All questions

Question 1

A patient arrives for an upper GI series with a history of suspected gastric outlet obstruction. The initial scout image reveals retained food particles in the stomach despite a 12-hour fast. What is the most appropriate next step in the imaging protocol?

  1. Proceed with the standard barium examination as scheduled to visualize around the food particles
  2. Reschedule the examination after extending the fasting period to 24 hours
  3. Perform gastric lavage to remove food particles, then proceed with water-soluble contrast medium (correct answer)
  4. Cancel the fluoroscopic study and order a CT scan with oral contrast instead
Explanation: When food particles are present despite adequate fasting (especially with suspected gastric outlet obstruction), gastric lavage should be performed to clear the stomach, followed by water-soluble contrast rather than barium to avoid potential complications. Option A risks aspiration and poor visualization. Option B ignores the underlying pathology causing retention. Option D abandons the diagnostic benefits of real-time fluoroscopic evaluation.

Question 2

A technologist is performing an air-contrast barium enema and notices that after the initial barium coating and air insufflation, there are multiple rounded filling defects in the sigmoid colon that change position when the patient is rotated. The patient has no clinical symptoms and normal laboratory values. What is the most likely explanation for these findings?

  1. Air bubbles trapped in residual mucus creating pseudopolyps that mimic true pathology (correct answer)
  2. Retained fecal material that was not completely evacuated during the bowel preparation process
  3. Multiple adenomatous polyps that are mobile due to long stalks connecting them to the bowel wall
  4. Early inflammatory pseudopolyps associated with subclinical inflammatory bowel disease
Explanation: When evaluating filling defects on a barium enema, the key distinguishing feature is whether they change position with patient movement. This mobility tells you everything about their nature. Air bubbles trapped in residual mucus create mobile, rounded filling defects that shift dramatically when you rotate the patient. This is exactly what you're seeing here - multiple rounded defects that change position with rotation in an asymptomatic patient with normal labs. These pseudopolyps are completely benign artifacts of the examination technique and represent trapped air rather than true pathology. Let's examine why the other options don't fit: B) Retained fecal material would typically be more irregular in shape and, while it might move slightly, it wouldn't demonstrate the dramatic positional changes that air bubbles show with rotation. C) Multiple adenomatous polyps, even if pedunculated with long stalks, remain tethered to specific locations on the bowel wall - they don't migrate freely throughout the colon segment like these filling defects. D) Inflammatory pseudopolyps from IBD would be fixed to the bowel wall, wouldn't change position with patient movement, and you'd expect some clinical symptoms or abnormal laboratory findings. The correct answer is A because only trapped air bubbles demonstrate this characteristic mobility pattern. Study tip: Remember the "mobility test" for barium enema filling defects - if they move freely with patient positioning, think air bubbles first. True pathology (polyps, tumors, inflammatory lesions) stays put because it's attached to the bowel wall.

Question 3

A patient undergoing a small bowel enteroclysis has the nasojejunal tube positioned in the proximal jejunum under fluoroscopic guidance. After beginning the barium infusion at 150 mL/minute, the patient develops severe cramping and the barium column shows a segmented, accordion-like appearance in multiple loops. Vital signs remain stable. What is the most appropriate immediate response?

  1. Reduce the infusion rate to 75-100 mL/minute and monitor for improvement in the bowel pattern (correct answer)
  2. Continue the current infusion rate since the accordion pattern indicates normal physiologic response to distention
  3. Stop the infusion immediately and administer IV glucagon to reduce bowel spasm and patient discomfort
  4. Increase the barium concentration while maintaining the same flow rate to improve mucosal coating
Explanation: When you encounter enteroclysis complications during the procedure, you need to recognize the signs of bowel spasm and respond appropriately to patient comfort while maintaining diagnostic quality. The segmented, accordion-like appearance of the barium column combined with severe cramping indicates bowel spasm caused by the infusion rate being too rapid for this patient's tolerance. Since vital signs are stable, this is a procedural issue rather than a medical emergency. Reducing the infusion rate to 75-100 mL/minute (Answer A) allows the bowel to relax while continuing the examination, typically resolving both the cramping and the irregular barium pattern. Answer B is incorrect because the accordion pattern is not normal—it specifically indicates spasm that will compromise image quality and cause patient discomfort. Answer C represents an overreaction; while glucagon can reduce bowel spasm, stopping the infusion entirely and administering medication isn't warranted when a simple rate reduction will solve the problem with stable vital signs. Answer D is counterproductive because increasing barium concentration while maintaining flow rate would likely worsen the spasm, and the current concentration is adequate for mucosal visualization once spasm resolves. Remember that enteroclysis infusion rates should always be adjusted based on patient tolerance. Start with standard rates (150 mL/minute), but be prepared to reduce them when patients develop cramping or when fluoroscopy shows irregular barium flow patterns. Patient comfort and optimal bowel distention go hand-in-hand—forcing high rates through spastic bowel produces poor images and unnecessary discomfort.

