A lumbar puncture or cultivation of cerebrospinal fluid: it is to obtain a sample of the cerebrospinal fluid, usually with the help of a needle and placing the patient in a given position.

Amniocentesis: pregnant women is carried out to detect problems in the fetus. It introduces a needle into the abdomen to extract a small amount of amniotic fluid.

Analysis: is to examine a sample of substances such as urine or blood to detect potential diseases.

Angiography: type of X-ray used to view the status of the veins and arteries. To capture these images injected a substance contrastive coloring that makes visible the arteries.

Audiometry: is used to evaluate the hearing of a person, for air and bone, through sound and vibration.

Biopsy: involves the removal of tissue internally for later analysis. Depending on the area from which it is planned to remove the tissue used different procedures.

Bone scan: proof of nuclear medicine in which the patient is injected radioactive substance. Then, a special camera allows you to see the amount of radioactive substance that has become every bone and the activity that emits radioactive each.

Broncoscopia: displays airway (larynx, trachea and bronchi) through the introduction of a flexible pipe, accompanied by a camera through the nose or mouth.

Cardiac catheterization: test done to check the status of the veins and arteries. It consists of introducing a catheter (thin, flexible tube), usually from the groin, the aorta vein to the heart. An X-ray machine lets you capture images in real time.

Cistometria: shows the pressure that occurs in the interior of the bladder in relation to the amount of liquid (urine) in its interior.

Colangiografia: technique used to visualize the biliary tract (kidney ducts), using a substance contrastive and X-ray

Colonoscopy: is used to detect any abnormalities in the interior of the colon via a camera attached to a tube that is inserted by the patient's anus.

CT (Computed Axial Tomography): Testing is done via a scanner that transmits images of the interior of the human body to a computer. Sometimes, they are used substances contrastivas concealing certain tissues of the body to stop the action of others.

Densiometria bone: is used to measure bone density. It involves the application of low-intensity X-rays at different areas depending on what you want to evaluate.

Echocardiography: type of ultrasound that is performed to detect abnormalities in the functioning of the heart.

Electrocardiogram: consists of measuring the electrical activity of the heart and the regularity of their beats. At the patient at rest was placed different electrodes that will result in a graph, which reflects the activity of the heart.

Electromiograma: test that measures the electrical activity of muscles through nerve impulses to reach them. With needle electrodes are introduced into the muscles where it is going to study the injury or damage.

Electronistagmograma: involves registering involuntary movements of the eye using some electrodes that are placed on and around them.

Endoscopy: involves the introduction of a device called an endoscope (flexible tube with a light and a camera) inside the body. It serves, for example, to perform a biopsy or detect any abnormalities.

Enema opaque: a technique that makes it possible to visualize the interior of the large intestine using X-ray and a substance contrastive.

Espirometria: is performed to assess the patient's lung capacity. This connected to a device called a peak flow meter must make maximum inspiration and then expel all the air.

Evidence of cardiac effort: involves recording the electrical activity of the heart of a person while performing physical exercise.

Evidence of the loop: it is to verify the fragility of the capillary walls. It consists of observing the small blood stains that occur in an area previously oppressed with a bow.

Evoked potentials: consists of measuring the ability of sensory pathways. If the answers to the stimulus or not arrive arrive later than expected is that there is an anomaly in the functioning of the nervous system.

Histerosalpingografia: it is a radiographic technique makes it possible to visualize the interior of the uterus.

Laparoscopy: displays the abdominal organs and other nearby through a device composed of a flexible tube and a camera that is inserted into a small incision in the abdominal area.

Laringoscopia: it is to know the inside of the pharynx, either through a mirror placed in the upper palate or larynx to introducing a device that is called a laryngoscope.

Linfografia: technique that reveals vessels and lymph nodes using X-rays and administer intravenous form of a substance contrastive.

Mammography: using X-ray images are obtained from the interior of the breast to detect any abnormalities as a benign or malignant.

Mielografía: radiography of the spinal cord in which previously has injected a liquid contrastive allowing the shape of the medullary cavity. It is used for example to detect discal hernia.

Nuclear magnetic resonance: lets you capture images from inside the body in three dimensions. The patient is introduced into a tube so that through a magnetic field and radio waves are captured images of the precise area that is desired.

Pap: see vaginal cytology.

Paracentesis: is performed to detect any illness or for extracting fluid accumulated in this area so abnormal. It consists in an abdominal puncture with a needle.

PET (positron emission tomography): nuclear medicine procedure based on the imaging of the body from the radioactivity emitted positrons (radioactive substances) administered in tiny amount to the patient.

Proof of Rumple-Leede: see test loop.

Rinomanometria: technique used to measure the resistance presented by the nostrils to the passage of air. It uses a device connected to the nostrils and to a computer.

Rinometria acoustics: a study of the shape and amplitude of the nostrils. It was made from data obtained by the shape and amplitude that takes a sound wave in the nasal cavity of the patient.

Sialografia: X-ray technique used to observe the salivary glands and their ducts with the help of a substance contrastive.

Ultrasound: a technique that uses ultrasound to get images of internal organs. It is a routine test to monitor the fetus during pregnancy.

Urografia: technique that reveals the urinary system using X-ray and the administration of a substance contrastive.

Vaginal cytology: gynecologist scratched the surface of the uterus to obtain a sample of cells that were subsequently analyzed in order to detect any abnormalities.
