The Dubai Health Authority to adopt a systematic approach in recording, observing, and controlling CT dose
It seems like Dubai may have the way to effectively reduce radiation dosage and that’s through monitoring. Due to the fact that Dubai has a CT scan rate that has nearly doubled over the past five years. According to an article in auntminnie.com it was stated that “During the past five years, the number of CT studies has doubled at Dubai Health Authority hospitals, and this situation — along with patient overdoses and clinical radiation injuries reported internationally in recent years — prompted the Dubai Health Authority to adopt a systematic approach in recording, observing, and controlling CT dose.”
This study comes about around the same time that the UN released its findings with regards to radiations effects on children as opposed to adults. The key was not reduction so much as monitoring of image quality as the radiation reduction took place. It was stated that “Steps to reduce radiation dose were taken and image quality was monitored. The effects were monitored through change in average DLP on a monthly basis and with respect to third-quartile values, which are used to indicate abnormally high doses on a local, national, or regional scale. Sites in the third quartile represent the 75% of hospitals/x-ray rooms that are giving patients doses below the reference value.” This sort of news does bring to mind how the market is likely to be affected.
Manufacturers are creating hybrid modalities, opportunities are opening up for used and refurbished modality sales and service. The reduction of dosages may make the market open more or may not make things different at all. The market is currently at a height with a projected future value of 30 billion dollars and the growth is only expected to increase with new technologies.
The ability to monitor radiation and use the right amount without overdoing it means a lot in terms of what a physician can tell a patient. Statistics have shown that:
- Exposure to radiation is responsible for a high number of cancer cases.
- Radiation affects patients differently.
- Radiation dosages have a negative effect on children as opposed to adults.
- Radiation is a major concern in imaging.

The issue of radiation will always be present because radiation is a necessity. The idea of actually being able to explain that radiation dosages are far less of a factor is a big plus all around. This simple improvement serves as an aid to physicians and the market in general. Yes, there is still the need for shielding, dealing with authorities and ensuring maintenance but those concerns would lessen just a bit, making the market less restrictive.
It was stated that “Patient doses were managed through automatic tube current modulation, pediatric low-dose protocols, increasing the noise index while maintaining image quality, lowering kV for children, in particular, adjusting gantry rotation speed on certain examinations, reducing scan length to the minimum needed to obtain the required clinical information, and improving awareness of the acceptability of images with some noise.” The dosage protocols for children being lowered and the production of an effective image is something that’s likely to peak the interests of other facilities at different levels.
While this is an initial study if other studies prove that monitoring is the answer to the radiation equation chances are that there will be an interest from other practitioners wanting to expand into the diagnostic imaging sector. The radiation issue is always a concern to people only because it may be a deterrent. The future and further studies can only tell what’s going to happen from here on out.
