Why Is an Abdomen and Pelvis CT Scan Done?

A CT scan of the abdomen and pelvis is a valuable imaging test used to diagnose a wide range of medical conditions affecting the digestive, urinary, reproductive, and vascular systems. It provides detailed cross-sectional images that help doctors identify abnormalities and guide treatment plans.

‍
1.Common Diagnostic Purposes

Detection of Abnormalities

A CT scan can detect and assess various structural abnormalities in the abdomen and pelvis, such as:

• Tumours and masses – Identifies both benign and malignant growths in organs like the liver, kidneys, pancreas, and reproductive system.
• Cysts and fluid-filled sacs – Detects ovarian cysts, pancreatic cysts, or kidney cysts, which may need monitoring or treatment.
• Inflammation and infections – Help diagnose conditions like diverticulitis, appendicitis, pancreatitis, colitis, or abscess formation.

Organ Evaluation

A CT scan provides a detailed examination of major organs in the abdomen and pelvis, including:

• Liver – Checks for liver disease, cirrhosis, fatty liver, or tumours.
• Kidneys – Identifies kidney stones, infections, cysts, or signs of kidney disease.
• Pancreas – Helps diagnose pancreatitis, pancreatic tumours, and cysts.
• Intestines (Small and Large Bowel) – Detects bowel obstructions, Crohn’s disease, ulcerative colitis, and polyps.
• Bladder – Assesses for bladder stones, tumours, or structural abnormalities.
• Reproductive Organs – Examines conditions in the uterus, ovaries, prostate, or testicles, including fibroids, cysts, or cancers.

Pain Investigation

Doctors often recommend a CT scan to help determine the cause of unexplained abdominal or pelvic pain, such as:

• Severe or persistent stomach pain – This can indicate appendicitis, gallstones, pancreatitis, or intestinal obstruction.
• Pelvic pain in women – Helps diagnose ovarian cysts, fibroids, endometriosis, or pelvic inflammatory disease (PID).
• Unexplained weight loss, bloating, or digestive issues – May help identify cancers, inflammatory diseases, or malabsorption conditions.

Trauma Assessment

CT scans are crucial in emergency settings to detect injuries resulting from accidents, falls, or blunt trauma. They help identify:

• Internal bleeding – Detects blood accumulation in the abdomen or pelvis, often caused by ruptured organs or blood vessels.
• Organ damage – Assesses injuries to the liver, spleen, kidneys, or intestines.
• Fractures – Identifies pelvic or spinal fractures that may require urgent medical attention.

2. Pre-Surgical and Post-Surgical Evaluation‍

• Pre-surgical planning – CT imaging helps surgeons plan procedures by providing detailed organ and vascular structures.
• Post-surgical monitoring – A CT scan can check for complications such as infections, leaks, or internal bleeding after surgery.
  ‍

3. Cancer Staging and Monitoring

CT scans are commonly used to:

• Determine the stage of cancers affecting the abdomen and pelvis.
• Monitor tumour growth or spread to nearby organs or lymph nodes.
• Evaluate the effectiveness of cancer treatments such as chemotherapy or radiation therapy.
  ‍

4. Vascular Conditions and Blood Flow Issues

A CT angiography (CTA) of the abdomen and pelvis helps detect:

• Aneurysms (abnormal blood vessel bulging) – Common in the aorta and may require surgical intervention.
• Blood clots (Deep Vein Thrombosis – DVT or Pulmonary Embolism – PE) – Can be life-threatening if untreated.
• Narrowed or blocked arteries – This may lead to conditions like intestinal ischemia or kidney problems.

CT Scan of the Stomach: Purpose and Uses

A CT scan of the stomach is a highly effective imaging technique used to evaluate various gastric conditions by providing detailed cross-sectional images of the stomach and surrounding structures. It helps doctors detect abnormalities, inflammation, blockages, and tumours, allowing for early diagnosis and treatment planning.
‍
‍

