The Radiology Department at Children’s Health Ireland (CHI) at Crumlin offers a comprehensive range of diagnostic imaging and interventional cardiology services for children and young people.  We have over 70 members of staff working in Radiology, including Radiographers, Radiology Consultants, Radiology Nurses, Health Care Attendants, and Administrative staff working in the department.  Meet the Consultant Team here.

The tests we offer include ultrasound, nuclear medicine, computerised tomography (CT), magnetic resonance imaging (MRI), general X-rays, fluoroscopy and interventional cardiology (IC).

The department performs approximately 60,580 examinations per year, including approximately 7,400 ultrasounds, 700 fluoroscopic studies, 2,500 CT examinations, 5,400 MRI examinations, 560 nuclear medicine examinations, 43,000 plain radiography cases and 770 interventional cardiology procedures and 250 interventional radiology procedures.

Radiology Equipment

We are equipped with the latest technology, which we have chosen with our paediatric patients in mind.

Diagnostic Imaging

A hospital-wide imaging solution allows clinicians to view radiology examinations from any PC in the hospital. The General Radiology Department comprises two Arcoma Canon Intuition general purpose X-ray Rooms, a Canon Ultimax I fluoroscopy unit, five mobile x- ray units and four mobile fluoroscopy units. We also have an EOS scanner for spinal imaging.

Ultrasound - The Ultrasound Department has one Hitachi Noblus scanner and two Hitachi Preirus scanners.

CT Department - The CT Department is equipped with a 128 slice Phillips Ingenuity Core 128 CT scanner.

MRI Department - The MRI Department has a 1.5T Siemens Avanto scanner.

Nuclear Medicine - The Nuclear Medicine Department is equipped with a GE Discovery Pro 670 Single-photon Emission Computed Tomography (SPECT) - CT scanner.

Interventional Cardiology Department - The Interventional Cardiology Department has a state of the art Hybrid Cardiac Catherisation Laboratory (HCCL) located in the Theatre complex equipped with a bi-plane Siemens Artis Q-Zen.

Tests offered by the Radiology Department

The Radiology Department performs a variety of tests to help with the diagnosis and treatment of a range of conditions. Different types of imaging are appropriate depending on the clinical query and sometimes several modes of imaging are necessary to help diagnose a condition and monitor treatment.
The department offers the following services:

General X-ray

An examination that uses small amounts of radiation to show structures inside the body such as the bones and lungs.

Contrast studies

Diagnostic tests where a contrast dye such as barium, which shows up on X-ray, is swallowed or given through a tube to help outline structures of the body on X-ray. Specific types of contrast study include for example contrast enemas and barium meals.

CT Scanning

A computer system which uses X-rays to take more complex pictures of the internal structures of the body.

MRI Scanning

A scan using a magnetic field rather than X-ray to take pictures of the body.

Nuclear Medicine

An imaging specialty that uses radionuclides (drugs or medicines that contain small doses of radioactivity) to study the structure and functions of the body. Examples of nuclear medicine scans include bone scans and DMSA Scans.


An imaging technique that uses X-rays to obtain real- time moving images of the internal structures of the body. Specific types of fluoroscopy scans include: barium and water soluble gastro-intestinal studies; fistulograms and sinograms; palatal studies and videofluoroscopy studies.


A scan which uses sound waves to take pictures of the body.

Interventional Cardiology

a specialised X-ray study, performed under general anaesthetic, to find out detailed information about the blood vessels of the heart and to treat a variety of complex heart conditions. 

X-rays for Children: Benefits and Risks

On average, 1 in 3 people will develop cancer during their lifetime. X-ray examinations may slightly increase this normal chance of developing cancer later in life. When X-ray examinations are needed for diagnosing an illness or injury in a child, the benefits of the examination always far outweigh the radiation risks.  The radiology staff in our department are trained to ensure that the lowest possible radiation dose is used to obtain a diagnostic image of your child, as part of their medical care.

More detailed information on radiation exposures can be found on our radiation information sheet which can be downloaded from here 

In some cases, imaging can be performed using equipment which does not use X-rays. Such equipment includes magnetic resonance imaging (MRI) and ultrasound.

Protection of the Unborn Child

In cases where X-rays are used to acquire an image of the abdominal area, we are legally obliged to ask any girls over the age of 12 whether there is any chance they might be pregnant. This is to protect any unborn children from receiving an unnecessary exposure to X-rays.

This does not apply for MRI or ultrasound examinations.
