Chronic diseases account for most illness, disability and death in the United States, and they are the leading drivers of health care costs. Heart disease and stroke alone killed more than 850,000 Americans in 2024, more than one in four deaths.
Chronic diseases are conditions that persist for a year or more, needing ongoing medical care or limiting daily activities. Three in four American adults already live with at least one, and more than half live with two or more. It builds with age: 60 percent of adults aged 18 to 34, more than 75 percent of those aged 35 to 64, and more than 90 percent of those 65 and older.
Chronic conditions are not always an overnight realization – they often take time to develop and “grow,” making it challenging to catch symptoms of chronic diseases in their early stages.
But what was once seen as a challenging feat is now seen as possible – with a proactive approach, that is.
Follow along as we highlight various chronic conditions that can develop over time and how a full-body scan near you may be the key to early detection.
Heart Disease
Heart disease, also referred to as cardiovascular disease, describes a range of conditions that affect the heart. Heart disease includes any condition that hinders the heart’s ability to supply blood and oxygen to other organs. These conditions may include:
- Coronary artery disease
- Arrhythmias
- Congenital heart defects
- Heart valve disease
- Enlarged heart
Symptoms will vary based on the type of heart disease you are diagnosed with. General symptoms will include chest pain or tightness, shortness of breath, lightheadedness, or fatigue, among others.
Arthritis
Arthritis is a blanket term for more than 100 diseases and conditions affecting the joints, surrounding tissues, and other tendons and ligaments. An arthritis diagnosis refers to the swelling or tenderness of one or more joints, often resulting in joint pain or stiffness that worsens as you age.
Early symptoms of arthritis can be easily overlooked, often presenting as a dull ache or a slight increase in soreness.
Not all arthritis behaves the same way. Inflammatory arthritis such as rheumatoid arthritis can begin damaging joints within the first year or two, and once that damage occurs it generally cannot be reversed, which is why early diagnosis and treatment matter so much. It is diagnosed through your history, a physical examination of your joints, and blood tests including rheumatoid factor and anti-CCP antibodies, with imaging supporting the picture. Osteoarthritis, the most common form, is managed differently, with treatment focused on reducing pain and keeping the joint working. If your joints ache, swell or stiffen, the first step is a conversation with your doctor rather than a scan.
How Each of These Is Actually Caught Early
We are an imaging clinic, so you might expect this section to say a scan is the answer. It is not, and we would rather be useful than promotional.
Heart disease is assessed with tools built for the heart. Coronary artery disease is evaluated through your risk factors and cholesterol, an ECG, a coronary calcium score or CT angiogram, and stress testing. Arrhythmias are electrical rather than structural, so they are found on an ECG or a wearable rhythm monitor. Valve disease needs an echocardiogram, which shows the valves moving in real time and measures flow across them. A whole-body screening MRI is not a cardiac study and does not substitute for any of these.
Arthritis is diagnosed clinically and with blood work, as described above. Anti-CCP antibodies can turn positive before symptoms appear, so the early-detection tool here is a blood test, not a scan.
Diabetes and kidney disease, two more of the biggest contributors to that chronic disease burden, are found through blood and urine tests. An A1C, a fasting glucose, an eGFR and a urine albumin-to-creatinine ratio will tell you far more than any scan, and they are inexpensive and routine. Ask your primary care doctor.
So Where Does a Whole-Body MRI Fit?
In a narrower place than most marketing suggests, but a real one.
Its genuine strengths are soft tissue detail without ionizing radiation, and the incidental detection of structural things nobody was looking for: a mass, a cyst, an aortic aneurysm, or an enlarged heart that warrants a cardiology referral. It also gives you a structural baseline to measure future scans against.
What it does not do is catch the conditions that drive those CDC statistics. Quoting chronic disease mortality figures and then pointing you at a scan would be a non sequitur, and we are not going to make that argument.
It is also worth knowing that scans of healthy people turn up findings that need follow-up and often amount to nothing. We cover that in what incidental findings actually are.
Whole-Body Screening MRI in Charleston
If your routine screening is current, you have talked to your doctor about the blood work above, and you want a broad structural look as well, that is what we offer. Whether you have a genetic predisposition or simply want a baseline, our team will talk it through honestly first.
Schedule an appointment or call us, and we will tell you if a scan is not the right thing for your situation.

Frequently asked questions
What chronic conditions develop over time?
Most of the biggest ones. Heart disease, type 2 diabetes, chronic kidney disease, osteoarthritis and inflammatory arthritis all build gradually, often without symptoms in the early stages. Three in four American adults live with at least one chronic condition and more than half live with two or more, and prevalence climbs with age from 60 percent of adults aged 18 to 34 to more than 90 percent of those 65 and older.
Can a full body MRI detect heart disease?
No, not in any meaningful sense. Coronary artery disease is assessed through risk factors, cholesterol, an ECG, a coronary calcium score or CT angiogram, and stress testing. Arrhythmias are electrical and need an ECG or rhythm monitor. Valve disease needs an echocardiogram to see the valves moving and measure flow. Our scan is not ECG-gated and uses no contrast, so it is not a cardiac study. It may note a grossly enlarged heart as an incidental finding, which is a reason for a cardiology referral rather than a diagnosis.
How is arthritis caught early?
Clinically and with blood work. Rheumatoid arthritis is diagnosed through your history, a joint examination, and tests including rheumatoid factor and anti-CCP antibodies, with imaging supporting the picture. Anti-CCP can turn positive before symptoms appear, so a blood test is the early-detection tool. Early treatment genuinely matters for inflammatory arthritis, because joint damage in the first year or two is generally irreversible. Osteoarthritis is different and has no disease-modifying treatment; management focuses on pain and function.
What tests should I actually ask my doctor for?
For the conditions that drive most chronic disease burden: blood pressure, a lipid panel, an A1C or fasting glucose for diabetes, and an eGFR plus urine albumin-to-creatinine ratio for kidney function. These are inexpensive, routine, and will tell you more about your chronic disease risk than any imaging test.
Where does a whole-body MRI genuinely help?
In a narrower place than most marketing suggests. Its real strengths are soft tissue detail without ionizing radiation, incidental detection of structural findings such as a mass, a cyst or an aortic aneurysm, and a documented baseline to compare future scans against. It does not catch the conditions behind the chronic disease statistics, and we would rather say so than imply otherwise.
