Emerson Hospital also performs the following exams. For more information, click on the procedure’s title below.


An ERCP is a procedure that combines the use of a flexible, lighted scope (endoscope) with x-ray pictures to examine the tubes that drain the liver, gallbladder and pancreas. The endoscope is inserted through the mouth and gently moved down the throat into the esophagus, stomach and duodenum (part of the small intestine) until it reaches the point where the ducts from the pancreas (pancreatic ducts) and gallbladder (bile ducts) drain into the duodenum.


Hysterosalpingography (HSG) consists of radiographic imaging of the cervical canal, uterine cavity, fallopian tubes and peritoneal cavity during injection of contrast media with fluoroscopic visualization. Additional diagnostic studies may be necessary for complete diagnosis.


An arthrogram is a test using x-rays to obtain a series of pictures of a joint camera after a contrast material (such as a dye, water, air or a combination of these) has been injected into the joint. A special type of x-ray, called fluoroscopy, is used to take pictures of the joint.


A sialogram is an x-ray of the salivary ducts and glands. A catheter (a small flexible tube) is inserted through your mouth and into the duct of the salivary gland. A contrast medium is then injected into the duct. This allows the duct will show up on the x-ray. 


A voiding cystourethrogram is an x-ray study of the bladder and urethra that is done while the bladder is emptying. A catheter (a small flexible tube) will be gently inserted into the urethra (the tube that carries urine from the bladder to the outside of the body) and passed into the bladder. X-rays are taken from various angles while the bladder is full of contrast dye.
