Diagnostic Tests
Stack #25532
Pulmonary Angiography | Chest X-Ray | Bone Densitometry | CT Scan | Ultrasound | Electrocardiogram (ECG) | Esophagogastroduodenoscopy EGD |
---|---|---|---|---|---|---|
Injection of radiographic contrast into pulmonary arteries to visualize the pulmonary vasculature. | Radiographic imaging of the chest. Patient must be correctly positioned, take a deep breath and hold it until films are obtained. | A radioactive nucleotide is placed in a tube and passed over the bony area to be studied (usually the distal radius). A scintillator photon detector is placed on the opposite side to detect the number of photons passing through. | Computers re-create a 3D cross-sectional view of body structures after obtaining X-Ray information from the entire circumference of the body. | High frequency sound waves are directed at internal body structures and a record is made of the wave pulses as they are reflected back through the tissue. | A graphic representation of the heart's electrical impulses. | Enables direct visualization of the lumen of the esophagus, stomach, and duodenum. Can be used for biopsies of suspected pathologic material. |
Stress Testing | Paracentisis | Thoracoscopy | PET Scan | MRI | Lumbar Puncture | Bronchoscopy |
A noninvasive procedure that stresses the heart in some way then is evaluated in some way. Forms of this include exercise, chemical, and pacing | The insertion of a needle into the peritoneal cavity for removal of ascitic fluid. | This is used to directly visualize the pleura, lung, and mediastinum. A scope is placed through the chest after the lung is collapsed. | Radioactive chemicals that are normally absorbed by the organ being studies are administered to the patient then positron emissions are recorded in 2 or 3D images | Noninvasive diagnostic technique using a magnetic field and radiofrequency signals. | In this procedure a needle is placed in the subarachnoid space of the spinal column. The pressure can be measured, CSF obtained, or therapeutic or diagnostic agents administered. | Endoscopic visualization of the larynx, trachea, and bronchi. |
