When you walk into the emergency room with troubling symptoms, you may wonder what tests are needed. Should you be getting an EKG for your chest pain? An ultrasound for your abdominal discomfort? A CT scan for that intense headache?
Knowing what types of imaging are available and when they’re typically used can help you feel more informed during an ER visit. While doctors will determine what’s clinically necessary, it’s okay to ask questions, and sometimes, even advocate for specific testing based on your symptoms. Understanding how imaging decisions are made, and knowing what to ask, can help you feel more empowered.
EKG (Electrocardiogram): For Chest Pain and More
An EKG is a quick, non-invasive test that records the electrical activity of your heart. It’s often one of the first tools used when patients arrive with:
- Chest pain or pressure
- A history of heart disease
- Shortness of breath
- Dizziness or fainting
- Irregular heartbeat or palpitations
- High blood pressure or known heart disease
An EKG can detect arrhythmias, heart attacks (past or current), and other cardiac issues. An EKG only takes a few minutes, but can detect life-threatening issues like heart attacks and arrhythmias early. If you’re having chest pain that radiates to your arm or jaw, or if you feel like your heart is racing or skipping beats, it’s appropriate to ask whether an EKG is being performed.
Ask for an EKG if you experience:
- Sudden chest pain or tightness
- A racing or pounding heartbeat
- Unexplained shortness of breath
- Lightheadedness or unexplained fainting
CT Scan (Computed Tomography): For the Unexpected
A CT scan uses X-rays and computer imaging to provide detailed pictures of organs, bones, and tissues. It’s often used when doctors need a quick, high-resolution look inside the body.
Common reasons for a CT scan include:
- Head injuries or unexplained headaches
- Abdominal pain with unclear cause
- Signs of stroke (numbness, slurred speech, confusion)
- Chest pain not explained by EKG or X-ray
- Trauma from accidents or falls
- Suspected blood clots (e.g., in lungs or legs)
- Unexplained swelling or severe back pain
CT scans are especially useful in emergencies because they can detect bleeding, blockages, organ damage, or internal injuries quickly.
Ask about a CT scan if you have:
- Head trauma or confusion after a fall
- Sudden, severe abdominal pain
- One-sided weakness, facial drooping, or trouble speaking
- Persistent nausea with intense pain or bloating
- Severe back pain after injury
Ultrasound: For Soft Tissue and Internal Bleeding
Ultrasound uses sound waves to create images of soft tissues. It’s often used in emergency settings to examine the abdomen, heart, and reproductive organs. It’s safe, fast, and radiation-free.
Ultrasounds are commonly used for:
- Abdominal pain (especially in the upper right or lower abdomen)
- Suspected gallstones, kidney stones, or appendicitis
- Pregnancy complications or ectopic pregnancy
- Severe lower abdominal pain with a missed period
- Unexplained pelvic pain or heavy bleeding
- Suspected blood clots (in legs or arms)
- Evaluation of the heart (echocardiogram)
- Guidance for procedures like fluid drainage or abscess evaluation
While ultrasounds are not always the first test ordered, they can be essential in confirming or ruling out several conditions.
Ask about an ultrasound if you have:
- Right upper abdominal pain after eating
- You’ve had unexplained fainting with abdominal or pelvic pain
- Pelvic pain with bleeding during or after pregnancy
- Leg swelling with tenderness (possible clot)
- Sudden testicular or ovarian pain
- A history of gallbladder or kidney issues with new pain
Let the Symptoms Guide the Test
You don’t need to know which test you need before arriving at the ER. The medical team will evaluate your vital signs, symptoms, and history to determine the most appropriate testing. Still, understanding how symptoms connect to imaging can help you feel more confident in asking questions or clarifying the care plan.
- Chest symptoms → Start with EKG and possibly chest X-ray or CT
- Neurological symptoms → CT scan to rule out stroke or bleeding
- Abdominal symptoms → Ultrasound or CT, depending on location and severity
- Injuries or trauma → CT scan to rule out fractures or internal bleeding
- Pelvic pain → Ultrasound, especially for pregnancy concerns
It’s Okay to Speak Up
In a stressful emergency situation, it can be hard to process everything that’s happening. If you feel unsure or think something might be missed, don’t hesitate to speak up. Saying something like “Would an ultrasound help confirm what’s going on?” or “Is a CT scan appropriate based on these symptoms?” is completely reasonable.
You are your own best advocate. And while doctors make decisions based on clinical experience and urgency, informed patients help ensure nothing gets overlooked. In many emergencies, imaging is the turning point that allows treatment to begin. Don’t hesitate to ask what tests are being used and why.
