Radiologists are medical doctors who use imaging methodologies to diagnose and manage patients and provide therapeutic options. They do not typically handle the general medical needs of a patient. Although they are fully conversant with diagnostic imaging exams, they typically employ radiological technicians to perform the procedures.
Specializations
Physicians practicing in radiology may specialize in diagnostic radiology, interventional radiology, or radiation oncology.
A diagnostic Radiologist uses X-rays, radionuclides, ultrasound, and electromagnetic radiation to diagnose and treat disease.
An interventional Radiologist combines competence in imaging, image-guided minimally invasive procedures, and periprocedural patient care to diagnose and treat benign and malignant conditions of the thorax, abdomen, pelves, and extremities. Therapies include embolization, angioplasty, stent placement, thrombus management, drainage, and ablation.
Radiation oncologists make medical use of ionizing radiation to damage cancer cells; it stops them from spreading further and helps reduce symptoms or, in some cases, cures the condition entirely.
Sub-Specializations
Both diagnostic and interventional radiologists may opt for further training in sub-specialties such as hospice and palliative medicine, neuroradiology, nuclear radiology, pain medicine, and pediatric radiology. Interventional radiologists have the additional option of specializing in diagnostic (for example, angiogram) or therapeutic interventional radiology (for example, balloon angioplasty/stent).
Recent Developments
Interventional radiology has been elevated from a subspecialty of radiology to a primary medical specialty. By deliberate design, interventional radiology remains a part of radiology; the new programs will reside within radiology departments and report to diagnostic radiology chairs; the new certificate signifies competence in diagnostic and interventional radiology.
At the Forefront of Minimally Invasive Medical Imaging
Since the discovery of the X-ray in 1895, radiology remains one of the most technologically advanced fields in medicine.
Medical imaging procedures include plain film or digital X-ray imaging, magnetic resonance imaging (MRI), computed tomography (CT) scans, and fluoroscopy. Breast imaging, including mammography, breast ultrasound, breast MRI, and digital imaging of the breast, is a much sought-after radiology procedure.
Radiologists make extensive use of nuclear medicine procedures such as positron emission tomography (PET) and single-photon emission computed tomography (SPECT) scans. Imaging of the colon requires virtual CT colonography and barium enema.
At the same time, interventional radiology makes effective use of catheters, and ultrasonography uses high-frequency waves to produce an image for medical analysis. A point to note is that digital imaging technology is increasingly being used by imaging facilities today instead of film.
Striking the Right Balance
Radiologists working in a hospital setting are typically available most of the workday. Most radiology practices provide coverage to the hospital at night on-site or on call. Teleradiology assures that a Radiologist interprets the exams concurrently while reducing the amount of time they spend providing direct night coverage at the hospital.
Many radiology groups rotate coverage, and some Radiologists prefer working nights. Also, some radiology groups work in networks to provide coverage to multiple hospitals to reduce the night-call burden. Radiology remains a good option for physicians seeking to balance the needs of work and personal time.
Teleradiology
Teleradiology refers to the practice of a radiologist interpreting medical images while not physically present in the location where the images are generated. Hospitals, mobile imaging companies, urgent care facilities, and even some private practices utilize teleradiology. The main idea behind the use of teleradiology is that it is expensive to have a radiologist on-site.
A Personal Touch
Many Radiologists have limited contact with patients. A referring physician will order imaging exams, such as MRI or computed tomography (CT), and the Radiologist interprets the results, never having met the patient.
Technological advances have further distanced the Radiologists from interaction with the patient. With the advent of teleradiology, they are now able to view images from remote locations via the Internet or satellite. Including a patient's photo with imaging exam results may enable a more meticulous reading from the Radiologist interpreting the images, as well as a more personal and empathetic approach. A Radiologist can opt for a model of medical practice from among the following alternatives.
Solo Practice
A small staff and a limited patient base usually characterize solo practice without partners or employment affiliations with other practice organizations. It allows the physician to design, grow, and develop their personalized style of medical care.
On the flip side, medical care (such as the need to manage hospital care and weekend coverage for patients) and the entire business enterprise rests on the sole Radiologist. They may need to operate the X-ray equipment and help patients prepare for the radiologic examination, tasks typically handled by radiologic technologists in more extensive facilities. Developing agreements with insurers and documentation for regulations involves considerable work.
Solo practices are often at substantial financial risk due to the costs of doing business, possible lack of referrals, the small patient base, shifting patient allegiances because of insurance issues, income loss caused by illness or vacation, and the extent of the physician’s educational debt.
Suburban or rural areas are often better suited to solo practice because of significant medical needs and less competition from medical resources. Some local hospitals affiliate with and support solo practices (financially or with access to electronic medical records) in maintaining their patient base.
Group Practice
The group practice may comprise single-specialty or multi-specialty entities. The single-specialty practice comprises two or more physicians providing patients with a specific type of care (primary care or a particular sub-specialty practice). Multi-specialty group practices offer various types of medical specialty care under one roof.
Group practices enjoy increased financial security and better control of lifestyle. They may provide more employee benefits than are feasible in a solo practice, though often less than what may be available in organizations that employ physicians.
Group practices usually have the resources to manage the administrative tasks associated with running a practice, allowing the physician to focus more time and energy on patient care. They allow for the distribution of clinical care in the hospital at night and on weekends across a more significant number of people leading to more flexible scheduling than in a solo practice.
However, autonomy and decision-making ability decrease, increasing the risk of conflict around significant practice issues. Larger practices may also tend to become more bureaucratic and policy-driven.
Employed Physician Practice
Physicians may be employed within one of several practice models. Some hospitals may purchase and manage existing solo or group practices or may directly hire physicians to work in their inpatient facility or ambulatory clinics. Health-care corporations may own and run clinics with employed physicians.
Some physician-run groups are structured on an employment model. Group practice is structured more like a corporation that employs clinicians instead of pursuing a more traditional partnership model.
Much of the administrative responsibility of running a practice is shifted to the employing entity, allowing the physicians to focus more on practicing medicine. A baseline level of compensation is usually assured, although productivity demands and incentives may be significant. The organization usually has more resources than solo or independent group practices. There is more reasonable coverage for clinical responsibilities, more efficient control of lifestyle, more robust support services, and further education and training opportunities.
The downside is that physician autonomy may be substantially diminished relative to other practice models. Scheduling and productivity may be beyond the physician’s control; others may develop policies and procedures. There may be less clinical flexibility due to limitations of referrals and facilities based on the employing organization. Serving on committees or participating in other organizational activities may be likely.
Other Types of Medical Practice
Some physicians work as independent contractors in a solo or group practice where the facility and possibly clinical coverage is shared with other physicians or physician groups. It may spread the costs of running a practice and may provide some flexibility in clinical scheduling. On the other hand, there is the loss of a degree of decision-making compared to a solo or small group practice.
Locum tenens (literally “place holder”) is an alternative to more permanent employment. Locum tenens positions are temporary (from a few weeks up to a year) offered by practices, hospitals, or healthcare organizations with an unfilled clinical need. The compensation rate is generally higher than what the permanent position would offer. Locum tenens allow physicians to gauge a specific type of practice or location without committing to long-term employment.
