What can I expect on the day of my appointment?

All of our imaging practices have procedures in place to ensure the safety of our patients and staff. These include:

• Increased cleaning and disinfection protocols for all equipment and surfaces in all common and clinical areas and between each appointment. 
• Hand sanitizer and appropriate disinfecting wipes in each clinical area. 
• Managing patient schedules and waiting rooms to ensure appropriate social distancing.  
• Universal mask policy for patients, visitors and staff. 

All patients and visitors are clinically screened upon arrival including a temperature check.

Patient verification is an important part of your safety and you will be asked to verify your identification and your exam several times during your appointment. Our check-in staff will review your completed registration forms with you.

For many exams you will not have to change into a gown unless you are wearing something that contains metal (see guidelines above).  Some exams do require that you are in a gown. You will be asked to remove and place your electronic devices, wallet, credit cards, metro card, watch, jewelry, belt, hairpins, eyeglasses, hearing aid, or any removable dental pieces into the provided lockers. 

How is Fluoroscopy performed?

• You will be positioned on the x-ray table.
• A special x-ray scanner will be used to produce the fluoroscopic images of the body structure being examined or treated.
• Though each examination is different, you may be asked to drink a contrast agent while we take these images.  Specific instructions will be provided at the time of the exam.

Our staff is available to address any questions or concerns that you might have before, during, or after your appointment. Please call (212) 746-6000 if you wish to speak with us.

Fluoroscopy

What is fluoroscopy?

Fluoroscopy is a study of moving body structures - similar to an x-ray "movie." A continuous x-ray beam is passed through the body part being examined, and is transmitted to a TV-like monitor so that the body part and its motion can be seen in detail.

Fluoroscopy, as an imaging tool, enables physicians to look at many body systems, including the skeletal, digestive, urinary, respiratory, and reproductive systems. Fluoroscopy may be performed to evaluate specific areas of the body, including the bones, muscles, and joints, as well as solid organs such as the heart, lung, or kidneys.

Fluoroscopy is used in many types of examinations and procedures, such as barium x-rays, cardiac catheterization, arthrography (visualization of a joint or joints), lumbar puncture, placement of intravenous (IV) catheters (hollow tubes inserted into veins or arteries), intravenous pyelogram, hysterosalpingogram, and biopsies.

Fluoroscopy may be used alone as a diagnostic procedure, or may be used in conjunction with other diagnostic or therapeutic media or procedures.

In barium x-rays, fluoroscopy used alone allows the physician to see the movement of the intestines as the barium moves through them. In cardiac catheterization, fluoroscopy is added to enable the physician to see the flow of blood through the coronary arteries in order to evaluate the presence of arterial blockages. For intravenous catheter insertion, fluoroscopy assists the physician in guiding the catheter into a specific location inside the body.

Barium X-Rays (Upper and Lower GI)

What are barium x-rays?

The use of barium with standard x-rays contributes to the visibility of various characteristics of the Gastrointestinal (GI) tract. Barium is a dry, white, chalky, metallic powder that is mixed with water to make barium liquid. Barium is an x-ray absorber and appears white on x-ray film. When administered into the GI tract, barium coats the inside wall of the esophagus, stomach, large intestine, and/or small intestine so that the inside wall lining, size, shape, contour, and patency (openness) are visible on x-ray. This process shows differences that might not be seen on standard x-rays. Barium is used only for diagnostic studies of the GI tract. As an alternate to barium, a clear watery dye may be used in certain situations.

Fluoroscopy is often used during a barium x-ray. Fluoroscopy is a study of moving body structures - similar to an x-ray “movie.” A continuous x-ray beam is passed through the body part being examined, and is transmitted to a TV-like monitor so that the body part and its motion can be seen in detail. In a barium x-ray, fluoroscopy allows the radiologist to see the movement of the barium through the GI tract as it is administered through the mouth or the rectum.

Why are barium x-rays performed?

Reasons for performing barium x-ray procedures may include the following:

• abdominal pain
• bleeding from the rectum
• blood in the vomit
• bowel movement changes
• chronic diarrhea or constipation
• pain or difficulty swallowing
• unexplained weight loss
• unusual bloating
• to detect anatomical abnormalities

Additional procedures are often performed in conjunction with or as a result of barium x-rays. These procedures may include endoscopic examinations (an endoscope is a thin, flexible tube that is inserted into a body cavity and, using fiber optic technology, provides direct visualization of the inside of the cavity), computerized tomography (CT) or magnetic resonance imaging (MRI) scans, and intra-cavity ultrasound.

What are the different types of barium x-ray procedures?

There are three types of barium x-ray procedures, including the following:

• barium enema (also called lower GI series)
• barium small-bowel enema (also called enteroclysis)
• barium swallow (also called upper GI series)

Barium Enema

What is a barium enema?