Question 4

During a double-contrast upper GI series, the radiologist identifies a 1.2 cm focal outpouching along the lesser curvature of the gastric antrum that retains barium and shows smooth, rounded contours. When the patient is repositioned prone, the lesion fills completely with barium and the surrounding mucosa appears normal. What additional imaging maneuver would best characterize this finding?

  1. Obtain compression views with the paddle to assess lesion mobility and relationship to the gastric wall
  2. Administer effervescent granules to increase gastric distention and better evaluate the lesion contours
  3. Perform water-siphon test to differentiate between ulcer crater and diverticular outpouching
  4. Image the patient in multiple oblique positions to profile the neck of the lesion (correct answer)
Explanation: The description suggests either an ulcer or diverticular outpouching. Oblique positioning to profile the 'neck' helps differentiate: diverticula have narrow necks connecting to the gastric lumen, while ulcers have broad-based craters. Option A provides general information but doesn't specifically differentiate these entities. Option B won't add diagnostic value for this distinction. Option C (water-siphon test) is not a standard technique for this differentiation.

Question 5

During a percutaneous transhepatic cholangiography (PTC), the needle successfully enters a dilated intrahepatic bile duct, but initial contrast injection shows only the peripheral ductal branches without central duct opacification. The patient has a history of pancreatic head mass. What is the most appropriate next step?

  1. Withdraw the needle slightly and redirect toward a more central ductal location for better access
  2. Increase contrast injection pressure to overcome the presumed obstruction at the ductal confluence
  3. Continue with therapeutic intervention by advancing a guidewire for drainage catheter placement
  4. Inject additional contrast volume slowly while monitoring for retrograde filling toward the obstruction (correct answer)
Explanation: In obstructed biliary systems, patience and gradual filling often allows visualization of the obstruction level and proximal ductal anatomy. This is diagnostic information needed before therapeutic planning. Option A risks losing ductal access. Option B could cause ductal rupture in an obstructed system. Option C is premature without full diagnostic evaluation of the ductal anatomy and obstruction level.

Question 6

A patient with suspected gastroparesis undergoes a gastric emptying study. After ingesting the radiolabeled meal, imaging at 4 hours shows 45% meal retention. However, the patient received metoclopramide 30 minutes before the study for nausea. How should this result be interpreted?

  1. The result confirms gastroparesis since 45% retention exceeds the normal threshold even with prokinetic medication
  2. The result is falsely normal due to metoclopramide acceleration, and the study should be repeated off medication
  3. The result indicates more severe gastroparesis than the percentage suggests, since prokinetic medication was administered (correct answer)
  4. The result is indeterminate and requires correlation with simultaneous liquid-phase emptying measurements
Explanation: Normal 4-hour retention is <10%. The 45% retention with metoclopramide (which accelerates gastric emptying) indicates severe underlying gastroparesis that persists despite prokinetic medication. Option A underestimates the severity. Option B is incorrect because the study still demonstrates significant pathology. Option D doesn't address the medication's impact on interpretation.

Question 7

During a hysterosalpingography procedure, initial contrast injection shows normal uterine cavity filling. However, when attempting to demonstrate tubal patency, contrast flows freely into the peritoneal cavity on the right side but shows only minimal spillage on the left with the tube appearing dilated and clubbed. What additional maneuver is most appropriate?

