erectile CT scan preparation

Overview

An erectile CT scan is an imaging test that takes detailed cross-sectional pictures of the penis and nearby structures while the penis is erect (hard). Before the scan, you receive a short-acting medication to create an erection. This helps the doctor see the tissues more clearly and diagnose problems such as scar tissue, blood vessel issues, injury, or other causes of erectile dysfunction.

This scan is not a routine test for every man with erection problems. It is used in certain situations, such as a recent penile injury or a suspected structural issue, when other tests have not given enough information.

It affects men who are being evaluated for erectile dysfunction, penile curvature, suspected penile fracture, or other structural problems of the penis. It is rarely done in boys or adolescents.

Symptoms

Common symptoms

• Trouble getting or keeping an erection
• Pain or discomfort during an erection
• Abnormal bending or curvature of the penis
• Swelling or bruising after an injury

Symptoms in children

• This scan is very uncommon in children. If needed, it is usually for a rare congenital (present from birth) condition or after a trauma. Symptoms might include visible penile swelling, pain, or unusual genital appearance.

Symptoms in older adults

• In older adults, the need for an erectile CT scan is often linked to age-related blood vessel disease. Symptoms may include gradual loss of erection hardness, reduced morning erections, or erectile dysfunction that worsens over time.

Causes

Main causes

• Vascular problems: narrow or leaky blood vessels reduce blood flow to the penis
• Trauma or injury to the penis
• Plaque or scar tissue forming inside the penis, which can cause curvature
• Nerve damage, which can result from surgery, diabetes, or spinal cord injury
• Psychological factors, such as anxiety or stress, that can affect erections

Risk factors

• High blood pressure, diabetes, or high cholesterol
• Smoking or heavy alcohol use
• History of pelvic surgery or radiation therapy
• Getting older
• Certain prescription medicines used for other conditions

When to see a doctor

See a doctor urgently if:

• If you experience sudden painful erection or penile injury, seek urgent care.
• If you notice blood in your urine or severe pelvic pain, contact your local emergency or same-day care service.

Book a routine appointment if:

• If you have persistent erection problems, pain with erections, or notice an unusual curve, make a routine appointment with your doctor.
• If you are scheduled for an erectile CT scan, ask your doctor what to expect and how to prepare.

Diagnosis

An erectile CT scan is one imaging tool your doctor may use to see the internal structure of the penis. It is usually combined with a clinical history, physical exam, and sometimes blood tests or ultrasound before this scan is ordered.

Tests that may be done

• Physical examination of the penis and testicles to check for tenderness, lumps, or curvature
• Blood tests to check for diabetes, hormone levels, and cholesterol
• Ultrasound with blood flow measurements to assess circulation
• Erectile CT scan, which uses X-rays to create detailed images while the penis is erect

What to expect at your appointment

You will change into a hospital gown and lie on a scanning table. A doctor or nurse will give you a small injection or insert a pellet into the penis to produce an erection. This may feel unusual or slightly uncomfortable but should not be painful. Then the table slides into the CT scanner, and you are asked to lie still and hold your breath for a few short seconds at a time. The whole process usually takes under an hour. After the scan, the erection should go away on its own, and you can go home unless your doctor advises otherwise.

Treatment

The treatment after an erectile CT scan depends on the specific problem found. Management options can include lifestyle changes, medications, medical devices, or surgery. Your healthcare team will explain the findings and work with you to choose the best plan.

Self-care at home

• Keep follow-up appointments and share your CT results with your doctor.
• Maintain a healthy lifestyle, including regular exercise and a balanced diet.
• Avoid smoking and limit alcohol.
• Manage stress and talk openly with your partner about your concerns.
• If you were given an injection to create an erection during the scan, contact your doctor if the erection lasts longer than 4 hours.

Medical treatments

Depending on the diagnosis, your doctor may discuss treatment options such as medications that help improve blood flow to the penis, vacuum devices that create an erection by drawing blood into the penis, or other therapies. Always ask your doctor about the benefits and risks of any medicine, and never stop or start a medication without medical guidance.

When is surgery considered?

Surgery may be considered if there is a penile fracture, severe curvature that makes sex uncomfortable, or if other treatments have not helped. Your doctor and a urology specialist will discuss the options and the expected recovery process.

Living with this condition

Living with erectile problems can be challenging, but many men find ways to adapt and maintain intimacy. Focus on open communication with your partner and your healthcare team. You may also benefit from talking to a counsellor who specialises in sexual health.

Lifestyle tips

• Try to reach or maintain a healthy weight.
• Exercise regularly, at least 30 minutes on most days, with your doctor's okay.
• Limit alcohol and avoid smoking.
• Get enough sleep and find healthy ways to manage stress.
• Monitor your blood pressure and blood sugar if you have diabetes or heart conditions.

Diet and exercise

A heart-healthy diet — rich in vegetables, fruits, whole grains, lean proteins, and healthy fats — is also supportive of sexual health. Regular aerobic exercise, such as brisk walking or swimming, improves blood flow and may help with erectile function.

Mental health and emotional wellbeing

Erectile problems can affect self-esteem, mood, and relationships. Anxiety and depression are common. Remember that this is a medical issue, not a personal failure. Seeking help for your emotional wellbeing is an important part of care.

Prevention

Not all causes of erectile problems are preventable, but adopting a healthy lifestyle can reduce your risk of vascular problems that lead to erectile dysfunction. Protecting your pelvis from injury and managing chronic conditions like diabetes and high blood pressure are helpful steps.

Screening programmes

There is no standard screening test specifically for erectile dysfunction. However, men with heart disease, diabetes, or high blood pressure should have regular check-ups that include assessment of overall vascular health.

Complications

If left untreated

• Unresolved erectile problems can affect quality of life and intimate relationships.
• A missed penile injury or infection can lead to lasting structural damage.
• If priapism (a prolonged painful erection) is not treated quickly, it can cause permanent erectile dysfunction.
• Underlying vascular disease that causes erectile problems may also increase your risk of heart attack or stroke if not managed.

Long-term outlook

The outlook is often very good. Most causes of erectile problems can be diagnosed and treated with modern medicine. Even when surgery is needed, many men regain satisfactory erectile function. The key is to work with a qualified healthcare provider and follow the recommended plan.
