New method for
diagnosing pulmonary diseases in children
Clinic for Children and Young Adults of the
Friedrich-Alexander University of Erlangen and the Siemens
Medical Solutions Group have developed a new method for
diagnosing pulmonary disease in children.
can be examined under an open magnetic resonance
tomograph (MR) without radiation.
A study of 150 young patients confirmed that the
high-resolution images have a diagnostic reliability
equal to that of a radiograph.
Radiographs of the thorax account for a considerable
portion of radiological examinations in paediatrics.
To evaluate the course of a disease, frequent repeat
examinations are necessary, in particular with
pulmonary diseases such as asthma, pneumonia,
tuberculosis and mucoviscidosis.
The fact that the radiation sensitivity of children
is four times higher than that of adults called for
the development of a safe, fast and at the same time
diagnostically highly differentiated alternative to
The low-field MR systems Magnetom Open and Concerto
represent a system class which offers the
performance parameters necessary to solve the
problems existing to date in magnetic resonance
imaging of the lungs.
The low-field MR system Magnetom Open and its
successor Magnetom Concerto, which has a field
strength of 0.2 Tesla, combine the advantages of an
open MR system with the image quality of a
By using powerful gradients these systems achieve
exposure times previously only for high-field
The so-called TrueFisp technology developed by
Siemens provides fast and continuous image
This unique combination provides the radiologist
with high-quality images of the thorax within
While containing the same image information as
radiographs, the images also supply differentiated
The open, patient-friendly C-shape of the system is
particularly suited for use in paediatrics, but also
allows the examination of claustrophobic patients
who were previously unable to undergo MR scans.
The suitability of this new method was successfully
tested on 150 patients in a clinical study.
Dr Thomas Rupprecht, a paediatrician at the Clinic
for Children and Young Adults at Friedrich-Alex-ander
University of Erlangen-Nuremberg, said:
"Tog-ether with Siemens we have succeeded in
developing a method which will establish itself as a
first-line examination method for paediatric
patients with pulmonary diseases."
