The serous membrane that lines the abdominopelvic walls is called the

peritoneum

The pathological accumulation of fluid in the peritoneal cavity is termed

ascites

A properly exposed abdominal image will exhibit all of the following, except the

pancreas

Which of the following are prime considerations in producing an optimal image of the abdomen? Apply compression Explain the breathing procedure to the patient Do not start the exposure for 1 to 2 seconds afgter suspension of respiration

2 and 3

The most commonly performed abdominal examination is referred to as a(n)

KUB

I’d a patient is unable to stand upright AP abdominal image, which position should be used?

Left lateral decubitus

Where is the center of the IR positioned for an AP abdominal image performed with the patient in the supine position?

Iliac crests

Where is the center of the IR positioned for an AP abdominal image performed with the patient in the upright position?

2 inches above the ilian crests

What is the respiration phase for an AP abdominal image obtained with the patient in the supine position?

Expiration

The central-ray angular ion for an AP abdominal image is

0 degrees

Where is the center of the IR positioned for an upright PA abdominal image?

2 inches above the iliac crests

What is the respiration phase for a AP or PA abdominal image obtained with the patient in the upright position?

Expiration

Where is the center of the IR positioned for an AP abdominal image obtained in the left lateral decubitus position?

2 inches above the iliac crests

What is the respiration phase for an AP abdominal image obtained with the patient in the left lateral decubitus position?

Expiration

One of the primary reasons a left lateral decubitus abdominal image is performed is to demonstrate

air-fluid levels

Demonstrating small amounts of intraperitoneal gas in patients with an acute abdomen is often necessary. How long should the patient lie in the left lateral position before exposure is made?

10 to 20 minutes

Which of the following is placed perpendicular to the long axis of the grid for a lateral projection of the abdomen?

Midcoronal plane

Where is the center of the IR positioned for a lateral projection of the abdomen performed with the patient in the dorsal decubitus position?

2 inches above the iliac crests

Which of the following are clearly shown on a lateral abdomen projection performed with the patient in the dorsal decubitus position? Prevertebral space Air-fluid levels Urinary bladded

1 and 2

All of the following organs lie in the abdominal cavity, except

urinary bladder

The outer portion of the sac that lines the abdominopelvic cavity is termed the

parietal peritoneum

The inner portion of the sac that covers the abdominal organs is termed the

visceral peritoneum

The folds of peritoneum that support the abdominal organs are called the Omenta Mesentery Pleura

1 and 2

The space between the two layers of peritoneum is called the

peritoneal cavity

What is the cavity posterior to the peritoneum?

Retropertioneum

All of the following are used to evaluate rotation on a KUB image, except

superimposed posterior ribs

Which structures are outlined with dots in this AP image of the abdomen?

kidneys

A three-way abdominal series may be ordered to rule out all of the following excpet

tumor mass

An ambulatory patient arrives to the radiology department complaining of abdominal pain for 3 days. The radiologist orders an abdomen series to rule out pneumoperitoneum. What positioning routine should be performed on this patient?

AP upright and left lateral decubitus

The upright PA chest projection can be used to demonstrate free air that may accumulate under the diaphragm.

True

Open Collimation provides radiation protection and improves image quality.

False
