Understanding the Evolving Role of Radiology in Healthcare

42

As a medical specialty, radiology plays a critical role in the delivery of quality healthcare services. Its origins can be traced back to the early days of basic X-ray image capture. At the same time, the highly technical nature of the field necessitated the introduction of radiologists as clinical specialists.

Radiology helps medical practitioners diagnose a wide variety of diseases. Additionally, the specialty makes it easier to predict patient outcomes and monitor treatment. The imaging modalities involved in the diagnosis of various conditions come with principles of varying complexity.

Over the years, technological advancements have improved the anatomical detail of images and sensitivity of the equipment. As a result, medical experts are taking advantage of the technology to handle functional and quantitative diagnostics. The same applies to ultrastructural diagnostics and molecular medicine.

Advances in digital imaging technology are enabling medical practitioners to leverage additional features to improve quality. With the newer equipment, radiologists can post-process and rapidly share the images with colleagues in any location. 

Radiologists have been working closely with the manufacturers to improve the design and functionality of imaging equipment. 

They helped maximize the clinical effectiveness of devices by contributing to the enhancement of integrated imaging algorithms. Manufacturers also consulted radiologists to ensure the seamless deployment of these technologies in the clinical setting. 

Training

The amount of diagnostic information drawn from imaging equipment increased exponentially thanks to the enhanced image clarity as well as the differentiation of tissues. In most cases, the imaging process does not involve invasive tissue sampling (histology). 

The expanded diagnostic information requires accurate interpretation to enable doctors to make informed choices. On another level, radiologists have discovered that the use of cellular activity and functional evaluation complicates their work. Traditionally, radiology training concentrated on the pathological and anatomical models.

As a result, the specialists found themselves compromised by the limited experience in cell function and physiology. Many experts agree that radiologists need to harness their skills by undergoing relevant training to boost the capacity to handle the new approaches.

In turn, it becomes easier to evaluate clinical aspects more effectively. It comes as no surprise that many training programs in Europe are now focusing on systems and diseases. The approach is aimed at enhancing the capacity of radiologists to handle specific patient care challenges.

These changes to the training programs are helping reposition radiology and their role in healthcare. A marked increase in complexity and workload of examinations have contributed to the radiologist shortage.

On the other hand, some medical institutions are taking advantage of internet access to centralize rapid specialist interpretation of images. Doing so eliminates the need to enlist the services of local radiologists. 

Transformation

The radiology field needs to achieve a delicate balance by performing its traditional role while assuming new functions. It is now common for specialists in the field to handle tasks that were historically the responsibility of clinicians. These new tasks are now the domain of radiology.

Different specialties often share space in clinical services. As such, surgeons usually share operating rooms with colleagues from other specialties. Meanwhile, intensive care units now operate independently as they no longer align with departments like neurology and cardiology.

Radiologists may occasionally use hospital beds following specific procedures. This scenario means that the beds are no longer reserved for individual specialties. Conversely, various clinical specialists are now sharing imaging facilities with radiologists. Images generated in the radiology department are often transmitted and reported remotely.

Other specialists gaining access to the radiology department are usually trained in imaging. In the meantime, new concepts in imaging are developing at a faster rate as the field continues to expand its focus. 

Some of the medical conditions covered by the field include:

  • Multi-morbid aging population
  • Bone dysplasia
  • Pituitary gland
  • Prostate complications
  • Pancreatic neoplasia

The expansion negatively impacts the trainees’ ability to grasp all the available clinical and radiology knowledge. On the upside, a referring doctor can take advantage of a clinical interface that provides a link with the imaging specialist. The radiologist needs to understand the nature of the clinical problem involved. 

However, the radiologist will need to grasp the clinical problem from a wide variety of specialties. Hence, the need to undergo relevant training before enrolling for imaging training. In some cases, the radiologist may have to embark on training in specific clinical specialties to provide value to the referring physician.

Regular with patients promotes the recognition of radiology’s role in the delivery of quality healthcare. However, the role of the radiologist is typically obscured since their work takes place in secondary and tertiary hospitals. The provision of radiology services in primary care is minimal. The requirements are significantly different in primary care as they need generalized services. 

It is common for some countries to assign image interpretation roles to clinical specialists. On the downside, this approach undermines the quality of healthcare services for patients.
