Diagnostic services

Cromwell Hospital and Basinghall Clinic use the very latest technology to perform diagnostic scans and tests.

About our diagnostic services

A wide range of scans are available to cover any diagnostic requirements, from X-ray and bone density scans to MRI, CT, and PET-CT scans, as well as the most up-to-date heart imaging.

Leading edge machines – including ambient MRI scanners that reduce patient stress – are used to provide the best quality imaging and the most comfortable experience for patients.

Tests take place either at the hospital, or at the new Clinical Investigation Centre on Pennant Mews, next to the main hospital building. We also have a wide range of diagnostic equipment at Basinghall Clinic, our outpatient diagnostic centre in the City of London, including MRI, X-ray, mammography, and ultrasound.

Results are usually provided within 24 hours. If the tests reveal a need for further scans or treatment, patients can be referred immediately on to one of the hospital's specialists.

Diagnostic services we offer

All diagnostics are available at Cromwell Hospital, while many are also available at Basinghall Clinic.

A DEXA (dual energy X-ray absorbtiometry) scan uses X-ray and a computer to measure bone density.

Your doctor may recommend a bone density scan if you have fractured a bone after only a minor fall or bump, or you are in a high-risk group for osteoporosis.

A computed tomography (CT) scan uses X-ray and computer software to create detailed images of inside your body. It is sometimes also known as a CAT scan.

CT scans are used to diagnose and monitor many different conditions, including cancer, damage to bones, and stroke.

A health assessment is a series of tests used to review your overall health. It can help you better manage your health in the future.

We offer several different types of health assessments for men and women using the state-of-the-art diagnostic and imaging technology.

Mammography, also known as breast screening or breast X-ray, is used to detect changes that have occurred in a woman’s breast.

A mammogram is produced by passing a type of radiation through the body, in the same way as with other X-rays. The image that is produced from breast screening can show up changes in breast tissue.

Magnetic resonance imaging (MRI) is a type of scan that uses magnets and radio waves to produce images of the inside of your body. It is used to help monitor and diagnose many different medical conditions.

At Cromwell Hospital, our MRI scanners can carry out a full body scan 30% faster than most machines. You can also choose your own lighting, wall images, and music to help you feel relaxed and comfortable during the procedure.

An MRI with contrast uses an injection of a contrast agent (dye) to help highlight your blood vessels, organs, and soft tissues in greater detail.

There are two parts to this type of scan – a PET scan and a CT scan. Both are carried out at the same time.

A PET scan shows how the tissues and organs inside your body are working, while a CT scan uses X-ray and a computer to create a detailed 3D picture.

Ultrasound scans use high frequency sound waves to create images of internal organs such as the stomach, heart, tendons, muscles, joints, and blood vessels.

X-ray scans produce detailed images of the body using a type of harmless radiation, similar to light. They can be used to both diagnose and monitor health conditions.
