. What would you like to do?
X-ray imaging of blood vessels. A contrast substance is injected into a blood vessel ( vein or artery), and x-rays images are taken of the blood vessel
can detect blockage by clots, cholesterol plaques, or tumors or aneurysms( ballooning or dilating of the vessel wall)
x-ray recording of an artery and its branches after injection of a contrast substance into an artery.
x-ray examination of inside of a joint with a contrast medium
x-ray examinations with a liquid barium mixtur that is swallowed or given by enema to outline the surface of the gastrointestinal tract.
bone density scan
low energy xrays are ued for this study, which measures bone thinkness and reveals areas of the bone deficiency
procedures in which a catheter is passed via vein or artery into the chambers of the heart to measure the blood flow out of the heart and the pressures and oxygen contact in the heart chambers.
x-ray recordings or record of bile ducts
- ct or ct scan
- xray images that show the body in cross-section
- shows slices of the body
xray recording of the urinary bladder with a contrast medium so that the outline of the urinary bladder can be seen clearly
contrast substance is injected through catheter into the urethra and urinary bladder
digital subtraction angiography
a unique x-ray technique for viewing blood vessels by taking two images and subtracting one from another
first obtained without contrast material and then again after contrast is injected into the blood vessel
the first image is subtracted from the second so that the final image shows only contrast-filled blood vessels and not the surrounding tissues
technique that focuses sound sound waves on blood vessels and measures blood flow as echoes bounce off red blood cells.
- imaging of the heart by introducing high frequency sound waves through the chests into the heart.
- the sound waves are reflected back from the heart and echoes showing heart structure are displayed on a recording machine
very helpful diagnostic tool in the evaluation of diseases of the valves that separate the heart chambers and diseases of the heart muscle.
endoscopic retrograde cholangiopancreatography or ERCP
x-ray recording of the bile ducts, pancreas and pancreatric duct using radiopaque contrast injected through an endoscope, passed through the mouth, esophagus, and duodenum into the bile and pancreatic ducts and x-rays images are then obtained.
Endoscopic Ultrasonography or E-US
sound waves are generated from a tube inserted through the mouth into the esophagus . The sound waves bounce off internal structures and are detected by surface coils.
the study can detect enlarged cancerous lymph nodes and tumors in the chest and upper abdomen
xray recording or record of the esophagus performed after barium sulfate s swallowed
this test is part of the barium swallow and the upper gastroinestinal examination
an x-ray examination that uses a fluorescent screen rather than a photographic plate to show images of the body in motion. x-rays that have passed through the body strike a screen covered with a fluorescent substance that emits yellow-green light.
sound waves are used to visualize gallstones. this procedure has replaced the x-ray test known as cholecystography
x-ray recording or record of the uterus and fallopian tubes. Contrast material is inserted through the vagina into the uterus and fallopian tubes and xray images are obtained to detect blockage tumor.
Kidneys, ureters, bladder ( KUB)
XRAY images of the kidney, uterus and the urinary bladder, made without contrast material
Lower Gastronitestinal examination
Xray pictures of the colon taken after a liquid contrast substance called barium sulfate is insterted through a plastic tube(enema) into the rectum and large intestine.
Magnetic resonance imaging ( MRI)
a powerful magnetic field is created surrounding the whole patient, or only the head, and water molecules are aligned and then relaxed, generating electromagnetic currents that provide a detailed picture of organs and the blood vessels
