Size, Share, Trends, and Forecast of the Pet CT Scanner Device Market, 2026

 

Pet CT Scanner Device Market

Positron emission tomography (PET) is a type of nuclear medicine imaging that is also known as PET imaging or a PET scan. It evaluates organ and tissue functions by using small amounts of radioactive materials known as radiotracers or radiopharmaceuticals, a special camera, and a computer. It can detect disease at an early stage before other imaging tests by detecting changes at the cellular level.

It can detect heart disease, cancer, gastrointestinal, endocrine, and neurological disorders, among others. Its radiotracers typically accumulate in tumours or areas of inflammation and bind to specific proteins in the body. F-18 fluorodeoxyglucose (FDG), for example, is a common radiotracer that is absorbed by cancer cells.  Further, it can be detected in the area of examination at the time of imaging. It has various advantages to use like it gives greater detail with higher level of accuracy. Moreover, it provides greater convenience for the patient who undergoes PET-CT scan. 

The global PET-CT Scanner Device Market size was valued at US$ 1.9 billion in 2017 and is expected to witness a CAGR of 5.1% over the forecast period (2018 – 2026).

During a single imaging session, a positron emission tomography (PET) - computed tomography (CT) scan reveals information about the structure and function of cells and tissues in the body. In recent years, the majority of PET scans have been performed on instruments that combine PET and CT scanners. PET-CT scans combined provide images that identify the anatomic location of abnormal metabolic activity within the body. It has been demonstrated that the combined scans provide more accurate diagnoses than the two scans performed separately.

PET and CT scans are required for the diagnosis of various diseases such as cancer, heart disease, and certain brain disorders. PET scanners detect metabolic activity, whereas CT scanners reveal anatomical details. The risk of poor superimposition of separate imaging is reduced, and the hybrid PET-CT process reduces patient burden by simplifying scanning. PET-CT scanner hybrids combine the strengths of two well-established imaging modalities and aid in accurate disease diagnosis, localization, and monitoring. Furthermore, PET-CT scanners can capture images in record time (less than a minute).

The growing global prevalence of infectious and chronic diseases such as cancer and heart disease, as well as the increasing demand for effective diagnostic systems, are expected to drive the PET-CT scanner market size. Heart disease is the leading cause of death in the United States, killing over 600,000 people each year, according to the National Center for Health Statistics. According to the International Agency for Research on Cancer (IARC), 14.1 million new cancer cases were reported globally in 2012. Lung cancer (13 percent), breast cancer (11.9 percent), and colorectal cancer were the most common types of cancer among these (9.7 percent ). According to the Centers for Disease Control and Prevention (CDC), February 2018 data, around 22,000 men and 9,000 women suffer from liver cancer, and around 16,000 men and 8,000 women die due to liver cancer, every year in the U.S.

Because of altered blood sugar or blood insulin levels, the PET-CT scan test results of diabetic patients or patients who consumed any food a few hours before the examination may be affected. A person who is extremely obese may not be able to fit into the opening of a traditional PET-CT unit. When compared to standard PET, motion artefacts could be a major issue with PET-CT imaging. Furthermore, due to the harmful radiation that causes side effects in the body, this scan is not recommended for all patients, including pregnant women. All of these factors can have a negative impact on the growth of the PET-CT scanner device market.