Stomach Conditions Potentially Diagnosed

CT scans are valuable tools in diagnosing various stomach conditions. They can help identify both benign and malignant gastric tumors, providing details about their size, shape, and potential spread to nearby tissues. CT imaging is also useful in detecting stomach ulcers, which may cause pain, bleeding, or digestive issues. Inflammation of the stomach lining, known as gastritis—whether chronic or acute—can be visualized, particularly when linked to infections like H. pylori, excessive alcohol use, or long-term NSAID use. Abnormal thickening of the stomach wall, which may indicate stomach cancer, gastritis, or peptic ulcer disease, can also be assessed, allowing clinicians to distinguish between inflammatory and tumor-related changes. Additionally, CT scans can detect digestive tract blockages caused by adhesions, hernias, tumors, or inflammatory bowel disease (IBD), which often present with nausea, vomiting, abdominal pain, and impaired digestion. In cases of unexplained gastrointestinal bleeding, CT imaging can help pinpoint the source, whether from an ulcer, tumor, or vascular abnormality. The scan is also effective in diagnosing hiatal hernias, where a portion of the stomach moves through the diaphragm, causing symptoms such as acid reflux and chest pain. Finally, CT scans are crucial in identifying life-threatening stomach perforations by detecting free air in the abdominal cavity, prompting immediate medical attention.
‍
‍

When Is a Stomach CT Scan Recommended?

Doctors may recommend a stomach CT scan if you experience:

• Unexplained or severe abdominal pain
• Persistent nausea, vomiting, or difficulty swallowing
• Unexplained weight loss or loss of appetite
• Chronic acid reflux or heartburn symptoms
• Signs of gastrointestinal bleeding (black stools, vomiting blood)
• A history of stomach ulcers or suspected gastric tumours

A stomach CT scan is often part of a larger abdominal CT scan, which examines other digestive organs like the liver, pancreas, intestines, and gallbladder to provide a comprehensive diagnosis.

‍

Are a stomach CT scan and an abdominal CT scan the same?

While an abdominal CT scan includes imaging of the stomach, it also covers other organs such as the intestines, liver, and pancreas. A dedicated stomach CT scan may focus specifically on stomach-related issues. However, a stomach CT may not always be the most useful, so always discuss options with your doctor. |

Preparation for the Scan

Patients may need to fast for 4-6 hours before the scan. Depending on the procedure, oral, IV, or rectal contrast may be required to enhance image clarity. Before using contrast dye, allergy history and kidney function tests are checked to ensure safety. Patients should wear loose clothing and remove metal objects such as jewelry and belts to prevent image interference. Additionally, kidney function is assessed before contrast administration to minimize any potential risks.

How the CT Scan Procedure Works

During the scan, the patient lies flat on their back on a motorized CT table, with straps or cushions used if needed to maintain the correct position. If required, a contrast dye may be administered to enhance image clarity. Depending on the condition being evaluated, different types of contrast may be used: oral contrast (a liquid solution to highlight the stomach and intestines), IV contrast (injected into a vein to enhance blood vessels and organ structures), or rectal contrast (used for better visualization of the lower digestive tract). Patients with a history of allergies to contrast dye or kidney disease should inform their doctor before the scan.

The scanning process involves a rotating X-ray beam that captures multiple cross-sectional images of the abdomen. The CT machine takes hundreds of images in seconds, which are processed into detailed 3D visuals of the abdominal organs. Patients may be asked to hold their breath briefly to prevent motion blur.

The entire procedure duration typically ranges from 10 to 30 minutes, depending on whether contrast is used. After the scan, patients are usually observed for a few minutes to ensure there are no adverse reactions to the contrast dye, if administered.

Risks and Safety Considerations

Radiation Exposure: Modern CT scans use low-dose techniques to minimize radiation exposure while maintaining image quality.

Contrast Dye Risks: Some patients may experience mild side effects, such as a warm sensation or a metallic taste. In rare cases, severe reactions like allergic responses or kidney concerns may occur.

Pregnancy Considerations: For pregnant women, alternative imaging methods such as ultrasound or MRI may be recommended to avoid radiation exposure.

‍

Interpreting Results

Normal vs. Abnormal Findings

Normal: Organs appear structurally sound with no visible abnormalities.

Abnormal: Presence of tumours, cysts, infections, or internal bleeding.

Next Steps After the Scan

Further tests: Biopsies, MRI, or PET scans may be recommended. This would be discussed with your doctor. 

Consultation with specialists: A radiologist or physician will discuss findings and potential treatments.

Alternatives to CT Scan for Abdomen and Pelvis

• Ultrasound: Preferred for pregnancy, gallbladder issues, and kidney stones.
• MRI: Better for soft tissue evaluation without radiation exposure.
• X-ray: Limited use, mainly for detecting bowel obstructions or fractures.
