So I’ve been studying and preparing for my radiology and imaging diagnostics exam on Thursday, for something so simple there are an absolute ton of different procedures and techniques that can be used so I’ve decided to share a few of my favourites here. These are all contrast meaning that a special liquid is used that shows up on radiographs (xrays) better to outline hollow structures.
So if we start with the urinary tract..
Urography – Is used to describe a study when contrast material is injected into the blood which then travels to the kidneys and then to the bladder. This study is broken down further into smaller stages including…
Angiogram is when this contrast material is in the blood vessels and shows these vessels
Nephrogram is when this contrast material is in the kidneys showing the different structures
Pyelogram is when the contrast material starts to be collected in the renal pelvis, ureters and the bladder.
Cystography is an xray of the bladder, which can be done either with contrast material, or with air which is known as a negative contrast material. Sometimes it is even done with both which is a double contrast cystography.
Urethrography is when a x-ray is needed of the urethra, and is done in a retrograde manner filling the urethra with contrast material from the end. In females a vaginourethrography can be done instead.
Arthrography is the injection of contrast material into a joint to get a better look at the surfaces and shape of it.
Portovenography is a procedure that is usually used surgically to investigate shunts (where the blood bypasses certain organs – usually the liver) by injecting contrast material into the vein and taking a radiograph to see where it goes.
Lymphangiography is where the contrast material is used to test the lymphatic system which is responsible for collecting any loose fluid within the body and returning it back to the blood.
Sinography is used to look at the sinuses.
Dacryocystography is a technique that is used to look at the lacrimal canal which is responsible for draining the eye.
Sialography is used for inspecting the salivary glands.
And last but not least, Myelography which is used for inspecting the spinal canal (and spinal cord) by injecting contrast material into the space.
