Mesothelioma Diagnosis: X-Ray Imaging
X-rays are the oldest form of medical imaging.
Discovered in 1895 by the German physicist Wilhelm Rottgen,
x-ray imaging enabled physicians—for the first time—to
diagnose health- and medical-related problems in the
body’s interior spaces in a non-invasive manner. The
creation of x-ray imaging, as well as the technologies
developed in its wake, truly revolutionized the manner in
which diseases and other conditions could be identified and
treated. Rottgen received the first Nobel Prize in Physics
for his work in discovering and systematically studying
x-rays.
How X-Rays Work
X-rays are a form of electromagnetic energy. They operate
outside of the spectrum of direct human perception, but have
applications for a variety of human pursuits, as well as a
number of possible effects on human tissues. X-rays are
generated by specific tools and the energy emanated from
these tools “passes through” some types of objects and is
absorbed by others. X-ray imaging exploits the manner in
which this energy is absorbed and/or passed through a body
and when it is applied for medical purposes, x-rays are able
to visualize the internal structures of specific parts of
the human body. X-rays are especially good at imaging bone
and similar structures, but they are also able to image
certain kinds of soft tissues as well. For example, chest
x-rays may be able to identify pleural effusions or certain
types of lung cancer in some patients, while an abdominal
x-ray may visualize ascites or a related peritoneal
disorder.
X-Rays and
Mesothelioma Diagnosis
However, as useful as they for any number of other
purposes, x-rays are not helpful for directly imaging
malignant mesothelioma. X-rays do not have enough soft
tissue resolution to properly image pleural surfaces,
so they are not able to differentiate between normal and malignant
pleural tissues in the same way that CT or MRI can. X-rays
may be show an effusion, but they cannot show the actual
malignancy.
Risks
X-rays, like all technologies utilizing ionizing
radiation, can have serious effects on human tissues, so
precautions must be taken to reduce the radiation burden on
tissues under study. The areas in which the x-rays are
directly applied must have limited exposure windows and
those tissues not under study should be properly shielded
from the radiation of the procedure.