A barium enema involves filling the large intestine with diluted barium liquid while x-ray images are being taken. Barium enemas are used to diagnose disorders of the large intestine, colon, and rectum. These disorders may include colonic tumors, polyps, diverticula, and anatomical abnormalities.

How is a barium enema performed?

Usually, a barium enema can be performed on an outpatient basis. The patient may be asked to do the following in preparation for a barium enema:

• Drink clear liquids the day before the examination.
• A special liquid diet one to two days prior to the procedure.
• Take a laxative, suppository, or drug to cleanse the bowel.
• Refrain from eating and drinking after midnight on the night before the examination.

These measures are done to empty the large intestine, as any residue (feces) can obscure the image. However, a barium enema may be done without preparation, for example, to diagnose Hirschsprung's disease.

Barium enemas are performed in two ways:

1. single-contrast image - when the entire large intestine is filled with barium liquid. Single-contrast images show prominent abnormalities in the large intestine.
2. double-contrast image - when a smaller quantity of thicker barium liquid is introduced to the large intestine, followed by air. Double-contrast images show smaller surface abnormalities of the large intestine, as the air prevents the barium from filling the intestine. Instead, the barium forms a film on the inner surface.

Although each hospital may have specific protocols in place, generally, a barium enema procedure follows this process:

1. The patient will be positioned on an examination table.
2. A rectal tube will be inserted into the rectum to allow the barium to flow into the intestine
3. The radiologist will use a machine called a fluoroscope (a device used for the immediate showing of an x-ray image).
4. During the procedure, the machine and examination table will move and the patient may be asked to change positions.
5. After the procedure, a small amount of barium will be expelled by the body immediately. The remainder of the liquid is later excreted in the stool. Barium liquid may cause constipation and light colored stools. Following the examination, the patient may be asked to eat foods high in fiber and drink plenty of fluids to help expel the barium from the body
6. Additional x-rays may be made immediately after the procedure in order to obtain greater details of the area under examination. Often, additional x-rays are made after the barium has been excreted from the bowel, which is usually one or more days after the procedure.

Barium Small-Bowel Enema

What is a barium small-bowel enema?

A barium small-bowel enema is also called enteroclysis. The procedure involves filling the small intestine with barium liquid while x-ray images are being taken. Barium small-bowel enemas are used to diagnose disorders of the stomach and small intestine, such as ulcers and tumors.

How is a barium small-bowel enema performed?

Usually, a barium small-bowel enema can be performed on an outpatient basis. Patients may be asked to refrain from eating or drinking after midnight on the night before the examination. An enema or laxative may be given on the day before the test to clear feces from the bowel.

Although each hospital may have specific protocols in place, generally, a barium small-bowel procedure follows this process:

1. The patient will be positioned on the examination table.
2. The radiologist will use a machine called a fluoroscope (a device used for the immediate showing of an x-ray image).
3. A small tube will be inserted through the mouth or nose into the stomach and small intestine. Barium will be passed through the tube to the small intestine as x-ray images are taken.
4. Following the examination, the patient may be asked to eat foods high in fiber and drink plenty of fluids to expel the barium from the body.
5. Additional x-rays may be made immediately after the procedure in order to obtain greater details of the area under examination. Often, additional x-rays are made after the barium has been excreted from the bowel, which is usually one or more days after the procedure.

Barium Swallow

What is a barium swallow?

A barium swallow, also called an upper GI series, is an examination of the esophagus and stomach using barium to coat the walls of the upper digestive tract so that it may be examined under x-ray. Barium swallows are used to identify any abnormalities such as tumors, ulcers, hernias, pouches, strictures, and swallowing difficulties.

How is a barium swallow performed?

Usually, a barium swallow can be performed on an outpatient basis. Patients may be advised not to eat or drink after midnight on the night before the examination.

Although each hospital may have specific protocols in place, generally, a barium swallow procedure follows this process:

1. The patient will be asked to drink the barium liquid and to swallow baking soda crystals. It is important not to belch, as the gas assists the radiologist in evaluation.
2. The patient will stand behind a machine called a fluoroscope (a device used for the immediate showing of an xray image).
3. The patient may be asked to move in different positions and to hold his/her breath while the x-rays are taken.
4. If the small intestine is to be examined, the patient may be asked to drink additional barium and a series of x-rays will be taken until the barium reaches the colon.
5. Following the examination, barium may cause constipation. The patient may be advised to drink plenty of fluids and eat foods high in fiber to expel the barium from the body.

An upper gastrointestinal study with a small bowel follow-through is another type of barium study that may be used to evaluate certain conditions such as irritable bowel syndrome (IBS), unexplained gastrointestinal bleeding, chronic/recurrent abdominal pain, and vomiting.
