CT Scans

My Experience with It

Okay, let’s talk about CT scans.

Because CT, for me, was one of those tests that existed somewhere in the medical atmosphere before I actually understood it.

Like, I knew it was imaging. I knew it was probably related to MRI in some vague way.

I could have told you it was a distant cousin of the MRI.
Not the same person. Not the same personality.

To put it simply, CT was a guy from The Real World omoreso than any medical fixture in my life.

Then I got sick.

And once you get sick-sick, especially liver sick, especially portal hypertension/upper abdominal pain/what-is-my-body-doing-today sick, you start learning the emergency room algorithm whether you wanted to enroll in that class or not.

Upper abdominal pain?
Right upper quadrant pain?
Liver area acting suspicious?

Welcome to the ER. Please enjoy your hospital bracelet.

Now please proceed to the picture machine.

And that is really how CT entered my life. Not as this huge, dramatic, scheduled event like my first MRI. CT felt more like part of the ER choreography. You go in. They ask questions. They poke. They press. They run bloodwork. They look concerned in that specific ER way where they are calm but somehow making you more nervous. And then eventually someone says, “We’re going to get a CT.”

And you are like, okay.
Apparently, we are getting shoved through the picture donut.
Because that is what it feels like.

It is not the MRI.
It is not the giant tube.
It is not the loud magnetic coffin.

It is more like a little circle. A medical hoop. A bubble wand. One of those old-fashioned bubble things you blow through, except instead of making bubbles, it is taking highly detailed pictures of your insides while you lie there wondering how many times you have been scanned in your life without emotionally processing it.

And honestly? CT is fast. That is the thing.

It is fast in a way MRI is absolutely not fast. MRI is an event. MRI has chapters. MRI has a soundtrack. MRI has character development.

CT is like:
Lay down.
Hold still.
Breathe in.
Hold it.
Contrast.
Warmth.
Maybe pee?
Done.

And yes, the contrast is weird. It can make you feel warm all over. It can give you that very specific, very rude sensation that you have just peed on the table.

But listen.At that point in my life, I had to pee all the time anyway. Diuretics, hello.

So the CT contrast was not exactly introducing a brand-new theme. It was just adding dramatic lighting to an existing urinary subplot.

The first time, or at least the first meaningful time, I do not think I had any grand emotional attachment to it. I was not like, “Wow, this is a major imaging milestone.” I was more like, okay, apparently this is what happens when you have cirrhosis and show up in the ER with upper abdominal pain. They run the labs. They get the scan. They check for bleeding, clots, fluid, inflammation, obstruction, whatever disaster they are trying to rule out before they let you go home or decide you are staying for the hospital sleepover from hell.

And that is the thing about CT: it may become part of your life without feeling ceremonial.

It might just appear.
It might be ordered in the ER.
It might be ordered during a hospital stay.

It might be ordered by a transplant center because they want a sharper look at your blood vessels, shunts, portal vein flow, varices, anatomy, or whatever vascular chaos your body has decided to audition that season.

For me, I do have shunts that get watched. So now CT is not just an ER thing. It can also be a “we need to look at the vascular situation” thing. A transplant-center thing. A “let’s see what the architecture is doing” thing.

Which sounds very calm when I say it like that.
Architecture.
Vascular changes.
Shunts.

But really, it is your body building side roads because the main highway is a traffic disaster.
Portal hypertension is not subtle. It does not simply inconvenience the system. It starts rerouting blood like a drunk city planner with a clipboard.
So yes, a CT can be part of that monitoring.

It can help doctors see blood vessels, liver structure, spleen size, fluid, lesions, masses, clots, and emergency problems quickly. It can give them a fast, detailed look when they do not have time for the full MRI production.

But from the patient side, I want you to know this:

CT is not that scary.
It sounds scarier than it feels.
It feels medical, yes.
It feels serious, yes.
You may have an IV.
You may get contrast.
You may feel warm.

You may briefly think, “Did I just pee myself?” and then remember that every person who has ever had contrast has probably had the same exact existential bathroom moment.

But it is quick.
It is usually painless.
It is not a tube in the MRI sense.
It is not 45 minutes of mechanical Berlin grunge.
It is not a spiritual endurance contest.

It is more like a very fast pass through the medical bubble hoop while the machine gets what it needs.

And if you are looking back through your records trying to figure out, “Was that a CT or was that an MRI?” check the context.

Was it in the ER?
Was it fast?
Were they trying to rule something out quickly?
Was there abdominal pain, infection concern, bleeding concern, fluid concern, or some sudden hospital drama?

There is a decent chance that was CT.

Not always.
But often.

CT is the fast one.
The ER one.
The “let’s get a look right now” one.
The “we need pictures before the story gets worse” one.

And once you understand that, it becomes less mysterious. Not casual. Not irrelevant. But less mysterious.

For me, CT went from being this vague distant cousin of MRI to being one of the standard tools in the cirrhosis toolbox.

Not my favorite.
Not my enemy.
Just the picture donut.
Fast, bright, clinical, useful.

And sometimes, exactly what they need to see what your liver, vessels, fluid, and shunts are doing before anyone makes the next decision.

What the Procedure Is

A Computed Tomography, or CT, scan is a non-invasive diagnostic imaging procedure that combines a series of X-ray images taken from multiple angles around your body [1]. Advanced computer processing merges these slices to create highly detailed, cross-sectional three-dimensional images of your internal soft tissues, organs, and blood vessels [2].

