Draft ICRP Report for Consultation: Radiological
Protection Education and Training for Healthcare Staff and Students
The work of an ICRP Task Group is nearing completion, resulting in a draft ICRP
report addressing radiological protection education and training for healthcare
staff and students. This draft is now available for public consultation (see
link below).
ICRP welcomes comments from individuals or groups. The draft document can be
downloaded, and comments submitted, through the ICRP consultation page.
Comments must be received no later than August 6, 2010.
Dear colleague,
We are pleased to announce that the International Journal of Computer Assisted
Radiology and Surgery (IJCARS) has been accepted for indexing in Medline and
Index Medicus. This news should encourage potential authors who intend to submit
a full paper for CARS 2010 or an abstract with possible extension to full paper
at a later date.
IJCARS began with Volume 1, Number 1 in March 2006 and became eligible for
indexing in Medline by the National Library of Medicine after 3 years of
continuous publication. Our application was approved on the first submission, so
we are grateful to all CARS contributors who have contributed to the journal as
authors, reviewers and active readers. Thank you for making the journal so
strong only 3 years after it was launched.
The quality of the submissions has steadily increased. The reviewers have set
exceptionally high standards by thoroughly and rigorously evaluating each
manuscript. We intend to recognize the exceptional achievements of IJCARS
authors and reviewers in future editorials and at the CARS annual meetings.
The acceptance of IJCARS by Medline for indexing is particularly significant
since the acceptance rate by NLM for new journal applications was only 23% in
2009.
You can remain up-to-date on the content of new journal issues by electing to
receive the IJCARS Table of Contents Alert at the journal's website

I have not seen this book but I know both authors and am
familiar with their earlier edition--which was excellent--and I'm confident this
one wil be also.
FYI - New edition of Medical Effects of Ionizing Radiation is out.

Subject: MEDHP-SEC: Latest representative dosimetry
values in diagnostic radiology and nuclear medicine.
Effective Doses in Radiology and Diagnostic Nuclear Medicine: A Catalog
Fred A. Mettler, Jr, Walter Huda, Terry T. Yoshizumi, and Mahadevappa Mahesh.
Radiology Vol. 248(1): 254-263 July 2008.
Medical uses of radiation have grown very rapidly over the past decade, and, as
of 2007, medical uses represent the largest source of exposure to the U.S.
population. Most physicians have difficulty assessing the magnitude of exposure
or potential risk. Effective dose provides an approximate indicator of potential
detriment from ionizing radiation and should be used as one parameter in
evaluating the appropriateness of examinations involving ionizing radiation. The
purpose of this review is to provide a compilation of effective doses for
radiologic and nuclear medicine procedures.
Standard radiographic examinations have average effective doses that vary by
over a factor of 1000 (0.01-10 mSv). Computed tomographic examinations tend to
be in a more narrow range but have relatively high average effective doses
(approximately 2-20 mSv), and average effective doses for interventional
procedures usually range from 5-70 mSv. Average effective dose for most nuclear
medicine procedures varies between 0.3 and 20 mSv. These doses can be compared
with the average annual effective dose from background radiation of about 3 mSv.

I discovered this while leafing
through the most recent issue of RSNA's Radiographics. As you may know,
Wikipedia is an online encyclopedia that anyone can enter information on.
RadiologyWiki was created to apply the technology and methods of collaborative
authorship to create a dynamic online radiology educational resource. This means
that YOU can enter information onto this website. The difference between the two
websites is that for RadiologyWiki you need to register and login, to insure the
accuracy and source of the information. They do not have a section for oral and
maxillofacial radiology, but you can either enter your info under Neuro, or you
can ask a section be added for oral and maxillofacial radiology. You can find
this website at
www.radiologywiki.org
The same issue of Radiographics also has an MRI physics tutorial for residents,
which may be useful if you are taking the boards.

Inspired by Dr. Underhill's talk on the
cervical spine at last year's meeting, I set out to find some good resources
to help me better understand the cervical spine. I found a great book (that
I picked up from RSNA) called "Imaging of the Cervical Spine in Children" by
Leonard E. Swischuk. It talks about development of the cervical spine,
normal variations, anomalies and trauma among other things. It has beautiful
images, and although it's only about 140 pages long, it's a great reference.
The only thing it's missing in terms of cervical spine is degenerative
changes (which you won't see in children - not any great extent anyway).
This website is also nice for trauma:

If anyone has a nice reference for cervical spine imaging in adults,
especially degenerative changes, please share it with us.

Members might be interested to know about this

le Risque de l'Irradiation ( http://www.euradcom.org/index.html
) 2003 Recommendations of the ECRR details at http://www.euradcom.org/2003/ecrr2003.htm Dental radiology is a very minor player in terms of
population radiation exposure. A recent report from Switzerland has again
found that dental x ray contributes only about 1% of
population exposure from the healing arts. (Aroua A et al, Health Physics 83:46-55, 2002.) Since the healing arts in toto contribute
only about one sixth of total population exposure in the US, and probably less in other countries, then the role of
dentistry in total radiation exposure is really minute. (Supplied by Julian Gibbs, July 2002)

in the removal of salivary calculi. Radiol 214:139-142, Jan 2000. We recently created some web-based educational material regarding
the modern management of caries lesions. In particular we wanted to stress the
potential for non-cavitated lesions to be able to remineralize, reducing the
need for placing a restoration. Although there are many web sites with caries
educational material which describe the caries process, most describe it as
a linear process of continual demineralization, or if remineralization is mentioned
it does not describe the potential for avoiding restorations. Our presentation
is entitled "How to heal tooth decay and avoid fillings" and has been
designed for the general public, health educators, students, dentists, and physicians. A very interesting paper on this subject was published in
Physics Today, September 1999. It was written by Zbigniew Jawarowski, a member
of UNSCEAR and a prominent scientist. It expresses a new sentiment that is gaining
popularity: that our existing standards for radiation protection may be more
stringent than the data justify. Nasel et al: Osteometry of the mandible performed using dental MR imaging. Am

The paper presents a comparison of measurements of mandibular dimensions, as
for implant planning, using CT, MR, and direct measurement. No significant differences
are found, despite the known distortions from magnetic susceptibility artifact.
The authors conclude that MR may be used for dental imaging. The term "dental
MR" merely means using MRI for dental purposes--not a special machine or
such.
