Something caught my attention while clearing my gmail account. One article publised in medscape discussing about imaging xrays causes cancer. Upon reading the article, the radiologist is discussing on the radiation dose given to patient via CT scans. In his opinions, the multislices CT scans is causing more harm to the patients and suggests that we should consider more of MRI procedures rather than CT scans. However, i am not very sure of the facts as has not personally measured the dose rate generated by CT scans. Of course, as radiation workers, we do our best to give the lowest possible dose and not compromising the image diagnostic quality. Sometimes i wonder with the new developed technology such as CR, are we reducing patient dose or are we increasing it as image quality differs between the conventional and CR. But with CR, the repeats rates are greatly reduced as we could still adjust lattitude level to get the images required even with wrong exposure factors. And with the help of the engineers, maybe they could find a way to reduce patient dose even further for CT scanners. Never doubt the advancement of the technology.

i was having fun in Operation Theatre these two days. It is really different from the world outside. i still have to master many techniques in order to be competent to work solo in OT. The first case i did went well except i was not very sure why the images appeared so dark. The second case i fumbled as i could not seem to be able to get the toe in the centre of the image and the images appeared even worse than the first time. Was it because i released the exposure button later than required that result in poor quality image. My senior said could be the tube not my problem. He would check on the tube. If nothing is wrong, then it will be my problem. (hmm have to figure that out soon). The third case i used another machine which was indeed easy to maneovre and produced nicer images. Also did my first trauma OT today. My senior is so precised in the positioning of the II, only required slight adjustment then could get the region of interest in already. Dunno when then i could do that manz... ..... Before i went in OT, i thought i would have problems with the ii machines, they are not very easy to handle. The old machine is not that difficult after getting accustomed to it. The newer machine is slightly easy to push around but i still need to practise the manoevre of the different parts of the C arm in order to be efficient in OT radiography.

Oh that reminds me... i need to start my driving lessons if not i will need to sit for the advance theory again.