Why This Procedure May Be Recommended

In the management of advanced liver disease and cirrhosis, standard clinical protocols mandate regular abdominal imaging. A healthcare provider will typically recommend a CT scan to:

Screen for hepatocellular carcinoma, or HCC, which is the primary form of liver cancer that individuals with cirrhosis carry a higher risk of developing [3].

Monitor the physical progression of cirrhosis, allowing doctors to evaluate structural changes, liver shrinking, or surface nodularity [4].

Evaluate portal hypertension complications, such as tracking the exact size of an enlarged spleen or mapping out dangerous varices, or swollen veins, in the abdomen [3].

Provide emergency assessments during acute hospital or ER admissions to quickly check for internal bleeding, fluid infection, or sudden organ changes [5].

What Doctors Are Trying to Learn

Physicians use an abdominal CT scan to look directly at the structural anatomy and blood flow dynamics of your liver and surrounding organs [2]. Unlike blood tests that reveal cellular stress or manufacturing drops, imaging shows the physical damage [4].

Hepatologists are trying to identify any abnormal tissue nodules or lesions early, when they are small and highly treatable [3]. Furthermore, by using an injected contrast dye, doctors track the exact speed at which blood flows into the liver via the hepatic artery and drains through the portal vein [1]. This blood-flow mapping helps transplant centers evaluate vascular health and accurately judge the severity of portal hypertension [3].

How to Prepare

An abdominal CT scan requires specific preparation steps to ensure the internal images are sharp and clear:

Fasting Requirements: You will generally be instructed to fast, meaning no food or liquids except water, for 2 to 4 hours prior to the scan to ensure your stomach and bowels are empty [5].

Metal and Clothing: Wear loose, comfortable clothing and be prepared to remove all metal objects, jewelry, zippers, or underwire bras, as metal severely distorts X-ray images [1].

Kidney Function Checks: Because contrast dye is cleared through your urinary system, your doctor will run a quick blood test, like creatinine, beforehand to ensure your kidneys are healthy enough to filter the fluid [2].

What Happens During It

The procedure takes place in a dedicated imaging suite and is remarkably fast [5]. A nurse will place a standard intravenous, or IV, line in your arm to deliver the contrast dye [1]. You will lie flat on a motorized table that slides smoothly into the center of a large, doughnut-shaped CT scanner [5].

As the scanner rotates around you, the machine will play automated voice commands telling you exactly when to breathe in, hold your breath, and breathe normally to keep your organs from moving [2]. When the contrast dye is injected through your IV, you will feel a sudden, intense wave of warmth spread through your chest and body, often accompanied by a metallic taste in your mouth and a strange sensation that makes you feel like you are wetting yourself [1]. This feeling is completely harmless and fades in less than a minute. The active scanning is usually finished in 5 to 10 minutes.

What Happens After It

Once the scan is complete, the table slides out, the IV line is removed, and you are free to sit up [5]. There is no recovery period or sedation involved, meaning you can drive yourself home immediately, eat a regular meal, and go about your day [2]. You will be advised to drink plenty of water over the next 24 hours to help your kidneys quickly flush the remaining contrast dye out of your system [1].

Risks and What to Watch For

A CT scan is a highly controlled, safe clinical procedure [1]. Potential side effects and risks are minimal and include:

Radiation Exposure: CT scans use X-rays, meaning they expose you to a small, calculated dose of ionizing radiation [5]. In cirrhosis, the vital medical benefit of catching liver cancer early heavily outweighs this minimal risk [3].

Contrast Reactions: Some individuals may experience mild nausea or a localized itch from the dye [2].

Signs to watch for: Severe allergic reactions to contrast are very rare. However, contact your doctor immediately if you develop hives, swelling in your throat, wheezing, or shortness of breath after leaving the clinic [5].

What Results May Mean

A specialized medical doctor called a radiologist will interpret the cross-sectional images and send a formal text report to your hepatologist [5].

A Normal Report

This indicates that your liver size is stable, the organ contours appear regular, blood vessels are open, and there are no suspicious focal masses or lesions detected [2].

Cirrhotic Structural Findings

The report may describe a “nodular or coarse liver surface,” an enlarged caudate lobe, or fluid accumulation, called ascites, which are all standard structural hallmarks of advanced liver disease [4].

Vascular Stating

Findings like an enlarged portal vein or prominent collateral vessels tell your care team that portal hypertension is active and requires continued medical management [3].

Focal Lesions

If a nodule is found, the radiologist will grade it using a standard system called LI-RADS, or Liver Imaging Reporting and Data System, to tell your doctor whether the spot is a benign scar or requires a follow-up MRI or biopsy [3].

Questions to Ask Your Doctor

To help build your personal tracking records and gain clarity at your next follow-up appointment, consider asking your doctor these questions:

What did the radiologist’s report state regarding the overall structure, size, and surface appearance of my liver today?

Were there any focal lesions or nodules detected on this scan, and if so, what was their specific LI-RADS grading?

Does this CT scan show any new or worsening signs of portal hypertension, such as an increase in spleen size or the development of abdominal varices?

Given my personal health plan, are we keeping my screening schedule strictly on CT scans, or are we rotating between ultrasound and MRI next time?

When is the optimal time for us to schedule my next routine surveillance scan to ensure we are staying completely ahead of any changes?
