COVID-19 Outbreak Negatively Hampered Market Growth Due to Decline in Diagnostic Procedures

The COVID-19 pandemic had both positive and negative impacts on the diagnostic imaging services market. One of the major consequences was that the hospitals and the imaging centers limited the number of procedures conducted. For instance, the total number of CT scan procedures conducted in the U.S. decreased from 92 million in 2019 to 73 million in 2020, with an annual decline of -21.0%. Moreover, major key players in the market, like RadNet, Inc., observed an annual decline of -12.9% in the number of procedures conducted in 2020 for all modalities.

Furthermore, the average cost of these procedures increased in 2020 due to the COVID-19 outbreak. For instance, the cost of CT scans increased from USD 231.0 in 2019 to USD 312.0 in 2020. However, this decline had a short-term negative effect on the market. There will be minimum or no change in the long-term fundamental drivers affecting the demand for diagnostic imaging devices. These factors led to a decline in the number of diagnostic imaging procedures conducted in the U.S., and thus, the diagnostic imaging services witnessed a negative growth in 2020.

Growing Geriatric Population to Augment U.S. Diagnostic Imaging Services Market Growth

With age, the risk of developing diseases rises correspondingly. As per the Centers for Disease Control and Prevention (CDC), nearly 80.0% of the elderly in the U.S. have at least one chronic illness. Furthermore, the American Medical Association (AMA) estimates that by 2030, at least 60.0% of people age 65 and up may have more than one chronic illness. The need for better healthcare facilities, new treatment choices, and drugs will rise as the population ages.

The prevalence of age-related disorders such as Alzheimer's disease, Parkinson's disease, arthritis, and dementia, as well as cardiovascular disease and cancer, is predicted to increase as the worldwide geriatric population grows. This diagnostic imaging services trend is expected to create huge demand for technologically advanced devices.


Increasing Prevalence of Chronic Diseases in the U.S. to Aid the Diagnostic Imaging Services Demand

The increased prevalence of chronic diseases such as cancer and cardiovascular diseases is expected to drive the demand for medical imaging procedures. Medical imaging aids in the early diagnosis of diseases and helps in providing effective disease treatment. As per the National Cancer Institute at the NIH, in 2018, around 1,735,350 new cancer cases were diagnosed in the U.S. Therefore, to combat the increasing disease burden, a large number of medical professionals are using medical imaging devices for imaging services before performing the surgical procedures.

Furthermore, based on CDC’s National Center for Chronic Disease Prevention and Health Promotion (NCCDPHP), chronic diseases are considered one of the leading causes of death and disability in the U.S. It is the leading driver for healthcare costs in the U.S., with USD 3.8 trillion in annual health care costs. Every 6 in 10 adults suffer from chronic diseases, and every 4 in 10 adults are suffering from two or more of such diseases.

Among the most common chronic diseases, heart disease is considered one of the leading causes of death in the U.S. Centers for Disease Control and Prevention (CDC) data indicates that more than 34 million Americans suffer from diabetes, while 88 million adults have prediabetes. Diabetes upsurge the risk in cases of stroke heart diseases and can also lead to kidney failure. The increasing prevalence of chronic diseases, sedentary lifestyle, and growing geriatric population is eventually driving the diagnostic imaging services market in the region.

Increasing Government Regulations Supporting the Insurance Coverage to Boost the Market Growth

Furthermore, increasing government regulation supporting reimbursement policies is expected to enhance the U.S. market. Many modifications in the U.S. regulations has been done to provide diagnostic imaging services to patients with chronic diseases. As per the radiology services reimbursement policy, the allowance for the technical constituent of the initial procedures is 100%. Whereas for the second and further imaging procedures the allowance is 50%. The allowance for the professional component of the primary procedure is 100%. The allowance for the second and subsequent imaging procedure's professional component is 95%. The increasing insurance coverage and favorable government regulation are the major growth drivers of the U.S. Diagnostic Imaging Services Market.


Shortage of Skilled Workforce Affects Penetration of Diagnostic Imaging to Restrict Market Growth

One of the major factors limiting the U.S. market growth is the shortage of a skilled workforce. As per the result of the AAMC public opinion survey, in 2019, around 35.0% of Americans reported that they had difficulty finding doctors from the past three years before the pandemic. In comparison to 2015, this was a 10.0% increase. The major reason for this shortage is physical retirement and a surge in the accessibility to healthcare.

However, based on the AAMC, enrollments by the medical schools have increased by 30.0% since 2002. But the acceptance rates are still low, and selective medical schools such as Harvard accept only 3.8% of the applicants. The average medical school acceptance rate is around 7.0%. Thus, the shortage of skilled workforce seems to be the biggest restraint in the growth of the number of diagnostic imaging procedures being conducted in the U.S. Furthermore, concerns regarding the side effects of medical imaging procedures are expected to restrain the market growth.

CT Segment to Dominate the Market with Holding the Major Shares in the Forecast Period (2021-2028)

The procedure segment can be divided into CT, MRI, X-Ray, ultrasound, and others.

The computed tomography (CT) segment held the largest share in 2020. The segment's dominant market share is owing to the CT scans resulted from the increase in the number of CT scan procedures and its high average price. According to the OECD data, the CT exam procedure in 2017 was 83.3 million, and 91.6 million in 2019 were conducted in the U.S. The growth rate of CT exam procedures in 2019 was around 3.1% over 2018. Furthermore, the increase in the geriatric population has also been attributed to the increased demand for CT scan procedures. For instance, based on the U.S. Census Bureau, the geriatric population aged 65 or above in the U.S. accounts for around 16.5% of the country’s population.

Moreover, there has been a steady increase in the demand for CT scanners ever since the COVID-19 pandemic started. CT of the chest plays an important role in diagnosing COVID-19; almost every patient needs a CT scan to monitor disease progression. Consequently, the rising demand for disease treatment has favored the CT scanners market, even with the deferred procedures. The X-ray segment is the second dominant segment in 2020 due to the product launches with advanced technological features. The MRI segment is estimated to grow at a comparatively lower CAGR in the forecast period.
