Radiologic technologists are the medical personnel who perform diagnostic imaging examinations and administer radiation therapy treatments. They are educated in anatomy, patient positioning, examination techniques, equipment protocols, radiation safety, radiation protection and basic patient care.
Mining data from millions of patients will allow radiologists to create the complete, detailed patient reports that lead to better, more personalized healthcare.
The essence of medical imaging lies in understanding the relationship between patterns of energy emanating from tissues and the underlying state—healthy or diseased—of those tissues. This fundamental paradigm will not change in the future. However, the way we study biological tissues with different forms of energy and how we draw inference from image data will change continuously at a relentless pace.
From Radiographs to Parametric Imaging For the better part of years, physics was the dominant scientific basis of radiology and X-ray attenuation was the paramount measureable parameter. The richness of measurable parameters has taken medical imaging beyond organ anatomy and pathology into the realms of physiology, pharmacology and cellular and molecular biology.
The scale of measurement has been extended from centimeters and millimeters to encompass micrometers and nanometers.
Taken together these developments are moving radiology into the age of molecular medicine and genomics. Images as Data—Derivation of Additional Parameters Digital images are more than pictures; they are sources of data that contain important information not qualitatively perceptible by human observers.
Hundreds of secondarily derived parameters can be extracted from image data sets by advanced computational methods, such as analysis of tumor textures, that can be empirically linked to different tumor genotypes.
Computationally derived images can depict information from multiple parameters allowing us to see how they relate to each other temporally and spatially.
Going forward, we will still talk about images, but the conceptual key to diagnostic inference will be gaining an understanding either directly or empirically of what each parameter represents and how that parameter is manifest in a given disease process.
Radiation Dose Reduction and Phase Contrast Imaging Improvements in X-ray based imaging in the next decade will result in reductions of radiation doses to the point where the issue will no longer be of discussion or concern.
Phase contrast X-ray imaging is likely to be the next new imaging method to be explored clinically. Compared to attenuation based X-ray imaging, phase contrast has the theoretical potential to reduce doses by to fold or more due to the inherently high contrast it affords.
Predictably, it will take time to achieve these levels of benefit but the underlying physics is favorable—phase shift versus linear attenuation of X-rays in biological tissues will usher in the submillisievert era of CT imaging.
Information and Communication Systems With the Internet, borders have blurred between the concepts of information and communication systems, making access to data and distribution of information faster and more efficient. Mobile and wearable media will accelerate these trends.
Timing of information delivery will be tailored to medical need.
Direct patient access to information will democratize the medical record; all physicians, including radiologists, will need to learn how to craft reports that convey necessary information without unduly alarming patients and be mindful that many patients are not medically literate.
These are unsolved challenges today. Decision support DS systems for referring physicians will be built into the work process for computerized physician order entry CPOE.
DS systems will guide radiologists in their recommendations and reduce wasteful variations in practice. Real-time data-mining during the reporting process will be used to help avoid errors—for example, checking consistent use of right versus left and comparing terms used in the body of the report versus the impression.
Radiology subgroups and the specialty more generally must work together to agree on unambiguous standardized nomenclatures to avoid confusing referring physicians and each other—is it a heart attack or a myocardial infarction, a cyst or an inclusion cyst, a tumor or a mass?
Imaging in the Era of Precision Personalized Medicine The fundamental principle of precision medicine or personalized medicine is a definition of ever smaller, more precise subgroups of patients with similar characteristics who have similar prognoses and are likely to benefit from the same therapies.
Imaging phenotypes are systems for scoring, categorizing and classifying disease processes and their severity. Establishing linkages between genotypes and imaging phenotypes radiogenomics will serve as the foundation for surveillance of disease manifestation—occurrence, location, extent, severity—and discovery of genetic polymorphisms.
Radiologists should begin considering their interpretations in this conceptual framework if we are to take a leadership role in the era of precision medicine as productive, vital members who speak a common language.
Challenges and Opportunities Future developments will certainly entail vastly increased complexity in imaging technology and radiology practice, and the increased educational activities those advancements will require.
On a positive note, the future will bring new capabilities that have even greater medical value.Radiologic technologists perform a variety of important medical imaging tasks in order to detect and diagnose illness.
Healthcare employers around the country are urgently seeking candidates to fill these important jobs. Radiology jobs are available for people with a wide variety of skill and education.
