Not all illnesses make themselves known right away; some produce symptoms like stomach pain before the cause is identified. In a CT scan, there are many pictures taken of the internal organs, blood vessels, bones, and soft tissues. This gives the doctor information about a disease that is not visible in an ordinary x-ray photograph.

However, does that mean that getting a CT scan means finding a disease at an early stage? No, it doesn’t; it all depends on the part of the body that needs to be examined.

What Is a CT Scan, and What Can It Detect?

This imaging modality works on the basis of the X-ray principle to obtain cross-sectional images from various perspectives, sometimes even forming a three-dimensional image.

There are various diseases that can be diagnosed using this imaging modality, such as kidney stones, infections, pancreatitis, trauma, certain cancers, and liver, kidney, pancreatic, and splenic disorders.

It is due to these reasons that CT scans are found to be extremely helpful when there is a need for a whole-body view.

Can a CT Scan Detect Problems Before Symptoms Become Serious?

Sometimes it is. CT can detect abnormalities that have not yet presented any symptoms at all, especially if CT is done for the purpose of screening or diagnosis.

For instance, a low-dose CT is performed to screen lungs for cancer in some high-risk individuals. But CT cannot be used to screen everybody for everything since there are other more suitable tests available for different diseases depending on the patient’s risk profile.

This is why ordering a scan should be justified by a medical necessity.

Can CT Explain Pain Under the Ribs Above the Stomach?

Pain under the ribs above the stomach can have many possible causes, and the location alone does not identify the problem.

Depending upon the symptoms, the physician may need to examine the gallbladder, liver, pancreas, stomach, intestines, kidneys, or other neighboring structures. The role of CT scanning is to diagnose many factors leading to abdominal pain, such as inflammation, infections, stones, injury, and certain tumors.

Nevertheless, CT is not necessarily the primary procedure. For instance, the ultrasound is often a reasonable first imaging procedure in cases of right upper quadrant pain with suspicion of gallbladder disease.

Understanding the Causes of Upper Abdominal Pain

The possible causes of pain in the upper abdomen include various common digestive issues up to those needing immediate medical attention.

The appropriate method for diagnosis will depend upon the type and location of pain, the time period when it occurred, and the presence of accompanying symptoms like fever, vomiting, jaundice, or changes in bowel habits.

The physician may rely on physical examination, laboratory blood tests, ultrasound, CT scan, MRI, or other methods. The choice of imaging method in case of central upper abdominal pain will be dependent on the underlying condition (reflux, gastritis, ulcers, etc.).

Is a CT Scan Safe?

In CT scans, there is the use of ionizing radiation, and therefore, doctors will always assess whether the expected benefits from the test can justify the radiation. Radiation doses vary according to the type of examination, the machine used, and the body part.

Additionally, some CT scans will involve the use of contrast agents to enhance the visibility of certain body parts. Patients are supposed to disclose any medical conditions to the healthcare providers.

When Medical Imaging May Be Needed

Medical imaging may be used to investigate different health concerns, depending on the symptoms, medical history, and clinical question. ViaScan of Las Colinas in Irving, Texas, is one example of a medical imaging provider. Information about the causes of upper abdominal pain can also help explain why different symptoms may require different types of evaluation. 

A patient considering preventive imaging should discuss the purpose, benefits, limitations, and potential risks of a scan with an appropriate healthcare professional. Imaging is most useful when the examination is matched to a specific clinical question.

Conclusion

A CT scan can identify various serious issues and might assist in recognizing some health conditions even when they are still in early stages. Nevertheless, a CT scan is not a universal early detection test and cannot guarantee the discovery of all issues.

If you experience any unusual symptoms related to the abdomen or you feel pain for an unknown reason, consult a doctor regarding the necessary examination.
