CME: New Trends and Technology In Radiology
The medical use of X rays in diagnostic and
interventional radiology remains a rapidly changing field, with a wide range of
applications, procedures and techniques undertaken by the largest single group
of workers occupationally exposed to artificial sources of radiation including radiologists, medical physicists, radiographers and nurses. Similarly members of the public also need to
be protected against radiation while in a radiological facility.
Radiology Dept HUSM have been organising regular CMEs for
radiologists and all radiation worker in medical x-ray for the
annual license requirement. A CME for radiation worker has been conducted at Dewan Persidangan Kampus
Kesihatan HUSM Kubang Kerian Kelantan on 29th September 2018.
The topics which were discussed changes
every year and covering:
- Act 304 & related regulations by Ministry of Health, Malaysia.
- Radiation protection in the use of medical equipment by Medical Physicist.
- Digital radiography by senior radiographer.
- Updates on radiology practice by radiographer.
- X-ray image interpretation by radiologist.
- Clinical updates by medical consultants
And
topics/programmes discussed for the CME 2018 as
below:
The extent of occupational exposure of workers in
radiological facilities depends on the type and complexity of the procedures
employed, typically involving, interventional radiology, general radiography,
computed tomography, fluoroscopy, mammography, and dentistry.
For procedures with fixed installations, the
staff members are generally adequately protected by well-designed shielding
barriers and their occupational exposure is not significant. However workers in close proximity to the
patient, for example physicians/medical officers involved in fluoroscopy including
interventional procedures, may be subject to considerable radiation dose. In
these situations staff dose levels during their working life can in some cases
lead to the occurrence of deterministic effects, such as cataract damage, if
radiation protection actions are not utilised.
The difference between diagnostic radiology and
interventional radiology?
Generally, a diagnostic radiology reads and interprets
radiographs and images after the x-rays have been taken. Diagnostic
radiologists can also performing radiological exams using contrast media to
study certain internal organs and structures during the x-ray imaging.
Interventional
Radiology means, it is any medical procedure that is done under imaging
control. In the past it was fluoroscopy that was used. They used soft radiation
for that, where there was a danger of radiation exposure. But in today’s world
this is no longer popular. Instead MRI and ultrasound techniques have replaced
the older methods.
An Interventional Radiologist utilizes x-ray projections on
fluroscopic and imaging screens to follow the insertion of catheters into
specific veins and arteries to visualize them for any changes such as blockage,
ballooning, malformations, etc. Some interventional radiologists can also
perform fine needle aspiration biopsies, guided by using images from x-rays.
