Great Ormond Street Hospital opens innovative new imaging centre
15 February 2008
Great Ormond Street Hospital in London, UK, a national
centre of excellence in specialist healthcare for children, has opened a
state-of-the-art medical imaging centre. The new facility has been developed
to provide a high quality diagnostic imaging and interventional treatment
service whilst ensuring comfort for its young patients.
delivers the widest range of specialist care of any children’s hospital in
the UK. Each year it has 150,000 patient visits from children ranging from
premature babies to late teens. The new magnetic resonance (MR) and computed
tomography (CT) Imaging Centre has been equipped with the latest imaging
technologies from Siemens and will perform a vital function in the
investigation, diagnosis and research.
The new technology gives instant
benefits to patients and staff. Modern technology is easy to use and enables
the latest clinical techniques to be offered to patients. This usually means
that less invasive procedures can be provided, which helps to reduce the
anxiety usually experienced by young and unwell children and their parents.
For example, an MRI scanner has been combined in the same room as a
cardiac angiography suite connected by a ‘Myabi’ patient transfer table.
This unique hybrid solution, developed by Siemens in partnership with Great
Ormond Street Hospital, allows two different examinations to be carried out,
one immediately after the other, without needing to re-anaesthetise the
patient. This is especially useful in the research and clinical application
of non-invasive heart surgery using advanced catheterisation techniques.
The Siemens portfolio at Great Ormond Street Hospital includes:
- an independent Magnetom Avanto Cardiac MR unit;
- a MAGNETOM Avanto MR combined with an ‘Artis dBC’ Cardiac Angio
suite incorporating Myabi patient transfer table; and
- a SOMATOM Definition Dual Source CT Scanner.
A ‘Symbia T2’ SPECT/CT Nuclear Medicine Scanner is also due to be
installed shortly. All equipment is connected to a Siemens PACS and
Medcon Cardiac system for fast image archiving and recall.
Siemens because we felt that each element of the equipment was the best on
the market, and that the Avanto MR scanner had the most development
potential,” said Dr. Andrew Taylor, Reader in Cardiovascular Imaging,
Director at the Centre for Cardiovascular MR, Great Ormond Street Hospital.
“Since installation, we have used the combined hybrid MR and Cath Lab to
successfully guide device implantations, increasing patient safety, reducing
x-ray radiation dose and monitoring the effectiveness of the procedures.”
“The Siemens Definition CT scanner provides a unique opportunity to
undertake state-of-the-art cardiac CT in children without the need to use
beta-blockers to slow the heart. We have undertaken 600 cardiac CTs at Great
Ormond Street Hospital in the last three years and hope to utilise the new
scanner to its maximum capacity working closely with physicists to enable
significant radiation burden reduction to all of the children undergoing
head and body CT, as well as cardiothoracic CT,” said D. Catherine Owens,
Consultant Radiologist at Great Ormond Street Hospital.
Definition Dual Source CT Scanner is an innovative solution offering
advanced clinical opportunities and enhanced patient comfort. The speed of
the scan is rapid enough to minimise the need to sedate patients and the
wide opening minimises the feeling of claustrophobia — both important
factors in the treatment of children.
The dual source design uses two
x-ray tubes and two detectors at the same time giving double temporal
resolution, which doubles the speed of scanning for cardiac imaging with
high heart rates. This has great potential for cardiac imaging in children
as the heart can be examined independently of the heart rate and without the
need for beta-blockers.
The unique design also enables new clinical
applications with different energies to gain valuable information to
accurately diagnose and plan the most effective treatment. Furthermore, with
the industry’s highest spatial resolution (0.33mm), fine anatomical details
can be imaged, such as the smallest coronary vessels. Sophisticated dose
modulation technology ensures that all examinations result in high image
quality at the lowest achievable dose.
“Great Ormond Street Hospital is a
recognised centre of excellence for paediatric diagnosis and treatment,”
said Peter Harrison, Director of Imaging & Oncology Systems at Siemens. “We
are delighted to have been involved in the provision of new equipment and in
devising a unique and bespoke MRI and angiography solution. Collectively the
new equipment will extend the provision of care offered to patients and work
towards improving clinical outcomes well into the future.”
opening event was held on 17th January 2008 and involved key hospital
stakeholders. Dr. Jane Collins, Chief Executive of Great Ormond Street
Hospital addressed the guests and assisted Oliver Barlin, a 9 year old
patient, to unveil the commemorative plaque marking the opening of the new
MR & CT Imaging Centre. Oliver had been suffering frequent epileptic fits
caused by a lesion on his brain until explorative MRI examinations were used
to identify his condition and prepare for delicate neurosurgery to remove
the lesion. Oliver is now doing well and is free of seizures.
