CT scans can detect bone and joint problems, like complex bone fractures and tumors. If you have a condition like cancer, heart disease, emphysema, or liver masses, CT scans can spot it or help doctors see any changes. They show internal injuries and bleeding, such as those caused by a car accident.
Chronic back pain or an injury to the spine are among the most common reasons to have a CT scan. A doctor may also order a spinal CT scan to: Evaluate spinal fractures. Assess the condition of the spine before and after surgical procedures.
A CT scan may be ordered if your doctor suspects you have a tumor or blood clot. These issues could be a symptom of a very serious problem; therefore the sooner they are discovered the better off the patient will be. These scans may also be used to look for signs of an infection or any excess fluid.
Where MRI really excels is showing certain diseases that a CT scan cannot detect. Some cancers, such as prostate cancer, uterine cancer, and certain liver cancers, are pretty much invisible or very hard to detect on a CT scan. Metastases to the bone and brain also show up better on an MRI.
What Types of Cancers Can a CT Scan Detect?

A CT scan of the abdomen and pelvis can help diagnose problems in the bladder, uterus, prostate, liver or bowels. This procedure is typically used to help diagnose the cause of abdominal or pelvic pain.
The abdominal CT scan may show problems with the gallbladder, liver, or pancreas, including: Acute cholecystitis. Alcoholic liver disease. Cholelithiasis.
CT scans show a slice, or cross-section, of the body. The image shows your bones, organs, and soft tissues more clearly than standard x-rays. CT scans can show a tumor's shape, size, and location. They can even show the blood vessels that feed the tumor – all without having to cut into the patient.
Most abdominal CT scans will include a portion of the lung bases, although there may be some exceptions depending on local techniques. Pre-pandemic reports have assessed the value of close examination of the lung bases for clinically significant abnormalities .
A CT scan shows detailed images of any part of the body, including the bones, muscles, fat, organs, and blood vessels. CT scans are more detailed than standard X-rays.
Screening tests for two of the most common forms of cancer involve detailed x-ray images of the chest. Growing evidence suggests that these tests — chest computed tomography (CT) scans and mammograms — may also offer clues about a person's risk of heart disease.
A multidetector CT is a very fast type of CT scanner that can produce high-quality pictures of the beating heart and can detect calcium or blockages in the coronary arteries. An electron beam CT scanner also can show calcium in coronary arteries.
Diagnostic tests for congestive heart failure may include: Resting or exercise electrocardiogram (also known as EKG, ECG, or stress test) Echocardiogram. Computed tomography (CT) scan.
A CT coronary angiogram is used to directly visualise the heart arteries and the fatty deposits (plaques) that can develop within them. This fatty plaques can mean your heart is not getting the blood supply it needs, which can cause chest pain (angina) and heart attacks.
A CT scan can give your physician extensive information about where you may have narrowing in the carotid arteries. For the test, you may also be administered contrast dye, a substance that makes it easier to see the blood vessels.
As a widely used examination method, CT imaging can be used to help detect esophageal cancers (16). Radiologists use the abnormal thickening of the esophageal wall as the diagnostic basis to indicate the occurrence of esophageal cancer, thereby prompting the patient to further endoscopy to verify the diagnosis.
Cardiac MRI "provides the gold standard of cardiac function and anatomy unsurpassed image quality in evaluating heart structure and function in 3-D-quality moving images," Levine tells WebMD. And cardiac MRI "shows us more than echocardiography or an exercise stress test," Steiner adds.
Results of a head-to-head comparison study led by Johns Hopkins researchers show that noninvasive CT scans of the heart's vessels are far better at spotting clogged arteries that can trigger a heart attack than the commonly prescribed exercise stress that most patients with chest pain undergo.
The tests may include:

A CT coronary angiogram can reveal plaque buildup and identify blockages in the arteries, which can lead to a heart attack. Prior to the test, a contrast dye is injected into the arm to make the arteries more visible. The test typically takes 30 minutes to complete.
