Over the past several years, technological advancements have driven the development of more precise and targeted radiation therapy techniques, improved treatment outcomes and minimizing side effects. The market trend is moving toward advanced radiation therapy techniques, such as intensity-modulated radiation therapy (IMRT), stereotactic body radiation therapy (SBRT), image-guided radiation therapy (IGRT) and proton therapy, all which offer enhanced precision and better conservation of healthy tissues. There is a rising demand for integrated oncology solutions that combine radiation therapy with other treatment modalities like surgery and chemotherapy, as well.
According to recent data from Market.us, the global radiation oncology market size is currently estimated to be worth around $8.2 billion, growing to $19.2 billion in 2032, which is a CAGR growth of 9.1%. Seeing these numbers, it comes as no surprise that radiation oncology played a growing role at the Radiological Society of North America 109th Scientific Assembly and Annual Meeting (RSNA23). Here are some of the significant trends discussed on this year’s show floor.
Personalized Medicine
There is a growing emphasis on personalized treatment plans based on a patient’s unique genetic profile and tumor characteristics. This approach aims to optimize treatment outcomes while minimizing side effects.
The Radiation Oncology Program at Children’s Hospital Los Angeles (CHLA) is one such example, and one of only a few facilities in the country to care exclusively for children. The team combines extensive expertise with advanced technology to deliver precision treatments, which aim to maximize cure while minimizing late effects.
CHLA Radiation Oncologist Kenneth Wong, MD, and Medical Physicist Arthur Olch, PhD, FAAPM, work alongside the Children’s Oncology Group consortium to design and implement pediatric radiation clinical trials across the country. In a written statement last December, Olch and Wong, together with Eric Lin Chang, MD, professor and chair of radiation oncology at USC, shared innovations that are impacting pediatric radiation care today.
“We’re entering an era of personalized medicine on all fronts, including pediatric radiation oncology,” said Chang. “We’re going to be refining patient selection based on molecular markers that predict the disease behavior and can help us determine how aggressive or intensive our treatments should be.”
As an example, CHLA is participating in a Children’s Oncology Group clinical trial that is investigating whether radiation doses can be reduced in patients who have a favorable genetic profile for certain cancers.
“The ultimate goal is to select the patients who don’t need radiation therapy at all,” Chang stressed. “That’s difficult to do, and it needs more study, but the hope is that more molecular markers will be available to help us make these decisions and personalize care for each child.”

Recently, iCAD, Inc., a global medical technology leader in innovative cancer-detection solutions, and CancerIQ, a precision cancer prevention platform streamlining provider workflows and activating high-risk patients, announced a new partnership to create a best-in-class breast healthcare solution. The companies report the partnership will provide a seamless way to uniquely inform physicians and patients of cancer risk — which includes lifetime, genetic and AI-detected near-term risk — identify breast cancer at earlier stages when treatments will work best, and increase patient adherence to personalized care plans.
iCAD noted that these solutions will combine elements of its artificial intelligence (AI)-enabled ProFound Breast Health Suite with CancerIQ’s software and services. This will reportedly give users a 2.4x more accurate prediction of breast cancer risk, by combining AI-informed 1- or 2-year risk with lifetime risk, as well as a unique care management and patient activation workflow solution.
“This partnership will streamline how patients and physicians use our collective health data to schedule preventive screenings and manage breast health care in a way that will save lives,” said Dana Brown, president and CEO of iCAD, in the same statement. “We look forward to a long-term relationship with CancerIQ that will create meaningful, actionable information in terms of proactive and personalized care benefiting both medical providers and the patients they serve.”

Value-based Care
Healthcare systems have increased their focus on providing value-based care, helping to improve patient outcomes while managing costs effectively as efforts are made to enhance treatment efficacy while reducing unnecessary procedures and expenses.
Today, prostate cancer and Alzheimer’s Disease are prevalent, and GE HealthCare’s AIR technologies that are incorporated in the Signa PET/MR Air scanner help directly impact these, and other challenging diseases, that are difficult to diagnose and treat.
The combination of prostate-specific membrane antigen (PSMA) targeted positron emission tomography (PET) radiotracers with GE’s high sensitivity PET and the anatomical precision of magnetic resonance imaging (MRI) in the Signa PET/MR Air holds the potential to help clinicians make a more precise diagnosis and staging/re-staging of prostate cancer, according to the company.
The recent approval of PET amyloid tracers and new Alzheimer’s treatments require imaging of patients with MRI and PET. Signa PET/MR Air offers a sensitive time-of-flight (ToF) PET detector in a PET/MR, helping to enable clinicians achieve early diagnosis, track disease progression and detect adverse side effects in a single scan. According to the company, the system delivers deep learning-based MRI image reconstruction with AIR Recon DL, helping to ensure both improved image quality and up to 50% reduction in scan time.
MotionFree Brain PET on the Signa PET/MR Air addresses and manages patient movement during imaging, without external tracking devices. Images affected by motion on the Signa PET/MR Air can be corrected even after the patient has left the scanner.

Artificial Intelligence Integration
Artificial intelligence (AI) is becoming more integrated into everyday healthcare, and machine learning is being utilized to analyze complex data, aid in treatment planning, automate tasks and improve treatment outcomes by assisting in decision-making processes, just to name a few benefits.
Philips is leveraging the power of AI-assisted technology in its MR SmartSpeed image reconstruction software. In a newly announced partnership, Philips and Quibim are working on an integrated solution that includes Quibim’s AI-based QP-Prostate software to help automate real-time prostate gland segmentation in MRI images. According to the company, this will generate meaningful quantitative insights, and standardize MRI prostate exam reporting. When combined with Philips’ AI-based MRI imaging techniques, the solution’s goal is to provide clinicians with the speed and precision needed to deal with the growing number of patients in need of MRI exams, and to proceed with these exams with diagnostic confidence, personalized treatment and ultimately better outcomes.
“This collaboration with Quibim is the latest example of our commitment to build an AI ecosystem into our diagnostic imaging portfolio to help detect conditions like cancer earlier, improve the rate of accurate first-time-right diagnosis and streamline hospital operations to provide better care at lower costs,” said Ruud Zwerink, general manager of MR at Philips, in a written statement centered around RSNA23. “The collaboration with Quibim will ultimately be extended to address other forms of cancer beyond prostate, where there is a need to improve efficiency and mitigate staff shortages while delivering high-quality oncology care to an increasing number of patients.”
