monitoring the electrical activity of the heart for 24 hours or more.
Single Photon Emission Computed Tomography
Also called an SPECT ), is a nuclear medicine tomographic imaging technique using gamma rays. The technique results in a set of image slices through a patient, showing the distribution of a radiopharmaceutical like Technetium-99m.
Genetic Testing
allows the genetic diagnosis of vulnerabilities to inherited diseases, and can also be used to determine a person's ancestry.
Tumor Marker Tests
Tumor markers are specific substances found in the blood, urine or body tissues that arise from cells and are often elevated in cancer.
Blood Tests
Are laboratory tests done on blood to gain an appreciation of disease states and the function of organs.
Complete Blood Count
Also Known as CBC or full blood count (FBC) is a test requested by a doctor or other medical professional that gives information about the cells in a patient's blood. A CBC is also known as a "hemogram".
Liver Function Tests
Also Knwon as LFTs or LFs are groups of clinical biochemistry laboratory blood assays designed to give a doctor or other health professional information about the state of a patient's liver.
Radioimmunoassay
Is a scientific method used to test hormone levels in the blood without the need to use a bioassay.
Mantoux Test
or Mantoux screening test, Tuberculin Sensitivity Test, Pirquet test, or PPD test for Purified Protein Derivative) is a diagnostic tool for tuberculosis.
Heaf Test
is a diagnostic skin test performed in order to determine whether or not a child has been exposed to tuberculosis.
It is done in the United Kingdom to determine if the BCG vaccine is needed. Patients who exhibit a negative reaction may be offered BCG vaccination.
Gram Staining
Gram's method is an empirical method of differentiating bacterial species into two large groups (Gram-positive and Gram-negative) based on the chemical and physical properties of their cell walls.
Renal Function Tests
In medicine (nephrology) renal function is an indication of the state of the kidney and its role in physiology.
Creatinine Clearance
Is a method that estimates the glomerular filtration rate (GFR) of the kidneys.
Pulmonary Function Test & Spirometry
(PFTs) are a series of different breathing tests done by a trained pulmonary function technologist to learn about the lung health. It is also sometimes referred to as Spirometry.
Normal Laboratory Values
Obstetric Ultrasound Scan
Use of ultrasound scans during pregnancy. Since its inception in the medical field, it has become a very useful diagnostic tool in Obstetrics and applied very frequently.
