Colorectal cancer is the second-leading cause of cancer-related deaths in the United States, yet it is one of the most preventable forms of cancer when caught early. Screening makes all the difference, but many patients hesitate to undergo traditional colonoscopy because of the preparation, sedation, and recovery time involved. Fortunately, there’s another option. At Iowa Radiology, we offer CT colonography, also known as virtual colonoscopy, which provides a less invasive, highly accurate way to evaluate the colon and rectum.
What Is CT Colonography?
CT colonography uses advanced computed tomography (CT) technology to create detailed, 3D images of the colon and rectum. The exam is designed to detect polyps, precancerous growths, and cancers. Unlike traditional colonoscopy, CT colonography does not require sedation, meaning patients can resume normal activities immediately after the test. The preparation is often simpler as well, making the exam more accessible to those who may otherwise put off screening.
Why It Matters for Colorectal Cancer Prevention
Most colorectal cancers begin as small, benign growths called polyps. If detected early, these polyps can be removed before they have a chance to turn into cancer. CT colonography is particularly effective at finding larger polyps and cancers, helping physicians identify issues before symptoms develop. For patients who might avoid traditional colonoscopy, CT colonography offers a more patient-friendly pathway to prevention.
How Iowa Radiology Helps
At Iowa Radiology, CT colonography exams are interpreted by radiologists with advanced training in abdominal imaging. Our team works closely with referring providers to ensure results are not only accurate but also clearly communicated. If an abnormality is found, your provider will discuss next steps, which may include referral for a traditional colonoscopy to remove polyps or confirm findings. By providing precise imaging and collaborative interpretation, we help patients and physicians make informed decisions about care.
Abdominal Imaging at Iowa Radiology
The abdomen is home to many of the body’s most vital organs, including the liver, pancreas, kidneys, and gastrointestinal tract. Imaging plays an essential role in diagnosing a wide range of abdominal conditions, from unexplained pain to chronic disease. Iowa Radiology offers several abdominal imaging options in addition to CT colonography:
- CT Scan. Provides highly detailed cross-sectional images to evaluate conditions such as kidney stones, infections, or tumors.
- MRI. Uses magnetic fields and radio waves for detailed imaging of soft tissues, particularly helpful for evaluating the liver, pancreas, and bile ducts.
- Ultrasound. A safe, radiation-free tool often used for gallbladder disease, liver abnormalities, or abdominal pain.
- DEXA Scan: While primarily used for bone density, this technology can also measure body composition, giving insights into fat distribution and muscle mass.
Patient Comfort and Safety
We recognize that imaging can feel intimidating. At Iowa Radiology, we prioritize patient comfort and safety at every step. CT colonography and other abdominal exams are performed with advanced technology designed to minimize radiation exposure while maintaining the highest image quality. Our technologists explain the process clearly before each scan, helping patients feel more at ease.
The Iowa Radiology Difference
- Expertise in Abdominal Imaging. Abdominal imaging exams are interpreted by radiologists with focused training in gastrointestinal and body imaging.
- Collaborative Care. We work closely with primary care physicians, gastroenterologists, and oncologists to ensure imaging results lead to timely, appropriate follow-up.
- Insight Beyond Imaging. Our role extends beyond producing images. We provide clarity that guides care, helping patients and providers make the best decisions together.
Taking the Next Step in Screening
If you’re 45 or older and haven’t had a colorectal cancer screening, or if you’ve put off traditional colonoscopy, CT colonography may be the right choice for you. Talk with your provider about your screening options and ask for a referral to Iowa Radiology. With advanced imaging and a collaborative approach, we’re here to help you take proactive steps toward better health.