  1. Increase injection pressure gradually while monitoring fluoroscopically to overcome potential tubal spasm
  2. Reposition the patient to steep Trendelenburg position to facilitate gravitational contrast flow
  3. Wait 15-20 minutes and obtain delayed images to allow time for spasm resolution (correct answer)
  4. Inject glucagon intravenously to reduce smooth muscle spasm, then repeat contrast injection
Explanation: The findings suggest either tubal obstruction or spasm. Delayed imaging allows differentiation - true obstruction will persist while spasm may resolve, allowing delayed contrast passage. Option A risks tubal rupture if true obstruction exists. Option B doesn't address the underlying spasm vs. obstruction question. Option D uses glucagon inappropriately (it affects GI smooth muscle, not fallopian tubes).

Question 8

During a small bowel follow-through examination, the barium column reaches the cecum at 45 minutes, but there is a 6-cm segment in the mid-ileum where the contrast appears to form discrete, separated boluses rather than a continuous column. The patient reports cramping in that region. What does this finding most likely indicate?

  1. Normal peristaltic activity creating temporary segmentation that will resolve with continued observation
  2. Ileal stricture causing mechanical obstruction with pre-stenotic dilation and hold-up of contrast (correct answer)
  3. Crohn's disease with characteristic string sign indicating severe luminal narrowing
  4. Intussusception with the contrast outlining the telescoped bowel segments
Explanation: The combination of discrete contrast boluses, localized cramping, and normal transit time to the cecum suggests mechanical narrowing with intermittent passage of contrast through a stricture. Option A is incorrect because normal peristalsis doesn't create sustained separation with associated pain. Option C (string sign) presents as a thin, continuous thread of contrast, not discrete boluses. Option D would show a characteristic coiled-spring appearance with acute obstruction symptoms.

Question 9

During an ERCP procedure, contrast injection into the pancreatic duct shows normal caliber ductal system, but the patient develops severe epigastric pain and elevated serum amylase 4 hours post-procedure. The technologist's injection technique involved multiple rapid bolus injections to achieve adequate opacification. What is the most likely cause of the patient's symptoms?

  1. Allergic reaction to the iodinated contrast material causing delayed hypersensitivity response
  2. Sphincter of Oddi dysfunction triggered by the contrast material injection pressure
  3. Post-ERCP pancreatitis caused by excessive injection pressure and volume in normal pancreatic ducts (correct answer)
  4. Pancreatic ductal perforation from overfilling that was not visible on the fluoroscopic images
Explanation: Post-ERCP pancreatitis is a known complication, especially with aggressive injection techniques in normal pancreatic ducts which have limited capacity. Multiple rapid boluses can cause ductal overpressure and acinar injury. Option A doesn't explain the elevated amylase. Option B involves biliary rather than pancreatic symptoms. Option D would likely show extravasation on imaging and cause more immediate severe symptoms.

Question 10

A patient scheduled for a double-contrast barium enema has a history of severe diverticular disease and recent sigmoid colon perforation that was treated conservatively 6 weeks ago. The referring physician wants to assess healing. What modification to the standard protocol is most appropriate?

  1. Proceed with the standard double-contrast technique using room temperature barium and CO2 insufflation
  2. Use a single-contrast technique with diluted, water-soluble contrast and minimal insufflation pressure (correct answer)
  3. Perform the examination with high-density barium and increased air pressure to better visualize the diverticular pouches
  4. Cancel the barium enema and recommend CT colonography as the only safe imaging option
Explanation: Recent perforation (even if healed) requires extreme caution. Water-soluble contrast is safer than barium if re-perforation occurs, and minimal pressure reduces stress on potentially weakened bowel walls. Option A ignores the perforation history. Option C increases perforation risk with high pressure. Option D is overly conservative since water-soluble contrast enemas can safely evaluate healing in this timeframe.

Question 11

During ERCP room setup, which item is essential for imaging when contrast is injected into the bile ducts?

  1. Bone densitometry scanner to measure duct obstruction by density changes
  2. Mammography unit with compression paddles to reduce motion during endoscopy
  3. Portable ultrasound only, because iodinated contrast is not used in duct imaging
  4. Fluoroscopy unit with image capture capability for spot images during contrast filling (correct answer)
Explanation: This question tests knowledge of performing abdominal and gastrointestinal imaging procedures, focusing on contrast studies, as expected from entry-level radiologic technologists. Understanding these procedures involves knowing patient preparation, the use of contrast media, and specific safety protocols. For example, during ERCP, fluoroscopy captures dynamic duct filling.
