Article Review (2): Emerging Clinical Applications of CT

Article summary written by Shyam Venka Thimaiah for discussion on 9/29/16:

Paper: Liguori C, Frauenfelder G, Massaroni C et al. Emerging Clinical Applications of Computed Tomography. Medical Devices: Evidence and Research 2015; 8: 265-278.

This research article discusses the development of CT from its early development as an offshoot of X-ray imaging research to its development in medical technologies. The authors explain in detail the physics behind X-ray attenuation, measurement, image processing, and major hardware components of CT imaging. This article further discusses several types of CT scans which include: MDCT, CT, and DECT along with the wide variety of current medical applications (ex:DECT imaging of the abdomen) that involve these different types of CT. Finally, a discussion of the future use and current research of CT is mentioned (such as CT thermometry) with hope that these applications will enhance the performance of medical procedures, improve accuracy of medical tests, and increase overall patient safety.

  1. Today, the class discussed the article and asked some important questions. The first question asked was what was the relation between X-ray and CT? The class mentioned the major fact that both X-ray and CT use Lambert’s Law to determine the relationship between attenuation and the intensity. We briefly also talked about the developments over time with CT, including the ability to proliferate the x-rays in a cone
    (Second generation CT) which allow for much faster image processing. We also discussed the difference between MDCT and DECT, highlighting the fact that DECT is taken at two energy levels where both images can be compared for a more thorough picture of the cross section. in question. We briefly discussed how DECT can be used to capture a CT image for different parts of the body (ex: Kidney). We then talked about the concept of CT thermometry. We discussed that thermometry was a noninvasive diagnostic procedure which can monitor thermal cellular heating, which we discussed can be useful to perhaps avoid the issue of MRI metal heating that can occur. We finally discussed about the future of CT, stating that there could be developments in personalized CT, to the point more accurate images for a patient with minimal radiation could be achieved.
