No one likes thinking about colon cancer. But it’s the second leading cause of cancer-related deaths in the U.S.—and far too many people aren’t getting screened early enough to do something about it.


At Life Guard Imaging of Tampa, we believe in prevention, offering a solution that’s faster, gentler, and way less intimidating than what most people picture when they hear the word “colonoscopy.” It’s called CT Colonography, or virtual colonoscopy—and it could be the tool that catches colon cancer early, before symptoms ever show up.

Early Detection Without the Discomfort

CT Colonography uses low-dose CT imaging to generate detailed, 3D views of your colon. Instead of inserting a scope throughout the entire colon under sedation, a virtual colonoscopy requires only a short 2.5-inch tube to gently inflate the colon with air. You’re awake the whole time, without anesthesia. And yes—you can drive yourself home afterward. This makes screening much more accessible for people who:


  • Want a less invasive option.
  • Have medical conditions that make sedation risky.
  • Are avoiding traditional colonoscopy because of fear or discomfort.



In other words, this test makes it easier to take the first step—the one that can lead to earlier diagnosis and better outcomes.

Yes, a CT Colonography Can Detect Signs of Cancer

Virtual colonoscopy is highly effective at spotting:


  • Polyps (those small growths that can become cancerous if left unchecked).
  • Early signs of colorectal cancer.



Every scan is reviewed by a Board-Certified Radiologist, and you receive a clear, comprehensive report you can share with your physician. If something looks concerning, a traditional colonoscopy may still be needed for removal or biopsy. But without this first step, many people would never know there was a concern in the first place.


That’s why we always say: It’s not either/or. It’s both/and. CT colonography is an incredibly useful tool that complements—not replaces—ongoing care from your doctor.


We know fear of discomfort or sedation keeps a lot of people from getting screened on time. That delay can be dangerous. The earlier colon cancer is detected, the more treatable it is. But when screenings are avoided year after year, small polyps can silently grow into something much more serious. CT colonography respects your time, your comfort, and your well-being. It’s fast, accurate, and doesn’t require you to take a whole day off just to recover.

Take the First Step Toward Peace of Mind—Book Your CT Colonography Today

Colon cancer doesn’t always come with symptoms. That’s the scary part. But the good news is—you don’t need to wait for symptoms to do something about it. Schedule your virtual colonoscopy at Life Guard Imaging in Tampa today. Call (813) 576-3526 to book your scan and take control of your health in a way that fits your life.

Our Values: Why Preventative Screening & Medical Imaging Matters So Much to Us

3 December 2025
For most people, work is just work. It’s a paycheck and even a way to get through the day. For us, Life Guard Imaging is personal. We’re here because of a loss—a loss that shouldn’t have happened. A loss that changed everything—one that could have been prevented with preventative medical imaging, the very tool we now use to help others avoid the same fate. Our founder, Frankie Maldonado, lost his father nearly 25 years ago to pancreatic cancer. A disease that, if caught earlier, might not have taken him so soon. His father—a doctor himself—spent his life saving others, yet when it was his turn, the technology available at the time missed the signs. It wasn’t because he didn’t seek care. It wasn’t because he didn’t take his health seriously. It was because the right tools didn’t exist for early detection. So, we created Life Guard Imaging to change that.

Less-Invasive, Just as Effective: Are Virtual Colonoscopies as Effective as Regular Ones?

2 December 2025
No one gets excited about scheduling a colonoscopy, but when it comes to colorectal cancer, catching it early can be life-saving. And for many people, the fear of discomfort or anesthesia is enough to delay or avoid traditional screening altogether. A Virtual Colonoscopy from Life Guard Imaging in Phoenix can truly be a life-saver in these situations. It’s a less invasive, highly effective alternative that gives you critical answers—without the stress.

Osteoporosis and Bone Density Scans: What Your Score Means

2 December 2025
You don’t feel your bones getting weaker. You don’t hear it happening. Unfortunately, there’s really no warning sign. Osteoporosis is silently affecting millions of people—often without a single symptom until a fracture occurs. And by then, the damage is already done. The best time to act is before that happens. And a bone density scan in Tampa is the first step. Here’s what to expect, and what your score means.

What Can Chest CT Scans Show That X-Rays Can’t?

2 December 2025
You go in with a cough. The doctor orders a chest X-ray. It comes back “clear.” You’re relieved—until the symptoms stick around. Sound familiar? X-rays have been a go-to diagnostic tool for decades. And they’re great—for some things. But when it comes to catching serious conditions early, a chest CT scan can reveal what an X-ray simply can’t. At Life Guard Imaging in Phoenix, we offer low-dose CT chest scans designed specifically for preventative care—to give you answers before a problem becomes a diagnosis.

How Often Should Women Get Bone Density Scans?

2 December 2025
Most women don’t think about their bones until something breaks. But by then, it’s already too late. Bone density scans aren’t just for the elderly. They’re one of the smartest, most proactive steps women can take to guard against osteoporosis—a condition that quietly weakens bones and increases the risk of serious fractures. At Life Guard Imaging in Tampa, we’re focused on catching health issues before they catch you. That’s why we offer CT-based bone density scans as part of our larger preventative care approach. It’s not a replacement for your doctor’s advice—but it is a powerful, complementary tool that helps you stay ahead.

How Much Does a Missed Diagnosis Cost? The Case for Early Imaging

2 December 2025
You can’t put a price on peace of mind. But you can tally the cost of a missed diagnosis. And it’s staggering. From mounting hospital bills and delayed treatments to irreversible health damage and missed moments with loved ones—the true cost isn’t just financial or emotional. It’s highly personal, and in many cases, it’s entirely preventable with a simple scan. At Life Guard Imaging in Phoenix, we believe early detection is a strategy. One that complements—not replaces—your primary care. One that gives you a clear picture of your health before symptoms force you into action.

What Illnesses Can Calcium Scoring Detect?

2 December 2025
Just hearing the word “MRI” makes some people sweat. Maybe you’ve been there: sliding into a narrow, loud tunnel, toughing it out. Or maybe you couldn’t do it at all. If claustrophobia has ever kept you from getting the imaging you need—we have good news. CT scans are not as claustrophobic as MRIs. At Life Guard Imaging in Tampa, we use low-dose CT scans that are quick, open, and far less intimidating than traditional MRIs. And when it comes to preventative care, we know that comfort matters just as much as accuracy.

Imaging vs. Traditional Checkups: Why Both Matter

2 December 2025
You make the appointment. You get your blood pressure checked, maybe step on the scale, chat about stress and sleep. If anything seems off, your doctor might order some labs. This is the annual physical—a long-standing staple of responsible healthcare that’s so important. But what if your body is holding onto something your physical exam can’t see? Preventative imaging offers a deeper, clearer look inside your body, complementing your doctor’s work to provide a full picture of your health.

What Does a Coronary Calcium Score Tell You About Heart Health?

2 December 2025
Most people don’t think twice about their heart—until it gives them a reason to. The truth is, heart disease often builds quietly over time, without symptoms, without warning, and without giving you a chance to react. Fortunately, coronary calcium scoring is a powerful tool. It doesn’t wait for symptoms to appear. This scan gives you a clear look at what’s happening inside your arteries today, so you can make smarter choices for tomorrow. At Life Guard Imaging in Phoenix, we believe in catching conditions before they become crises. Our coronary artery calcium scan is one of the most effective first steps in preventative care—and it’s easier than you think.
